The Mallard (Anas platyrhynchos), also known as the wild duck, is a dabbling duck which breeds throughout the temperate and sub-tropical areas of North America, Europe, Asia, and Australia. Probably the best-known of all ducks, it gave rise to most domestic ducks, apart from the Muscovy Duck.
It is strongly migratory in the northern parts of its breeding range, and winters farther south; it is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies. It also frequents Central America and the Caribbean, and has been introduced into Australia and New Zealand. It is now the most common duck in New Zealand.
In captivity, Mallards come in wild-type plumages, white, and other colours. Most of these colour variants are rare but increasing in domestic collections.
