The main ancestor of domestic ducks, frequently found in parks.
Male mallards have a glossy bottle-green head separated by a white collar from the purple-tinged brown breast, grey-brown wings, and a pale grey belly. The rear of the male is black, with white-bordered dark tail feathers. The bill of the male is a yellowish-orange tipped with black. Females are streaked brown. Both sexes have a shiny dark blue patch on a portion of the lower wings (speculum feathers).
