Glaucous-winged x Western Gull adult, Janaury 02 2012, Ocean Shores, WA. Picture: Amar Ayyash.

Two adults.

Although Glaucous-winged Gulls are year-round residents in Western Washington, it is not always obvious which birds are "pure". Many fit the Western profile but showed some combination of cloudy head markings, barring on the neck, pale eyes, paler bill and/or paler upperparts like this bird in the first image.
