An East Asian duck breeding in the far east of Russia, in north-eastern China and Hokkaido. A summer visitor to northern parts of breeding range wintering in southern Japan and eastern China. Has been recorded south to the Ryukyu Islands and Taiwan.
Introduced and now well established in Britain with the main breeding areas are in southern England in Surrey, Berkshire and neighbouring counties but sporadic breeding occurs throughout England and around Perth in Scotland. In addition there are small and scattered breeding populations in Ireland. Has bred or breeds regularly in small numbers in various other European countries including France, Belgium and the Netherlands, Denmark and Norway, Austria, Germany and Switzerland but these populations may not yet be self-supporting. This species is also introduced in California and Utah.
As the native Asian birds continue to decline through persecution and habitat loss the British population has become increasingly important and there may now be more birds in Britain than in China.
In its homeland a bird of lakes and rivers in forested regions, marshes and more open waters in winter. In Britain it is found on lakes and streams in parkland farmland with nearby deciduous woodland.
Seeds and nuts, especially acorns, sweet chestnut, beech mast, grain and aquatic plants. They also take some snails, frogs and tadpoles.
