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:

Unmistakable in breeding plumage, but otherwise easily confused with other marsh terns. Breeding plumage with black head and belly, but pale underwing and grey rump. When in immature and winter plumage it differs from Common and Arctic tern by smaller size and short, moderately forked tail, and from other marsh terns by slimmer body and wings (compared to White-winged tern), and relatively long, thin bill. Both immature and adult winter show dark front edge of wing, and characteristic dark shoulder patch at wing base. Back is dark in immature birds. Grey rump in all plumages. Flight usually different from Sterna-terns, with erratic dives for no apparent reason, and "aimless" change of direction. Note that when foraging over saltwater, flight becomes more Sterna-like.

Sound:

Moderately vocal. Flight call a more or less clear "kleck, or a disyllabic "klee-ake" with accented first syllable. Sometimes slightly rolling "klirr-eke", but never as much as in White-winged Tern. Also a slightly harsher "kreek", but not as raspy as in Whiskered Tern.
