Lesser White-fronted Goose Anser erythropus

The Lesser White-fronted Goose is a little smaller than the usual European White-fronted Goose, with a pink bill and a thin yellow eye-ring.

It breeds in the far north of Eurasia and winters in southeastern Europe and (mainly) in southern Asia. It is a very rare vagrant to the UK.

The Pink-footed goose seemed besotted with the Lesser White-front, following it everywhere.
