Glaucous-winged Gulls are distinguished from almost all other gulls by the lack of black in the wing tips. Only the Glaucous Gull is similar, but it is paler overall. Glaucous-winged Gulls breed along coastal areas in western Alaska, the Aleutian Islands, western Canada, and the states of Washington and Oregon in the US. They spend their winter in all but the far northern regions of their breeding range and also spread south to southern California and Baja California.

Great Black-backed Gulls occur in eastern North America and most of Europe. In North America it is strictly coastal, and is the largest gull found along the eastern shores of Canada and the US. Although it easily dominates the Herring Gulls with which it normally associates, it is wary of people and will fly away before the Herring Gulls when a mixed flock is approached. This one, looking a little bored with it all, was photographed at Manasquan Inlet, New Jersey, USA. Photo taken with a Nikkor 300mm ED f4.5 lens on Kodachrome 64 film. (Date: December 1983)
