All birds in winter plumage: Large, long-winged, deep-bellied gulls. Fairly long and thick bills, with obvious gonydeal angle. Heads were strongly sloping and relatively flat-crowned. Adult birds: White head and neck with extensive dark streaking; yellow bills with red gonydeal spot; pale yellow iris framed by yellow-orange orbital ring; pale gray back and wings; blackish primaries with white tips; white tail and rump; pink legs. Third-Winter birds: At least three individuals. Similar to adult birds, but noted more extensive mottling on head and neck, with dark smudging around eye; bill pinkish-gray with dark band; also observed some brown present in wing coverts, as well as traces of a dark tail band; pink legs. New for the WBL!
