The Armenian gull (Larus armenicus) is a large gull found in the Caucasus and the Middle East. It was formerly classified as a subspecies of the European herring gull (L. argentatus), but is now generally considered to be a separate species, although BirdLife International lumps it with the yellow-legged gull (L. michahellis).
The Armenian gull is a fairly large gull species, though it is on average the smallest of the "herring gull" complex. They are superficially similar to yellow-legged gulls but are slightly smaller with a slightly darker grey back and dark eyes. The area of black on the wingtips is more extensive with smaller white spots. The bill is short with a distinctive black band just before the tip. First-winter birds are mainly brown. They have a whitish rump, pale inner primary feathers, and a narrow, sharply-defined black band on the tail. Although their ranges do not overlap, with its darkish mantle, both black and red near the tip of its bill and a dark eye, the Armenian gull bears a remarkable resemblance to the California gull (L. californicus) of North America.
