[cobirds] Prewitt Reservoir

Several of us (David Dowell, Dick Schottler, Kathy Mihm-Dunning, Charlie
Lawrence, Dean Shoup, Nana Torres, Alec Hopping and I) went up to northeast
Colorado today. A BEAUTIFUL day on the plains with the morning breeze
abating by late morning.

One of our stops was Prewitt Reservoir. The reservoir is still 70%+ frozen
(thinly), but the gulls were many. There is a shad die-off that the gulls
are picking out of the ice (the shad died and were frozen into the ice
during the latest freeze we had last week).

Today we found:
Herring Gull
Ring-billed Gull
Lesser Black-backed Gull - 1 adult
Iceland Gull - 1 adult
Glaucous Gull - 1 (likely 2) 1st winter birds
Glaucous-winged Gull - 1 - 1st winter - Possibly a hybrid, but mostly(?)
Glaucous-winged Gull?

~900 Greater White-fronted Goose at the small pond on US6 at Washington
County Road R.

North Sterling Reservoir (Logan County) was almost completely open with 99
Bald Eagles present and a number of American White Pelicans...as well as
about 15,000+ Snow/Ross's Goose (seen at close range from the south boat
launch).

Jumbo Reservoir still completely frozen...but not for long! :-)
