The African Black Duck can be found over most of South Africa with the exception of the very dry regions in the west. They tend to live their lives in the same area and do not travel far.
Most of their food comprises of insects and other invertebrates. They do also eat some plants. It has also been recorded catching and eating small fish.
The female builds a nest near water and she normally lays between 4 and 11 eggs.
African Black Ducks are timid birds and will fly if disturbed. They prefer quieter stretches of rivers where they may often be seen in pairs.
