The breeding season varies in parts of the range: February to July in Zambia, January to May in Zimbabwe, September to April in South Africa. The nest is usually on the ground among thick grasses, or in reedbeds, but has also been found in rocks in mountainous country, in holes in termite mounds, and in holes in trees. It is a large structure of reeds, grasses and roots, lined with down. Only the females incubate the eggs. Like many waterfowl the young are led to water soon after hatching.
