Seasonal Bear Creek winds about a mile through this working horse ranch, with cottonwoods, shrubs and grassland habitats providing outstanding birding, especially during migration. Two ephemeral ponds attract a variety of waterfowl and water birds after rains. Conveniently located just west of US Hwy 297/385 the ranch is home to Blue Rose Ranch Horse Rescue and Adoption. An optional high-end B&B with meals and hot tub, horse training, horseback riding, and tours of the Horse Rescue and horse interaction are available.
Eastern Plains
This trail, based in Fort Collins, allows easy access to almost every habitat in northern Colorado, from high-elevation forest to high-quality shortgrass prairie. Some of the sites here are right in the middle of town; some are breathtakingly remote.
Just south and west of Denver are some “roads less traveled” that traverse scenic canyons, oak scrublands, conifer forests, and old burn scars in the foothills. This trail is for those who want to get off the beaten path without traveling far.
Some places on the plains are an acquired taste, but this is not one of them. This is what Southeast Colorado is all about.
Thanks to decades of open space preservation and land conservation, the Boulder area is packed with places to view wildlife. Boulderites love the outdoors, and if you come to visit, you’ll immediately see why.

This trail encompasses the parks and waterways of northeast urban Denver, plus a large swath of the adjacent plains, stringing together the finest spots to enjoy nature right in the shadow of the city.
Wray Area
One of the largest towns on the eastern plains, Wray is a great town from which to base yourself when birding in the area. Wray Prairie-Chicken Viewing Tours take place in March and April each year, a cooperative effort of the Wray Museum, Wray Chamber of Commerce, Kitzmuller Ranch, and Colorado Parks and Wildlife–see the website for details. The best birding in Wray is in Rainbow Park and along the river nearby. Rainbow Park contains a small but dense cluster of coniferous and deciduous trees that has hosted wintering sapsuckers and could attract migrants. Here and around town look for eastern species like Red-bellied Woodpecker, Eastern Bluebird, Mississippi Kite, and others. Although Wray is very nice, the best birding in the area is northwest of town, at the Wray Fish Hatchery and the adjacent Stalker Lake SWA. Some small ponds, riparian and juniper hedgerows, and weedy gullies make these locations a good place to lookf for sparrows, Northern Cardinal, and other landbirds, and assorted waterbirds. Muskrat and coyote might be seen in the area.
Limon
Limon is a major population center in east-central Colorado, with all the basic services. You might find some migrant landbirds in the trees around town, especially the patch just behind (north of) the Events Center. However, the highlight of birding in Limon is the Limon Wetlands, which are reached via the Doug Kissel Fishing Ponds. A paved trail extends south half a mile to an interpretive kiosk and gazebo overlooking the wetlands, which in summer host Sora, Virginia Rail, Belted Kingfisher, Yellow-headed Blackbird, Great-tailed Grackle and Ruddy Duck, not to mention muskrats and various amphibians and reptiles. The fortunate might encounter an Ornate Box Turtle crossing the bike trail in summer, or see coyotes or deer along the path.
Flagler
The town of Flagler is just about the only spot in the area with a place to stay and to stock up on food. The many large trees around town can be good for birds, and the small pond on the golf course just south of town often holds a few ducks.
La Junta
The largest town in southeastern Colorado is also a fine birding town, with a good sized city park, many large trees, and a good cemetery with many conifers. The town park, which has many large but sparse trees and a small pond, is worth a look in migration. The small pond in the middle of the park often has some ducks on it, and is a reliable spot to see Wood Duck. Fairview Cemetery, on the west side of town, has many large conifers, though no undergrowth, and sometimes has winter finches in good years, and could also be good for migrants. Mississippi Kites have nested both here and at the town park.
Leininger Ranch
The Leininger Ranch is private property that lies 10 miles south of La Junta and offers thousands of unexplored acres of shortgrass prairie, cedar-lined bluffs and canyons, and numerous stock ponds and arroyos. Birds of the Leininger Ranch include shortgrass specialists such as Burrowing Owl, Ferruginous Hawk, and Scaled Quail. The ranch also has Greater Roadrunner and has in the past had Vermilion Flycatcher. A short drive from Highway 50 and the town of La Junta makes the Leininger Ranch the ideal place to spend the day exploring close to the creature comforts of town. Please make reservations in advance of visiting by contacting Zane and Barb Leininger at (719) 384-9634 or Barzl1@hughes.net.
Box Springs
Box Springs consists of a very small pond surrounded by only a couple of trees, but it is private property on all sides. This location so isolated that it frequently attracts great birds. Look for ducks, Black-crowned Night-Herons, and the occasional migrant warbler in the cottonwoods. If you’re lucky, you might see a rail or a bittern, or you might discover a Mountain Plover on the surrounding plains.
Eads
The largest town in Kiowa County is a good spot to stop for lunch or as a base for birding the area. While here, there are a couple of good spots to check out. The small town park should be checked for migrants. The waste water lagoons, just just south of town, are private protery and no access is allowed. South and west of the waste water lagoons is Jackson’s Pond, a natural recreation site including, hiking, biking, wildlife viewing, fishing and more. Look for waterfowl, deer, kingfisher, raptors, shorebirds and more wildlife along the shore of the pond and Kiowa Creek at this site.
Lamar
The town of Lamar, one of the largest towns in Southeast Colorado, is also famous as one of the best birding destinations in the state. From this base you are less than an hour away from such excellent locations as the Indian Reservoirs, John Martin Reservoir, and Two Buttes State Wildlife Area. However, you don’t need to leave town to see great birds. Willow Creek Park has breeding Mississippi Kites in summer. The woods behind the Lamar Community College and the woods behind the high school are legendary migrant traps, as is Fairmount Cemetery. Sometimes the Community College woods will host eastern birds such as Northern Cardinal or Red-bellied Woodpecker, and mammals including muskrat and skunk. Inca Doves have recently begun to colonize the town, although their numbers are quite low and you will be lucky to find one. Every February, Lamar hosts a Snow Goose Festival which is one of the largest birding festivals in the state.
River Bluffs Open Space
A small but scenic open space, River Bluffs’ location adjacent to the Poudre River provides ideal habitat for waterfowl and wading birds. Bald Eagles, Golden Eagles, and owls call this area home, and Red-tailed Hawks and Great Horned Owls have been found nesting in the park’s cottonwoods. An active Bald Eagle nest can be found about 1/4 mile away on an adjacent property, so keep your eye on the sky! As part of the Poudre River Trail, the path here joins to the larger 21-mile (east to Greeley) system, allowing for endless outdoor explorations and discoveries.
Castlewood Canyon State Park
This beautiful state park is one of the best places to bird near Denver. It would be easy to spend most of a day birding here, and the best time to visit tends to be in late spring through summer. An extensive trail system runs through the canyon and allows access to a variety of habitats including scrub oak woodlands, montane forest, and grasslands. Canyon Wrens sing and White-throated Swifts fly above as as you walk in the canyon. Trails continue through scrub oak woodlands, where you can spot Ovenbird and Common Poorwill. The montane forest is rich with Stellar’s Jay and Cordillerean Flycatcher and in the grasslands, look for Western Meadowlark and Vesper Sparrow.
Many birds nest and raise their young in the park; a unique dry-land heronry even once occurred in the park, where Great Blue Heron nested. Several raptors may be observed as well, including Swainson’s Hawk, Cooper’s Hawk, Red-tailed Hawk, and several falcon species, such as American Kestrel. Also keep your eye out for Lazuli Bunting, Virginia’s Warbler, Woodhouse’s Scrub-Jay, Plumbeous Vireo, and Bushtit.
Castlewood is home to one of Colorado’s larger Turkey Vulture populations; they are a common sight riding thermal updrafts created as the rocks warm each morning. The park celebrates their return from migration with Welcome Back Turkey Vulture Day each spring. A State Parks pass is required for entry.
Boulder Reservoir
Anyone looking for waterbirds in Boulder County must make sure to check Boulder Reservoir, especially in autumn. The long list of rarities that have been found here in fall include Red-necked Grebe, Pacific Loon, Arctic Tern, Long-tailed Jaeger, and Ruff. More likely finds include Osprey, Bald Eagle, Forster’s Tern, and California Gull. Also consider visiting the adjacent Coot Lake for more viewing opportunities. Note: dogs are not allowed from May 15 – Labor Day. An entry fee is charged from April – October.
Bear Creek Greenbelt (Jefferson portion)
Many of Denver’s greenbelts are beautiful riparian corridors with established bike and walking paths, but none are quite as impressive as the Bear Creek Greenbelt, one of the best forested creek-lines in the metro area. You would even be forgiven for thinking you were in the eastern US while walking along it! Therefore, the potential for migrants is quite high, and a spring or fall visit could be quite productive. Summertime has fewer total species, but you could still find Great Horned and Eastern Screech Owls (at night), Bullock’s Oriole, Yellow-breasted Chat, Western Kingbird, and Lazuli Bunting, among others.
In winter, overall activity is much lower, but sparrow flocks are still around, and this would be a good place to scan through White-crowned Sparrows for one of the rarer possibilities such as Harris’s Sparrow. The greenbelt is also well connected to the trail network that criss-crosses the Denver area, so you could combine this area with several other sites reachable by bicycle if you want to make a longer day of exploring.
Lower Latham Reservoir
Lower Latham Reservoir itself is private and very difficult to see from the road. However, the extensive marshes along the south side of the reservoir are an excellent birding destination. Even though you must stay on the county road, you can still get up close and personal with the likes of Yellow-headed Blackbird, Western Marsh Wren, Savannah Sparrow, Great-tailed Grackle, Sora, Virginia Rail, and Black-necked Stilt. American Bitterns nest here but are hard to see; White Pelicans also nest here. Keep an eye out for other marsh-dwelling creatures such as muskrats. Be sure to respect private property and pull off as far as possible on the gravel road.
Jackson Lake State Park
Jackson Reservoir is the king of birding spots in the greater Fort Morgan area, offering everything from large rafts of waterfowl, to enormous congregations of shorebirds, to some of the best migrant traps around. Time of year plays an important role here, with spring usually having very high water (and thus less shorebird habitat), and fall offering the best overall variety. The cottonwood groves in the State Park are best for songbird species (especially during spring and fall migration), while the best access to the lake itself depends on the water level.
In the forested groves of the campgrounds, look for warbler and vireo species during spring and fall, and flocks of robins and the occasional waxwing during winter. Breeding birds such as Bullock’s Oriole, Western and Eastern Kingbirds, and many others occur during summer months. Long-eared and Great Horned Owls can also be heard during the late fall and winter.
If you’re adventurous, stop at the outlet canal parking area at the south end of the reservoir, where you can walk along the dam for a long way to reach the best viewing. When the water is low, the dry margins of the lake bed are a good bet for Mountain Plover and other shorebird species during early fall migration, and various sparrow species lurk in the emergent growth.
A State Parks pass is required for entry and hunting occurs at this State Park, so be sure to check for seasonal restrictions before visiting.
If you plan a longer stay in the area and are a fan of James A. Michener’s book Centennial, the town of Orchard, where the miniseries was filmed, is only about 5 miles away. However, most remnants of the production sets are now gone.
Crown Hill Park and Crown Hill Cemetery
Crown Hill Lake, in the park of the same name, is a good place to look for geese and diving ducks, including Red-breasted Mergansers in winter. A couple of groves on the north side of the park are worth birding; one is the fenced wildlife preserve around Kestrel Pond in the northwest corner of the property, which is closed to protect nesting birds from March to June. During the closure, the only access to this area is during guided nature walks scheduled by Jefferson County Open Space. Several blocks east of here is a shelterbelt of mature cottonwoods and underbrush, best accessed from a small roadside pullout on the south side of 32nd Avenue near Estes. This shelterbelt should be checked in spring and fall for migrant land birds. East of the park and lake is the massive Crown Hill Cemetery. Bird the evergreens in winter hoping for irruptive species like crossbills, Cassin’s Finch, Evening and Pine Grosbeaks, and Bohemian Waxwing. Also check for various warbler species during the spring and fall.
Duck Creek State Wildlife Area
Duck Creek has one of the best migrant trap habitats in the area, but is often neglected in favor of more popular locations nearby. However, it is well worth a visit, especially during spring and fall migration when you never know what could show up! Several of the northeastern specialty breeding species occur here, including Baltimore Oriole, Eastern Kingbird, and Upland Sandpiper (along the entrance road). During the winter, it tends to be fairly quiet, but flocks of sparrows may be around. Hunting occurs on this property, so be sure to check for seasonal restrictions before heading out.
Frederick Recreation Area
The rocky-shored Frank Milavec Memorial Lake is popular with fishermen and recreational walkers, but also with ducks, grebes, pelicans and cormorants, particularly in late fall and early spring. The lake is ringed by a gravel walking trail that affords excellent viewing at any time of day. The southeast corner of the walking trail borders a marsh that is home to Red-winged Blackbirds and rails. Paved trails also run along a tree-lined creek where Yellow Warblers and Downy Woodpeckers breed.
Roxborough State Park
Located just south of Chatfield State Park, Roxborough is a world away in terms of landscape and habitat. The views at this park are dominated by the panoramic hogback formations of the Colorado front-range. Habitats of this beautiful park include excellent examples of rocky cliffs, mountain shrubland, and open prairie, with riparian wetlands and coniferous forest in the mix.
Miles of hiking trails offer ample opportunities to view Canyon Wren, Rock Wren, and a variety of raptor species along the hogback formations. Oak woodland birds include Broad-tailed Hummingbird, Virginia’s Warbler, Woodhouse’s Scrub-Jay, Ovenbird, and other foothill species. Mixed-grass prairies within the park support Horned Lark, Western Meadowlark, and Lark Sparrow. The smaller riparian groves are worth checking during migration – look for Warbling Vireo, Gray Catbird, and Lazuli Bunting. Springtime is also excellent for viewing a wide variety of butterfly species. The park is also designated as a National Natural Landmark and an Important Bird Area through the National Audubon Society. Please be aware dogs and bikes are not allowed at Roxborough. A State Parks pass is required for entry.
Lowell Ponds
Don’t let their location right by the interstate fool you: these small ponds, formerly a State Wildlife Area, can often be full of waterfowl. Migration times tend to be best, but during the summer, several breeding species should be present. The associated riparian habitat may also have migrants in season.
Springfield
The largest town and county seat of Baca County has some trees worth checking for migrants in season. Mississippi Kite, Great-tailed Grackle and Chihuahuan Raven have been observed here. Check especially the trees in the city park (two blocks west of Main between 4th and 5th) and around the Baca County Courthouse (on the west side of Main between 7th and 8th). You may see Turkey Vultures around the water tower, and the grain silos attract dove and pigeons. The water treatment plant, just outside of town, may be worth a visit, especially in winter. The only hotels in all of Baca County are here.
Greater Prairie-Chicken areas
The sandsage prairie just north of Wray contains the vast majority of Colorado’s Greater Prairie-Chickens. The only reliable lek locations at this time are located on private lands. Several groups and ranches operate tours to see the chickens on their leks in spring, and this is by far your best shot at seeing the birds; see the website for details. If you are are really strapped for time, you can look for the birds along the county roads north of Wray and east of US 385 just after dawn in April and May. The chickens are easy to hear from the road but often difficult to see – most of the leks are on the far side of the numerous hills! No matter how close the birds sound, DO NOT LEAVE THE ROADS.
Calkum Ranch
Located only an hour from metro Denver, the Calkum Ranch offers a unique and quick getaway from the hustle and bustle of the Front Range. The Calkum Ranch lies just west of Limon and north of Interstate 70 in an area of juniper breaks; the park-like setting of the juniper trees and sandstone formations makes the ranch an ideal escape for birders and rockhounds alike. The vistas from atop the breaks alone make the trip worthwhile, while the abundance of various habitats makes it an outstanding birding site, particularly during spring and fall migration. Horseback riders are welcome with their own horse.
Mossland Memorial Golf Course
Enjoy a round of golf as well as watching birds at Flagler’s golf course! This property contains a 9-acre lake and surrounding marsh area in a location with otherwise sparse water resources. Look for the specialties Ruddy Duck and Black Tern in addition to other migrant and resident wildlife.
Bent’s Old Fort and Oxbow State Wildlife Area
The reconstructed Bent’s Old Fort along the old Santa Fe Trail is the focus of a National Park where actors in period costume maintain a fascinating piece of ‘living history.’ The park preserves a nice area of riverbottom cottonwood forest along the Arkansas as well as some open grassland and the terrific marsh where Black Rail was first found in the state. There is also an excellent riparian corridor along the river. Adjacent to the fort property to the east, both north and south of the river, is the Oxbow SWA, which contains more acreage of riverbottom habitats. Access to the SWA is from the south side of the river.
Vogel Canyon
This scenic out-of-the-way spot features picnic sites, interpretive signs and rock art. For birds, the main attraction of this medium sized canyon are the two permanent springs at the bottom of the canyon about a mile from the parking area. The riparian habitat here could attract migrants in season. Almost every regular southeast dryland species occurs here, including Eastern Phoebe by the water, nesting Great Horned Owl, and Common Poorwill. The habitat here includes, in addition to the springs, pinyon-juniper, rimrock and cliffs and extensive cholla grasslands with pronghorn, jackrabbits, coyotes and box turtles. Four hiking trails provide access to all the habitats.
Lake Henry
Lake Henry is a jewel of a birding spot. The lake and its shore attract large concentrations of waterbirds, especially in migration and winter. Look for American White Pelican, herons, cormorants, gulls and terns. In migration, look for shorebirds including Sanderling and Willet. Burrowing Owls nest in the large prairie dog town along the entrance road. If you are up for a hike of nearly a mile, you can walk north from the west end of the dam to an excellent grove of trees that often attracts migrant landbirds, including many rare eastern warblers and large numbers of sparrows. The area north of the gate is private property, but the owner allows access to birders. In addition to birds, animals including pronghorns, coyotes, and foxes may be seen here. Note: do NOT drive the dam road if it has rained recently.
Kit Carson
Kit Carson can be a surprisingly good birding town. Its shade trees can attract migrants; the best trees are in the southwest quadrant of town, and on the east edge of town north of US 40. Just southeast of town on both sides of CR 20 is an enormous prairie dog town which has Burrowing Owls in summer. A little farther south on CR 20, a bridge crosses Big Sandy Creek (usually dry). All the land is private, so be sure to bird only from the bridge, which will put you at mid-tree level in a tall cottonwood forest. Look and listen here (mostly in summer) for Eastern Bluebird, Red-headed Woodpecker, Orchard and Bullock’s Orioles, Eastern and Western Kingbirds, House Wren, Yellow Warbler, Great Crested Flycatcher, Chimney Swifts, and migrant flocks in season. The private sagelands south of the creek along the road are home to Scaled Quail, Cassin’s Sparrow and Lark Bunting, but again you must bird from the road. Rattlesnakes, coyotes and skunks may be seen in the area, not to mention the ubiquitous pronghorn! Approximately 30-50 wild turkeys call Kit Carson home from fall to early spring. You’ll see a mix of Merriam’s, Rio Grande, and hybrids of the two.
