Adams and Arapahoe County Birding

December 11, 2010

Richard Stevens:

Bryan Ehlmann, Jacob Washburn and I walked the east side of the South Platte River from 88th Avenue at Colorado Blvd to Highway 224 and back.

The male Barrow's Goldeneye was first observed on the Platte River, just south of the green & white tower. Later he joined a female Barrow's Goldeneye on Tani Reservoir. A Northern Shrike was on the western fence of Tani Reservoir.

Farther south, we found a Harris's Sparrow in the trees along the Platte River, just north of the 74th avenue pond. A Lincoln's Sparrow was in the trees along the Platte River near the spillway.

The only sparrows found along Clear Creek, east of the Platte River were 9 American Tree Sparrows and 2 Song Sparrows.

We stopped briefly at Rocky Mountain Arsenal (Adams). No uncommon waterfowl were on Lake Ladora. No unusual sparrows around Mary's Lake. In fact, not much of anything was moving around.

We were informed of details of a Ross's Gull at Lake Ladora (Adams) on 12/4/2010.

Later we drove over to Cherry Creek Reservoir (Arapahoe County). Again, I enjoyed a 7 Gull species day, which included: Iceland Gull, Mew Gull, Lesser Black-backed Gull, Thayer's Gull, California Gull, Herring Gull, & Ring-billed Gulls.
