Long-tailed Skua, Stercorarius longicaudus, Kongsfjord, Svalbard
The Long-tailed Skua, Stercorarius longicaudus (known as the Long-tailed Jaeger in North America) is a seabird in the skua family Stercorariidae.
This is the smallest of the skua family, distinguishable by its long tail feathers.
It breeds in the high Arctic of Eurasia and North America, with major populations in Russia, Alaska and Canada and smaller populations around the restof the Arctic. It is a migrant, wintering in the south Atlantic and Pacific.
They nest on dry tundra or higher fells laying two spotted olive-brown eggs. Outside of the breeding season they spend most of their time over open ocean and have a harsh kreeah cry. This bird feeds on fish (mainly caught from other seabirds), small birds, scraps, small mammals and carrion. In good lemming years it breeds in regoins, such as the Norwegian mountains, where it is absent in other years. On migration, Long-tailed Jaegers are more likely to catch their own food, and less likely to steal from gulls and terns than larger species.
