Common goldeneye and hooded merganser hybrid at Vadnais Lake

One of the more interesting birds that was swimming around Vadnais Lake appears to be a common goldeneye and hooded merganser hybrid.
This bird was pretty confusing at first.
But I did a bit of research on the web and found that others have seen this mix and there are pictures here and there and all pretty much look the same.

It was swimming around with a group common goldeneye.In a different group of goldeneye I did spot a hooded merganser female. She seemed to be hanging out with the goldeneye.So it seems that the two species do socialize.
