In Sweden, Finland and Russia they shoot Capercaille and Black Grouse out of the tops of trees with both shotguns and rifles. I guess that's their hunting culture. Who is to judge? Also, a while back, I was watching the MeatEater series with Steven Rinella, he was hunting Blue Grouse up in Alaska, shooting them out of the tops of trees with a .22 rifle. That was pretty interesting, a lot of sweat equity climbing through a steep rain forest to shoot a couple grouse. You certainly couldn't use a dog for flushing when the birds are sitting 200 feet up a tree.
