I think a lot of the "shooting on the ground" thing has to do with when one took up hunting. Someone who has just taken up hunting, no matter their age, probably won't be a very good wing shot. They'll waste a lot of ammo and never cut a feather. Out of shear desperation, they'll ground swat them. As they get better they ar more likely to improve their shooting and, as they take more birds on the wing, they'll shoot fewer on the ground. I was 30 years old before I hunted from a blind or over decoys-all our shooting was pass shooting. I was brought up that you don't shoot quail on the ground, ducks on the water, does (they were illegal when I was growing up), piglets that are less than half the height of their moms, turkey off the roost, armadillo, and no shooting into a squirrels nest. I grew up in Florida and shot only 2 armadillo (caught and released a lot more), we ate both of them. I still prefer pass shooting waterfowl. I still follow those guidelines, except that now I do shoot does-every chance I get. They're not better or worse than anyone else's hunting rules, just the way I was brought up. Just like using a flyrod, it ain't for everybody. I'd rather catch 1 fish with a flyrod, than 10 with a spinning rig and livebait. Garden fodder or corn for trout isn't wrong, it's just not for me.
