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".
