    Food Comments
    In Arctic an important predator of lemmings; also predator of young alcids, ducks, and gulls. Feeds on fishes, mollusks, crustaceans and seabird eggs. Preys heavily on eggs and chicks, especially those of waterfowl, in breeding season (Johnson and Herter 1989). Large numbers may stop to feed along barrier islands, at whale carcasses, and at dumps during fall movements (Johnson and Herter 1989).
    Reproduction Comments
    Breeding begins late May to early June (Harrison 1978); egg laying occurs mainly mid- to late June in Beaufort Sea area (Johnson and Herter 1989). Both sexes incubate 2-3 eggs for 27-28 days (Terres 1980). Hatching begins in second week of July in Beaufort Sea area. Semi-precocial young are tended by both parents, fledge at 45-50 days, may be accompanied by adults into mid-September. Often nests in colonies, but may nest singly.
