Adams, Denver and Arapahoe County Birding

May 3, 2010

Richard Stevens:

Jerry Petrosky and I returned to the eastern side of the Rocky Mountain Arsenal today. Winds were mild, temperatures on the cool side (high 50s).

We observed 11 Burrowing Owls during our hike (3 inside the arsenal, Adams County; 8 outside, Denver County).

A Northern Mockingbird was again found about 1.1 miles north of 56th avenue. Last year a pair nested in the same general area. I hope that a mate will show up for this one!

Later we looked for owls along the DIA Owl Loop. No Short-eared Owls today (we believe we know the area of a nesting pair). We did find 15 Burrowing Owls along the route.

After leaving Jerry, I drove over to Cherry Creek Reservoir (Arapahoe). One of the Short-billed Dowitchers was walking around the new wetlands area, east of the model airplane field.

A Willet and Bonaparte's Gull were still at the southeast sand spit!
