Distinguishing features
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 speculums 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 behaviour and voice are the same as for the mallard drake. (Wikipedia)
