Wa hunter, many, many years ago when I first started Taxidermy, I had a fully plumed out Canvasback Drake that I thought I would mount to get experience. Worst mistake I ever made. You can probably imagine how it turned out, and I wasted a great bird. A Goldeneye Drake is an awesome bird and you probably don't want to try and mount it as your first bird. I would recommend that you wrap it really good in plastic and store it until you get a little experience. If your really interested in Taxidermy, get a couple of video's and then as Bone mentioned, try and get a couple of Grouse or pheasants and practice on them. Hope that helps and remember, have fun with it. John
