The mallard has hybridised with more than 40 species in the wild, and an additional 20 species in captivity, [13] though fertile hybrids typically have two Anas parents. [14] Mallards and their domestic conspecifics are fully interfertile; many wild mallard populations in North America contain significant amounts of domestic mallard DNA. [15] [16]
Mallards, both domestic and wild in particular are notorious hybridizers, know to frequently hybridize within the mallard complex and even outside of Anas. The willingness to hybridize has concerned conservationists as the gene flow from the mallard may pollute pure populations of more vulnerable species such as the Mexican duck. [2]
A male mallard. The speculum feathers are bright blue with white edges. The speculum is a patch, often distinctly coloured, on the secondary wing feathers, or remiges, of some birds. Examples of the colour(s) of the speculum in a number of ducks are: Common teal and green-winged teal: Iridescent green edged with buff. [1]
By 2010, about 92% of eastern mallards sampled had a significant component of game-farm mallard genes while only 40% of those sampled along northern parts of the Mississippi flyway (a migration ...
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 platyrhyncos, while a small minority are descendants of the Muscovy duck, Cairina moschata.
Mallard landing in approach. In most modern classifications, the so-called 'true ducks' belong to the subfamily Anatinae, which is further split into a varying number of tribes. [10] The largest of these, the Anatini, contains the 'dabbling' or 'river' ducks – named for their method of feeding primarily at the surface of fresh water. [11]
A large congregation of individuals of one or more species of bird that nest or roost in proximity at a particular location. Many kinds of birds are known to congregate in groups of varying size; a congregation of nesting birds is called a breeding colony. A group of birds congregating for rest is called a communal roost.
