Afternoon At Jackson Reservoir

February 10, 2013

Richard Stevens:

Bryan Ehlmann and I stopped at Jackson Reservoir (Morgan County) today.  Winds were not as strong as yesterday, 8-10 mph, gusts to 16 mph; temperatures never reached 40 degrees.

Long-eared Owls can still be found in the western Campgrounds.  Two Yellow-rumped Warblers fluttered about the trees around the Visitor's Center.  No uncommon sparrows were found today.

Highlights came from a group of gulls.  A Lesser Black-backed Gull stood out among the light mantled gulls.  A quite whitish Gull appeared to be a possible Iceland Gull (Kumlien's).  See February's "Colorado Field Notes" for our views on the Iceland Gull/Thayer's Gull taxa.

Two Great-tailed Grackles were around the house east of the southern parking area below the dam.

Misses: No Varied Thrushes among 100+ American Robins.  No uncommon sparrows.  Eastern Screech-Owl did not come out of its hole.
