Habitat and Distribution
Though it likes to stay in rivers and streams during the day it prefers large open waters during the night. This duck likes water in the wooded hills of Africa and also like to hide its nests near running water.
It is an omnivore that feeds off of larvae and pupae usually found under rocks, aquatic animals, plant material, seeds, small fish, snails, and crabs.
It breeds throughout the year in different areas. Incubation is about 30 days by the mother and the fledgling period is 86 days and only the mother takes care of the young. Their egg quantity ranges from 4 to 8 eggs. Also the African black duck makes its cup shaped nest of driftwood and matted grass. Though it builds its nest near running water it is always above flood level and on the ground.
