Philippine ducks are close relatives of the mallard duck, with which they readily hybridise in waterfowl collections. As their name suggests they can be found in the Philippines and nearby islands. Unfortunately, their numbers are declining due to hunting and loss of freshwater habitats.
Unlike mallards the sexes have the same plumage but the male is larger than the female.
As well as freshwater habitats they are found in mangrove swamps and even in the sea. They feed on seeds, including rice, plants, insects, shrimps and fish.
