Greylag Goose Anser anser
Here in Norfolk Greylag Goose is chiefly known as a feral species but wild birds from northern populations do winter here in small numbers. Icelandic birds sometimes crop up among Pink-footed Goose flocks and neck-collared birds from Orkney have also wintered here. Domesticated Greylag Geese, including those in the wild with some domestic ancestry, are dealt with separately here - only birds that do not show any sign of domestic ancestry are dealt with on this page.

Typically Greylag Geese have pink legs but among feral populations at least, orange-legged birds are very common.

Icelandic birds among Pink-footed Geese look much smaller than the local feral birds - barely any bigger than the Pink-footed Geese.

Birds with pink bills occasionally turn up in western Europe and these are sometimes mooted as the eastern race rubirostris. However, there is a broad zone of intergradation and it is likely that these birds come from much less far east than the core range of rubirostris. This bird with a Swedish neck collar is one such example (this bird was seen flying past Porthgwarra on 9th October before arriving on the Hayle estuary the following day):

These pink-billed birds were much further east, but I gather that even in the Arabian peninsular birds over-wintering are not believed to have come from within the range of pure rubirostris:
