Long-legged Buzzard (Buteo rufinus)
Long-tailed Jaeger (Stercorarius longicaudus)
A large buzzard with variable plumage. Typical traits are: White, almost translucent base of primaries in contrast to black tips, defined black trailing edge to flight-feathers, almost unbarred rufous tail, pale head, dark "trousers", dark carpal patches and rufous under wing-coverts. Due to long wings, the flight profile is most similar to Rough-legged Buzzard, and a combination of structural and plumage characters should be used to tell it apart from Common Buzzard. The subspecies cirtensis (N. Africa, Sinai) has less marked carpal patches and is smaller than the nominate. Immature birds shows more barring on tail and less marked trailing edge to wing. Soars with wings raised to a V, as opposed to the very similar dark morph of Common Buzzard B.b.vulpinus. Flight action heavier and more eagle-like than Buzzard. Often perches on ground.
Sound:Similar to Rough-legged Buzzard, but softer toned.

CCBreeding plumaged adults with streamers unmistakable (streamers comprising two thirds of total tail length). Adult plumage shows less variation than in other skuas. No hint of breast band, and transition between pale belly and darker vent very diffuse. No white patches at base of primaries of underwing in adults. Juveniles easily confused with juvenile Arctic Skua, but are more slender. Wings narrower and primaries and tail longer. Juvenile Arctic Skua shows white patches at base of primaries on both sides of wings, juvenile Long-tailed only on underwing, and on first few primaries of upper. Barred rump and tail coverts in juveniles. Flight elegant and buoyant.
Sound:Calls sharp and less full-bodied than Arctic Skua, and not so mewing. Short, double-accented "kew-wev" or short "kerk" in agitation. Also a long drawn-out "keeeeaah", resembling both Arctic Skua and Common Gull.
