18. Audubon Center at Chatfield, Littleton, Colorado

Rich habitat along the South Platte River just southwest of Denver boasts over 350 species.

The South Platte River flows out of the foothills southwest of Denver into rich riparian habitat. For 40 years, I’ve found the stream bottom inspiring, the birds intriguing, the bird behavior absorbing.

April and May draw migrating landbirds — warblers, flycatchers, tanagers, buntings. The Platte’s riparian tangles have produced four first state records (Thick-billed Kingbird, Blue-winged and Prairie Warblers, and Harris’s Hawk). Breeders abound. On cloudy, rainy, spring days, hundreds of swallows throng the river and gravel pits — five or six species.

On May 11, 2006, we counted 164 Yellow Warblers and 85 House Wrens. When I walk east from the Audubon Center to the river cottonwoods, I can sometimes pick out an American Redstart’s sibilant song. Say’s Phoebes nest on a nature center building, and American Dippers breed along the river (March to June) — look under the Waterton Road bridge.

In fall I look for migrating White-crowned Sparrows that lurk in the yellow-topped rabbit brush, and for Song Sparrows that filter into the brushy streamsides. In winter, the river teems with dippers, kingfishers, and birds of prey. Once we watched a Bald Eagle fly over a mile to take a prairie dog from a Ferruginous Hawk that had stolen it from a Red-tailed Hawk. Earlier, we had had front-row seats as the Red-tail did its hunting. — Hugh Kingery
