Hybrid of mallard duck × Muscovy duck. Charles Darwin also described duck hybrids in The Variation of Animals and Plants Under Domestication: Hybrids are often raised between the common and musk duck, and I have been assured by three persons, who have kept these crossed birds, that they were not wild; but Mr. Garnett (13/45.
The mulard duck, hybrid of the domestic Pekin duck and domesticated Muscovy ducks. Brewer's duck, hybrid of the mallard and gadwall. Genus Anas. In Australia, New Zealand and other areas where the Pacific black duck occurs, it is hybridised by the much more aggressive introduced mallard.
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.
Usually, the bird hybrid shows intermediate characteristics between the two species. A "successful" hybrid is one demonstrated to produce fertile offspring. According to the most recent estimates, about 16% of all wild bird species have been known to hybridize with one another; this number increases to 22% when captive hybrids are taken into ...
The richness and variety of the wildlife of Ethiopia is dictated by the great diversity of terrain with wide variations in climate, soils, natural vegetation and settlement patterns. Ethiopia contains a vast highland complex of mountains and dissected plateaus divided by the Great Rift Valley , which runs generally southwest to northeast and is ...
The mulard (or moulard) is a hybrid between two different genera of domestic duck: the Domestic Muscovy duck (derived from the Muscovy duck Cairina moschata) and the domestic duck (derived from the mallard Anas platyrhynchos). American Pekins and other domestic ducks are most commonly used to breed mulards due to the breed's high meat production.
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. [ 7 ] : 97 These hatch in about four weeks and grow rapidly like a mallard-type duck, but to about the size and weight of the Muscovy.
