American Black Duck
Listen to American Black Duck
American Black Ducks are big dabbling ducks. These waterfowl are considered the heaviest species in the genus Anas, weighing an average of 1,640 g (3.62 lbs).
Both males and females share pale brown heads, dark brown bodies, blue-purple patches on the wings and red-orange legs. Males have olive-yellow bills while females have dark bills.
The American Black Duck is endemic to the eastern part of North America. They inhabit salt and brackish marshes, freshwater and coastal wetlands, estuaries, rivers and edges of backwater ponds. Some flocks live near beaver ponds, forested swamps, and bogs in boreal forests and shallow lakes.
American Black Ducks are omnivores with a diverse diet. These waterfowl birds feed by grazing on land and dabbling in shallow water. They primarily eat plant materials such as wetlands grasses, stems, leaves, seeds and root stalks of water plants. They are also known to feed on small fishes, mollusks, snails, amphipods, mussels and insects.
The current population of the American Black Duck is estimated to be around 1 million birds.