Mike Higbee State Wildlife Area
This small State Wildlife Area doesn’t look like much, but the hedgerows around the maintenance buildings can attract large flocks of sparrows, and the reeds along the creek support Virginia Rail, Sora, Green Heron, Belted Kingfisher and Common Yellowthroat. You might also see Blue Grosbeak, Orchard Oriole and Northern Bobwhite, in addition to muskrat and thirteen-lined ground squirrel. Look for amphibians in the wet areas, and for mule and white-tailed deer, red fox, rabbits and coyotes in the brush.
CSU Environmental Learning Center
The mission of Colorado State University’s Environmental Learning Center includes connecting people to nature and advancing the field of environmental education. With over 200 acres of cottonwood forest, riparian areas, and prairie grasslands, and crisscrossed by a few dirt trails, the ELC provides great opportunities to observe a variety of birds and other wildlife. Breeding birds include Great Horned Owl, Lazuli Bunting, Blue Grosbeak, and Common Yellowthroat. In migration, flocks of migrant warblers can sometimes include rarities; a Blackburnian Warbler was once seen here. Several species of waterfowl can be found on the ponds, especially in winter. Please note dogs are not allowed at this property.
Gateway Mesa Open Space
With a similar environment to Castlewood Canyon, this open space is a pleasant place to experience scrub oak and rimrock habitats south of the Denver metro area. These habitats are home to migratory birds, raptors, and Wild Turkey, among many others. Three trails lead you to explore the area; look for birds like Rock and Canyon Wrens, Woodhouse’s Scrub-Jay, Virginia’s Warbler, Ovenbirds and Bushtit. Be sure to check out the forested canyon on the south edge of the open space, where you can find Mitchell Gulch (a tributary of Cherry Creek) and head out on the Mitchell Creek Canyon Trail for more discoveries.
Twin Lakes Open Space
These two lakes rarely attract many interesting waterbirds, but the trees around them can be great in spring migration for warblers, flycatchers, and other migrants. Interesting birds here have included Eastern Bluebird, Eastern Phoebe, Gray Flycatcher, and Northern Waterthrush. A well-known pair of Great Horned Owls nests in a hollow snag just across the creek from the path. In spring, when the young become visible in the nest, it is common to find a gaggle of owl-watchers blocking the trail. Note that West Lake is an off-leash dog park.
Bear Creek Greenbelt (Denver section)
The Bear Creek Greenbelt has one of the best riparian corridors within the city limits, and is an excellent place to spend a spring or fall morning walking or while on a bike ride. Like many greenbelts in the city, the site is connected to a large bike trail system, and you can spend as much time as you like exploring the area without ever having to get in a vehicle. The summer months tend to be a bit quieter, but local breeders like Yellow-breasted Chat and Lazuli Bunting are possible. Great Horned Owl is around all year, and a nighttime visit may turn up an Eastern Screech-Owl.
Greeley
In this Great Plains City, the best place to bird is Glenmere Park. The pond in the park attracts ducks and geese, and Snowy Egret and Black-crowned Night-Heron have nested on the island in the pond. Mississippi Kite have sometimes been seen in and around the park in late summer and early fall, and migrants can be attracted to the mature trees. Sanborn Park is another lake-based park that has a cove on the SW side that can have wood ducks, etc. There is a separate listing for the Cache LaPoudre Trail on the north side of the City.
Wheat Ridge Greenbelt
Long famous as Denver’s best migrant trap, the Wheat Ridge Greenbelt has some of the best riparian habitat in the metro area. It is also relatively compact for a greenbelt, with the best opportunities concentrated along Clear Creek between Youngfield and Kipling streets. This area encompasses mature cottonwood forest, four good-sized ponds, and quite a bit of brushy marsh and swampy second growth. The best time to visit is obviously during migration, when nearly anything can show up. Of the regular species, look for Plumbeous and Cassin’s Vireos, Virginia’s, MacGillivray’s, Orange-crowned, and Townsend’s Warblers, and just about any of the regular Front Range sparrow species. Eastern Screech-Owls occur here as well; the most reliable spot seems to be at the eastern end of the greenbelt. The winter is, as expected, much slower, but a determined observer may see a few interesting species.
Tamarack Ranch State Wildlife Area
While you won’t see many tamarack trees here, this large SWA is the best spot in northeastern Colorado to search for the full suite of northeastern specialties. Search particularly in the denser riparian habitat to the north of the road and south of the river for Northern Cardinal; Baltimore Oriole (as well as hybrids of all sorts); Eastern, Spotted, and everything-in-between Towhees; Red-bellied Woodpecker; and Bell’s Vireo. The more open country to the east of CO 63 could have Field Sparrow, Red-headed Woodpecker, and Upland Sandpiper. In the winter months, flocks of sparrows might include Harris’s Sparrow, and Rough-legged Hawks are sometimes found hanging out in the area. Hunting occurs on this property, so be sure to check for seasonal restrictions before heading out.
St. Vrain State Park
Located along the St. Vrain River, this state park provides excellent birding. St. Vrain features numerous ponds and small lakes, marshes, willow thickets, fields, and stands of cottonwoods that provide rich and varied habitat for birds. Winter bird viewing includes Bald Eagle and various waterfowl, such as Teals, Buffleheads, Gadwalls, and Mergansers. St. Vrain is a great place to see Western and Clark’s Grebe, several species of swallows, Osprey, and White Pelican. American Kestels, Orioles, Grosbeaks, and Chats are also known to nest in the park. St. Vrain was once known as having the largest rookery of Herons and Egrets in Colorado. A State Parks pass is required for entry.
Waterton Canyon
This gem of a canyon, just south of Chatfield State Park, ranks among the best places in the Denver metro area to get out and experience foothill birding. A wide and well-maintained trail starts at the lower end of foothill scrub and follows the South Platte River, lined with a beautiful riparian corridor, up for many miles into ponderosa woodland. Most people tend to stick to the lower few miles, which makes for a good few hours of birding. In the scrub habitat along the trails and on the canyon slopes, look for Virginia’s Warbler, Lazuli Bunting, Spotted Towhee, and Say’s Phoebe. The taller trees along the river usually have quite a few Yellow-breasted Chats, Cordilleran Flycatchers, and even a few Least Flycatchers.
The river itself is home to several pairs of American Dippers, and Common Mergansers use the nearby cliffs to nest. Canyon and Rock Wrens are also common here. If you do make it up into the pine forest, check for the typical suite of ponderosa-loving species, including Williamson’s Sapsucker. A nighttime walk in the canyon may produce Eastern Screech and Great Horned Owls. Migration time may produce any number of species passing through, but the winter tends to be fairly slow and limited to a few sparrow flocks and hardy resident species. The canyon is also good for mammals, and people often see bighorn sheep here. Please never approach sheep and observe all wildlife from a safe distance. Be sure to also check for a wide variety of butterfly species during the spring and summer.
Jim Baker Reservoir and nearby ponds
This small reservoir has good access provided by a trail around the lake, and can hold various waterfowl species during migration. A small cattail patch should be checked for Virginia Rail and Marsh Wren, and the scrub and riparian habitat for migrants such as Orange-crowned and Wilson’s Warblers, and various sparrows, in season.
Ponds on the east side of Lowell are private. Good views of the ponds and rookery can be obtained from the public sidewalk or high points along the trail at Jim Baker.
Jackson Lake State Wildlife Area
Jackson Lake State Wildlife Area offers great birding opportunities for shorebirds and waterfowl along the north side of the reservoir. Everything from large rafts of waterfowl, to enormous congregations of shorebirds, to some of the best migrant traps around. Time of year plays an important role here, with spring usually having very high water (and thus less shorebird habitat), and fall offering the best overall variety. Access to the lake itself depends on the water level and time of year. Boating is allowed, though there isn’t an established boat ramp. When the water level is low you can walk through the small grove of trees (from the parking area) and onto the lake bed itself. The dry margins of the lake bed are a good bet for Mountain Plover during early fall migration, and various sparrow species lurk in the emergent growth. There are fishing limitations and hunting occurs on this property, so be sure to check seasonal restrictions before visiting.
Carrizo Canyon Picnic Area
A large permanent spring and a good lowland-riparian grove make this a great site. Along with picnic sites, interpretive signs and rock art, there is also some good pinyon-juniper forest and yucca grassland. Birds are similar to those at Cottonwood Canyon. This can be an excellent area for reptiles and amphibians, including softshell turtles.
Lazy LW Ranch
Nestled in the sandhills northwest of Wray, the Lazy LW offers hiking and birding among the sandsage in Greater Prairie-Chicken country. The Wilsons have a Greater Prairie-Chicken lek on their property and have developed a grazing system to encourage nesting. The shelterbelts around the homestead offer good birding and are a reliable spot for Loggerhead Shrike and Northern Bobwhite.
Ridge Road (CR 99 and CR 101)
This scenic road is an excellent place to look for Cassin’s Kingbird, as well as other grassland species amid the yucca covered hills. Some ponderosa groves can provide Mountain and Western Bluebirds. Coyotes and foxes may be seen hunting in the grassy areas.
Grimes Ranch
This is a large ranch with shortgrass prairie, miles of frontage on Sand Creek, and unique bluffs that rise more than 50 feet above the creek bed. As this is some of the only topography in the area, birders might want to check the high areas for Sprague’s Pipit in spring and fall migration.
Las Animas State Fish Hatchery
The two ponds in this complex can be good shorebird locations when the water levels are appropriate. In season, waterbird potential is high as well. The ponds on either side of CR 5.5 a mile and a half south of the SFU can be excellent for grebes, egrets, rails and even American Bittern; watch for muskrats also.
Higbee Cemetery
A small cemetery set amid cholla and pinyon-juniper covered hills and mesas. A few cottonwood trees and some agricultural fields add to the mix. Greater Roadrunner, Ladder-backed Woodpecker, Curve-billed Thrasher, Scaled Quail, and Rufous-crowned Sparrows are some of the possibilities. Vermilion Flycatcher nested here for a couple of years. The canyons and rimrock in the area contain some spectacular mammals, and even scorpions and tarantulas.
Gray Ranch
The Gray Ranch is located along the south and west shores of Lake Meredith, one of the finest shorebird and waterbird hotspots in Colorado. Although some excellent rarities have been found at Meredith (including Ruff!), the lake has received scant coverage over the years because most of its expansive shores are privately owned. With the opening of the Gray Ranch to wildlife watching, Lake Meredith is now far more accessible to birders, who should turn up good birds galore on this property. The ranch offers primitive camping along the south shore of Lake Meredith. On your way into the lake, watch for Burrowing Owls and other shortgrass species as you pass through multiple black-tailed prairie dog colonies. For more information and access, call or stop by JR’s Country Store in Ordway: (719) 267-3262, at least 48 hours before your visit.
Cheyenne Wells
This is the county seat and largest town in Cheyenne County. It has a number of trees which can produce birds like Eurasian Collared-Dove and Great-tailed Grackle as well as the occasional good migrant. Northern Harriers soar above nearby open fields. Large flocks of migrating Lark Bunting can be found along county road surrounding town. Food, lodging and gas can be found here.
Granada
Granada has some large shade trees that can attract good flocks of migrant landbirds in spring and fall; pronghorns and prairie-dogs can be seen in the surrounding countryside. Just southwest of town is the site of the Amache Japanese Internment Camp, which has many small trees but is worth visiting not so much for its wildlife potential as for its sobering historical significance.
Riverbend Ponds Natural Area
Right across the street from Cottonwood Hollow Natural Area, this natural area is very similar, with open, brushy ponds and a network of winding trails. The tall trees of the Cache la Poudre River corridor run down one side of the property, so keep your binoculars handy! Also look for ducks and geese, especially in the colder months, and for migrant warblers, wrens, and sparrows in the thickets in spring and fall. This natural area is a good place to find Osprey, Great Blue Heron, Eastern Kingbird, and possibly Green Heron in summer.
Salisbury Park
With a trail along Cherry Creek, Salisbury is a nice spot to look for birds. This park has patches of woodland and a nice small pond and is best during migration, when any number of species could show up. The pond itself often has quite a few ducks on it during the fall and early spring, and the open habitats sometimes have sparrow flocks and the odd Northern Shrike. Be sure to check out the Parker Arboretum, where the town of Parker grows a variety of trees that may one day take root in one of the parks.
East Boulder Trail – Gunbarrel Farm/ White Rocks Trail
The open space and White Rocks Trailhead provide access to the same area from two different directions. In the north, the open land rises on a high prairie bluff and is one of the best places in the area to find nesting Grasshopper Sparrows in summer, along with the likes of Western Kingbird, Horned Lark, and Blue Grosbeak. Traveling south, the trail drops down to cross the creek, where Tree Swallow, Warbling Vireo, and Bullock’s Oriole nest. Near the White Rocks Trailhead, eastern birds like Orchard Oriole and Least Flycatcher have sometimes set up shop, alongside southwestern species such as Black-chinned Hummingbird and Bushtit. Please note: dogs are not allowed at the White Rocks Nature Preserve.
Belmar Historic Park
At first glance, this small park may not look like much, but it can be surprisingly birdy and well worth a stop from spring through fall. The trees in the park can attract any number of migrant species; in addition to the common ones, Townsend’s and Virginia’s Warblers and Cassin’s Vireo can all be found during the fall. Kountze Lake, in the middle of the park, often has a variety of waterbirds. Hooded Merganser, Wood Duck, and other uncommon species are usually present. Also look for a variety of heron and egret species as well as breeding American Avocet during the warmer months.
Poudre River Trail and Greeley Gravel Pits
A paved bicycle and walking trail follows the Cache la Poudre River through the northern part of Greeley and westward all the way to Windsor. Some stretches of the river are lined with tall trees; be sure to scan them for nesting Bald Eagles, especially west of town. The trail also runs past many gravel pit ponds that can attract many water birds: ducks, geese, grebes, gulls, terns, and sometimes loons. Access to the best birding is usually at 35th Avenue parking (dirt) area and 71st Avenue parking at Signature Bluffs Natural Area. The Natural area has a very nice boardwalk and soft surface trail that leads into the cottonwoods along the River. If you stay on the paved Poudre Trail about 1/2 mile to the west, you can overlook some ponds to the north that can be quite birdy. There are also a few feeders in private yards along the irrigation canal that the trail follows just across the canal along the way.
The Poudre River Trail is a 21-mile paved pathway extending from Island Grove Regional Park in Greeley to River Bluff Open Space in northwest Windsor, so there are many miles to explore (on foot or bike) for birds and more!
Andrick Ponds State Wildlife Area
Located just to the south and west of the better-known Jackson Lake, Andrick Ponds SWA has huge and largely untapped potential. With abundant marshes, small ponds, and some nice hedgerows, just about any species could show up here. Migration tends to provide the best viewing opportunities, especially during the fall. Wildlife viewing observations are limited to the Saturday of Memorial Day weekend (to coincide with the end of turkey season), through August 31st. Viewing is permitted from the parking lot along County Road 3 and is restricted to Wednesdays, Saturdays, Sundays, and legal holidays only. Hunting occurs at this property so be sure to check for seasonal restrictions before visiting.
Van Bibber Park
Van Bibber Park offers quality habitat for a diversity of wildlife and is a popular stop for migrating birds. The Van Bibber Creek wetlands attract a variety of waterfowl, as well as amphibians and insects. A Scissor-tailed Flycatcher was even once seen in this area. An observation deck on-site makes this a great destination to keep an eye out for visiting birds!
Haxtun Area
The town of Haxtun has numerous large trees that attract birds in migration and at other seasons. One of the best places to bird is the City Park on the northeast corner of town, which has a paved trail underneath mature shade trees. Look for migrant warblers and tanagers in spring and fall, and doves and woodpeckers at other seasons. The wastewater ponds are located just over a mile east of town and are one of the best places in the area to find ducks and geese, mostly in the winter; in spring and fall they can also attract phalaropes and other shorebirds. At any time of year, blackbirds including Great-tailed Grackles may be seen at the feedlot, just north of the sewage ponds.
Sandstone Ranch Community Park
Much of this park contains sports fields, but the portion along the St. Vrain River has been preserved in its natural state as a district park. The 0.7-mile gravel hiking trail crosses native prairie that is home to Lark Sparrow, Say’s Phoebe, and prairie dogs. Native wildflowers such as prickly poppy can bloom here in abundance. The section of the trail near the river, part of which is paved, passes below scenic sandstone bluffs where Great Horned and Barn Owls sometimes roost. The cottonwood forest along the river is a good place to look for House Wren, Warbling Vireo, and Bullock’s Oriole.
The park is on the St. Vrain Greenway, part of the Front Range Trail plan that will someday connect to a larger trail system running from Wyoming to New Mexico. There is a visitor center on-site and open seasonally with restricted hours.
Audubon Center at Chatfield
Just to the south of Chatfield State Park, the trails around the Audubon Nature Center connect with the trails in the park, and are just across the road from Waterton Canyon. Abundant willow scrub habitat here is often full of migrants in season, and it’s a good spot to look for wintering sparrows or a variety of breeding species, including Least Flycatchers. There are also some nice marshes and a small pond with Virginia Rail and Sora, both regular, as well as a nice variety of ducks. Each spring, the Bird Conservancy of the Rockies bands birds at the Center. Check the Denver Audubon and Bird Conservancy websites for information on dates and reservations to visit the banding station.
Two Ponds National Wildlife Refuge
One of the smallest and most urban refuges in the National Wildlife Refuge System, Two Ponds is split up into two parts: the Environmental Education Zone and the Prairie Management Zone. The Environmental Education Zone, which is located east of Croke Canal, is only open May to September. In the Environmental Education Zone, the namesake ponds are too small to have much draw for waterfowl, but they do make the surrounding woodland much more attractive to migrants and breeding species. In this area you will also find a gazebo, amphitheater, shelters and viewing blinds. The Prairie Management Zone, which is located west of Farmers Highline Canal, is open year round from dawn to dusk. The Prairie Management Area is criss-crossed by three irrigation canals which all have mature trees along at least part of their length. There are walking trails with good access along each canal. At both parts of the refuge look for breeders like Warbling Vireo, Western Wood-Pewee, and Cooper’s Hawk. In the prairie areas, Swainson’s Hawk, Loggerhead Shrike, Savannah Sparrow, and others could be found. During migration you never know what might show up! Note that dogs are not allowed at the refuge.
Canyon Journeys
Canyon Journeys Tours offers customized and established tours of some of the heritage sites in Baca County. Please see the tours page to learn more about the tour options. Canyon Journeys Tours is based out of the small town of Pritchett, CO. While the company does not have a store front yet, this is where Canyon Journeys offers tours and lodging for a variety of experiences in southeast Colorado and the surrounding region. Choose from several established tours or customize a tour of your own to visit many sites in Baca County includling Picture, Carrizo, North/Hold, and Cottonwood Canyon and the Santa Fe Trail.
Grant Ranch
This site is a working ranch with extensive shortgrass prairie and playa lakes, hosting all of the regional specialties. Burrowing Owls nest here annually. During spring and fall migration, there is great potential to see huge concentrations of waterfowl and many shorebirds, including Long-billed Curlew. The owner is sometimes available to provide tours, and can regale you with tales about local history and wildlife.
