A bird of eastern North America, breeding in Canada to the Arctic Sea and in northern-most eastern USA west to Wisconsin and Minnesota. It winters from the Canadian border south in the US, but does not reach the Gulf of Mexico.
This duck is a rare vagrant to Great Britain.
Two subspecies are recognised by some authorities: A. r. rubripes and A. r. obscura4
The hybrids are difficult to distinguish in the field. Hybrid females appear to die before reaching sexual maturity leading to the belief that they are separate species.1
They breed on lakes, ponds, rivers, freshwater and coastal marshes.
These birds feed by dabbling in shallow water, and grazing on land. They mainly eat plants, but also some mollusks and aquatic insects.
The clutch consists of six to fourteen greenish-buff eggs which usually hatch at about 30 days.
