Fossil Creek Reservoir Natural Area

Designated as an “Important Bird Area” by the National Audubon Society, this is one of the best birding locations in the area. Huge numbers of geese often stage here in late fall, including thousands of Cackling Geese, with some Snow, Ross’s, and Greater White-fronted Geese usually mixed in. Sometimes the geese even stay all winter! Ducks, Grebes, Loons, and Gulls can also be seen here between fall and spring, along with Bald Eagles. The cottonwoods around the lake attract breeding Orioles, and the Prairie-dog towns attract raptors, occasionally including  Ferruginous Hawk and Golden Eagle. A Bald Eagle nest located on the opposite side of the lake can be viewed from the gazebo east of the Visitor Center. Please note pets are not allowed at this property. A nearby adjacent site 3/4 of a mile west from the Natural Area entrance is a small pond on the south side of the road that often has many water birds on it.  Be careful, as there is heavy traffic and no pull-off except a small space on the west side of the pond.
