jstanley, it's common in the sense that a Mallard/Gadwall cross/hybrid is nicknamed "brewers duck" but shooting one in the wild is still a trophy and a once in a lifetime kill. It's like a leusistic mallard or other hybrids, your lucky to get one in a lifetime. I have been hunting all my life and have never seen a brewers duck in the wild before. I have mounted several of them but never had the privilege to shoot one myself. Congrat's in getting him. Was he in a flock of mallards or Gadwalls when you shot him? Also just an idea, I would look in to putting that bad boy under glass so he stays dust/dirt free for ever. Again great kill bud!
