Aurora Reservoir Gulls

December 24, 2012

Richard Stevens:

Bryan Ehlmann, Jerry Petrosky and I relocated a Lesser Black-backed Gull and Thayer's Gull at Aurora Reservoir. No Glaucous Gull was found.

We watched the Barr Lake (Adams County) feeders for 2 hours. The Fox Sparrow did not appear. With misses for an hour each on Saturday and Sunday, we will probably not go back unless someone else finds the sparrow (gone?).

White-crowned Sparrow numbers (7) and American Tree Sparrow numbers (6) were up yesterday. One rufous crowned sparrow appeared bigger than the American Tree Sparrows. It turned out to be a Chipping Sparrow. Clear breast, no spot, and no rufous color on sides of breast.

No owls along the DIA Owl Loop, other raptor numbers were up, perhaps wanting to eat before last night's snowstorm.
