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:

Clearly smaller than Wood Pigeon, and lacks white wing-patches. Most susceptible to confusion with Feral Pigeon. Differs from latter in incomplete dark wing-bars, covering only inner secondary coverts. Colour of back same grey tone as neck and head. Never with white patch at lower back. Underside of wings grey, with clearly defined dark frame. Black trailing edge of tail fairly broad.

Sound:

Song a two-syllable, cooing. Much louder and more accentuated first syllable than in Feral Pigeon. First a short ascending "oooh", immediately followed by a short descending "oohh". Tone quite pure, mostly lacking the rolling quality of Feral Pigeon.
