You are probably correct that because these birds were part of a DU banquet, that they would be legit. But they may not be. If they came with no paperwork, then I'd be suspicious to say the least. JJ is correct on the fact that harvested waterfowl cannot be bought, sold, traded, or bartered, but legally pen-raised birds with the proper documentation can be sold. As long as the documentation is still with the mount, they can be sold as many times as you'd like. However, if you didn't receive the proper paperwork at the time of the auction, then it would be very difficult to get the correct paperwork today. I wouldn't hassle with it. If you don't want them anymore, then gift them to a school, I'd suspect they'd appreciate it greatly. I was at a banquet about five years ago where event holder was offering a Hooded Merganser mount as a auction item, and I know for a fact that it was a shot bird. It just so happened to be a bird that a taxidermist was intending to mount for a customer, only to get stiffed on the mount. He felt it was O.K. to give the bird away, which it was, until there was just one single cent bid on it. That's when it became illegal. The guy (taxidermist) who gifted the bird to the banquet had nothing to worry about, because he had gifted the mount to the banquet holder, and they were the one's who were asking for silent bids on it. So, because it was at a DU banquet, that doesn't necessarily mean that it was all good. This topic also comes up when an estate auction comes up to the auction block. Technically speaking, if the estate had mounted waterfowl as part of the estate, then in all actuality, the auctioneer should start the opening bids and ending bids at absolute zero. It just matters who's there to whitness the "goings on"! I hope this clarifies the situation a bit.
