I don't know about that, but I do know they're here in TN right now. I "may" belong to a couple of birdwatching listservs - purely for informational purposes, I'd never use the info about ducks during the winter to find some shooting action! Anyway, I know there are a few of them around Clarksville right now, at the refuge. A similar group in KY has recorded observations around Shelbyville- that was last year. It seems that the birds are making their way further north every year.
