First I must apologize as I have no picture. Only a video which I cannot upload. I was at our local wetlands this other day and came upon a trio of mystery ducks. I have been all over the internet and cannot ID them. All three had white heads and necks. Two had black bodies with black mottling on a white breast. One had a brown body with brown mottling on a white breast. Their beaks were sort of a pink/red combo. And I guess the most unique thing was this sort of "pharaoh" dance they all did together with their necks. In the video I took, they are sitting down, so I can't see their feet. Perhaps they are a mutation, but they were quite unique looking. On a second visit, when hissed at by a goose, they again did the unique neck dance. Any guesses? Thanks.
