Cherry Creek and Walk Along Sand Creek

September 19, 2008

Richard Stevens:

Gary Weston and I returned to Cherry Creek Reservoir (Arapahoe). Again we found the Long-tailed Jaeger and one or two Common Terns flying around the lake. Just east of the path down to the Bird Platform, a Cassin's Vireo accompanied a loose flock of birds which included 9 Black-capped Chickadees, 2 Orange-crowned Warblers, and a few Chipping Sparrows. They were moving toward the inlet canal at the Cottonwood Creek Loop when we left.

A check of Bluff Lake Natural Area (Denver) turned up almost no birds. So we decided to search the many willows along the bike path from Quebec Street to 56th Avenue. The habitat always appeared to be quite good for migrating birds and few birders report searching there.

We enjoyed good success. Two flocks of birds were found far enough apart that we knew they were different birds. The first flock about 800 yards northwest of Quebec Street included 2 Townsend's Warblers and a Plumbeous Vireo. Toward the north end of our trek we found another 2 Townsend's Warblers. In between we noticed 2 Northern Waterthrushes separately walking along the edge of Sand Creek. We also observed 3 House Wrens, 2 Double-crested Cormorants, Chipping Sparrows, 4 Brewer's Sparrows, 6 Song Sparrows, and a Clay-colored Sparrow.
