Armenische Möwe

Bestimmung

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 52 to 62 cm (20 to 24 in), from 120 to 145 cm (47 to 57 in) across the wings, and weighs from 600 to 960 g (1.32 to 2.12 lb). Among standard measurements, its wing chord is 38.5 to 45.8 cm (15.2 to 18.0 in), its bill is 4.1 to 5.6 cm (1.6 to 2.2 in) and its tarsus is 5.7 to 6.4 cm (2.2 to 2.5 in). 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.
