(Redirected from Long-tailed Skua)
Alternative name: Long-tailed Skua
50-55cm (including tail projection of 12-20cm)
Two subspecies are recognized, longicaudus from the European and western Siberian area and pallescens from northern Americas and eastern Asia (white-headed juveniles are more common in this subspecies).
Nests on Arctic tundra. Spends winters over open ocean mainly near upwelling zones at the edge of the continental shelfs, usually staying offshore, and very rarely found inland. However, in migration, and especially in central and northern Europe, a juvenile skua found inland on a barren field should be considered a Long-tailed Jaeger/Skua until proven otherwise.
Breeding is reliant upon the availability of lemmings, its principal summer food, in almost the entire breeding range.