Adobe Creek Reservoir State Wildlife Area (Blue Lake)
This large lake, also known as Adobe Creek Reservoir, is an excellent spot to look for waterbirds and shorebirds of all varieties, especially during migration. Water levels varies wildely, but there is usually some mudflats for shorebirds. There are Least Terns and Piping Plovers nesting here; however, PLEASE do not disturb any nesting areas of these state endangered species. The grassland nearby is quite good, and prairie longspurs and Mountain Plovers should be looked for. Look also for tarantulas, massasauga and prairie rattlesnakes, and other reptiles.
Setchfield State Wildlife Area
This remote site may well be the least visited of all SWAs. It is filled with juniper woodland and rimrock, and and is a good place to see things like Canyon Towhee, Rock Wren, Curve-billed Thrasher, and Ladder-backed Woodpecker, not to mention rattlesnakes and several species of lizard. A small riparian area can be found below the burst dam, and should be checked for migrants in season. Pronghorn and mule deer can be seen in the area.
Lake Meredith
This is the largest body of water in the county. It can attract huge concentrations of waterbirds in migration, and when water levels are low in the fall, many thousands of shorebirds can congregate here. Once a Ruff was seen. The waterbirds stay through the winter, but the north shore is closed from November 1 through the last day of waterfowl season (usually late February). When it is open, it allows primitive camping. Mammals that may be seen here include mule deer, white-tailed deer, coyotes and prairie-dogs.
Cheyenne CR M
This 9-mile stretch of Cheyenne County Road M accesses some nice prairie habitat. All of it is privately owned, so please remain on the road. Look especially for Dickcissel and Mountain Plover and various species of raptors are often seen in this area. Begin at the intersection of US-385 and CR M (4 miles south of Cheyenne Wells), and bird your way west for 9 miles until CR 36.
Holly area
Holly is a charming town that provides good habitat for birds. Gateway Park, on the north side of Highway 50 in town, has many mature deciduous shade trees that can attract migrating warblers and other landbirds. The Holly cemetery northeast of town can also be good for migrants, and sometimes Great Horned Owls can be seen. Three miles east of town is a little rest area along the highway that has a nice combination of trees and brush, where any kind of bird could show up.
Cottonwood Hollow Natural Area
This natural area along the Cache la Poudre River provides wet meadow habitat, which is uncommon in the area and draws a variety of animals. The area contains a few ponds and marshes that can attract ducks, rails, Northern Harrier, and other wetland-loving birds. Other wetland creatures also call this area home, such as Muskrats and Painted Turtles. Please note dogs are not allowed on this property.
Daniels Park
Daniels Park is rich in history as well as habitat for wildlife! The park is part of a larger open space, including 11,000 acres that protect landscapes from Sedalia to Highlands Ranch. Covered in scrub oak, this Denver Mountain Park is a good place to look for Woodhouse’s Scrub-Jay, Bushtit, Virginia’s Warbler, and Rock Wren. Birding is best during the summer, though migration may bring a few other species like MacGillivray’s Warbler, Plumbeous Vireo, and White-crowned Sparrow. A herd of bison roam much of the upper elevations, so there is limited access to most of the park to protect these majestic animals.
Boulder Creek & 75th Street
Located next to Walden Ponds and connected via footpath, the bridge over the creek here is a traditional nesting site for American Dipper, and Eastern Phoebe has also nested here in some recent years. The trees attract spring migrants, including vagrant warblers.
Sandsage State Wildlife Area
This small State Wildlife Area just west of Wray provides access to a stretch of the South Republican River and adjacent grassland. While the riparian habitat along the river here is a bit sparse, check for Orchard Oriole, Indigo Bunting, Brown Thrasher, and more. The more open areas can have Eastern Kingbird, various sparrow species, and Lark Buntings. A visit during migration may produce a surprise, in addition to more normal migrant passerine species, but the wintertime tends to be slow. Hunting occurs on this property, so be sure to check for seasonal restrictions before visiting.
Sloan’s Lake
One of the large lakes in the area, Sloan’s Lake can be a good spot to check fall through spring for ducks of various sorts, the occasional loon (usually Common, but sometimes Pacific) and grebes (this can be a good spot for Horned Grebe). Connected to the wider Denver-area bike trail system, Sloan’s is a great option to hit on a longer trip that includes other areas, such as City Park or the South Platte Greenway.
The Poudre Learning Center
The Poudre Learning Center (PLC) is a premier facility for interdisciplinary learning focusing on the importance of history, science, economics, stewardship and aesthetics of the Cache la Poudre River and Northeastern Colorado. With 65 acres open for the public to explore, the PLC offers easy hiking trails adjacent to the Poudre River, which provides the perfect habitat to attract a diversity of birds and other wildlife. The PLC also offers a variety of nature-based programs and activities for schools and people of all ages! Look for Bald Eagles in the large trees along the river, as well as the usual suite of breeding species during the summer, and migrant sparrows and warblers during the spring and fall. Two smaller ponds can occasionally host small numbers of waterfowl. The Poudre River Trail can also be accessed from the parking lot.
Fort Morgan
If you’re looking for a place to kick back for the night while birding along the I-76 corridor, Fort Morgan has the full range of facilities, as well as good access to nearby first-class birding spots (such as Jackson Lake State Park). For birding in town, check out Riverside Park, which at times can have Snow, Ross’s, and Greater White-fronted Geese during migration and winter, as well as the occasional Harris’s Sparrow among the sparrow flocks during winter.
Welchester Tree Grant Park
The smallest park in the Jefferson County Open Space system, Welchester is home to a historic grove of trees dating back to 1878. Typically, a tiny urban park in the middle of Denver wouldn’t attract much attention among birders, but Welchester Tree Grant Park is different. A plethora of beautifully dense trees, combined with a migrant trap effect mostly likely due to its location, make this one of the better places in the city to hope for uncommon migrants. The list of rare warblers that have shown up here is impressively long, but even without a vagrant, migration here can be good. Look for Townsend’s Warbler and Cassin’s Vireo during the fall months, and Plumbeous Vireo, Wilson’s, Orange-crowned, and MacGillivray’s Warbler both spring and fall. The summers and winters tend to be much quieter.
Frenchman Creek State Wildlife Area
Spring and summer are the best times to visit this mostly dry creek bed, which is lined by sparse cottonwoods, chokecherry, and juniper. East meets west here; both Western and Eastern Kingbirds can be found in summer, and this is a good place to look for Baltimore and Bullock’s Orioles and their hybrids. Hunting occurs on this property, so be sure to check for seasonal restrictions before heading out.
Union Reservoir Nature Area
This large reservoir is one of the best places in the area to look for ducks, grebes, loons, and other waterbirds from fall through spring. Many rarities have shown up here, including Red-throated and Yellow-billed Loons, Ancient Murrelet, Hudsonian Godwit, and Little Gull. The reservoir is usually frozen in January and February; Clark’s and Western Grebes are reliable the other ten months of the year. The reservoir can be scanned fairly well from CR 26 on the south or from CR 28 on the north. A Longmont City Park on the southwest corner offers camping, picnic areas, and swimming in the summer. Fees apply in the city park – be sure to contact City of Longmont or visit their website for details.
Chatfield State Park
Most birders in the Denver area will tell you Chatfield reigns supreme among the metro-area reservoirs. This state park is a contender for the most birds observed at any single location in Colorado. With miles of walking trails, good lakeside access, and abundant facilities, it would be easy to spend an entire day at the park, any time of the year.
Most species of waterfowl and shorebirds that occur in Colorado can be found at Chatfield. The Swim Beach on the western side of the lake, the sandspit/marina areas on the eastern side, and the Lake View parking area on the southern end are the park’s bird-viewing hotspots. Loons and diving ducks are commonly observed near the dam, while the southern end of the reservoir usually has more dabbling ducks. In winter, open water holes can attract high concentrations of birds. Winter is also the best time to look for flocks of gulls. When the water level is low, the Plum Creek Delta and the sandspit near the marina are excellent viewpoints for shorebirds.
The trails along the South Platte River and Plum Creek are shaded by cottonwood trees that provide habitat for a number of breeding species. These areas are among the few places in the state where Least Flycatcher and American Redstart breed. Other interesting species to look for in these riparian areas include Yellow-billed Cuckoo, Indigo Bunting, American Dipper, and Eastern Screech-Owl. The open prairie areas of the park offer opportunities to observe shrikes, Vesper Sparrow, flocks of Horned Lark, and the occasional longspur. A State Parks pass is required for entry.
Standley Lake Regional Park
The largest body of water in the northwestern metro area, Standley Lake ranks high among the great Denver area lakes for birding opportunities. The lake tends to be most productive during the fall months when large numbers of waterfowl, loons, grebes, and gulls pass through, but it remains good as long as there is open water. In early spring, gull variety often increases and waterfowl numbers pick up again as they move north. The summer months tend to be fairly quiet, though the remnant open prairie habitat can have a few breeding species, while the small tree groves play host to birds such as Spotted Towhee, Bullock’s Oriole, and Lazuli Bunting, and in recent years, a nesting pair of Bald Eagles. Be sure to check out Standley Lake’s live Eagle Cam.
Picture Canyon
Like most of the southeast’s remote canyons, Picture Canyon has abundant pinyon-juniper woodland and rimrock/cliff habitat. In addition to those, there are some excellent permanent springs, with some associated riparian growth, and some high-quality yucca grassland. A nice system of trails allows access to all these habitats, and a wide array of great scenery. Look for Rufous-crowned and Cassin’s Sparrows, Eastern Phoebe, and Long-billed Curlew (on the drive in) and wild turkeys; the rimrock has a few owl nests in the rock and harbors rattlesnakes, and some of the semi-permanent pools along the intermittent streams are home to the striking black-and-yellow tiger salamander.
Yuma
Yuma is a fairly large plains town and has lots of mature deciduous trees for birders (and birds) to choose from. City Park in the north part of town might be a good place to start – it has a few large trees that shade a good-sized duck pond. Northeast of town, the Yuma cemetery has medium-sparse vegetation, but its isolation may help it concentrate migrants better than the town. South of the cemetery is one of the nicest sets of sewage ponds on the Eastern Plains – not to be missed by anyone traveling the US 34 corridor.
Comanche Creek Road (CR 61-69)
This road north of CO 86 parallels its namesake for several miles, and although the lowland riparian habitat is private, it is in several places close enough to the road to be easily birdable. If you head east on CR 150 for 0.7 miles, you’ll come down off some bluffs through a belt of ponderosa forest. This area has the likes of Cassin’s Kingbird, Spotted Towhee and Black-headed Grosbeak.
Flagler Reservoir State Wildlife Area
Because this is one of the only reservoirs in the area, the water and large trees here act as an excellent migrant trap. The best trees are below the dam and along the inlet stream to the south. The lake itself can be good for all kinds of ducks, and when low, for shorebirds. Wild Turkeys can usually be found just below the dam. The grassland to the east is of fairly high quality. Look also for deer, pronghorn, rattlesnakes and Regal Fritillary (a magnificent and rare butterfly). Note that hunting is very popular here in fall.
Las Animas
This large town is an excellent place to base yourself out of on a trip to SE Colorado. It is centrally located to a number of excellent birding spots. In and around town itself, check the cemetery on CO 101 just south of town, which has lots of big trees, and the river crossing over the Purgatoire River on CO 101. At this spot and elsewhere along 101, look for Chihuahuan Raven and Greater Roadrunner.
Wilson Ranch
Approximately 20 miles south of the town of Las Animas, the Wilson Ranch hosts vast areas of shortgrass prairie and numerous canyons for exploration. The prairie is home to many species including Burrowing Owl, Cassin’s Sparrow and Long-billed Curlew and is known to have high concentrations of Mountain Plover in mid to late summer. The scenic canyons are an added bonus to the ranch that take most visitors by surprise, as the drive south from Las Animas does not hint at the changing topography. The juniper-lined canyons are a great place to explore and look for cliff-dwelling raptors such as Golden Eagle, Red-tailed Hawk, Great Horned Owl and American Kestrel. The intermittent streams running through the canyons support pools of water and willow/cottonwood groves that make great stopover areas for migrants. The ranch also offers a number of old homesteads and rock houses to explore. The Wilson Ranch is managed for healthy range and riparian areas and the abundance of wildlife present is a result of the family’s commitment to conservation. It is a working ranch that offers guided and self-guided tours, horseback riding, hiking and biking as well as lodging and meals upon prior arrangement. For more information and directions to the ranch, call Max and Vanessa Wilson at (719) 456-1051 or email maxgwilson@gmail.com.
Ordway
This is the population center of Crowley County, and it has restaurants, gas and groceries. Conestoga Park in town hosts breeding Mississippi Kites in summer. Ordway Reservoir State Wildlife area, just north of town, has a pond worth checking for waterbirds, however access is only available from September 1 through the end of February.
Cheyenne CR 40
The first 3 miles of County Road 40 south of County Road G is dryland farm ground. There is some nice remnant of shortgrass prairie 2 miles south of the intersection of County Road 40 and County Road C for about 2 miles, then it returns to dryland farm ground. Burrowing Owl, Long-billed Curlew and Grasshopper Sparrow all breed here, but the land ownership is private, so please stay on the roads.
Taylor Ranch
This working ranch boasts a suite of attractions for travelers. The unique landscape hosts many of our native prairie birds such as Mountain Plover, Scaled Quail and Cassin’s Kingbird. The ranch also boasts a high concentration of raptors including Northern Harrier, Swainson’s Hawk, as well as nesting Golden Eagles and Ferruginous Hawk. Migrants have included Sandhill Cranes, Lark Buntings and Mountain Bluebirds. Arroyos, natural springs, and frontage along North Butte Creek make this a beautiful site to hike. A variety of reptiles such as collared lizards, blackcap snake, three species of horned lizards, possible leopard frogs and hog nosed snakes have been seen on the property. The owners can impart a great deal of the area’s lore, including knowledge of a site on the property where a hanging took place and are willing to give guided tours. Pronghorn, white tailed and mule deer, a variety of foxes and coyote frequent the ranch. The ranch’s livestock include rare British White cattle and Haflingers horses.
Fort Collins City Park/ Grandview Cemetery
Grandview Cemetery, which borders Fort Collins City Park, is a wonderful place to walk underneath a canopy of mature deciduous and evergreen trees. The cemetery is also a Certified Audubon Cooperative Sanctuary through the International Audubon Cooperative Sanctuary Program (ACSP). Look for a popular pair of Great Horned Owls that nest here in most years, and keep your eye on the evergreens, which can attract Brown Creeper, Golden-crowned Kinglet, Pine Siskin, and occasionally crossbill in winter. Rare migrants sometimes show up – most famously Colorado’s only Tropical Parula in the summer of 2005! Sheldon Lake, in the City Park, hosts waterfowl in winter.
Jarre Canyon Road and Platte River Road
Jarre Canyon Road (CO 67) passes through patches of scrub oak and horse pastures before climbing into the foothills ponderosa pine habitat. A few pull-offs, mostly on the right (north), provide possible places to explore for ponderosa birds year-round, such as Hairy Woodpecker, Mountain Chickadee, Pygmy and Red-breasted Nuthatch, and Red Crossbill; in summer, look for Western Wood-Pewee, Plumbeous Vireo, House Wren, Western Bluebird, and Western Tanager. At Sprucewood (right), the West Pine Creek Road plunges directly down to the South Platte. Otherwise, continue on CO 67 to the river, where a few stream-tied species occur. In addition to birding, there are plenty of other recreational activities here ( such as fly fishing, tubing, swimming, and picnicking), making this a good place to spend the day with family and friends.
Walden Ponds Wildlife Habitat and Sawhill Ponds
Walden and Sawhill Ponds are some of the most important birding areas in Boulder. Between fall and spring, over two dozen ponds make this one of the best places in the area to look for dabbling and diving ducks, shorebirds, and the occasional vagrant, such as swans. March is the best month to catch migrating ducks. In summer, Wood Ducks nest along Boulder Creek, along with the occasional Eastern Screech-Owl; Bank Swallows flit overhead and Eastern Kingbirds twitter angrily. You might also view the Osprey nest, cormorants, bitterns, and a heron rookery. Near the parking lot for Walden Ponds, a boardwalk across Cottonwood Marsh provides up-close looks at Tree Swallows in nest boxes, and Red-winged Blackbirds on territory. Watch for garter snakes, frogs, and other critters along the edges of the ponds.
Berkeley Lake and Rocky Mountain Lake
These two lakes are nearly adjacent and nearly identical. Both are medium-sized lakes ringed by promising lines of cattails, and surrounded by walking trails. Look for breeding coots and Pied-billed Grebes in summer, and for Western Grebe and numerous species of waterfowl in migration and winter. Also be sure to check the woodland in both parks for migrants during the spring and fall, and flocks of sparrows and Cedar Waxwings during the winter months.
Windsor Lake/Boardwalk Community Park
Often confused with Windsor Reservoir, which is three miles north, Windsor Lake is right in the town of Windsor. At times it attracts huge numbers of ducks, gulls, and grebes. The lake is easy to view from the west dedicated parking area along North 7th St. (Hwy 257) or from Boardwalk Community Park, and a nice walking/biking trail runs all the way around it. There is also a small parking area on the southeast corner of the lake.
Jean K. Tool State Wildlife Area
With access to the South Platte River and its associated dense and extensive riparian corridor, this SWA is a good place to look for local and uncommon breeders such as Yellow-billed Cuckoo, Red-bellied Woodpecker, and Bell’s Vireo, as well as migrants in season. During winter months, it tends to be a lot quieter, but check for sparrow flocks and Northern Shrike. Wild Turkey and Northern Bobwhite are possible all year. Hunting occurs on this property, so be sure to check for seasonal restrictions before visiting.
Golden
Famous for its breweries, the Colorado School of Mines, and its beautiful location, Golden is a town worth visiting for non-birding reasons alone. If you want to bird the northwestern metro area or nearby foothills, it also makes a good base offering all the typical amenities. For the ambitious, it’s possible to bike from Golden to the larger Denver-area bike trail system, allowing for a full day out while avoiding using a motor vehicle.
To the east along 10th Street, which winds past the Coors headquarters and becomes Denver’s 44th Avenue, is the Crusher Fire Trail, which follows the Church Ditch along the west side of Tony Grampsas Memorial Sports Complex. The trail is nicely wooded for most of its 1.3 mile length. Access is via a small trailhead on Easley road about half a mile north of 44th or by walking west from the parking lot in Tony Grampsas park. You can also get to this area by heading east along the bike trail that follows Clear Creek. The tree-filled School of Mines campus is sometimes worth a leisurely walk as well. You may want to check out Jefferson County Open Space’s website if you’d like to stop at one of the numerous parks they manage in this area.
Sand Hills
The southern portion of Phillips County has some sandsage habitat where Cassin’s and Lark Sparrows breed, along with Colorado’s state bird, the Lark Bunting. Small numbers of Greater Prairie-Chickens are also present, but unlikely to be seen. Along County Road 2 west of County Road 35, there is a seasonal playa that can attract ducks and shorebirds when it has water. Look out for pronghorn, as they are easy to find in the area.
