Branta bernicla
Small for a goose (comparable to the size of a mallard), the brent goose is mainly dark with grey, white and brown. They have a black neck and head, with a pale or dark belly - this depends on the race. Adults have a small white patch on their necks.
They are often seen flying spaced out within their flocks along the coast, unlike grey geese who fly in a tight formation.
Their diets mainly consist of vegetation, especially eel-grass.
