The white-faced whistling duck (Dendrocygna viduata) is a whistling duck that breeds in sub-Saharan Africa and much of South America. As the name implies, these are noisy birds with a clear three-note whistling call. This duck has a long grey bill, a long head, and longish legs. It has a black neck and head, and distinctive white face that gives them their name. The back and wings are dark brown to black, and the underparts are black with a fine white barring on the flanks. The neck is chestnut. Males and females have similar plumage. Juveniles are similar in color to adults, but have a much less contrasted head pattern.
