The "Glaucous Gull" is a large and powerful gull, very pale in all plumages, with no black markings. The term glaucous describes its colouration. This is one of the most predatory of gulls; it captures and eats auks, plovers, small ducks, songbirds, lemmings and fish, and also scavenges though garbage.
The first winter, immatures are pale grey with a pink bill and legs.
The "Glaucous Gull" breeds, colonially or singly, on coasts and cliffs in the Arctic regions of the northern hemisphere.
Calls or song.
This gull speaks in a hoarse croak, and his scream is like the laugh of the Herring Gull.
Population and distribution.
Rarely seen south of Canada, when it does visit the United States in winter, it inhabits the shores of lakes and rivers, as well as the seacoast areas of Washington, Oregon, the Great Lakes and the eastern states south to Virginia.
The female gull lays three light brown eggs, with dark brown splotches, on a cliff in a nest of moss and grass.
