White-faced Whistling Duck
Dendrocygna viduata
The white-faced whistling duck has a long grey bill, a long head, and longish legs. It has a black neck and head, and a distinctive white face that gives it its name, though the amount of white color visible has regional variations among the species. For example, the white-faced whistling ducks with more black coloration are commonly found in western Africa where rainfall supersedes the dry season. 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.
