About These Birds
Great Skua
Great Skua, 50–58 cm, wingspan 125–140 cm, is a powerful pirate of the North Atlantic, breeding in Iceland, Faroe Islands, and Scotland. Dark brown with white wing flashes. Attacks gannets and kittiwakes to steal fish; also kills other seabirds outright. Winters pelagically in the Atlantic.
Pomarine Jaeger
Pomarine Jaeger, 46–51 cm plus twisted spoon-shaped central tail feathers, is the largest of the three small jaegers. Breeds on Russian and Canadian Arctic tundra; lemming-dependent on breeding grounds. Heavily built; pirates food from other seabirds at sea and scavenges at whale carcasses. Pelagic in winter.
