Crisp small gull with very limited range; breeds on rocky cliffs on islands in the Bering Sea, from Alaska to Russia; winters on open ocean. Size and plumage most similar to Black-legged Kittiwake, but back is darker gray, yellow bill is shorter, legs are shorter and bright red, and underwing is darker gray. Nonbreeding birds have a dark smudge around eye and a thin gray ear patch. Young birds are similar to nonbreeding adults but with black bill, duller legs, and more contrasting wing pattern.

Larger than a Bonaparte’s Gull and slightly smaller than a Black-legged Kittiwake.
