Xema sabini, commonly known as Sabine's Gull, is a small, graceful seabird found in the Arctic regions during breeding season and migrates to the tropical Atlantic and Pacific oceans in winter. Distinguished by its forked tail and striking black, white, and gray plumage, it is known for its agile flight and feeding on insects, crustaceans, and small fish.

Xema sabini, commonly known as Sabine's Gull, is native to the Arctic regions of North America and Eurasia. It breeds in the high Arctic, with its range extending from northern Greenland, across northern Canada, to Alaska and Siberia.

Sabine's Gull typically inhabits coastal tundra regions during the breeding season. These areas are characterized by cold temperatures, with short summers and long, harsh winters. The tundra environment includes wetlands, marshes, and coastal lagoons, which provide nesting sites and abundant food resources.

During the breeding season, Sabine's Gull relies on the abundant invertebrate and small fish populations found in the tundra's wetlands and coastal areas. It is adapted to foraging in these regions, often seen picking food from the water's surface. Outside the breeding season, Sabine's Gull migrates to the open ocean, particularly in the North Atlantic and Pacific Oceans, where it continues its pelagic lifestyle, feeding on marine invertebrates and small fish.
