The Mariana mallard was a resident allopatric population – in most respects a good species – apparently initially derived from mallard-Pacific black duck hybrids; [139] it became extinct in the late 20th century. [140] The Laysan duck is an insular relative of the mallard, with a very small and fluctuating population.
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.
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 Mariana mallard or Oustalet's duck (Anas oustaleti) is an extinct species of duck of the genus Anas that was endemic to the Mariana Islands.Its taxonomic status is debated, and it has variously been treated as a full species, a subspecies of the mallard or of the Pacific black duck, or sometimes as a subspecies of the Indian spot-billed duck.
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.
Anatidae: Eurasian teal (Anas crecca), gadwall (Anas strepera), northern pintail (Anas acuta), mallard (Anas platyrhynchos), greater scaup (Aythya marila), long-tailed duck (Clangula hyemalis), northern shoveler (Anas clypeata), garganey (Anas querquedula), Eurasian wigeon (Anas penelope), ferruginous duck (Aythya nyroca), common goldeneye ...
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.
This is a list of the breeds of domestic duck which have official recognition at national or international level. [1]Most breeds of duck derive from the wild mallard, Anas platyrhynchos, while a small minority are descendants of the Muscovy duck, Cairina moschata.
