Appearance:

Largest falcon. Heavily built. Grey upperparts and white, speckled underparts. Juveniles with browner plumage than adults, blue-grey legs and longitudinal streaking below. Diffuse moustache-stripe, and the whole head seems dark at distance, lacking a defined cap. Rounder and broader wings, longer tail and bulky belly distinguishes it from Peregrine. Underside of wings with dark coverts in contrast to pale base of flight-feathers. Extremely powerful, but slower flight action than Peregrine.

Sound:

A coarse, drawn out, Peregrine-like "kaaawt", with emphasis on ending, is repeated in series. Much slower paced than in small falcons, and deeper and with different attack than in Peregrine. Also shorter, coarse warning-calls.

Appearance:

Buzzard-sized eagle with long tail, slender build and white patches at base of wings. Occurs in pale and dark morph. Pale birds may be confused with much larger Egyptian Vulture, but note short. wedge-shaped tail of latter. Dark birds harder to identify, but differ from Marsh Harrier by flat, not raised wings, from Black Kite by round, not forked, tail and less arched wings. Buzzards have 5 (not 6) "fingers", shorter tail and more plump build. For separation from Bonelli's Eagle see that species.

Sound:

Very vocal in breeding season. Most often heard is a quite soft, wader-like series of "kli-kli-kli-kli-kli-kli".
