The Washington Gap Analysis Project created breeding bird maps only. The non-breeding birds (e.g., wintering, pelagic (coastal), and birds expanding their ranges) are represented only by NatureMapping sightings.

The Glaucous Gull winters along the coasts all the way from the Pribilof Islands and Alaska, along western Canada, Washington, Oregon and northern California. Breeding takes place on Arctic coasts and islands from Alaska and as far as Greenland. Rare winter resident in Washington. Immature birds predominate near coasts, adults more frequent in eastern Washington.
