Search for Greenlee Preserve Sparrows

January 23, 2008

Roger Danka and I drove up to Lafayette and searched for the Swamp and White-throated Sparrows reported by Ted Floyd at Greenlee Preserve (Boulder County). I stuck out for the second time.

On the way to the South Platte River and 88th avenue we drove by 104th avenue and Sheridan (Jefferson). Historically, a partial albino Red-tailed Hawk has been hanging out here for five or six years. I also missed it for the second time in a row.

At the S. Platte River (Adams) we hiked 1 mile upstream to the green and white tower. The male Barrow's Goldeneye was about 20 yards north (downstream) of the tower. Winds were quite strong 15-20 mph range and temperatures in the high 20s. That encouraged us to turn around and head toward Cherry Creek Reservoir.

Few birds were again moving about Cherry Creek Reservoir. However, we did relocate the Northern Shrike at the southwest corner of the shooting range.

We looked of Short-eared Owls along the DIA Owl Loop; without success. We did find 2 Northern Harriers, 1 Ferruginous Hawk, and 1 Red-tailed Hawk before sunset. The huge numbers of Horned Larks have either moved on or are far enough from the main road to escape scrutiny. Not much else was seen after sunset.
