The adult female has a brown head and body and a narrower grey bill-band. The triangular head shape is distinctive.

DistributionIn the British Isles, birds breed in eastern England and lowland Scotland, in small numbers in Northern Ireland with numbers increasing gradually, and sporadically in the Republic of Ireland. Large numbers overwinter in Great Britain, after the birds retreat from Russia and Scandinavia.
BehaviorThese are gregarious birds, forming large flocks in winter, often mixed with other diving ducks such as Tufted Duck, with which they are known to hybridise.
FoodThese birds feed mainly by diving or dabbling. They eat aquatic plants with some molluscs, aquatic insects and small fish. They often feed at night, and will up-end for food as well as the more characteristic diving.
