Appearance:

A medium sized, black and white goose. Black breast, white cheeks and forehead. Differs from the much bigger Canada Goose by the black breast. At distance the white head can be difficult to see, and the strong contrast between the black breast and the light belly is the best character to tell it apart from Brent Goose.

Sound:

Voice: Quite vocal. Contact call a short yapping, barking sound like a small dog. Also other lower, grunting sounds when grazing.
