Range Extent Comments
Circumpolar. BREEDS: in arctic of Alaska, Canada and Greenland; in Old World from Jan Mayen, Spitsbergen, northern Eurasia. NONBREEDING: at sea in Atlantic and Pacific Oceans, more commonly in cold southern localities (Godfrey 1966) such as off Argentina and Chile.
Ecology & Habitat

Habitat

Nonbreeding: pelagic, casually along seacoasts and on inland waters (AOU 1983). Nests in open or alpine tundra, flats with sparse vegetation, and moorlands (AOU 1983). Most often in well-drained upland areas, also in dry tundra in low-lying areas; nest usually on mound or hummock (Johnson and Herter 1989). Nests on the ground in a depression, into which it may scrape small amounts of grass, leaves or moss. May nest among rocks.

Ecology

Pairs defend large territories, but often hunt over an area larger than the territory; in northern Sweden, hunted up to 2.7 kilometers from nuest, usually less than 700 meters (Andersson 1971).

Reproduction

Eggs are laid mainly mid- to late June. Both adults, in turn, incubate 2, sometimes 1-3, eggs for 23-25 days. Hatching was recorded in second week of July on Ellesmere Island. Young are tended by both parents, fledge in 22-28 days, attended by adults for 10-21 days after fledging. Second-hatched chick in most broods usually does not survive (Johnson and Herter 1989).
