The Lesser White-fronted Goose (Anser erythropus) is a small goose closely related to the Greater White-fronted Goose (A. albifrons). It breeds in Siberia, with a declining remnant population in Scandinavia. There are different features to identify it, with among them: a dark grey-brown plumage, a small and short pink bill, wings outstriping tail’s edge when they are closed, a white front rising up to the crown (only in adults) and a yellow eye-ring…Three birds were found in France in January 2009: two in Langueux (Côtes-d’Armor) in Brittany and one near Portejoie (Eure) in Normandy.
Pavel Simeonov (Branta-Tours) sent us a very interesting picture showing side by side a Lesser White-fronted Goose and a Greater White-fronted Goose, allowing us to compare both species in flight.
