Although I don't hunt any birds here as I explained in another post, I converse with turkey hunters regularly. Their game it seems is to call in the bird to their gun. They indicate that to seek out the bird by pursuit is a child's game and often joke about now and then calling in some rube to their blind.
I won't get abrasive about it but I expect my state is just a bit tardy in changing their rules to catch up. just as they were with the rifle season for big game. Across the border, in PA they have used rifles to bag turkeys for many years (mostly .22 mag), perhaps never quit since frontier days and there is no unusual shooting accident record there.
I am a state approved & trained hunter/safety instructor, and I am of the firm opinion that very, very few "hunting accidents" are truly accidents in the pure sense of the word. Almost every accident is because somebody did something STUPID ! So often, we hear stories on the news in which the wrongdoer makes the following statement.. " Ithought i was shooting a deer" or "I thought I was shooting a turkey".. A person like that has to be 2 persons, since 1 person alone can't be that stupid !
If one is hunting turkeys he must decide A) Is it a turkey? B) Is it a tom turkey ? C) Is it a clean shot with a clear backstop ? The same goes for a deer, bear or any other game..no excuse for shooting another man in these cases. The charge should be stiff ! A slob hunter is a slob hunter and ruins things for all of us, and it reaches over to 2nd amendment issues (providing grist for the anti-gun mills).
I do disagree with a couple of your conclusions;
1) Predator hunting is not a "second choice" to to big game. I prefer it over big game and I am FAR from alone. I also prefer varmint hunting over big game hunting.
2) Although coon hunting is generally done with dogs and I have done plenty that way..day/night predator calling for coon is coming on strong..it's a real blast !
A narrow , but often used definition; Varmints=woodchucks, rockchucks, prairie dogs, Predators= coyotes, wolves, coon, fox, bobcats
In any case, it is the slob huntere who is the REAL danger and all true sportsmen should do their best to weed him out..
