That Goldeneye X Bufflehead photo that Robert Mangile refers us to is pretty
interesting. I note that the male Hooded Merganser, like the drake
Goldeneye, also has a yellow eye, which creates real problems for my
hypothesis of Goldeneye X Hooded Merg. But where does the Mystery Duck get
the cinnamon near his rear end? And could the eye be yellow, but not visible
as such? (I note the yellow eye of a female goldeneye is visible in one of
the pix, but the Mystery Duck is swimming more to the side and somewhat away
from the light in both pix.

It quote Alice in Wonderland, "It gets curiouser and curiouser."
