Hartlaub's duck is a small dark duck that lives in the tropical forests of Africa. It spends almost all its time on forest rivers and streams, where it hides among dense vegetation.
Hartlaub's duck differs from most ducks by living in dense tropical forests rather than on open water bodies. It is important for nature because it disperses plant seeds and serves as prey for forest predators.
Immature form that undergoes metamorphosis before adulthood.