Jim Hamm Nature Area
This small park near Union Reservoir can quickly be checked for birds. Sometimes there is little of interest, but sometimes, gulls or shorebirds from Union stop in here, allowing a closer look. As a designated bird sanctuary, the pond is the main attraction, but the line of trees north of it might also be worth checking for birds.
Robert F. Clement Park
The main attraction at this park is the large Johnson Lake, good for waterfowl of various species (including Canvasback, Bufflehead, Hooded Merganser, and Common Goldeneye), as well as Eared Grebe and the occasional loon. There are quite a few trees in the area as well, though the lack of undergrowth cuts into the variety of birds that could show up. Still, they are worth a look especially during migration.
Stearns Lake
Stearns Lake attracts waterfowl between fall and spring, sometimes including geese by the thousands. Savannah Sparrows forage along the shoreline in fall. Large trees in the vicinity are likely to feature Swainson’s Hawks in summer and Bald Eagles in winter. Follow Rock Creek Trail for access to the surrounding fields, home to meadowlarks and a few Ring-necked Pheasants, which are very local in the area. Coyotes are also regularly seen here. Some trails may be closed seasonally to protect nesting Bald Eagles.
Campo
Campo is the gateway to the Lesser Prairie-Chicken lek located on the Comanche Grasslands east of town, as well as to the well-known Picture Canyon and Carrizo and Cottonwood Canyons located at the foot of the Mesa de Maya west of town. This is a tiny town with few trees, but it is so isolated that significant migrants can be found here. Stop to have breakfast at the Campo Cafe and look for warblers and vireos in spring. A nice area with picnic tables and mature trees is located on the grounds of the town community center where you may see owls in the trees.
**NOTE: CPW will not disclose any lek locations due to the severe decrease in lesser prairie chicken populations. Restoration efforts are in place, however viewing opportunities are restricted in order to protect what numbers we do have.
Otis
Small and isolated, this prairie town has a few mature deciduous trees. The cemetery south of town contains some good juniper hedgerows worth a quick look in winter or migration. Just east of town is the town’s sole sewage pond, which is small but can attract various waterfowl, ibis, and who knows what else!
Mi Tierra
Experience the tranquility and solitude of a ranch located on the high plains with a clear view of the entire Rocky Mountain front range. This working ranch is nestled in towering Ponderosa Pines on a high ridge located approximately 15 miles northeast of Kiowa. This pristine area is a great setting for artists and writers as well as those of us who thrill at the sight of wildlife, a star-filled sky, or the dying embers of the evening campfire. Birdlife is likely to include breeding Cassin’s Kingbird, Black-headed Grosbeak, Western Tanager, Lazuli Bunting and many prairie birds. Multiple lodging options are available at Mi Tierra including tent camping, bed and breakfast accommodations, and a unique rustic yurt for an economical and unusual getaway.
Crystal Springs Ranch
This working ranch borders Flagler State Wildlife Area to the north. With a flowing natural spring and two ponds, it is a lovely spot for viewing all kinds of wildlife. Rails can be found in some of the wetter areas, and the trees on the property are worth birding at any season. In addition, your opportunities for finding prairie birds are much better on this property than at the State Wildlife Area to the south. This is a destination along I-70 that no birder should miss!
Fort Lyon State Wildlife Area
This wildlife area is a westward continuation of the marsh at Fort Lyon. If you could not find Black Rail at John Martin, then this is another place where they occur. All of the species listed for the marsh at Fort Lyon have been seen or heard here. The thickets along the entrance road are worth a look for sparrows and other passerines. If you are driving the roads at night, keep an eye out for opossums; this is one of the best areas in the state to see this southern mammal. Be aware hunters may be present during hunting seasons.
Walter Ranch
This working private farm/ranch contains several thousand acres of beautiful scenery in the canyon country of the Comanche grasslands. It is recommended to obtain permission to access this ranch prior to driving or hiking on this property. Hike through barely explored areas that host a diverse array of both grassland and shrubland birds. The canyonlands are home to many nesting raptors, including Golden Eagle and Prairie Falcon. This area is rich with Native American and Wild West lore, and the owners enjoy talking with visitors about that history.
Cholla stands in western Crowley County
Western Crowley County contains one of Colorado’s best examples of the semidesert shrubland habitat, which is dominated by the spiny cholla tree cactus, a plant that looks like it belongs in Southern Arizona. And maybe it does–because in the cholla occur birds more commonly associated with Arizona than Colorado: Scaled Quail, Curve-billed Thrasher, and if you’re lucky, Greater Roadrunner. A few Mountain Plover breed in this area too, just to remind you you’re in Colorado. Jackrabbits and Pronghorns are plentiful in this area. Viewing from vehicle only, private property on both sides of the road.
Nee Gronde Reservoir (Queens State Wildlife Area)
This is large reservoir that can be quite productive, especially in winter, when huge flocks of geese and large numbers of Bald Eagles can congregate here. A trail leads down to a viewing blind at Mud Lake to the northeast with interpretive signage. Other wildlife in the area include pronghorn, white-tailed deer, rabbits, foxes, and snakes and other reptiles.
Two Buttes Reservoir State Wildlife Area
This reservoir and state wildlife area just east of Highway 385 and south of the Prowers county line is among the crown jewels of Southeast Colorado birding spots. Above the dam is a middle-sized reservoir lined with cottonwoods and rimrock, which can be good for ducks and grebes when high and for shorebirds when low. Below the dam is a veritable wonderland of habitats, including extensive tangles of underbrush, tall trees, marshy ponds and grassy areas. This area can be excellent any time of year, but especially during migration; it is probably the best public area in Colorado to find roadrunners. Check for roosting Barn and Great Horned Owls along the cliffs. The vagrant list for this area is truly impressive. Look along the entrance road to the north for Mountain Plovers in season, and prairie longspurs in migration. In the prairie dog towns you will find Burrowing Owls and perhaps a Swift Fox. Various species of reptiles and amphibians live here, including prairie rattlesnake, plains spadefoot and red-spotted toads, painted and ornate box turtles, and fence lizards. Pronghorn, raccoons and coyotes can be seen as well. Insect repellent can be a good idea during the warmer months.
Pineridge Natural Area/Dixon Reservoir
The dense tangle of deciduous trees at the north end of Dixon Reservoir, in the Pineridge Natural Area, is well-known among birders as one of the best migrant traps in Fort Collins. May is the best month to find migrant warblers, sparrows, flycatchers, and orioles in the trees. The narrow paths cutting through the trees are often flooded in spring, but a higher, drier dirt path encircles the area, providing some viewing opportunities when the water is high.
Devil’s Head
The 1.4 mile trail up Devil’s Head (9,748 feet), which leaves from CO 67, is restricted to foot traffic, and passes through ponderosa, Douglas-fir and aspen zones, with a chance for birds more typical of the higher mountains. Spectacular views over the plains temper the climb to the lookout. Look year-round for Steller’s Jay, Clark’s Nutcracker, Common Raven, both chickadees, and all three nuthatches; in summer look for Olive-sided Flycatcher, Plumbeous and Warbling vireos, Ruby-crowned Kinglet, Audubon’s Warbler, Western Tanager, and more.
Teller Lake #5
This lake sits amidst farmland utilized for livestock grazing, crop production, and even beekeeping! The water sometimes attracts interesting waterbirds and Dickcissel has at times bred in the fields to the south. Lark Bunting and Blue Grosbeak have also been spotted here. The nearby black-tailed prairie-dog colonies are sure to attract raptors and other predators. Please note dogs are not allowed at this property.
Heron Pond/Heller Open Space
Close to downtown, this small lake ringed with trees is in the middle of an urban open space, but can attract surprising birds. Look for ducks in the colder months, and in migration, hope for a wandering prairie bird like a Loggerhead Shrike or a Lark Bunting; they aren’t normally found in the city, but occasionally stop here due to the open habitat. This natural area is connected by trails to the adjacent Northside Park and the bike path along the South Platte River.
Windsor Reservoir
Often confused with Windsor Lake, which is three miles south in the town of Windsor, Windsor Reservoir is larger and often attracts more birds. It is a particularly good place to find diving ducks and flocks of gulls. However, it is a private lake relatively far from the road, so it can be difficult to view; a scope is required. The best spot to scan from is the end of the dam, near the busy intersection of CR 74 and CR 19. Be cautious of traffic when parking and walking.
Brush Prairie Ponds State Wildlife Area
This section of prairie habitat is sometimes flooded, primarily in early summer, and attracts ducks and shorebirds during such times. At other times, check for Lark Bunting, Brewer’s Sparrow, Lapland Longspur and Horned Lark (during the winter months), and raptors of various stripes at all times of year. Wildlife viewing and birding is open only from March 1 through August 31 in specific areas as posted. Hunting occurs on this property, so be sure to check for seasonal restrictions before visiting.
Arvada Blunn Reservoir
This large reservoir, while not as productive as other Denver area lakes, can often have good numbers of waterfowl and the odd loon in the fall and spring. Barrow’s Goldeneye sometimes show up in November, and a variety of gulls are possible in the colder months. There are also some decent riparian thickets and groves along the walking trail on the western edge of the reservoir that should be checked during migration.
Holyoke
The largest town in Phillips County, Holyoke is a good place to see Mississippi Kites in summer. Look for them in the air, or anywhere above town, as they pursue flying insects on the wing. You might find their nests in the large shade trees around town, which also attract migrant warblers in spring. Southeast of town is the Holyoke Cemetery, which can be worth a visit during spring for migrants, and you might spot burrowing Thirteen-lined Ground Squirrels. Just east of town is the Lions Club Fishing Hole, a small pond with a boardwalk and viewing platform that can have ducks at any season and migrants in spring. Bell’s Vireo can sometimes be found in summer in the thick vegetation east of the pond.
Little Gaynor Lake
The nature preserve that contains this small prairie pothole lake is often worth a check. Scanning from the blind on the north shore can turn up a good variety of ducks, often including Cinnamon Teal, Northern Shoveler, and Ruddy Duck, plus American Avocets and Wilson’s Phalaropes.
Marston Lake
While not quite the same caliber as Chatfield or Cherry Creek Reservoirs, Marston is still one of the best lakes in the Denver area. Productive at almost any time of year (perhaps least interesting in the middle of the summer), the lake can have almost any of the waterfowl species that occur in the state. It is semi-reliable for Barrow’s Goldeneye during the late fall and winter, and is among the best spots in the area for loons (including Pacific) and all the regular grebe species. When an ice shelf forms, there can sometimes be large flocks of gulls; look especially for Thayer’s and Lesser Black-backed Gulls from late fall through early spring. The property is private, and can only be viewed through a chain-link fence.
McKay Lake
This small lake and associated riparian grove near Broomfield make for a pleasant stop if in the area. Look for a variety of waterfowl (best during the spring and fall; winter if there is still open water), and passerine migrants during appropriate times of year. In the late fall or early spring when ice is on the reservoir, this can also be a good place to look for gulls.
Akron
The county seat and largest town in Washington County, Akron has some decent large trees worth checking in migration. It also has more amenities than most of the other small towns in the area.
Kiowa area
Kiowa is a rather charming town that can have wandering mountain birds in winter and migrants in spring and fall. It is also a good place to get food or other essentials. Check out hummingbird feeders around town in season. The road from Kiowa north to Bennett runs through some nice yucca habitat with breeding Cassin’s Sparrows.
Hickman Farm
This property consists of mixed-grass prairie and cultivated land with scattered tree plantings and draws. Watch for red and swift fox in the open prairie as well as mule and white-tailed deer and badger. Pheasants can also be observed in the area, along with Colorado’s state bird, the Lark Bunting. You can also see Mountain Plover, Northern Harrier, Grasshopper Sparrow, Cassin’s Sparrow and possibly Short-eared Owl. Playas are also present throughout the area and when wet harbor Long-billed Curlew and other shorebird species. Pronghorn are also common. Sunflowers paint the roadsides with color in the summer; in fall, longspurs and possibly Sprague’s Pipits migrate through the property. Take the time to hike through the mixed grass prairie and explore this beautiful country. Cultural artifacts have also been observed on site including arrowheads and Native American beads. Site offers guided and self-guided tours, hunting, stargazing, and cultural attractions.
Fort Lyon area
Starting just east of the tiny town of Fort Lyon is the enormous Fort Lyon Wildlife Easement, a large tract of lowland riparian habitat. This is an exceptionally good spot for migrant, and Barn and Western Screech-Owls breed here. Starting at the corner of CRs HH and 16 are the John Martin Marshes, an amazingly large area of cattails spreading from here at least a couple of miles to the east, and measuring a couple of miles wide in some places. The most famous resident of this marsh is Black Rail, of which one can often hear 15 or 20 along CR 16 on a night in May. Other species usually heard at the marsh include Marsh Wren, Virginia Rail, Sora, and American Bittern. Finally, along CR JJ east of CR 16 there are some more cattail marshes, with the same residents.
Picket Wire Canyon
You can access Picket Wire Canyon through Withers Canyon Trailhead on the Comanche National Grasslands. Foot and bike access are allowed, and this wide canyon has permanent water. The hillsides here are dominated by pinyon-juniper, the valley bottoms by saltbush, and the riverside by sparse but large cottonwoods. From the parking lot, it is a mile to the river down a steep, rough, road. From there, it is a mile and a half south to the Las Animas County line, and five miles to the dinosaur tracks that many people come here to see. Ornithologically, Picket Wire Canyon is good for such SE specialties as Ladder-backed Woodpecker, Curve-billed Thrasher, Scaled Quail, Rufous-crowned Sparrow, and Cassin’s Kingbird, among many other possibilities. Mammals here include elk and deer. There is also mountain lion, bear and bobcat, although your chances of encountering any of these is very slim. Be aware summer experiences extreme heat in this area, so be prepared.
Olney Springs Reservoir
The small town of Olney Springs has a little reservoir with some good trees, especially on the other side of the canal. The reservoir is currently dry as they are working on the reservoir. Check the trees for sparrows in the colder months, and for flocks of migrants in spring and fall. Mammals that might be seen in the vicinity include mule and white-tailed deer, rabbits, red fox and coyotes. If the road is gated, you may enter on foot.
Nee So Pah Reservoir (Queens State Wildlife Area)
The westernmost of this group of reservoirs. Depending on water levels, it can be good for waterbirds, shorebirds, or gulls. The grassland along the road on the western side of the reservoir is quite good, and in season you may see Horned Larks, longspurs, Mountain Plovers, coyotes, jackrabbits and deer here. There are no trails to access this site. Bring a scope to scan the reservoir from the road. This reservoir was empty in 2021.
Turk’s Pond State Wildlife Area
Check this small pond for ducks during the fall and spring, and shorebirds if the water is low. The few small trees around the lake could contain migrants in season, and sparrows during the winter. The small pond across from the entrance road often has as many ducks as Turk’s Pond does. Other wildlife here can include white-tailed deer, rabbits, foxes, raccoons, reptiles and amphibians. Please note this SWA is closed from the start of goose season to the end of season.
Horsetooth Reservoir
Horsetooth Reservoir is a deep, steep-sided foothills lake very similar to Loveland’s Carter Lake. In winter, it freezes late and can attract Bald Eagles, gulls, and ducks, including the uncommon Barrow’s Goldeneye. Pine and mountain mahogany woodlands surround the lake, providing breeding sites for Western Tanagers and Townsend’s Solitaires. This reservoir is one of the best places close to Fort Collins to see foothills animals such as the golden-mantled ground squirrel and the pine squirrel. This area is extremely busy, particularly on weekends and in the summer, so get there early! An entrance fee is required for most areas around the lake.
FR 550
This remote dirt road (which can be rough at times, especially after the spring snowmelt), provides good access to montane forest habitats. The pine forests should have the typical specialty species including Williamson’s Sapsucker, while higher up American Three-toed Woodpecker can be found, with luck. The Tramway Trail, 4.5 miles east of Pine Valley Road, accesses some burned habitat, which offers more chances for spotting woodpeckers.
Erie Lake and Thomas Reservoir
These small lakes are best known as places to find gulls in the colder months, when the water is partly frozen. They can also attract ducks and other waterbirds, and rarities have been found in the area; Erie Reservoir even once boasted a Yellow-billed Loon.
City Park
Denver’s large and impressive City Park is more than just a park – it is also home to the Denver Zoo and the Denver Museum of Nature and Science, both well worth a visit in their own right. The park itself is a cornucopia of beautiful trees and several productive ponds. The best birding tends to be along the nature trail around Duck Pond, where breeding colonies of Black-crowned Night-Heron, Double-crested Cormorant, and Snowy Egret are occupied during the spring and summer, and the abundant trees can have migrants in season. City Park Lake is also worth a check for a variety of waterfowl, including often tame Wood Ducks. During winter, flocks of sparrows and sometimes finches can be found, and the park, not surprisingly, is also a good place to look for the typical suite of urban birds. Note: although the park is open daily from 5 AM to 11 PM, the gates allowing cars to enter are closed on Sundays (May through September), and occasionally during special events.
Black Hollow Reservoir
This large reservoir is rather far from the road, so a scope is required for good viewing of birds. Between late fall and spring, the main attraction here is usually the large flock of gulls resting from their feeding forays from the nearby Weld County Landfill. Rare gulls like Lesser Black-backed and Thayer’s are regularly part of the flock. In recent years, a pair of Bald Eagles has nested at the reservoir on the north side.
Brush State Wildlife Area
The extensive riparian habitat along the South Platte River corridor makes for excellent birding, and can be acessed at several points in the area. Perhaps the best is at Brush SWA, where trails bring you through cottonwood gallery forest and past several wetlands. This is among the best places in the state to find Northern Bobwhite, which are increasingly difficult to come across, and Wild Turkey is regularly encountered. During spring and fall migration, a variety of warblers and other migrants can be found here, and rarities have shown up. During the later fall and winter, the birding tends to be quieter, but it can be a good time for sparrow flocks. Eastern Screech-Owl is fairly common in the area; a visit at dawn or dusk may well turn one up. Keep an eye out for White-tailed Deer and a variety of plains butterfly species. Hunting occurs on this property, so be sure to check for seasonal restrictions before visiting.
White Ranch Park
One of the larger open space parks in the area, White Ranch has two different entrances that provide access to different montane habitats. The eastern entrance has abundant foothill scrub and some riparian woodland; look for Bushtit, Western Scrub-Jay, Green-tailed Towhee, and others in the scrub; in the riparian habitats, you can find Yellow-breasted Chat, Cordilleran Flycatcher, and Lazuli Bunting. The western entrance provides an area of ponderosa woodland and montane meadows; in this section search for Williamson’s Sapsucker, Pygmy Nuthatch, both Western and Mountain Bluebirds, and the occasional Dusky Grouse. The whole area is popular with mountain bikers and hikers, and if either of these activities is your cup of tea, White Ranch is a good place to combine them with some birding.
