Hooded Merganser's winter over in our area but are considered uncommon.
There were actually three of them out there in the pond but the third one was some distance from these two. They were pretty skittish and I only got two shots from almost 100 yards away before they flew off. In the first shot the male was shaking his head, obscuring the signature hammerhead crest and in this shot you can see that the female is just beginning to launch herself, to be quickly followed by the other two.
All I was left with was a wake on the water where they paddled themselves into the air and a unique memory. (Unless they come back!)
