These birds are well adapted for diving. On occasions they have been observed to stay under water for up to half a minute. They search especially for the bulbs of waterlilies. From danger, they also escape preferentially by diving; hence, the namesake white back is hardly visible in life.
Habitat and Distribution
White-backed ducks live in southern Africa, especially between Senegal and Chad in the west and Ethiopia and South Africa in the east. Their habitat consists of lakes, ponds, swamps and marshes where they are well camouflaged against predators.
