I love the varying thoughts in this thread.
I have to say that scatter gunning a duck on the water is like shooting a fish in a barrel. Stalking one on the water with a bow and shooting it successfully is a lot harder than many may think. The ethics of shotgunning have nothing at all to do with the ethics of archery. I can't see how you can say, shoot a sitting rabbit, or make a noise to stop a deer and shoot it while standing still and then call shooting a goose on the ground unethical. They are the exact same thing. I don't shoot turkeys off their roost, but I sure do love to shoot them standing still with their heads extended just like the geese I hunt. Again, it is the same exact thing. Who here would shoot at a flying turkey. If not, why not? You would do it on a goose?
I live in a highly populated area. Every year there are pictures of ducks and geese flying around with arrows in them on the Evening News. This presents all archery hunters in a horrible light. Shooting them in the air with a bow leaves plenty of them wounded and that my friends is considered unethical by everyone who sees those wounded animals on TV. It also fuels the Anti's war chest and troop count. I shoot them in the air and on the ground / water. Nothing unethical or unsporting about it in my book. Stalking them is tough. Using the turkey guillotine broad heads and aiming right below the head pretty much ensures an immediate kill and no bird flying around with an arrow thru it. Hunting ethics requires me to make the most humane kill I can. I owe it to every animal I aim at to optimize the percentage of instant kills I can make. That to me far supercedes a shotgunners ethics that bleed over in some cases to traditional archery practice. I have a lot better chance of that on a goose on the ground.
I love the challenge of aerial shooting. I enjoy watching the arrow flying to meet the goose, I even enjoy watching it miss and sail off into oblivion from where I will try and retrieve it.
