gull . Its generic placement is disputed; some authors treat it as the sole species in the genus "Xema" as "Xema sabini",del Hoyo, J., et al. (1998). "Handbook of the Birds of the World" 3: 621.

It migrates south in autumn; most of the population winters at sea in thePacific off westernSouth America in the cold waters of theHumboldt Current , whileGreenland and eastern Canadianbird s cross the Atlantic by way of the westernmost fringes ofEurope to winter off southwestAfrica in the cold waters of theBenguela Current . Occasionally individual Sabine's Gulls can be seen off other coasts such as the northeasternUnited States or further east in Europe, typically following autumn storms.

The adult had a pale grey back and wing coverts, black primary flight feathers and white secondaries. The white tail is forked. The male's hood darkens during breeding season. Their bills are black with a yellow tip. Young birds have a similar tricoloured wing pattern, but the grey is replaced by brown, and the tail has a black terminal band. The juveniles take two years to attain full adult plumage. They have a very high-pitched and squeaking call.
The Sabine's Gull breeds in colonies on coasts and
tundra , laying two or three spotted olive-brown eggs in a ground nest lined with grass. It is very pelagic outside the breeding season. It takes a wide variety of mainly animal food, and will eat any suitable small prey. It also steals eggs from nesting colonies ofArctic Tern s.This bird was named after the Irish scientist Sir
Edward Sabine by his brother Joseph Sabine.References
