The mallard (/ ˈ m æ l ɑːr d, ˈ m æ l ər d /) or wild duck (Anas platyrhynchos) is a dabbling duck that breeds throughout the temperate and subtropical Americas, Eurasia, and North Africa. It has been introduced to New Zealand, Australia, Peru, Brazil, Uruguay, Argentina, Chile, Colombia, the Falkland Islands, and South Africa.
The American black duck (Anas rubripes) is a large dabbling duck in the family Anatidae.It was described by William Brewster in 1902. It is the heaviest species in the genus Anas, weighing 720–1,640 g (1.59–3.62 lb) on average and measuring 54–59 cm (21–23 in) in length with an 88–95 cm (35–37 in) wingspan.
A duckling is a young duck in downy plumage [1] or baby duck, [2] but in the food trade a young domestic duck which has just reached adult size and bulk and its meat is still fully tender, is sometimes labelled as a duckling. A male is called a drake and the female is called a duck, or in ornithology a hen. [3] [4] Male mallard. Wood ducks.

Possible backcross between a Mallard and American black duck All the species within the mallard complex are known to hybridize with other members within overlapping ranges. Mallards, both domestic and wild in particular are notorious hybridizers, know to frequently hybridize within the mallard complex and even outside of Anas.
A few are kept for show, or for their ornamental value. Most varieties of domesticated ducks, apart from the Muscovy duck and hybrids, are descended from the mallard, which was domesticated in China around 2000 BC. Duck farming is simplified by their reliable flocking behaviour, and their ability to forage effectively for themselves. Over 80% ...
They can be distinguished from most ducks on size, shape, and the speculum. Separation from female common teal is problematic. In non-breeding (eclipse) plumage, the drake looks more like the female. It is a common duck of sheltered wetlands, such as taiga bogs, and usually feeds by dabbling for plant food or grazing. It nests on the ground ...
The female is light brown, with plumage much like a female mallard. It can be distinguished from that species by the dark orange-edged bill, smaller size, the white speculum, and white belly. [12] Both sexes go through two moults annually, following a juvenile moult. [10] The gadwall is a quieter duck, except during its courtship display.
