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 .
Hundreds of kilometres from any other duck and without a mate, he was known as "the world's loneliest duck", [4] although accompanied by a rooster, a chicken and a weka. [ 2 ] Trevor was named after Trevor Mallard , Speaker of the New Zealand House of Representatives . [ 10 ]
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.
The Mallard duck is possibly the world's most capable bird to hybridise with other duck species, often to the point of the loss of genetic identity of these species. For example, feral mallard populations have significantly reduced wild populations of the Pacific black duck in New Zealand and Australia through cross-breeding. [citation needed]
Most breeds and varieties of domestic duck derive from the mallard, Anas platyrhynchos; a few derive from Cairina moschata, the Muscovy duck, or are mulards, hybrids of these with A. platyrhynchos stock. [2] Domestication has greatly altered their characteristics. Domestic ducks are mostly promiscuous, where wild mallards are monogamous ...
The White Muscovy and the Pekin are the two most common purebred, commercially farmed ducks. Hybrids of the two are hardier and calmer, in addition to exhibiting natural hybrid vigor. [2] The incubation period of the hybrid eggs is between the mallard and Muscovy, with an average of 32 days. About half of the eggs hatch into mulard ducks.
African black duck. The African black duck is a black duck with pronounced white marks on its back, a dark bill, and orange legs and feet. A purpish-blue speculum is often visible, especially in flight. It lives in central and southern Africa. It is also known as the black river duck, or (A. s. leucostigma) West African black duck or Ethiopian ...
The hybrids often resemble a dark coloured mallard with a white breast. Mallard ducks also hybridise with the Muscovy duck producing pied offspring. Hybrids between the ruddy duck and white-headed duck are undesirable in parts of Europe [24] [25] where the introduced ruddy duck has bred with native white-headed ducks. The increasing number of ...
