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.
