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 .
The black-bellied whistling duck is a common species that is "quite tame, even in the wild". [16] It is highly gregarious, or social, forming large flocks when not breeding, and is largely resident apart from local movements. It usually nests in hollow trees (in South America many times in palm trees).
The white-faced whistling duck (Dendrocygna viduata) is a whistling duck that breeds in sub-Saharan Africa and much of South America. This species is gregarious, and at favoured sites, the flocks of a thousand or more birds arriving at dawn are an impressive sight. As the name implies, these are noisy birds with a clear three-note whistling call.
The male Hawaiian duck has an average length of 48–50 cm (19–19.5 in) and the female has an average length of 40–43 cm (15.5–17 in). [10] On average, the male weighs 604 grams (21.3 ounces) and the female weighs 460 grams (16 ounces). [11] The Hawaiian duck is typically smaller than the mallard by 20 to 30 percent. [12] [13]

A female mallard duck incubates her eggs. Egg incubation is the process by which an egg, of oviparous (egg-laying) animals, develops an embryo within the egg, after the egg's formation and ovipositional release. Egg incubation is done under favorable environmental conditions, possibly by brooding and hatching the egg.
Ducks also tend to make a nest before breeding, and, after hatching, lead their ducklings to water. Mother ducks are very caring and protective of their young, but may abandon some of their ducklings if they are physically stuck in an area they cannot get out of (such as nesting in an enclosed courtyard ) or are not prospering due to genetic ...
Vagrants have been recorded in North America. On lakes it prefers areas around the edges, often under small trees. The smew breeds in May and lays 7–11 cream-colored eggs, incubated by the female for 26–28 days. Ducklings leave the nest soon after hatching and learn to fly within about 10 weeks. [12]
