Visit to Rocky Mountain Arsenal, Adams County

This morning Rebecca and I went to Rocky Mountain Arsenal hoping to find some of the birds the Jerry Petrosky found on 8/23. The Dunlin that Dave Rhodes found on 8/25 was found in a closed area with no public access.

The only uncommon bird we found was a Cassin's Vireo north of 6th Avenue in the thick riparian area just west of the irrigation ditch along 6th (ditch is just west of area where 6th changes from paved road to gravel).

At least eight Western Wood-pewees, two Loggerhead Shrikes and one Bullock's Oriole were counted.  Raptors included Red-tailed Hawks, Swainson's Hawks, a Ferruginous Hawk and a Great Horned Owl.
