Appearance:

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.

Appearance:

Large gull with deep chest, light grey back and heavy yellow bill with red spot (adult). Pinkish legs and black tipped primaries with white windows. Winter plumage with streaked head and neck. Develops grey mantle in 2.nd winter. Young birds may be difficult to distinguish from juvenile Greater- or Lesser Black-backed Gulls, and the species shows notable variation in both plumage and size. Juveniles generally shows darker head and less contrasting markings than Greater Black-back, and pale inner primaries (window), as opposed to the all black hand of young Lesser Black-backs.

Sound:

Quite vocal. A long and strong "ay-kay-kay-kay-kay" with fading strength commonly heard. A deep "ga-ga-ga" heard from anxious birds. All calls much deeper pitched than Common Gull. Difficult to distinguish from Lesser Black-backed Gull, but tone is less nasal.
