The White-faced Whistling Duck breeds in sub-Saharan Africa and much of South America. It does not migrate across the Atlantic Ocean so perhaps a small group of birds colonized one continent from the other. This species is gregarious, and at favored sites the flocks of a thousand or more birds arriving at dawn are an impressive sight. They are often found in association with the Fulvous Whistling duck.
Although the White-faced Whistling Duck has the long neck and legs of other tree ducks, it does not spend much time perched in trees but prefers sand banks. It behaves more like a goose or swan than a typical duck. As the name implies, these are noisy birds with a clear three-note whistling call.
