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).

Description

The Armenian gull is a fairly large gull species, though it is on average the smallest of the "herring gull" complex. It can range from Шаблон:Convert, from Шаблон:Convert across the wings, and weighs from Шаблон:Convert. Among standard measurements, its wing chord is Шаблон:Convert, its bill is Шаблон:Convert and its tarsus is Шаблон:Convert.[1] 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.

Distribution and habitat

The Armenian gull nests beside mountain lakes in Georgia, Armenia, Turkey, and western Iran. The largest colonies are at Lake Sevan and Lake Arpi in Armenia. It is a partial migrant, with many birds wintering on the coasts of Turkey, Lebanon, and Israel. Smaller numbers reach Cyprus, Egypt, and the Persian Gulf.

Breeding

The nest is a mound of vegetation built on the ground on an island or the lakeshore. Three eggs are laid, mainly in late April. The nesting colonies are very dense with nests close together and territorial conflicts are common.
