Relatively large wader with long orange or greenish (juveniles) legs. Scaly back and medium long, slightly curved and heavy bill.

Conspicuous white oval patches at upper base of tail. Notable difference in size between sexes (male largest). Often seen feeding in meadows and fields when away from breeding ground.

Appearance:

Small eagle with evenly broad wings and relatively short tail. Easily confused with Greater Spotted Eagle (C. clanga). Flight-feathers darker than the pale brown coverts, both on upper- and underwing. Head and body distinctly paler than flight feathers. Conspicuous pale patch at base of inner primaries on upperwing (diffuse only in C. clanga). Double "commas" on underwing, formed by pale base of primaries and primary-coverts (one "comma" in C. clanga). Wings more narrow than C. clanga, which makes the tail look slightly longer. U-shaped white patch at base of tail. Immature birds with white tipped greater and median coverts, forming two narrow wing-bands. Wings "fingered", but 7th finger shorter than in C. clanga (but varies with age). Sours and glides with wings held horizontally, but with characteristic drooping hand (similar to C. clanga).

Sound:

Vocal at breeding ground, and when courting. Short, barking, high-pitched whistles, not unlike a small dog. Slightly higher pitched than C. clanga and with a purer tone, but very similar.
