Ichthyaetus ichthyaetus (Great Black-headed Gull; Pallas's Gull)

Synonyms: Chroicocephalus kittlitzii; Larus ichthyaetus (homotypic)

Wikipedia Abstract

The Pallas's gull or great black-headed gull (Ichthyaetus ichthyaetus) is a large gull. As is the case with many gulls, it has traditionally been placed in the genus Larus. The scientific name is from Ancient Greek. Ichthyaetus is from ikhthus, "fish", and aetos, "eagle". 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. These birds are predatory, taking fish, crustaceans, insects and even small mammals.
