Erika and I found this FOS Gadwall at Nisqually National Wildlife Refuge on 4 November 2019. FOS stands for First of Season. Had it been new for the year, it would be FOY. Gadwall are common ducks across northern and western North America. They winter in more southern climes as far as Central America. I find these photos odd. Although they appear well within permissible variation for male Gadwalls, the photographs are actually of the same individual. I assume the differences are due to the bird’s orientation to the light, and not to different plumages on the duck's left and right sides.
