Appearance:

Very large and heavy bird with heavy bill and rounded tail with straight outer tail-feathers. Both sexes lack wing-bars. Males much bigger than females. Plumage mostly black with brown wings and yellowish bill. Females mottled brown with brick-red breast, throat and chin. Lower back greyish, contrasting with rufous, heavily barred, tail.

Sound:

Display-sounds from male unmistakable. Four phased song: First a slow introductory, double-tapping phase which suddenly bursts into an accelerating crescendo followed by a distinct pop. Then closing with grinding and hissing sounds. Female calls with a deep nasal "kok kok".

Appearance:

Orange legs, black and orange bill. Differs from juvenile White-fronted Goose by less contrast between cheeks and base of bill and crown, more prominent pale edges on back feathers, and by bill colour. Has much darker back than Pink-footed Goose (and never greyish). Colour of legs and bill can be surprisingly difficult to judge in unfavourable light. 2 subspecies that may be considered separate species in near future: A.f.rossicus has shorter bill with more extensive black markings than A.f.fabalis.

Sound:

Do not call as much as other grey geese. Sounds similar to the lower sounds of Pink-footed goose, with various reedy calls, but harder, less nasal and more of a "sore throat".
