An American Pekin duck, a breed of domestic duck derived from the mallard. Mallards have often been ubiquitous in their regions among the ponds, rivers, and streams of human parks, farms, and other human-made waterways – even to the point of visiting water features in human courtyards. [145] Mallards have had a long relationship with humans.
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.
The 2024 survey produced a statewide estimate of 502,058 breeding ducks, a 4% decline from 2023 but 13% above the long-term (1973 to 2023) average. A graph shows estimates of ducks in the annual ...
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.
Domestic ducks are mostly promiscuous, where wild mallards are monogamous. Domestic ducks have lost the mallard's territorial behaviour, and are less aggressive than mallards. [7] [8] Despite these differences, domestic ducks frequently mate with wild mallard, producing fully fertile hybrid offspring. [9]
Backcrossing in particular can negatively impact non-mallard species as oftentimes the hybrids breed with the more vulnerable species, leading to further genetic dilution. In captivity studies with the American black duck it has been discovered that the hybrids follow Haldane's rule with hybrid females often dying before they reach sexual maturity.
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 world’s oldest known wild bird has sparked “special joy” among scientists after she laid an egg – her first in four years – at the age of 74.
