The parasitic jaeger or arctic skua (Stercorarius parasiticus), also known as the parasitic skua or arctic jaeger, is a seabird in the skua family Stercorariidae. It is a migratory species breeding in Northern Fennoscandia, Scotland, Iceland, Greenland, Northern Canada, Alaska, and Siberia and wintering across the southern hemisphere. Kleptoparasitism is a major source of food for this species during migration and winter, and is where the name is derived from. Wikipedia →