Sand Draw State Wildlife Area
This spot is an oasis of tall trees and dense undergrowth that provides a haven for deer, cottontail rabbits, and various bird species. Listen for the scratchy warbles of Bell’s Vireo in summer, along with the complex song of the Brown Thrasher. The denser pines may harbor roosting owls, especially in winter. A network of wide paths provides foot access to the area from the parking lot, though these paths can become overgrown in summer. Hunting occurs on this property, so be sure to check for seasonal restrictions before heading out.
Dodd Reservoir
Birders’ attraction to Dodd Reservoir can be summed up in one word: geese. From fall through spring, this is one of the most reliable places in the area to find thousands of geese. Most are Canadas, but a fair number of Cackling Geese are typically mixed in, and usually one or two Snow, Ross’s, or Greater White-fronted Geese are found here as well. The geese spread out during the day to feed in the surrounding fields, but when they all crowd back onto Dodd Reservoir, it can be quite a sight to behold! Please be aware pets are not allowed at this property.
Centennial Park
The medium-sized pond here is probably the best pond for waterbirds in the area. Large flocks of dabblers and divers can be found here during the colder months, and keep an eye out for grebes and maybe even the stray loon or two. Gull flocks could potentially hold an interesting species or two during the winter, and the thickets often have flocks of sparrows and sometimes Cedar Waxwings.
Eastlake #3 Park and Nature Preserve
This lake may be small, but the bird numbers here often aren’t! The full suite of waterbirds could be found here (at least when the water isn’t frozen). Look especially for species like Hooded Merganser and Cinnamon and Blue-winged Teals. The surrounding cattail marshes can have Virginia Rail and Sora on occasion, as well as Marsh Wren, and the riparian habitat may be good for migrants in season.
Comanche Grasslands
Colorado’s ‘other’ grasslands are much less visited by birders than the Pawnee, but can actually be better, especially for hawks. Most of the grasslands have a high percentage of yucca, unlike grasslands further north. Driving the roads through the grasslands, especially during the winter and early spring, will produce an excellent variety of hawks, including Ferruginous (possibly more numerous here than anywhere else in Colorado). During March and April, McCown’s and Chestnut-collared Longspurs are possible, and sometimes they even winter in the area. Mountain Plover can be found in areas with very short grass, as well as Burrowing Owls. Long-billed Curlews breed in larger, less disturbed pastures. Many rare mammals could also be seen, including Badger and Swift Fox.
Longspur and Plover areas in Washington County
Typically Chestnut-collared Longspur breed on private land in Washington County on Road KK between Road 19 and Road 20. McCown’s Longspur and Mountain Plover have also been seen in this vicinity, and pronghorn and jackrabbit are very common; even badgers may be seen. When looking for wildlife, you need to stay on the public road.
Elizabeth
Drive around this quaint little town looking for busy feeders, and while you’re at it, keep an eye out for the Eurasian Collared-Doves that have recently colonized it. The cemetery on the south side of CO 86 in the middle of town is worth checking for conifer-loving birds as well as migrants. The city park also has some large trees worth a look.
Loutzenhiser Farms
This is a chance to view a working farm with several playas that offer migratory shorebird viewing. In Kit Carson County, where water is often rare, this is a must-hit spot when the playa is full, as the concentrations of shorebirds can be impressively dense. Mountain Plovers have been seen using these farm fields as a staging ground just prior to migration.
John Martin Reservoir State Park
The largest reservoir in SE Colorado. This state park has something to offer everyone, with shorebirds and waterbirds on the reservoir itself, passerines in the large riparian area below the dam, and grassland species on the grasslands just south of the park. A blind overlooks the Santa Fe Trail slough just west of the Visitor Center. To scan the reservoir, walk out along the dam road, or scan from the overlooks on the north side near the visitor’s center. The south shore, which is state wildlife area, can be scanned year round, but during the summer portions may be closed to protect Piping Plovers and Least Terns. Below the dam, the Lake Hasty Campground has an excellent riparian area, and Lake Hasty can be good as well. The thickets along the outlet are worth a look. Just south of the reservoir are some excellent yucca grasslands with Cassin’s Sparrows and Ferruginous Hawks, among others. Deer and rabbits can be common in the area. Please stay on established roads. In February the reservoir hosts the High Plains Snow Goose Festival and in May they host the Bent on Birding festival. Contact the reservoir at 719-829-1801 for more information.
Otero CR E
The small area of saltbush and sagebrush flats here support one of the only SE populations of Black-throated Sparrow. Both Brewer’s and Cassin’s Sparrows could also be seen, along with coyotes and jackrabbits. Checking the small riparian corridor from the bridge over the Purgatoire River may also be productive.
Rocky Ford
This large town is an excellent birding location, with many large trees that often contain some interesting species. The gem of this area, though, is the Rocky Ford State Wildlife Area, with its excellent riparian habitat, thickets and river access. Look here for sparrows, migrants, Western Screech-Owl, squirrels, muskrat and deer. A short viewing trail is located on the McClelland Tract of the SWA which leads from a parking area along the top of the rolling hills above the Arkansas river to an overlook with a sandstone bench. In addition to the SWA, the sewage ponds just northeast of Rocky Ford can be great for shorebirds and waterbirds, depending on water levels. Dickcissels nest near here.
Nee Noshee Reservoir (Queens State Wildlife Area)
Nee Noshee Reservoir is the largest of these reservoirs. When the water level is low this can be a great location for shorebirds, and waterbird numbers are often quite good as well. The weedy brush along the south shore is quite good for sparrows, and sometimes Long-eared Owls. The grove on the western side of the lake, known as the ‘Locust Grove,’ is smaller than it once was but may still yield migrants. To reach Locust Grove, turn left just before the bathroom structure and parking lot and follow the gravel road to the west around as it swings around the southwest corner of the lake. Park where the northbound road is approached most closely by a grove of locusts and brush pushing west from the cottonwoods along the lakeshore. This is the Locust Grove. To scan the water of Nee Noshee, drive to the southern parking lot, and then drive north ‘into’ the reservoir, until you reach the water. In recent years this requires a drive of a mile or more.
Horsetooth Mountain Open Space
This large open space has 29 miles of rugged trails through shrubby slopes and open Ponderosa woodlands. One might see Bullock’s Oriole near the parking lot and Mountain Bluebird higher up. Keep an eye out for White-throated Swifts and raptors in the sky overhead. Mountain Lions roam here, though it requires tremendous luck to see one. This area is extremely busy, particularly on weekends and in the summer, so get there early!
Pine Valley Ranch Park
This large park contains many of the typical mountain habitats, especially mixed-conifer woodland and riverside willow habitat. A good trail along an old narrow-gauge railroad bed follows the river for two miles through the property, and can be a good place to look for willow specialists like MacGillivray’s Warbler and Lincoln’s Sparrow. American Dipper can be common along the river and has nested just east of the parking lot. Also be sure to look for Canyon and Rock Wrens on the cliff edges south and east of the parking lot.
The large burn to the northwest of Pine Lake sometimes has American Three-toed Woodpecker, and ponderosa habitat in the area could contain Williamson’s Sapsucker, Pygmy Nuthatch, Western Bluebird, and others. More open meadows often contain Mountain Bluebird and White-crowned Sparrow, and Golden Eagles could soar overhead at any time.
Waneka Lake/Greenlee Wildlife Preserve
This lake in the middle of a neighborhood in Lafayette is a great place to look for birds in all seasons, along with the adjacent Greenlee Wildlife Preserve. In summer, Pied-billed and Western Grebes can be found on the lake, and Swainson’s Hawk is easily seen. In migration, migrant warblers and thrushes skulk in the undergrowth. Concentrations of Barn Swallows in late fall can be very impressive. In winter, ducks, geese, and gulls can congregate here, and the flocks can include rarities, such as Barrow’s Goldeneye and others.
Cheesman Park and Denver Botanic Gardens
Cheesman Park is another large city park with old trees and lots of potential for migrant birds. In some winters, the stands of coniferous trees can contain flocks of finches, and they could host roosting owls at any time of year. Across the road, the Denver Botanic Gardens are worth visiting just for the extensive and fascinating variety of plant life, but they can also be quite birdy at almost any time of year.
Drake Lake
A small lake with great marsh edges and a few trees, this area can be very attractive to ducks, geese, and especially gulls between fall and spring, as long as it is not frozen. The gulls gather here when they are not feeding in the nearby Weld County Landfill. In April and May, shorebirds can visit in good numbers.
Prewitt Reservoir State Wildlife Area
Prewitt Reservoir is a must-hit stop on any birding trip to the area during migration. Abundant riparian woodland, areas of marshes and prairies, and a lake that, depending on water level, may be absolutely chock-full of shorebirds and ducks make the SWA the perfect migrant trap. Birding at Prewitt tends to fall into two categories – walking the woods looking for passerines, and scanning the lake for waterbirds and shorebirds. For the former, there are two places to check: below the dam and the inlet canal.
The inlet canal tends to do a better job of concentrating birds, and if you only have time to visit one area, this would be the place. Below the dam has more expansive habitat and more variety (including some small marshes), but takes longer to visit. If you have enough time, visiting both is encouraged. The best place to scan the lake depends on the water level. There are several access points to the lake, and generally the best is right at the beginning of the dam. One can also walk along the dam to reach other parts of the lake, or walk in along the inlet canal. Hunting occurs on this property so be sure to check for seasonal restrictions before heading out. An annual permit is required unless you have already purchased a valid fishing or hunting license.
Mt. Galbraith Open Space
Situated low in the scenic Golden Gate Canyon, Mt. Galbraith Open Space is the first and best of several places to bird the area. A good walking trail passes both dense foothill scrub and cottonwood riparian habitats, eventually ascending into ponderosa pines. Lazuli Bunting can be wonderfully common here during the summer months, and even a few Indigo and hybrid buntings have turned up. Also look for Virginia’s Warbler, Woodhouse’s Scrub-Jay, Canyon and Rock Wrens in the rockier areas, and Say’s Phoebe throughout. Bighorn Sheep occur throughout the area, and while they are not common, a careful watch may turn up a few.
Julesburg
Two good places to bird in Julesburg are Lion’s Park, also known as the Julesburg State Wayside, and DePoorter Lake. Lion’s Park, along the South Platte River, features a Watchable Wildlife Trail where one can see Baltimore and Orchard Orioles, swallows, buntings, and warblers in migration. DePoorter Lake, just northeast of town, is a good place to see ducks and swallows in spring and fall. Look for other birds such as Wild Turkey and Great-tailed Grackle. A paved accessible walking trail circles the lake.
Lagerman Reservoir
Lagerman is known as a good place to find grebes, diving ducks, and gulls, especially in fall, and shorebirds such as Long-billed Curlew occasionally show up. A pair of Ospreys nest on a platform near the reservoir, and Yellow-headed Blackbirds breed just across the road. In winter, a large Prairie-dog town just to the west regularly attracts Ferruginous Hawk.
Ketring Pond
This little pond in the middle of Littleton Historic Park may not look like much at first glance, but it’s usually full to the brim with ducks. Most popular is surely the remarkably common Wood Duck, and this is among the best places in the state to get point-blank views of this gorgeous bird. A surprising variety of diving ducks can be seen during the colder months (until the lake freezes), occasionally including Barrow’s Goldeneye. A small trail system in the area offers some riparian habitat that could host migrants in season, and connects to a wider bike-trail system for anyone looking to embark on a longer trip.
88th Avenue Open Space
This area covers the gravel pits along the South Platte corridor between about 80th and 104th Avenues, including the area sometimes referred to by birders as ’88th and the South Platte’ or ‘the Dahlia ponds.’ This stretch is among the best spots for wintering waterfowl in the metro area. All the regular wintering dabblers and divers can usually be found with a careful search, and a couple of Barrow’s Goldeneyes are usually present – though finding them can sometimes require a long, cold walk! Long-tailed Ducks also occur here during some winters. Check for sparrow flocks in the riverside willows; with luck you might find a Harris’s Sparrow among the more common American Tree and White-crowned Sparrows.
Note: As of January 2018, this area is part of a major restoration and enhancement project. What is already good habitat for birds and other wildlife will only be improved, so visit in the future to explore the new enhancements!
Burchfield State Wildlife Area
Remote and little visited, this spot has the potential to be a first-class migrant trap. Tall cottonwood groves and a dense willow understory define this location. There is also some good brush along the small creek, and a small pond. This is a good spot to find Red-bellied Woodpecker. White-tailed deer, rabbits and foxes take shelter here in the only cover for miles in any direction.
Last Chance
Last Chance is a tiny town without services. However, it does have a rest stop backed by a small city park, and the grove of trees there is a legendary stopover spot for exhausted migrant birds traversing the dry treeless plains. Don’t drive past it without stopping in spring and fall–you never know what you might find.
Elbert Road and Elbert
This road runs south of Kiowa to the town of Elbert, and has in recent years been the most reliable place near Denver for Dickcissel, and is good for other grassland and edge species. The town of Elbert itself, in the heart of Elbert County’s ponderosa country, is a small town that also contains some nice riparian habitat. Outside town, look for Pygmy Nuthatch, Steller’s Jay and Western and Mountain Bluebirds; inside town, bird the riparian areas for migrants in season.
Klassen Farms
This site offers extensive shortgrass and sandsage prairie with a high probability of viewing Greater Prairie-Chickens. Four farmsteads on the property have migrant trap hedgerows, one of which has significant underbrush and another of which has a double row of tall ponderosa pines. Mountain Plover and Burrowing Owl can often be seen in summer; Barn Owl has nested in the grain bin. Stay at the guesthouse and wake up to life on a working ranch and farm that hosts all of the wildlife found in the region. The owner is sometimes able to provide tours, and is always willing to talk about modern agriculture and ranching.
Bader Ranch
This ranch in NE Las Animas County not only offers excellent pinyon-juniper woodland and cholla grassland, it also includes unbelievable beautiful canyons more in place in SE Arizona than SE Colorado. Look for Cassin’s Kingbird, Pinyon Jay, Rock and Canyon Wren, and Curve-billed Thrashers. The Baders have had a Vermilion Flycatcher nesting at their ranch the past couple of years. A herd of elk can sometimes be seen in the area, and keep an eye out for cool snakes in the canyons.
Holbrook Reservoir State Wildlife Area
This small lake is currently dry, however there are some pheasants in the area. When there is water in the reservoir and depending on water level, it can be awesome for shorebirds, terns, or waterbirds, and the grove is a first rate migrant trap. The lake can be scanned from the south side via the large parking lot, or along the west side via the rough dirt road. Look in the trees along the south side for migrants during spring and fall, and the southern shore for Black-necked Stilt and other shorebirds. Note that the trees to the south of CR FF are on private property and must be birded from the road.
Neeskah Reservoir (Queens State Wildlife Area)
Neeskah Reservoir, also known as Upper Queens Reservoir, is probably the reservoir in the area that gets the most shorebirds. When the water level is low enough to create mudflats, be sure to check the western edge of the lake via the multitude of access points. Neeskah can also be good for ducks, gulls, and an astounding number of Black Terns, in season. The riparian grove on the southern end of the reservoir can be well worth a stop for migrants and nesting Barn Owls. Lower Queens Reservoir (access closed from Dec 1-end of waterfowl season), just to the south, is usually better for waterbirds than shorebirds. The trees around the small parking lot can have migrants, and Cattle Egrets sometimes inhabit the nearby fields, along with coyotes, badgers, rattlesnakes and tarantulas.
Lory State Park
Lory State Park preserves excellent examples of prairie, shrublands, and pine forest habitats, bounded by granite cliffs along Horsetooth Reservoir. At lower elevations and along the main park road, birds of the shrublands, such as Woodhouse’s Scrub-Jay and Blue-gray Gnatcatcher, meet birds of the prairie, such as Western Meadowlark and Brewer’s Blackbird. Also look for soaring eagles, hawks, and falcons in the sky above. Other species of interest include: American Three-toed Woodpecker, White-throated Swift, and Greater Roadrunner. A State Parks pass is required for entry and hunting occurs at this location, so be sure to check for seasonal restrictions before visiting.
Westcreek
Lying at the edge of the huge Hayman Fire burn area (2002), Westcreek offers access to extensive tracts of burned woodland. Well into the regeneration process, this is still a good area to look for American Three-toed Woodpecker and other woodpecker species. Be aware the lake in the area is private property.
Valmont Reservoir complex
This complex of three reservoirs is an important birding spot in Boulder. In spring and fall migration, look for Western Grebes, Eared Grebes, and many ducks; Bald Eagle, Golden Eagle, and Ferruginous Hawk are also regularly seen hunting in the area. The reservoirs can be scanned at any time from Legion Park, where a scope is necessary. The area can also be accessed from the Open Space offices on the east side. When the gate is open, during business hours on weekdays, one can drive in, park at the Open Space offices, and walk west to the reservoirs, climbing the butte for the best view. Outside business hours, one can park outside the gate and walk a longer distance to the same destination.
Washington Park
Washington Park is full of old, large, and downright impressive trees, and should be checked at any time of year for a variety of birds. Perhaps most productive during migration, when you never know what could show up, they can also be worth a look in the winter when flocks of finches sometimes visit. In summertime, the two ponds in the park are usually full of paddleboats, but during colder months are more likely to have ducks, especially the late fall. Look especially for tame Wood Ducks and the occasional Hooded Merganser.
Raptor Alley
The Raptor Alley tour route was designed by “The Nunn Guy” to see most of the raptor species that can be found during the winter in Colorado. The trail originates from the Town of Nunn, perhaps one of the best places to see most common birds of prey and where some 23 species of raptors have been recorded. The tour encompasses many prairie dog towns and high-standing perches for raptors. This area also features Lapland Longspurs mixed in with flocks of Horned Larks in winter months. When driving on county roads, please watch for traffic and only pull over to look for birds in visible, safe locations. Also, be careful pulling onto the shoulder of roads, as many are soft and you could get stuck.
Atwood State Wildlife Area
This seldom-visited SWA provides good access to stretches of the South Platte River and associated riparian corridor. The best entry point is from the northern parking lot, especially east along the river. Look for sparrow flocks in winter, northeast specialties in summer, and migrants at other seasons. Scanning the river from the bridges may be worth your while; look for dabblers, Belted Kingfisher, and possible shorebirds when the water is low enough to expose sandbars. Hunting occurs on this property, so be sure to check for seasonal restrictions before heading out.
Lookout Mountain Nature Center and Preserve
One of the nearest locations to Denver offering extensive ponderosa woodland, Lookout Mountain is an easy morning trip from the metro area that can add a lot of variety to your list on a visit to the city. And the park is worth a visit for its expansive views of the Denver area alone! All the typical ponderosa birds are possible, including Williamson’s Sapsucker, Pygmy Nuthatch, Western Bluebird, Cassin’s Finch, the occasional Evening Grosbeak, and (with a good deal of luck) Dusky Grouse. For the latter, look around the parking lot in the early spring. American Three-toed Woodpecker has even been seen here, though it is uncommon at best. Several mammal species not typically present this close to Denver could be seen, including bighorn sheep and elk. Be sure to stop in the Nature Center for a schedule of educational programs and more! Be aware dogs are not allowed at the Preserve.
