RE: Help me id this duck
They're Oldsquaws. I would DEFINITELY get the drake mounted. It is not everyday you get one. I've been waterfowling 15 years in NC and never shot one. My buddy who guides sea ducks maybe gets 10 a year.
The reason you can't find current info is the American Birding Association petitioned successfully to get the name changed to "Long-tailed Duck" because of PC. It'll be an Oldsquaw with me until the day I go from the earth!!!!
