Mystery Duck?

My first thought was merganser too. But after looking at a few pictures of them I never really found anything that looked similar. Maybe this is a young female, and thats why it didn't look like any of the pictures I found? If it is a hen hooded merganser, the one I shot that we never recovered was probably a male. And from the looks of it, that'd be a hell of a bird to lose. :/