Ovid Woods
A strip of woodlands along the east edge of the town of Ovid, called the ‘Ovid Woods,’ is private property and cannot be entered, but it is possible to see many birds from the road that runs along it. Breeding birds here include Red-headed and Red-bellied Woodpeckers and Chimney Swift; Northern Cardinal is sometimes seen. Good numbers of migrant warblers and sparrows can be found during migration.
Golden Ponds Park
Surrounded by a magnificent view of Longs Peak and the Front Range, the reclaimed gravel pits here should be checked for ducks in the colder months, as a Tufted Duck famously stopped by for a few days one winter. Wood Ducks, Bald Eagles, and Ospreys are regularly seen, as well as all six of Colorado’s swallow species swarming over the water in late April and May. In spring and fall, check for migrants in the woods along the Saint Vrain Greenway bike path, which begins here and runs all the way to Sandstone Ranch east of town.
South Platte Park
The extensive South Platte Park, just to the north of C-470, has both an excellent trail system and a wide variety of habitat – the perfect birding spot for a short outing or a longer bike or walking trip in the south metro area. Several small but productive ponds can be found to the south of the Visitor’s Center; check for a wide variety of species that often include several divers during the colder months, and even rarities at times. The extensive riparian corridor has breeding Great Horned Owl, Eastern Screech-Owl, Yellow-breasted Chat, Bullock’s Oriole, and Lazuli Bunting among the more common birds, and can act as a magnet for migrants during fall and spring. While wintertime in the area tends to be slower, the abundant thickets usually have several sparrow species, and it is a good time of year to look for American Dipper on the river. Be sure to visit the Carson Nature Center, which has interactive nature exhibits and live animals on site.
Rocky Mountain Arsenal National Wildlife Refuge
Historically recognized as a Superfund clean-up site, today the Arsenal has been resurrected as a first-class wildlife refuge. Among Denver-area birders, it is known as a good place to look for raptors, and one of the best spots near the city for Ferruginous Hawk. The small lake near the former Visitor’s Center can have various ducks in season, and has pulled in a few rarities such as scoters. Lake Ladora has a parking lot on its west side and often contains lots of water birds and easy walking around the lake in either direction. The open prairie houses Burrowing Owls and can even have breeding Lark Buntings. In winter, there are often double-digit Bald Eagles in the area. In 2015, the refuge re-introduced the endangered black-footed ferret back to the property and an outdoor ferret exhibit can be viewed just outside the Visitor Center’s back patio. Visitors can also see a small herd of American bison, which were re-introduced to the Arsenal in 2007.
Public access is limited to certain parts of the refuge; guided trips deeper into the property leave periodically. Be sure to stop by the Visitor’s Center to inquire about guided trips as well as check out their interactive exhibits.
Walsh
A small town in far eastern Baca county, Walsh has a surprising number of trees and owls are very prevalent here. Also, worth a check for migrants. It is also the only place around the get gas or food.
Ramah State Wildlife Area
A remote medium sized reservoir, this location is excellent for waterbirds, shorebirds, and migrants. The large riparian area on the west side can be birded from the road, and should be checked for migrants and a few breeding species of birds. The lake, when low, is among the best shorebird spots in the area. In the winter, look for sparrows in the thickets, and ducks on the reservoir if it is not frozen. The prairie in this area supports Swift Fox and tarantulas among other interesting wildlife.
Kim
This town is the epitome of a remote plains village. A fun informal restaurant at the only gas station in the area makes this a good stop while driving through. Eurasian Collared-Doves, Great-tailed Grackles and occasionally Cassin’s Kingbirds can be seen in town, and in season, Black-chinned Hummingbirds are common at local feeders. Keep an eye out for Golden Eagles and Ferruginous Hawks.
Cholla patch near Fowler
A small, privately owned patch of cholla near Fowler is a great place to look for desert birds like Curve-billed Thrasher, Scaled Quail and Greater Roadrunner, although none of them are common. You might also see Wild Turkey, Northern Mockingbird and even Coyote. Viewing from vehicle only, private property on both sides.
Thurston Reservoir State Wildlife Area
Thurston is one of the only bodies of water in Prowers County. In recent years it has run low (even dry) and large parts of it have grown up in cattails. However, this makes good habitat for rails and bitterns, and ducks still swim in the open channels. Nearby fields can attract huge flocks of Sandhill Cranes in migration, and there are sometimes thousands of Snow Geese here in the winter. Pronghorn are sometimes numerous in the area. Look also for mule and white-tailed deer, coyotes, red fox, rabbits and prairie dogs.
Rist Canyon
This canyon is a premier area for those seeking foothills and mountain birds. In the lower parts of the canyon, riparian areas host Lazuli Bunting and Yellow-breasted Chat. Higher up in the pines, one can find Dusky and Hammond’s Flycatchers, Steller’s Jay, Mountain Chickadee, and Red Crossbill. In 2012, a fire burned much of this area, creating open meadows now inhabited by Mountain and Western Bluebirds. However, many of the best tracts of forest remain untouched, including a lush section half a mile above the turnoff to Stratton Park Road that boasts breeding Ovenbird and Virginia’s Warbler. Note: it may be difficult to find places to stop along the road, so please use caution when exploring this area.
Bobolink Trailhead
From late May through mid-July, the stars of the show along this trail are – you guessed it – Bobolinks! This is one of the few reliable nesting sites for the species along the Colorado Front Range. A nice riparian walk along South Boulder Creek provides viewing of some water and forest birds and adjacent tallgrass prairie provides habitat for grassland birds. Also watch for foxes and coyotes in the fields.
May Farms
May Farms features easy access east of Denver off I-70 with a 1/2 mile of West Bijou Creek that includes a deciduous riparian forest. The May family has been pioneering agritourism since the early 2000’s on their farm. Great Horned Owls, Bald Eagles and variety of other raptors and songbirds nest on their property. They also have a pond that attracts waterfowl year-round.
The farm is a popular venue for concerts, weddings, and other special events. Features such as corn mazes, pumpkin patch picking, and other farm-related activities with the livestock they raise draw a diversity of visitors. The farm offers an office building, shop, and huge pavilion, which is perfect for large group activities. They are open to the public for farm-to-table meals on Thursday and Friday nights 5:00PM – 8:00PM
Fairmount Cemetery
This large cemetery is covered in beautifully old and impressive trees, especially conifers. And unlike most trees in such places, they aren’t trimmed close to the ground, providing more cover than in most urban parks and cemeteries. Look especially for finches in the winter, when birds such as Red Crossbill, Cassin’s Finch, and even the occasional Evening Grosbeak are possible (but don’t expect any particular species in any particular year). During spring and fall, any number of migrant species could occur, and this seems to be an especially good place to look for Townsend’s Warbler during the fall. You may even want to join Denver Field Ornithologists on a free guided bird walk they offer here (which they also offer at Riverside Cemetery in North Denver).
Crom Lake
Crom Lake is a small pond near the town of Pierce and is a reliable place to see ducks, pelicans, and herons; sometimes it hosts impressive numbers of geese or shorebirds in spring migration. The lake is on both sides of the road, and good birds can be seen on either side. The lake tends to freeze in colder months and during summer hosts fewer birds, but prairie species such as Burrowing Owl and McCown’s Longspur can sometimes be found in the surrounding area.
Sterling
As the largest town in northeastern Colorado, Sterling is the logical base for a trip to the area, and several town parks are worth a visit whether you’re staying overnight or stopping by for the day. The Overland Trail Recreation Area gives access to the South Platte River and its associated riparian habitat, while Pioneer Park just to the west of town has the best migrant traps. Both locations could have Mississippi Kites, which only breed in a few places in this part of the state, as well as migrants in season, sparrows in the winter (including Harris’s Sparrow with luck), and others.
Apex Park
Like nearby Red Rocks Park, Apex has some beautiful foothill scrub with the associated birds. Unlike Red Rocks, there are rarely hordes of people here! This relative quiet allows for a more pleasant walk while you’re looking for Canyon Wren, Lazuli Bunting, Spotted Towhee, Yellow-breasted Chat, or other breeders in the area. A few migrants pass through during spring and fall, but the winter months tend to be slow at best. This area is among the best places in Colorado to search for the rare Moss’s Elfin butterfly.
Jumbo Reservoir State Wildlife Area
Labeled ‘Julesburg Reservoir’ on some maps, this place is known by locals as ‘Jumbo.’ Birding can be excellent here at any time of year. Large numbers of shorebirds can congregate on mudflats in late summer and fall; up to five species of geese may gather in enormous flocks in the colder months (as long as there is open water). Sabine’s Gull is regular in fall, jaegers are occasionally seen, and even a Ross’s Gull once showed up here! Great Horned Owls and Eastern Screech-Owls have nested in the small primitive campground. Breeding birds in the fields around the reservoir include Upland Sandpiper, Burrowing Owl, Dickcissel, and Grasshopper Sparrow. Golden Eagles and Ferruginous Hawks are sometimes seen. An annual permit is required to access the property unless you have already purchased a valid Colorado fishing or hunting license.
McIntosh Lake
From the city park on the south shore, scan McIntosh in the colder months for waterbirds of any stripe. Shorebirding can be good if the water levels are right. Bonaparte’s Gulls often hang out here in November and a number of rarities have been found here, from Brown Pelican to Great Black-backed Gull. You never know what you might find!
McLellan Reservoir
Sitting safe behind a high fence, McLellan Reservoir is not accessible to the public. However, a good pullout along County Line Road lets you safely park and scan the lake, which is often full of waterfowl from fall through spring. Less common species like Hooded Merganser and Canvasback can be spotted, as well as the occasional Barrow’s Goldeneye among the more common species. When an ice shelf forms, gulls can congregate along its edge. The Highline Canal bike trail has a spur that rings the northern end of the reservoir, and there are several places you can scan through the trees to get a different perspective, as well as check for passerines and Great Horned Owl in the riparian habitat.
Barr Lake State Park
One of the premier metro-area lakes, Barr Lake has been a hot spot for birding longer than just about any other place in Colorado. Visit here and you will see why! Depending on the season, there are many opportunities to view waterbirds, shorebirds, raptors, and songbirds. An impressive riparian area surrounds the lake on all sides and provides ideal habitat for both resident and migratory birds. The wildlife refuge located at the southern end of the lake provides additional cover and protection, particularly for nesting birds, including a resident pair of Bald Eagles and a rookery with over 200 nests used by herons, egrets, and cormorants. In winter, it is possible to see large numbers of Bald Eagles at one time, as well as a variety of waterfowl and shorebirds, such as goldeneyes, grebes, gulls, and terns. Other birds of interest you could spot at Barr include: large variety of warblers, longspurs, and sparrows. Over 350 species of migratory and resident birds have been observed at the park, so there is always something to see year-round!
In the fall, Bird Conservancy of the Rockies operates a banding station to the north of the Nature Center along the perimeter trail. This is an excellent opportunity to view migrating birds both in the hand and in the field. Be sure to stop by Barr Lake’s Nature Center to learn more about their annual Birding Festival (in early September) and Bald Eagle Festival (early February), as well as a multitude of other educational opportunities.
There are two entrances to the park, the main entrance on the southeast side leads to the Nature Center and other amenities while the northern entrance leads to Bird Conservancy of the Rockies Environmental Learning Center. You can access the perimeter trail from both entrances. A state park pass (annual or day) is required for entrance and parking.
Please note: dogs are not allowed in the Wildlife Refuge.
Cope
Cope is a small and charming town with a lot of big trees but few amenities. Eurasian Collared-Dove is abundant here, and rare doves sometimes occur. Look out for migrant landbirds in spring and fall, and sapsuckers sometimes spend the winter.
Sears Range
This site offers over 480 acres of ungrazed shortgrass prairie. It is a new ranch being managed for conservation purposes, and currently the only domestic inhabitants are three friendly, rescued llamas. This is a good location for grassland specialities, one of the closest places to Colorado Springs where you might find Grasshopper Sparrow, Cassin’s Sparrow, and many other birds.
Mills South
This working farm offers several areas that offer excellent hiking and prairie wildlife-viewing. The owner is sometimes available to give tours, and is very knowledgeable about local natural and cultural history.
Mayfield Ranch
This ranch, owned and operated by Mary and Gary Mayfield, is just a few miles upstream from Cottonwood Canyon along West Carrizo Creek, and nestled against the northern flank of the Black Mesa. The real draw here for birders is more than a mile of riparian deciduous growth along a permanent stream. The cottonwoods, boxelders and hackberries along the creek shade dense willow thickets and other underbrush. Pinyon-juniper forest flanks the shallow rimrock canyon. Along the creek, look for things like Eastern Phoebe, Bewick’s Wren and Ladder-backed Woodpecker, and in migration for eastern vagrants galore. The pinyon-juniper and rimrock could produce Rufous-crowned Sparrow and Greater Roadrunner, while hummingbird feeders at the Mayfield’s house are a magnet for Black-chinned Hummingbirds. Wild Turkeys often hang around the homestead in large numbers, and deer are frequently seen. The Mayfields also have a couple of very nice options for birders looking for accommodations, including a furnished trailer house and a cute adobe bungalow. They ask $25 per night per bed.
Fowler
The town can be decent for migrant landbirds, but the best show in town is usually at the sewage ponds, just north of town and south of the river, on the east side of CO 167. The two westernmost ponds can be scanned in basic fashion from outside the fence, and can be swarming with birds.
Watson Lake State Wildlife Area and Bellvue-Watson Fish Hatchery
This small State Wildlife Area sits at the base of a cliff that is a traditional nesting site for Golden Eagles, White-throated Swifts, and Canyon Wrens. The lake attracts waterfowl in late fall and early spring, including Hooded Mergansers. Please note public access is prohibited on the northwest side, as posted. Stop by the nearby Bellvue-Watson Fish Hatchery, as self-guided tours, fishing, birdwatching, and nature trails make this an excellent education and recreation destination.
Baseline Reservoir
This private lake is a good place to look for migrating loons and diving ducks, including scoters, in late fall. Sometimes gulls roost on the southwest shore, near the road, where they are easily viewed. In winter, if the water is open, you may see some rare birds on the lake. The easiest viewing of the reservoir is on the southwest side, off Cherryvale’s wide shoulder. Please watch for traffic.
Aurora-Kelley Reservoir/Westerly Wetlands
The Aurora-Kelley Reservoir on Westerly Creek is a large flood control area in the Lowry neighborhood of Denver. Behind the dam, you can find an extensive permanent cattail marsh and gravel/dirt walking trails. Look in season for White-faced Ibis and Yellow-headed Blackbird, both hard to find in the area. Common birds include Red-winged Blackbird, Western Meadowlark, Killdeer, and Snowy Egret. It’s also a good spot for grebes, phalaropes, swallows, and sparrows. Continue walking to Great Lawn Park, where two small ponds also attract a diversity of waterfowl and other birds. Note: Amenities listed can be found at Great Lawn Park.
Clark Lake
This small lake is just southeast of the town of Ault and can attract good numbers of geese in winter, along with various ducks. In spring and summer, look for Bullock’s Oriole in the cottonwoods around the lake, and Yellow-headed Blackbird in the cattails.
North Sterling State Park
North Sterling State Park is a large reservoir in northeastern Colorado, which includes a variety of habitat types, such as shoreline, wetlands, woodlands, cliffs, and prairie. This park provides great opportunities to view many of the birds particular to northeastern Colorado. The reservoir can attract various ducks, ibis, loons, and grebes. Forested areas can host breeding Bullock’s, Baltimore, and hybrid orioles, Indigo Bunting, Eastern Kingbird, and Bell’s Vireos. During migrations, you never know what could turn up! In the prairie habitats of the park, keep an eye out for Lark Bunting, Western Meadowlark, Brewer’s Sparrow, Ferruginous Hawk, and flocks of longpurs in winter. Unexpected species could include Eared Grebe, White-faced Ibis, Sandhill Crane, and Long-eared Owl. A State Parks pass is required for entry and hunting occurs on this property, so be sure to check for seasonal restrictions before visiting.
Genessee Park
As City of Denver’s first and largest mountain park, Genessee is the classic ponderosa forest location near Denver, and offers easy access to the various species preferring this habitat. Look especially around the parking lot at the top of the road ascending off of I-70 for Williamson’s Sapsucker (March-October), Pygmy Nuthatch, Cassin’s Finch, Western Bluebird, and more. The lower Chief Hosa section of the park, on the other side of I-70, traverses a more riparian habitat and has species such as Western Tanager, Warbling Vireo, Lazuli Bunting, and Spotted Towhee. Make sure to stop by the Buffalo Herd Overlook to see Colorado’s first bison herd, re-established in 1914.
Red Lion State Wildlife Area
Adjacent to Jumbo Reservoir, Red Lion SWA is centered around a lake affectionately known as “Little Jumbo.” While not usually as productive as the larger Jumbo, the reservoir here is often filled with Snow and Ross’s Geese during winter, and a few Greater White-fronted Geese can often also be found. Nearly every duck species that occurs on the plains could be seen here, as well as Eared and Horned Grebes, and the occasional loon or flock of American White Pelicans. When the water is low (usually during the fall months), hundreds of shorebirds can occur, and nearly any species is possible. The open, sandy prairie surrounding the lake usually hosts Lark Bunting, Western Meadowlark, Western Kingbird, and Swainson’s Hawk, as well as the occasional Upland Sandpiper. During the winter, look for Rough-legged Hawk and Lapland Longspur. Hunting occurs on this property, so be sure to check for seasonal restrictions before heading out.
Pella Crossing Park
The Pella Crossing and Marlatt Open Space properties are located west of Longmont near the St. Vrain Creek. Both properties provide significant habitat for waterfowl and other wildlife and offer recreational opportunities, primarily in the form of fishing and trail use. The fields to the east have attracted Dickcissel and Grasshopper Sparrow in some summers. Following the trails west to the trees is a good way to find spring migrants. A colony of Great Blue Herons nests in the trees just across the river to the west.
High Line Canal (Douglas County portion)
While rarely used as a canal these days, the extensive bike trails and beautiful riparian habitat make this woodland corridor the perfect place to combine a morning jog or bike ride with some birding. During migration, look for various songbird migrants, and during summer, check for Lazuli Bunting, Yellow-breasted Chat, Spotted Towhee, Great Horned Owl, and more.
You can read about author Robert Michael Pyle’s adventures growing up along the High Line Canal in The Thunder Tree: Lessons from an Urban Wildland.
Brighton
Brighton provides the closest facilities to famed birding locations such as Barr Lake, in addition to several nice city parks. The best of these is Veterans Park on the South Platte River, which is contiguous with the Getz and Morgan-Smith Nature Areas. Extensive riparian habitat offers chances at various migrants in season and the usual suite of breeding species, while the river can host waterfowl during the winter (including Common and Hooded Mergansers and Common Goldeneye), as well as flocks of sparrows in the associated scrub. Check the gravel pits at Ken Mitchell Park (ebird hotspot checklist) and adjacent Ergers Pond for diving ducks during the colder months, as Barrow’s Goldeneye and Red-breasted Merganser have been seen here among the more common species.
