Appearance:

Slightly smaller and less heavy than Willow Ptarmigan. Overall greyer plumage, and a more delicate bill. Male summer with grey upperparts and white underparts. Female summer with browner upperparts than male. Both sexes completely white in winter plumage, except for black lores in males. Wings white and tail feathers black in all plumages in both sexes.

Sound:

Call of male a very distinct "rrrrrrr", being a rattling rapid pulse of clicks, like running a stick along a picket fence. Female has similar sounds, but is higher pitched and not so coarse as male.

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".
