Appearance:

Dark-bellied, long-billed shearwater with small head and elongated body. Wings long, narrow and pointed, with pale patches/bands underneath framed in dark base colour of body. Flight fast and powerful. In strong winds hand held pointing slightly backwards. The pale underwing is clearly visible in good light, but the whole bird often seems completely dark. Only shearwater in the region with completely dark underparts, except from dark individuals of the much smaller, and short-winged, Balearic Shearwater. The latter also shows deeper belly and less deep chest. At long distance, and/or bad weather, Sooty Shearwater may be confused with Arctic Skua or even young Gannets. Differs from Gannets by size, shorter neck and no white rump patch. Told from Skuas by bursting series of stiff wing-beats with alternating glides.

Sound:

Mostly heard at breeding ground. A peculiar, rhythmic, coarse moaning, with a disyllabic attack, followed by a deeper, cooing "in-breath".

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.
