The mallard itself is the ancestor of most domestic ducks, and its naturally evolved wild gene pool gets genetically polluted in turn by the domestic and feral populations. [ 122 ] Over time, a continuum of hybrids ranging between almost typical examples of either species develop; the speciation process is beginning to reverse itself. [ 123 ]
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.
Duck breast topped with foie gras. Duck is particularly predominant in the Chinese cuisine—a popular dish is Peking duck.Duck meat is commonly eaten with scallions, cucumbers and hoisin sauce wrapped in a small spring pancake made of flour and water or a soft, risen bun known as gua bao.
The Muscovy is commonly reared for meat. [4]: 78 Mulards from the crossing of a Muscovy duck (Cairina moschata) and a wild-type mallard (Anas platyrhynchos)In commercial production, it is often crossed with a mallard-derived domestic duck such as the Rouen or Pekin to produce the hybrid known as a mulard.
The Philippine duck is a dabbling duck and a member of the genus Anas. It has no subspecies and so it is monotypic. [3] It belongs to the Pacific clade of Anas along with the koloa, the Laysan duck, the Pacific black duck, and the extinct Mariana mallard. [4] The scientific name comes from the Latin Anas, 'duck' and the Philippine island Luzon.

Including the Mexican duck in the mallard is a relic from the usual practice of much of the mid-late 20th century, when all North American "mallardines" as well as the Hawaiian and Laysan ducks were included in the mallard proper as subspecies.
This sociable duck is found in a variety of wetland habitats, and its nesting habits are much like those of the mallard, which is encroaching on its range in New Zealand. [10] It feeds by upending, like other Anas ducks. It has a dark body, and a paler head with a dark crown and facial stripes. In flight, it shows a green speculum and pale ...
