The American black duck [Anas rubripes] is a large dabbling duck. American black ducks are similar to mallards in size, and resemble the female mallard in coloration, although the black duck’s plumage is darker. It is native to eastern North America and has shown reduction in numbers and increasing hybridization with the more common mallard as that species has spread with man-made habitat changes.

The American black duck somewhat resembles the female mallard in coloration, although the black duck’s plumage is darker. The male and female black duck are generally similar in appearance, but the male’s bill is yellow while the female’s is a dull green. The head is slightly lighter brown than the dark brown body, and the speculum are iridescent violet-blue with predominantly black margins. The black duck has orange legs and dark eyes. In flight, the white underwings can be seen in contrast to the dark brown body. The behavior and voice are the same as for the mallard drake.
