Anser fabalis
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.
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".
