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:

A very large, long and slender bird. Bigger than Grey Heron. Plumage grey, with contrasting black throat and flight-feathers. White sides of neck. Tertials forms fluffed, ostrich-like rear end. Red crown visible at close range. Easily told from herons in flight by the straight neck. Juveniles with rufous head, lacking the marked pattern of adults.

Sound:

Powerful, resonant and bugling "kriiiiioooo" in various forms. Very far reaching. Often heard in duet where the female immediately answers the male call at a slightly deeper pitch. Also very vocal when flocks meet.
