Hundreds of kilometres from any other duck and without a mate, he was known as "the world's loneliest duck", [4] although accompanied by a rooster, a chicken and a weka. [2] Trevor was named after Trevor Mallard, Speaker of the New Zealand House of Representatives. [10]
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.
The mallard (/ ˈ m æ l ɑːr d, ˈ m æ l ər d /) or wild duck (Anas platyrhynchos) is a dabbling duck that breeds throughout the temperate and subtropical Americas, Eurasia, and North Africa. It has been introduced to New Zealand , Australia , Peru , Brazil , Uruguay , Argentina , Chile , Colombia , the Falkland Islands , and South Africa .

They can be distinguished from most ducks on size, shape, and the speculum. Separation from female common teal is problematic. In non-breeding (eclipse) plumage, the drake looks more like the female. It is a common duck of sheltered wetlands, such as taiga bogs, and usually feeds by dabbling for plant food or grazing. It nests on the ground ...
Tawny mining bee (Andrena fulva) nest entrance. Nesting behavior is also present in many invertebrates. The best known example of nesting behavior in insects is that of the domestic honey bee. Most bees build nests. Solitary bees, like honey bees, make nests. However, solitary bees make individual nests for larvae and are not always in colonies ...
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 hybrids often resemble a dark coloured mallard with a white breast. Mallard ducks also hybridise with the Muscovy duck producing pied offspring. Hybrids between the ruddy duck and white-headed duck are undesirable in parts of Europe [24] [25] where the introduced ruddy duck has bred with native white-headed ducks. The increasing number of ...
