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.
