Hey everyone,
I'm going to try to take a stab at delving further into the id of this Aythya duck. I have never seen Common Pochard before, so I'll use this as a learning experience too!
Looking at the Stokes and Nat Geo Field Guides, it would seem that the best way to describe a male Common Pochard would be a cross between a Redhead and Canvasback. The big field mark in my opinion that shows the bird Ron Payne and Ian Worley saw is a Common Pochard is the head. Male pochards have a peaked head that slopes forward, rather than the head of a Canvasback which slopes towards the back. Redheads have rounded heads. Stokes goes further in saying that, to separate from the rare Canvasback x Redhead hybrids, one must look at the bill- a male Pochard has a three toned bill, with a dark gray base, pale gray middle, and black tip. Taking a look at Ron's picture, the three toned bill is evident. In addition, a male Pochard has dark red eyes while a Redhead has yellowish eyes- the picture might be too blurry to see this trait. 
So in conclusion, based on the characteristics listed above, I agree the bird Ron and Ian found is a Common Pochard. Awesome find, and thank you Jeremiah and Allan for getting the word out! I hope the Pochard, as well as the Tufted Duck, stick around for a little while- it would appear that this Pochard might be the first record for the eastern U.S.! (I do see a record for Quebec several years ago).
Cheers and Happy New Year,

Hi Allan,

As a learning exercise for us more novice birders, couldvJeremiah (or you) explain the characteristics and field marks that enable this ID, especially from such a fuzzy image?
