Like the Bols, I too visited Horseshoe Lake , although later in the day. I found hundreds of gulls in the southwest corner of the lake, viewed from the Monroe St. on the west side. When I arrived, some gulls were leaving, including an adult “black-backed” gull and a young “white-winged gull”. Among the gulls that stayed, an adult Lesser Black-backed Gull, an adult Thayer’s Gull and a young Thayer’s Gull were harassing a flock of 27 Common Goldeneye. In this flock was an adult male Long-tailed Duck in winter plumage.
I followed these gulls as they flew off to the southwest to a roost at the south side of Lake Loveland, where over 500 gulls were on the ice shelf at dusk. Among these were two young Thayer’s Gulls and 4 Lesser Black-backed Gulls (3 adults). Many other gulls continued flying southwest towards Carter Lake.
