Linnaeus specified the type locality as "within the Tropic of Cancer of Europe, America and Asia" but this is now restricted to the Swedish coastline. The parasitic jaeger is now placed with the six other skuas in the genus Stercorarius that was introduced in 1760 by the French zoologist Mathurin Jacques Brisson. The species is considered to be monotypic: no subspecies are recognised. The genus name Stercorarius is Latin and means "of dung"; the food disgorged by other birds when pursued by skuas was once thought to be excrement. The specific... Wikipedia →
