Brent Goose (Branta bernicla)
Brent Geese are a small goose, with a largely dark plumage and a contrasting white rear end. Two forms occur, dark-bellied and pale-bellied. Dark-bellied occur in the South and East coasts in the UK, they have a dark grey belly and flanks. Pale-bellied occur in North East England, but occasional birds will venture further south, they have pale flanks and belly with a noticeable contrast against the black breast.
Dark-bellied Brent Geese breed in Siberia and migrate to the UK in the winter. They can be found on coastal waters, mudflats and coastal grasslands.
Brent Goose is on the Amber List for Birds of Conservation Concern.
