This species breeds in northern Eurasia and North America with significant populations south to the north of Scotland. It nests on dry tundra, higher peaks and islands, with a maximum of four olive-brown eggs. This bird eats rodents, small birds and insects, but also robs gulls and terns catch.
Identification is performed by long-tailed Skua similarities and Pomarine Jaeger, and the existence of three types of stains complicated. As small to Jaeger parasitic skua weighs 41-48 cm (16-19 inches) long, 107-125 cm (42-49 inches) and 300-650 g scale (0.66 to 1.4 pounds). Adult white morph has a back light brown, mostly white undersides of the wings and dark primary feathers with a "flash".
Adults are dark brown dark morph and intermediate stages birds are dark with a little paler underside, head and neck. All samples have flashing white wings. Juveniles are more problematic, and are difficult to separate long tail Jaegers.
