Walden Ponds Wildlife Habitat and Sawhill Ponds

Aliases: Sawhill Ponds, Cottonwood Marsh

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.
