Which bird is pictured below?

Pallas's gull or great black-headed gull is a large gull. As is the case with many gulls, it has traditionally been placed in the genus "Larus". This species breeds in colonies in marshes and islands from southern Russia to Mongolia. It is migratory, wintering in the eastern Mediterranean, Arabia and India. This gull nests on the ground, laying between two and four eggs.

This is a very large gull, being easily the world's largest black-headed gull and the third largest species of gull in the world, after the great black-backed gull and the glaucous gull. It measures 55–72 cm (22–28 in) in length with a 142 to 170 cm (56 to 67 in) wingspan.
