In flight, upperwing dark brown on primaries, while secondaries form bluish iridescent speculum, boarded behind and in front by black and white bars; underwing converts much paler brown with white tips, contrasting with darker flight feathers; white tips to secondaries from whitish trailing edge. Bill pinkish-grey with black nail and black patch on upper mandible, sometimes extending over most the bill, though pinkish at base. Legs and feet yellow-orange with blackish blotching.

This species prefers fast-flowing shallow rivers and streams with rocky substrates, especially in wooded and mountainous environments. It can also be found in open, dry habitats and on lakes, reservoirs, lagoons, estuaries with sandy soils, stagnant or slow-running water and ponds.
Dabbling Ducks are generally hardy, easy to maintain and easy to breed. Shelter may be required by some of the smaller species in winter. They should be provided with cover (including marginal pond cover) and loafing areas as well as water. A pen which is 50% water is suggested. The water may be shallow (i.e. no more than two feet deep is required), and muddy areas for dabbling in are also appreciated. These ducks are generally good in mixed collections, although the smaller and quieter species may be bullied. Territorial disputes between ducks of the same species may be avoided by keeping only one pair of each species in an enclosure, unless the area is very large. For a single pair of ducks a pen are of 50 to 100 square metres, depending on the size of duck, should be provided.
Most species are ground nesters and both close ground cover and ground level nest boxes should be provided. Hand-rearing is generally preferred, as these ducks are generally poor parents in captive conditions, particularly in enclosures shared with other waterfowl. These ducks are prone to hybridization, particularly with closely related species, which should be kept apart from one another.
African black ducks are territorial and aggressive, and can be secretive; a separate enclosure is suggested for a pair of these ducks. Cover and loafing areas should be provided as well as shallow water.
This species is difficult to breed. They use close ground cover or a ground-level nest box for breeding, and lays end of April to June.
- The female African Black Duck usually lays from 4-8 brownish eggs and incubates them for 30 days.
- Bird banding:
- Recommended leg band size for the African Black Duck is 11 mm.The leg band can only be applied on a young duck at around 11-12 days old.
- It doesn't matter what leg that you band, but it is good to have a consistent system. Suggested: Left leg = Female, Right leg = Male
