Ducks, Geese, Swans (Anatidae)

The brent goose is a small, dark goose - of similar size to a mallard. It has a black head and neck and grey-brown back, with either a pale or dark belly, depending on the race. Adults have a small white neck patch. It flies in loose flocks along the coast, rather than in tight skeins like grey geese. It is an Amber List species because of the important numbers found at just a few sites. (RSPB)
