I saw this Eurasian Wigeon in Lighthouse Pond at Cape May State Park, NJ. The Eurasian Wigeon is the bird in the left center of the picture, with the brownish head. There were about a hundred of the more common American Wigeons on the lake, and supposedly five or six Eurasian ones.

This immature male was in the same place on November 20th, 2010. The head was not fully colored yet, but the gray body, initial head coloring, and buffy forehead stripe indicate that this is a Eurasian Wigeon.
