Mandarin Duck

The mandarin duck is a medium-sized East Asian perching duck, 41–49cm long with a 65–75cm wingspan. The sexes differ dramatically. A breeding male has a red bill, large white eye crescent, reddish face, purple breast with upright white bars, ruddy flanks and two orange sail-like feathers. The female is grey-brown, with a fine white eye-ring and rearward stripe, a pale belly, a narrow white flank mark and a pale-tipped bill. (Wikipedia, mandarin duck account)

Native populations occur in eastern and northeastern Asia and migrate to wintering areas in lowland eastern China and southern Japan. The species is closely related to the North American wood duck, together forming the genus Aix. Mandarin ducks favour sheltered freshwater associated with trees, and their shape is more compact than that of many dabbling ducks. Escaped birds have also established introduced populations in western Europe, especially Britain, and smaller groups occur in North America. (Wikipedia, mandarin duck account)
