Appearance:

A small, dark goose. Thin white collar on adults, juveniles with all black neck. Seems all black from a distance, except for the white vent. Easily told from Barnacle Goose by the lack of contrast between neck and belly, even at long distance. Subspecies hrota, bernicla and nigricans can be distinguished by plumage characters. B.b.hrota: Brownish rather than dark grey belly, and pale between legs. B.b.bernicla: Grey part of belly also reaching behind and between legs. B.b.nigricans: Almost black belly. "Necklace" more distinct, reaching to the front of neck.

Sound:

A bubbling, trembling, ascending, three syllable "ahrahrrhit", quite different from other geese.

Appearance:

Large and heavy skua with broad wings and short tail. The white patches at base of primaries are more striking than in the other skuas, and are visible both on upper and underside of wings. Size comparable to Herring Gull, but build more compact. Seemingly black at a distance, but white wing-patches usually visible. Confusion with juvenile Pomarine Skua possible, but body is heavier (not just the chest), wings rounder, bill longer, neck thicker and tail shorter.

Sound:

Heard mostly at breeding ground. Short, and dry "kek", when agitated. Also a nasal, slightly mewing "kew".
