Appearance:

Large and athletic falcon. Adults slate-grey above. Underparts white with black barring. Head almost black. Juveniles with brown tone to plumage, coarse longitudinal streaking below and paler head. Differs from the smaller falcons by less pointed wings, heavier hips and short tail. Highly contrasting and broad moustache-stripe. Smaller than Gyrfalcon with a more compact silhouette. The wings are not as broad, and belly not as deep. Underside of wings evenly barred, without contrasting coverts. Flight-pattern can recall Fulmar, with shallow, stiff wing-action.

Sound:

A harsh, drawn out "kiaaaa" with emphasised endings repeated in series. Much slower than Merlin, but higher pitched than Gyrfalcon. Also shorter, coarse warning-calls.

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.