Idalia
This small town has some nice big trees, both deciduous and coniferous, and so may function as something of a migrant trap, possibly worth a stroll in fall or spring. Collared-Doves are numerous, and Great-tailed Grackles may breed. South Republican SWA is nearby for hunting, fishing and camping.
P & P Cattle Company
Situated in the heart of El Paso County’s shortgrass prairie, P & P Cattle Company offers viewing opportunities for many regional specialties including Burrowing Owl, Mountain Plover and Ferruginous Hawk. Depsite being located in an area where surface water is tremendously scarce, the P & P property is home to no fewer than nine playas that when wet may host a number of migrating shorebirds and waterfowl. The owners have worked with numerous conservation organizations to help protect and conserve the playas on their land. P & P Cattle is a working ranch with direct market beef and pork available. For more information contact Gary Paul at (719) 478-2039.
Burlington
This large town is one of the few in the area that has all the amenities, and can also be an excellent birding stop. The sewage ponds just south of town can be excellent for ducks and other assorted waterbirds. The cemetery north of town has some large trees. Around town itself are many large trees that are worth a look, especially during migration.
Timpas Creek State Wildlife Area
This SWA just south of La Junta has some small but dense groves of trees that can contain migrants, and the canal with its large cottonwoods could have Mississippi Kites, among others. The small ponds are worth a look for ducks, and the area around the trees can harbor rabbits and squirrels.
Reservoir Ridge Natural Area
This popular hiking trail includes grassland, mountain mahogany shrub steppe, and some ponderosa pine habitats. There are three entrances, but the trail from the parking lot on Overland Trail Road passed through an area that can host Bobolinks during summer months. This has been one of the most (if not the only) reliable places to find Bobolinks in Larimer County.
Doudy Draw and the South Mesa Trail
These open space trailheads near Eldorado Springs provide access to miles of hiking trails and some riparian habitat along the creek. Look for Spotted Towhee, Yellow-breasted Chat, Blue Grosbeak, and Blue-gray Gnatcatcher in dense scrub, as well as the occasional Red-eyed Vireo in taller trees. Lazuli Bunting is common in summer; Indigo Bunting and hybrids are uncommon to rare. Keep an eye out for herds of mule deer and elk along the trails. For a first-class birdwatching destination, follow the South Mesa Trail to the Towhee Mesa Loop/Towhee Homestead Loop, which includes rich grasslands, forest communities, and lots of shrubby drainages. A side trip along the Upper Big Bluestem Trail is also great for birds. Note: there is a fee to park at this property.
Bluff Lake Nature Center
Along the Sand Creek Greenbelt, Bluff Lake Nature Center makes for an excellent place to spend a morning and check out a number of different habitats. Perhaps the best of these is a truly excellent marsh, with Virginia Rail and Sora, Marsh Wren, and maybe even American Bittern. The riparian corridor along the greenbelt is well worth checking for migrants, in season, while the lake itself often has a variety of ducks that can include Cinnamon and Blue-winged Teals, Hooded Merganser, and Canvasback, among others. Note: dogs are not allowed at this property.
Crow Valley Campground
This Forest Service campground is one of the only places on the Pawnee National Grassland with water and trees, which makes it a prime destination for migrant birds in spring and fall. Warblers, vireos, thrushes, and flycatchers can sometimes be numerous in the campground, with good chances for vagrants from the east. Eastern Screech-Owls nest here, and in winter, Long-eared Owls sometimes roost in the evergreens. The areas on the south edge and north edge of the campground are usually better areas and have trails. The trail to the north starts at the group campground at the northwest corner of the campground and birders are allowed through the gate (be sure to close it) on the trail and onto the land north, but please leave nothing behind when you leave. During spring, there can be White-faced Ibis and other wading and water birds in that area to the north. The campground is very popular with visitors on spring and summer weekends, and please note that hunting occurs here in season. The campground is closed from November to April, but you can still park outside the gate and walk in.
Matthews/Winters Park and Dinosaur Ridge Hawk Watch
Colorado’s only hawk watch site, staffed every spring by volunteers, Dinosaur Ridge is one of the best places to look for raptors along the Front Range. The best time for viewing tends to be from late March through early May when, on a good day, dozens of raptors can pass by overhead. Dinosaur Ridge holds the record for the national high count of Ferruginous Hawks (over the course of a spring) and is also the best spot in Colorado to hope for Broad-winged Hawk during migration; however, this species is uncommon at best and not to be expected.
The juniper woodland often has flocks of Bushtits roving the hillsides, along with Woodhouse’s Scrub-Jay, and Rock and Canyon Wrens inhabit the nearby cliffs and rimrock. Don’t forget to stop at the Dinosaur Ridge Visitor Center to learn more about the area’s dinosaurs and more!
Ish Reservoir
This private lake can be well-scanned from a quiet county road. It is one of the better places in the area to look for shorebirds, especially in late summer and early fall, when Blue Grosbeaks are often still singing along the road. Please be sure to respect private property.
Cherry Creek State Park
One of the crown jewels of Denver area reservoirs, Cherry Creek is famed among birders in the state both as a rarity magnet and an all-round good birding location. The reservoir typically ices over for a short time typically between December through the end of March. There are a number of good locations to observe birds around the reservoir from various viewpoints onto the lake; as a general rule, the southern parts of the lake are better for shorebird species (especially when the water is low), while areas closer to the dam tend to have more diving ducks. Gulls congregate around the marina and swim beach during colder months, and birds like loons and grebes are most often seen in the middle of the reservoir. In summer months, the extensive cottonwood forest along Cherry Creek is home to breeding species such as Yellow-breasted Chat and Yellow Warbler. Check for raptors, sparrows, flocks of Horned Lark, and the occasional longspur in the open prairie habitats on the western part of the park. A State Parks pass is required for entry.
North Star Reservoir
This pond can be scanned from a county road and can hold a good diversity of ducks and other waterbirds at almost any season. In warmer months, huge flocks of swallows can swarm over the surface of the water.
Sandy Bluffs State Wildlife Area & State Trust Land
A large and beautiful piece of state land north of Idalia, Sandy Bluffs overflows with sandsage, yucca slopes, and eroded outcrops. Watch for Rock Wren, raptors, and sparrows (Cassin’s, Lark and Vesper in the warmer months, White-crowned and possibly White-throated and Harris’ in the colder months). Coyotes, pronghorn, jackrabbits and even bobcats and porcupines may be found on the property. The land is bisected by the Arikaree River, and a good deal of the mature cottonwood forest along the river bottom is accessible on foot.
Karval Area Ranches
In combination, these three ranches offer unparalleled access to the heart of Colorado’s shortgrass prairie. All family-owned and operated, these working ranches have a strong commitment to agricultural lifestyles as well as the wildlife and other natural resources that abound on their land. They have undertaken multiple habitat enhancement projects including playa lake, riparian and native rangeland restoration. All three ranches are dominated by native blue grama and buffalo grass rangeland and host the suite of shortgrass prairie birds including Burrowing Owl, Mountain Plover, Ferruginous Hawk, Swainson’s Hawk, Prairie Falcon, Long-billed Curlew, Cassin’s Sparrow, Lark Bunting and many more. A portion of Horse Creek runs through the Stogsdill and Davis ranches, with a cottonwood canopy that makes excellent habitat for riparian nesting and migrant songbirds. All three ranches have playa lakes that when wet can make for remarkable birding, with the potential to see any of the 27 shorebird species that migrate through eastern Colorado, as well as nesting American Avocets in some years. The Thornton Ranch is home to a 43 acre playa that is 3 miles from the nearest county road. The exceptionally remote location offers fantastic birding both in the upland black-tailed prairie dog town and in the playa when it is wet. For more information and to access the sites contact Carl and Cherry Stogsdill at (719) 446-5354 or rainbowvalley@prairienetworks.com.
Rhoades Brothers Ranch
The Rhoades Brothers Ranch lies approximately 15 miles north of Burlington and offers thousands of acres of unexplored country in proximity to Bonny Reservoir. The ranch consists of mainly short- and mixed-grass prairie and is home to Burrowing Owls, Ferruginous Hawks, and Grasshopper Sparrows. Around ranch headquarters, breeding Barn and Long-eared Owls have both been recorded. To explore the ranch and get directions, contact Bobby Rhoades at 719-346-7350 or bsbb@rebeltec.net.
McComber Ranch
This ranch offers several hundred acres of birdwatching on shortgrass prairie, as well as access to Timpas Creek. On the prairie you may find Mountain Plovers and Long-billed Curlew, with luck, and pronghorns are fairly numerous. Stay at the family-style bunkhouse, which sleeps 4 to 5 adults and 2 kids. Two kids can also sleep in the old-time sheep wagon. Enjoy campfires and chuckwagon cooking when time and weather allow. Watch horse-training and western leather-working on site.
Poudre Trail – Ft. Collins Section
This 10-mile paved bike trail follows the Cache la Poudre River, connecting the towns of Bellvue, LaPorte, and Fort Collins, and running through a rich strip of riparian forest. Look for a variety of migrant birds in May, including flashy Western Tanagers, Black-headed Grosbeaks, and warblers. Species such as Eastern Kingbird and Western Wood-Pewee may breed side-by-side here. Also look for Red Foxes and Raccoons in the woods. There are a number of parks and other trail connections along this route, allowing for hours of outdoor exploration! The City of Fort Collins plans to expand the corridor east toward I-25 so stay tuned for future opportunities. For a longer day, stop by the Fort Collins Museum of Discovery to learn more about the area’s local natural history, as well as see their live black-footed ferrets on display.
Eldorado Canyon State Park
Driving into Eldorado Canyon, you will be rewarded with spectacular views of enormous cliffs where Canyon Wrens, White-throated Swifts, and Violet-green Swallows nest. World-renowned as a premier rock climbing destination, it’s hard not to spend a little time also watching the brave climbers scaling Eldo’s dramatic sandstone cliffs!
South Boulder Creek carves a path through the canyon, providing potential for seeing American Dipper in the rushing stream. Farther inside the park, the landscape flattens and an extensive trail system begins, providing access to mixed conifer forest with typical foothills species ranging from Western Tanager to the striking Abert’s squirrel. Other birds of interest you could possibly spot here include: Lewis’s Woodpecker, Prairie Falcon, Golden Eagle, Virginia Warbler, and Chestnut-sided Warbler. A State Parks pass is required for entry. Hunting occurs at the Crescent Meadows portion of the park, so be sure to check for seasonal restrictions before visiting that section.
Sand Creek Greenway
The Sand Creek Greenway, connected to the larger Denver-area bike trail system, has some of the best riparian corridors in the area. The Greenway is the perfect spot to enjoy a longer bike ride or walk without going too far from the city. The woodland here should be checked for a variety of migrants during spring and fall, and for birds like Downy and Hairy Woodpeckers, Yellow-breasted Chat, Bullock’s Oriole, and Lazuli Bunting in the summer. Wintertime tends to be slower, but flocks of sparrows sometimes haunt the thickets, and Great Horned Owl can be found all year.
Pawnee National Grasslands (western section)
The Pawnee National Grassland is one of the premier patches of shortgrass prairie remaining on the Great Plains, a haven for a suite of prairie birds increasingly scarce elsewhere: Ferruginous Hawk, Mountain Plover, Long-billed Curlew, Burrowing Owl, McCown’s and Chestnut-collared Longspur, Grasshopper Sparrow, and Colorado’s striking state bird, the Lark Bunting. In some years, Cassin’s Sparrows are numerous. Pronghorn and black-tailed prairie-dog are hard to miss, and coyotes are sometimes seen, along with the occasional swift fox. The National Grassland is a complex and remote patchwork of federal, private, and leased lands; a good map is essential for navigating the area.

Red Rocks Park
Famed the world over as a musical venue and for its spectacular scenery, Red Rocks is also one of the best birding locations in the Denver area foothills, at all times of year. During colder months, the feeders at the Trading Post can draw in large numbers of birds, including the full suite of Dark-eyed Junco subspecies, Cassin’s and House Finches, and sometimes a rare sparrow. Occasionally flocks of rosy-finches are found here, though their presence is erratic at best, and mostly occurs during winter storms.
As the year begins to warm, several foothill species like White-throated Swift, Canyon and Rock Wrens, and Lazuli Bunting begin to show up and hang around through summer. Migrants are sometimes found during both the spring and fall, and there is a good shot at seeing both Prairie and Peregrine Falcons if you keep an eye to the sky – both species nest here.
Ron Stewart Preserve at Rabbit Mountain Open Space
Rabbit Mountain is a low hill covered with dry scrubby vegetation that looks more typical of Southwest Colorado than the Front Range. This unique habitat makes it one of the best places in the area to find species of dry, open country such as Bushtit, Common Poorwill, and, if you are lucky, Pinyon Jay. Be on the lookout for Say’s Phoebe and Rock Wren breeding near the parking lot. This is also a great place to see Elk, as well as find lizards and snakes in summer, including rattlesnakes, so be alert when hiking.
Aurora Reservoir
Situated a bit east of the Denver metro area, Aurora Reservoir sits outside the main urban sprawl that defines the city meaning this lake is still surrounded by a good-sized block of native prairie habitat, and is also more likely to catch birds migrating away from the mountains. The reservoir has excellent access, with a road around the lake offering many prime viewpoints, and provides good facilities making for an easy visit. Check the lake itself for the full variety of waterfowl from fall through spring, including good numbers of diving ducks and a better chance at Snow and Ross’s Geese than most Denver-area lakes. As a result of nearby landfills, gulls are often found here in numbers, and this is a good place to look for less common species such as Thayer’s, Lesser Black-backed, and Glaucous Gulls. The prairie habitat occasionally has Lark Buntings, Horned Lark, and Lapland Longspur during the winter, as well as a variety of sparrows and raptors. There is a fee for entrance.
Fort Lupton
The highlight of birding in the Fort Lupton area is Pearson Park, west of town along the South Platte River. Here, underneath the tall cottonwoods north of the baseball diamond, are thickets of Russian-olive and willow that are home to Downy Woodpecker, White-breasted Nuthatch, Blue Jay, and other typical birds of riverside woods. In spring, look for migrant warblers and thrushes. A patchwork of dirt trails runs through the trees.
Beecher Island area
The Beecher Island Battleground, a National Historic Site, is on private land that permits public access. The site contains a memorial, an informational display, a beautiful picnic area in the middle of mature riverbottom cottonwoods, and a one-mile nature trail through native sandsage prairie, river bluffs, and trees. The Arikaree River bottom mostly lacks underbrush, but some junipers around the buildings provide cover, and the tall trees are likely to host woodpeckers, nuthatches, owls and migrant passerines in season. Visit Simmons State Wildlife Area.
Peyton Place
Watching a Prairie Falcon stoop on a raft of Gadwall while several hundred low-flying Sandhill Cranes circle above on a golden September evening is only one example of a scene you might expect to see at Peyton Place. Located several miles south of the town of Karval, the ranch lies on a hillside between shortgrass prairie and sandsage breaks. The unique feature on this ranch is the ten spring-fed ponds nestled in the hillside, offering scenery and habitat remnant of the Dakota potholes region. The ponds offer some of the only permanent water for many miles and provide critical stopover sites for a number of waterfowl and shorebird species. In addition to the water features on the ranch the uplands provide hundreds of acres of unexplored country. For more information and directions, contact Dan Merewether at (719) 446-5403 or dmerewet@plains.net.
South Republican State Wildlife Area
This location covers most of the area below the dam at Bonny. There is more wildlife here than at many other plains reservoirs and river bottoms; few visitors to the reservoir head east below the dam, to the State Wildlife Area that runs along the river all the way to the Kansas state line. Habitat varies from yucca grassland and large hedgerows to lowland riparian. The hedgerow at Hale is enormous, and a good spot for Northern Cardinals, sparrows during the winter, owls, and migrants. The Hale Ponds SWA is excellent for Eastern Screech-Owl, Wild Turkey, Northern Bobwhite and migrants, not to mention white-tailed deer. The grassland between the dam at Bonny and the above locations can have Cassin’s and Grasshopper Sparrows, among others.
Douglas Reservoir State Wildlife Area
This large reservoir can be very good for waterbirds, especially in late fall before it freezes. Watch for Bald Eagles, various ducks and gulls, the occasional loon, and Northern Shrike in winter. Keep your eye on the surrounding shrublands for visiting and nesting birds.
Lower Bear Canyon Trail
This easy trail leaves a neighborhood and parallels a shrub-filled drainage up into the ponderosa pines. Look for Bushtit, Spotted Towhee, and both Blue and Steller’s Jay. It is good place to see migrant birds in late spring, and Virginia’s and MacGillivray’s Warbler in summer.
Utah Park and Jewell Wetlands
This small park with a tiny pond doesn’t typically attract a huge variety of birds, but the Jewell Wetlands adjacent to it, with its well laid-out boardwalk, has some of the best access to marshland in the area. Look for Virginia Rail and Sora, Marsh Wren, and (with a good deal of luck), the occasional American Bittern.
Pawnee National Grasslands (East Section) & Pawnee Buttes
One of the most beautiful spots on Colorado’s eastern plains, the Pawnee Buttes are featured on many a wall calendar and postcard. Their dramatic bluffs provide nesting places for Rock Wrens and Prairie Falcons. Pronghorn and Black-tailed Prairie-Dogs are easy to see in this area; lucky observers may even spot a jackrabbit, a Swift Fox, or a Golden Eagle. Mountain Plovers nest in a few of the surrounding prairies and pastures. For a longer, scenic adventure, travel the Pawnee Pioneer Trails, a Colorado Scenic and Historic Byway.

Bear Creek Lake Park
Though overshadowed by Chatfield just to the south, Bear Creek Lake is worth visiting in its own right, especially during migration. Just about any species of waterfowl could show up, and there are usually a few loons present during the fall, along with gulls of various stripes. The best viewing tends to be from Pelican Point. The park also has abundant riparian habitat with a good system of trails along Bear Creek and Turkey Creek; they are most productive during migration, but even in the summer can be worth exploring, with species like Yellow-breasted Chat, Cooper’s Hawk, and even Yellow-billed Cuckoo breeding here. Finally, in winter or during spring snowstorms, the open country of the park is the best place to look for raptors, sparrows, larks, and the occasional longspur or Mountain Bluebird. Note: there is an entrance fee for this property.
Lyons Area
LaVern M. Johnson Park (formerly Meadow Park) in the town of Lyons has nesting White-throated Swifts, Violet-green Swallows, and Canyon Wrens. A pair of Golden Eagles also nests in the cliffs above the park. Just outside town, Apple Valley Road and South Saint Vrain Road run through rural residential areas where the dry hillside brush meets the lush riparian habitat of the river bottoms. Running entirely through private property, these two roads are best birded on foot; be very careful of traffic. Your reward could be dry-country species like Woodhouse’s Scrub-Jay and Bushtit, or riparian birds like Lewis’s Woodpecker (uncommon) and Black-headed Grosbeak. Migrants come through in spring and fall; Pygmy-owls are sometimes seen in winter. Note: there is a parking fee for LaVern M. Johnson Park.
Ireland Reservoir #5
This reservoir can be a great place to see ducks and other waterbirds, at least in spring before the weeds grow tall enough to block the view. A scope is helpful and note that in some years, the reservoir runs dry.
