The mallard /ÃËmælÃâÃÂrd/ or /ÃËmælÃâ¢rd/ Anas platyrhynchos is a dabbling duck that breeds throughout the temperate and subtropical Americas, Eurasia, and North Africa and has been introduced to New Zealand, Australia, Peru, Brazil, Uruguay, Argentina, Chile, Colombia, the Falkland Islands, and South Africa. This duck belongs to the subfamily Anatinae of the waterfowl family Anatidae. The male birds drakes have a glossy green head and are grey on their wings and belly, while the females hens or ducks have mainly brown-speckled plumage. Both sexes have an area of white-bordered black or iridescent blue feathers called a speculum on their wings; males especially tend to have blue speculum feathers. The mallard is 50ââ¬â65 cm 20ââ¬â26 in long, of which the body makes up around two-thirds the length. The wingspan is 81ââ¬â98 cm 32ââ¬â39 in and the bill is 4.4 to 6.1 cm 1.7 to 2.4 in long. It is often slightly heavier than most other dabbling ducks, weighing 0.72ââ¬â1.58 kg 1.6ââ¬â3.5 lb. Mallards live in wetlands, eat water plants and small animals, and are social animals preferring to congregate in groups or flocks of varying sizes. This species is the main ancestor of most breeds of domesticated ducks.
