Large 1st cycle gull on muddy island off lookout point. Neatly checkered across most of wings, which were darker brown than typical of GWGU. Primaries brown with pale edging. Lower scapulars (retained) mostly dark brown centered with pale edging, replaced upper scapulars a mix of pale gray and white. Slim bill without much gonydeal expansion favors this combo over Olympic. Very white head. Larger than Westerns, and did not have the "cutenesss" of a Thayer's. Photos to add.