Karval State Wildlife Area
This very remote State Wildlife Area is scenic, with some small bluffs and a medium-sized lake. It is one of the better locations in the county for migrating shorebirds and ducks. Look for Rock Wren, Golden Eagle, Scaled Quail, pronghorn, coyote and jackrabbits. The State Wildlife Area offers free primitive camping.
Riverside Farms
Located outside of the town of Idalia near Bonny Reservoir, this farm and ranch offers rolling shortgrass prairie with sandsage, prairie-dog towns, and the south fork of the Republican River. The river flows year-round and is a draw for local and migrant birds. More than 250 bird species have been recorded in the area. Cardinals can be seen at the western extent of their range along with Eastern Bluebird; Belted Kingfisher, Yellow-rumped Warbler, Marbled Godwit, Wilson’s Snipe, Great Blue Heron, and Osprey are just a few of the other birds you may encounter. Burrowing Owls are prevalent on the uplands along with Ferruginous Hawk, Golden Eagle, and Cassin’s Sparrow. Mule deer and pronghorn are also in the area. Don’t miss the opportunity to experience such rich diversity in a secluded, private setting with your own viewing blind. For more information contact Don, Myrna or Nathan Andrews (970) 354-7487 or northill@plainstel.com.
Wellington State Wildlife Area
This State Wildlife Area is comprised of three units, Wellington, Schware, and Cobb, and offers limited access However, when visiting is permitted, this can be a good place to look for migrants in the junipers and other shrubs, and for roosting Short-eared and Long-eared Owls in winter. The Cobb Lake unit is open year round; its namesake lake sometimes attracts waterfowl and shorebirds. Hunting occurs on the Wellington and Schware units, so be sure to check for seasonal restrictions before visiting these properties.
Gregory Canyon
One of the finest birding areas in Boulder, Gregory Canyon is on the edge of the city, where the foothills begin. The thick riparian tangles here support species, including Warbling Vireo, Gray Catbird, Virginia’s and MacGillivray’s Warblers, and Yellow-breasted Chat. The surrounding pine forest add Lesser Goldfinch, three species of Empidonax flycatcher, Black-headed Grosbeak, and Western Tanager. The cliffs overhead are home to Canyon Wrens and a few pairs of Peregrine and Prairie Falcons. Arrive very early at this popular park in order to secure a parking spot. Note: there is a fee to park at this property.
High Line Canal (Denver Section)
Well-connected to the Denver area bike-trail system, the High Line Canal Trail is, in terms of habitat, probably the best path throughout the city. The portions further south are discussed separately, but the Denver portion makes for a good morning bike ride or walk if you’re staying in the city. The mile-and-a-half stretch of the High Line Canal west of Havana and east of Valentia may be the best birding area along the canal in Denver. Almost continuous large cottonwoods line this stretch, supplemented by adjacent tall trees in many yards with, in some places, good undergrowth tangles. A natural area just southeast of the trail’s junction with Valentia is not open to the public, but can be partially birded from the trail side of the fence.
You can read about author Robert Michael Pyle’s adventures growing up along the High Line Canal in The Thunder Tree: Lessons from an Urban Wildland.
West Pawnee Ranch
Located north of the west section of the Pawnee National Grassland, the Ranch features a variety of habitats including grasslands, riparian, juniper-laden rocky ridges and a wetland/pond complex. Wild Turkeys are common. Golden Eagles have nested on the property and the site is an oasis for many a migrant songbird. In the fall and spring, many surprises could abound. Porcupines and swift foxes can also be seen here.
Lair O’the Bear Park
Just above the little town of Idledale along the gorgeous Bear Creek Canyon, Lair O’the Bear Park has some high-quality riparian habitat along Bear Creek, as well as more typical foothill habitats. The creek itself is among the best places anywhere to see American Dipper, where one is almost always around any time of year. Willows nearby host MacGillivray’s Warbler during the summer months, with the the taller trees also having Yellow-breasted Chat. Both Lazuli and Indigo Buntings have been seen here, along with hybrids. Migrants should be looked for in season, and with the quality of habitat here, you never know what could show up! This park is very popular, so be sure to arrive early.
Hall Ranch Open Space
The trails in this large park near Lyons rise rather steeply onto a forested ridge. On the way up, they run past dry shrubs full of Spotted Towhees, beneath bluffs where Canyon Wrens live. Townsend’s Solitaire and Steller’s Jay are often easy to find and Lazuli Bunting has been spotted here. Watch for rattlesnakes on the trails, and Golden Eagles soaring overhead. Please be aware dogs are not allowed at this property.
Banner Lakes State Wildlife Area
This large wildlife area is a very worthwhile destination; however, it is closed during waterfowl hunting season to everyone except hunters. In addition, the north half of the area is closed from April 1 through July 15 to protect nesting waterfowl. However, the trails south of CO 52 are still accessible during that time, and provide access to several nice marshes, ponds, and thickets. Several species of ducks and other waterbirds nest here, along with several species of raptors, and owls sometimes roost in the thickets. Be sure to check for seasonal restrictions before heading out.
Hugo State Wildlife Area
This remote State Wildlife Area is much like its neighbor, Kinney SWA (Kinney Tract). The several ponds are small, as are the trees below the dam, but they are so isolated that they tend to attract good migrants. Burrowing Owls live in the prairie dog town just west of the entrance, and Mountain Plovers can occasionally be seen. Look also for mule and white-tailed deer, pronghorn, red fox, coyote, cottontail rabbits, jackrabbits, and muskrat. Like at Kinney, you can camp at the Clingingsmith Tract for free.
Bonny Reservoir area
Bonny Reservoir is a large reservoir isolated on the Kansas border. The lake itself is excellent for waterbirds and shorebirds. The abundant riparian groves around the lake can be spectacular for migrants, Red-bellied Woodpecker, and Eastern Bluebird. The grasslands and hedgerows around the periphery of the park are among the best places to look for Bell’s Vireo, Field Sparrow, and Baltimore Oriole in Colorado. Mule and white-tailed deer are common in the area, and you might see jackrabbits, cottontails, beavers, muskrats, weasels, opossums, and thirteen-lined ground-squirrels.
Hamilton Reservoir
Hamilton Reservoir was created as a cooling lagoon for Platte River Power Authority’s Rawhide Energy Station. Because of the warm water coming in from the power plant, it stays open even in the coldest winter weather. During cold spells when all the other water in the region is frozen, ducks, geese, grebes and other waterbirds can congregate here in huge numbers. The power company maintains a visitor viewing area on the south side of the reservoir where birds are easily seen with a scope. The utility also maintains an area of native prairie to the west that can be viewed from the entrance road. Lark Buntings, Grasshopper Sparrows, Common Nighthawks, and other prairie birds can often be found here in summer. If you are lucky, you may even see part of the bison herd that Platte River maintains on the land.
Boulder Creek (downtown section)
A paved walking and biking trail follows Boulder Creek through much of the city of Boulder. Along the way, it is often canopied by mature cottonwoods and willows, making it a good birding destination. Birds that breed here include White-breasted Nuthatch, Warbling Vireo, and the rare Eastern Screech-Owl. Migrants can pass through in good numbers in spring and fall and American Dipper can be found along the creek, especially in winter. Be sure to stop for a refreshment on one of the many outdoor patios in downtown Boulder, where you can enjoy birding with a cold brew!
O’Fallon Mountain Park
Not far upriver from Lair O’the Bear Park along Bear Creek, the habitat at O’Fallon Mountain Park has a higher-elevation flavor, with more ponderosa and mixed-conifer woodland and fewer riparian areas. There are some nice large willow trees along the river, and the overall mix of habitats results in a variety of species of both higher and lower elevations. The ponderosa component offers up the chance at Williamson’s Sapsucker, Pygmy Nuthatch, and Western Bluebird, while the mixed conifers can have Dusky and Hammond’s Flycatchers, Ruby-crowned Kinglet, and Brown Creeper, among others. Along the creek, check for Cordilleran Flycatcher and American Dipper, both fairly common here during the summer months. Be sure to stop at nearby Mount Falcon Park for more viewing opportunities.
Heil Valley Ranch
Several trails on this 5,000 acre property wind through ponderosa pine forests and foothill meadows. The trails are very popular with hikers and mountain bikers, but with luck, especially first thing in the morning, you could run into Wild Turkeys or Dusky Grouse. Easier to find species include Western Tanager, Pygmy Nuthatch, and Black-headed Grosbeak, not to mention several species of squirrels. Please be aware dogs are not allowed at this property.
Prospect Reservoir
This large private lake can only be scanned from one spot: the pullout in front of the gun club access gate near the southeast corner of the reservoir. From this vantage point, a variety of waterbirds can be seen (especially with a scope), including breeding Western and Eared Grebes and many duck species in winter. The marsh at the northeast corner of the reservoir is a breeding site for Yellow-headed Blackbird, Great-tailed Grackle, and Marsh Wren. Grasshopper Sparrows nest in some of the fields to the east of the reservoir.
Kinney State Wildlife Area (Kinney Tract)
Small and secluded, Kinney State Wildlife Area can be very attractive to birds. The trees right around the parking lot and the Russian-Olives along the east shore provide shade and can be good for migrating flycatchers, warblers and sparrows. A stand of willows on the southwest shore of the lake is worth checking too. Marsh birds congregate in the cattails at the far north end of the lake, and you might see mule and white-tailed deer, pronghorn, rabbits, red fox, coyotes, snakes and other reptiles. You can camp for free in this beautiful location.
Soapstone Prairie Natural Area
This beautiful, remote natural area on the Wyoming border conserves an enormous area of native grasslands and brushy draws. Soapstone is an important part of the Laramie Foothills Mountains to Plains Project, a partnered conservation effort to create a corridor of protected lands connecting the mountains to the plains. Because of the extensive landscape, it is possible to hike the trails here for hours without seeing another person. Lark Buntings, Grasshopper Sparrows, and other prairie birds can be seen right along the entrance road in summer, as can pronghorn and jackrabbits. A herd of bison roams a 1000-acre enclosure here, and can sometimes be seen from the road. Mountain Plovers and Burrowing Owls breed on the property, but they are difficult to see because the trail into the best habitat is closed April 1 – July 15 to protect them from disturbance.
A hike up into the mountain mahogany scrub could produce Spotted Towhee, Brown Thrasher, and with luck, even Virginia’s Warbler. An exciting comeback story – the endangered black-footed ferret was reintroduced back to this property and once again hunts on the open prairie. The trails access remote backcountry, and hikers should be well prepared to deal alone with potential emergencies. This natural area is closed December – February and dogs are not allowed.
Wonderland Lake
Nestled in a scenic neighborhood in north Boulder, this area offers open space, short and easy trails, and water access that attracts a diversity of waterfowl. Trails leading away from the lake cross foothills grassland and tallgrass prairie stands, providing plenty of habitat for a variety of birds.
Evergreen Area
Another of the charming foothill towns outside of Denver, Evergreen is a good place to vacation away from the city. Due to its close proximity to Denver, this is a very high use area by birders, anglers, dog walkers, runners, and visitors in general. But it’s also a decent birding location in its own right. The best spot is undoubtedly Evergreen Lake, surrounded by a park with good walking trails that provide easy access. During migration, most any waterfowl species could show up, and Barrow’s Goldeneye has occasionally been found here. A small marsh at the edges of the lake may have rails or Marsh Wren, and riparian grove migrants in season. Be sure to stop by the Evergreen Audubon & Nature Center located in the historic warming hut on Evergreen Lake. There are several other parks in the general area, most of which are covered in ponderosa woodland with a mix of foothills scrub; you may want to check out Jefferson County Open Space’s website for ideas. The best option is probably Alderfer/Three Sisters Park; look for Pygmy Nuthatch, Clark’s Nutcracker, Western and Mountain Bluebird, and Red Crossbill, among other possibilities. Mammals such as Elk, Mule Deer, and Abert’s Squirrel all occur in this area, and could be found nearly anywhere.
NOTE: Elk commonly use the lake, trails, parking areas, and the vicinity around them year-round, but especially during calving and the rut (mating season). Please do not approach elk and keep dogs on a leash at all times. They may appear to be tame, but there is history of conflict and injuries associated with getting too close.
Hugo
In the town of Hugo you may want to make your way to the southeast corner and look for the town’s Wild Turkeys. They can be found in people’s yards and in the middle of the streets. Migrants can also show up in the city park and in neighborhoods with mature trees. On the surrounding plains you have a good chance of spotting pronghorn, coyote and jackrabbits.
Lower Poudre Canyon/Gateway Natural Area
As Colorado Highway 14 follows the Cache la Poudre River west up into the mountains, it passes several trailheads and parks along the way that provide access to the river and adjacent habitats. Gateway Natural Area just may be the best of these. Look for American Dippers bobbing on the rocks in the middle of the river, and Common Mergansers floating on the water. Also watch along the highway for bighorn sheep and mule deer that can sometimes be seen from the road. The 2020 fire has radically changes some areas of the canyon, effecting birding. But, near the River, in most areas, there are still some trees.
Betasso Preserve
This popular park west of Boulder, with miles of trail through meadows and pine savannahs, is a great place to find specialty species of the ponderosa belt, including Mountain and Western Bluebirds, Pygmy Nuthatch, Wild Turkey, and the tufted-eared Abert’s squirrel.
South Valley Park
Not far from the famed Red Rocks, the topography at this foothills park is very reminiscent of its more well-known neighbor. Numerous rock outcroppings, tons of thick foothills scrub, and some good riparian habitat along Deer Creek offer a good variety of species to look for most of the year. Keep an eye out especially for White-throated Swift, Canyon and Rock Wrens, Golden Eagle, and Prairie Falcon nesting on the cliffs; Spotted and Green-tailed Towhees in the scrub; and migrants in the riparian habitat. American Dipper can sometimes be found along Deer Creek, best searched for in early spring and fall through winter. In general, the colder months tend to be quiet, though flocks of sparrows may be hiding in the scrub. Visit Jefferson County Open Space’s website if you’d like to stop by one of the other parks they manage in this area.
Laramie River Road
This remote road runs about 20 miles from high-elevation spruce-fir forest down to open sagebrush and wet meadows, through several different forest types, with a tremendous diversity of birds and other wildlife in between, from marmots to elk. Much of the land along the road is public, and there are several National Forest campgrounds and primitive campsites. With luck, Veery can be heard in some areas of dense willows. The burn scar from the 2020 fires devestated the upper hills in the upper valley, but the lower areas are good and the meadows are good for birding.
Walker Ranch Open Space
This open space in the foothills above Boulder is a good place to find low-elevation mountain species like Pygmy Nuthatch, Mountain Chickadee, Mountain Bluebird, and both sapsuckers. In winter, you can find flocks of Dark-eyed Juncos, including all five Colorado subspecies. Keep your eye to the sky, as Golden Eagles sometimes fly over the mountain. Black Bears and Mountain Lions are also found in this area. Be sure to stop by the Flagstaff Nature Center at the summit of Flagstaff Mountain Road.
Turkey Creek Park
Located near the tourist attraction Tiny Town (a good place to bring kids if you have the family along), this park has a nice mix of ponderosa and mixed conifer woodlands, along with smaller meadows and areas of foothills scrub. The lower parts of the trail are excellent for Red-naped Sapsucker and Wild Turkey; with luck, Dusky Grouse could be found throughout the area. More common montane species such as Pygmy and Red-breasted Nuthatches, Red Crossbill, and Cordilleran Flycatcher are also present. In the more open areas, check for Black-billed Magpie and Mountain Bluebird. The park is well-known for its uncommon butterfly species you might find during spring and summer, including Hoary and Moss’s Elfins, and Indra Swallowtail.
Cameron Pass and upper Poudre Canyon
The beautiful spruce-fir forest here is home to high-mountain birds such as Pine Grosbeak, Gray Jay, American Three-toed Woodpecker, Cassin’s Finch, and Red Crossbill. Occasionally, White-winged Crossbills can be seen near the top of the road. The area around Cameron Pass is famous as a site for the highly elusive Boreal Owl, which is best heard late at night, between February and April, within 2 miles of the pass. Also watch for bighorn sheep crossing the road in daylight, and porcupines crossing the road at night. Moose are in the area, seen usually in meadows with creeks running through them. The 2020 fire scorched some areas, but left other areas untouched.
Conifer Area
Conifer is a beautiful little foothill town just west of Denver, and makes a perfect base for exploring the lower montane habitats found in the area, including all the amenities needed for a trip. There are a number of parks near Conifer that are quite similar to each other, and visiting any of them would probably net the target species. One of the best of the bunch is Flying J Ranch Open Space, where you can find abundant, high-quality mixed-conifer woodlands, interspersed with aspen groves, large meadows, and even a small pond. Look here for Pygmy Nuthatch, Williamson’s Sapsucker, migrating sparrow flocks in the meadows that can include Brewer’s, Lincoln’s, and White-crowned Sparrows, and all the usual suspects for this elevation and habitat. Beaver Ranch Open Space, just south of Conifer, has all of the same habitats, as well as a nice willow-lined creek near the entrance. Look here for the same species, as well as hummingbirds (including Rufous and Calliope in late summer) visiting thistles along the entrance road. Newton Park, just across the road to the north, is made up of three picnic sites that require advance reservation to use. However, you can walk into the park from Beaver Ranch. At Meyer Ranch Open Space, just northeast of Conifer, there is an extensive system of trails guiding you through some nice habitat, where you can expect to find the same species as at Flying J.
Reynolds Open Space Park
This open space park contains some quality ponderosa and mixed-conifer woodland, along with a nice trail system, offers a nice variety of montane species. In the ponderosa dominated areas, look for Pygmy Nuthatch and Williamson’s Sapsucker, while the mixed woodland could have Red-naped Sapsucker, American Three-toed Woodpecker, Hammond’s Flycatcher, and Merriam’s turkeys in the spring. Steller’s Jays are common throughout, and a nighttime visit may turn up a Northern Saw-whet Owl, best searched for during the spring months.
Staunton State Park
Near the town of Pine, Staunton is Colorado’s newest state park, which opened to the public in 2013. Situated southeast of Mount Evans, elevations in the park range from 8,000 to 10,000 feet. Large granitic domes, such as the Lion’s Head, visually dominate the park, and wetland habitats along the park’s many streams divide the montane forests below. Forested areas provide excellent opportunities to view Williamson’s and Red-naped Sapsucker, American Three-toed Woodpecker, Hammond’s Flycatcher, and Golden-crowned and Ruby-crowned Kinglet. Look for singing Vesper and Savannah Sparrows, along with other grassland species, in the montane grasslands across the park. Rocky outcrops and cliffs are habitat for White-throated Swift, falcons, and hawks. Several wetland birds such as Great Blue Heron and Belted Kingfisher can be seen at the park, and Lincoln’s Sparrow and Olive-sided Flycatcher are found along the stream corridors. Celebrate the park’s mascot, the yellow-bellied marmot, at the annual Marmot Fest in June. You might even catch a glimpse of these chubby critters sunning themselves on rock outcroppings from spring to fall. A State Parks pass is required for entry.
