The American wigeon, also known as the baldpate, is a dabbling duck found in North America and the New World counterpart of the Eurasian wigeon. It is 42–59cm long with a 76–91cm wingspan and weighs 512–1,330g. In silhouette it can be told from other dabblers by its round head, short neck and small bill. The breeding male has a mask of green feathers around the eyes, a cream-coloured cap from crown to bill and a white belly (Wikipedia, general species account).
It is noisy and often identified by its distinctive calls. It breeds in all but the extreme north of Canada and Alaska and in the interior West of the United States, from about April to May. The female nests on the ground near water under cover, laying 6–12 creamy-white eggs that she incubates alone for 23–25 days, and the young fly at around 47 days. The source does not describe its status in China (Wikipedia, general species account).
