American Wigeon
The American Wigeon (also American Widgeon or Baldpate), Anas americana is a species of wigeon in the dabbling duck genus Anas. If this is split up, all wigeons will go into their old genus Mareca again. It is a common and widespread duck which breeds in all but the extreme north of Canada and Alaska and also in the Interior West through Idaho, Colorado, the Dakotas, and Minnesota, as well as eastern Washington and Oregon. It is the New World counterpart of the Eurasian Wigeon. The conservation status of this bird is Least Concern.
This dabbling duck is migratory and winters farther south than its breeding range, in the southern half of the United States, Idaho, Washington, Oregon, and the Mid-Atlantic coastal region, and further south into Central America and northwestern South America. It is a rare but regular vagrant to western Europe. It is highly gregarious outside of the breeding season and will form large flocks.
