Hi Ryan & other birders,
   Thank you for your kind respone.
However, if you look at Kauffman's book or even better, "The Audubon
Field Guide to NA Birds, Eastern Region," plates 121 and 122 [there
on the same page] you will clearly see the bill differences I mentioned.
My guess is that the little guy is a Tufted duck X Ring-neck hybrid.
   Best wishes,
Lance
