White-faced whistling duck
The white-faced whistling duck (Dendrocygna viduata) is a whistling duck that breeds in sub-Saharan Africa and much of South America. This species is gregarious, and at favoured sites, the flocks of a thousand or more birds arriving at dawn are an impressive sight. As the name implies, these are noisy birds with a clear three-note whistling call.
Unlike most waterfowl, white-faced whistling ducks often perch in branches and are known as tree ducks. When alarmed, these ducks stand straight and freeze. They feed on grass, seeds, and aquatic mollusks. Adult white-faced whistling ducks have a black and white head and a reddish chestnut brown breast. Breeding begins at the start of the rainy season. After breeding, white-faced whistling ducks undergo a flightless molt period that lasts from 18-25 days.
