Lesser White-fronted Goose
Anser erythropus
The Lesser White-fronted Goose is the smaller cousin of the Greater White-fronted Goose, sharing its white facial blaze and barred belly but adding a distinctive yellow eye-ring. It breeds on wet tundra and at the northern edge of the taiga across the Palearctic and winters in south-eastern Europe and Asia. It is globally threatened and the focus of international conservation, including reintroduction efforts in northern Europe.
