Appearance:

At a distance quite similar to Guillemot. Bill deep, rectangular and with white markings. Flanks unstreaked and armpits white. Tail longer than in Guillemot, with legs not protruding behind tail in flight. Tail often held clear of the surface when swimming. Cheeks white in winter, with broad, short and black eye stripe. Neck collar short and wide. Upperparts blacker, and underparts whiter than Guillemot. Heavy neck, head and bill, in combination with the long tail, gives it a front heavy, and different profile from Guillemot, whether perched, swimming or flying. Top of head in line with tip of uptilted bill when swimming.

Sound:

Very coarse and deep voice. Grunting or snore-like, with little phrasing. Mostly heard at breeding ground, but also sometimes at sea.

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.
