Game Birds of the World

This distinctively patterned is readily recognized by its white "mask" that extends back to encompass the eyes. It is also uniquely marked with fine black-and-white barring on the flanks, and its underparts are black, which differs from the usual dark-above, light-below combination of colors that provide optimum camouflage. This species ranges from the tropical forests of equatorial South America and Africa to the temperate marshes and shallow lakes of southern Africa and Argentina. It occupies habitats ranging from fresh to brackish waters and from wilderness areas to sewage lagoons or farm ponds. Generally, open-country and freshwater habitats seem to be favored. It feeds by wading as well as swimming and diving, and consumes a variety of plant and invertebrate life.

Although pair bonds are strong in all whistling ducks, the white-faced is unique in that paired birds spend much time in mutual preening. Breeding in both Africa and tropical South America is timed to coincide with the rainy season. Nests are built on dry land or in shoreline reed beds, and 8–12 eggs are usually laid. Observations of wild birds indicate that incubation (by both parents) requires 30–31 days. Like giant bumblebees, the extremely attractive ducklings are a strongly patterned yellow and black. They require about 60–70 days to fledge. Predators, such as foxes, lizards, and caracara, often take the eggs, and storks and caimans capture a considerable number of young.
