This attractive American Wigeon was photographed against strikingly blue water just as the sun was lighting up his beautiful metallic green feathers.
Wikipedia has this to say about American Wigeons:
The American Wigeon, also American Widgeon or Baldpate, (Anas americana) is a species of dabbling duck found in North America. This species is classified with the other wigeons in the dabbling duck genus Anas, which may be split, in which case wigeons could go into their old genus Mareca again. It is the New World counterpart of the Eurasian Wigeon.
