While I won't go out of my way to hunt down an offending creature such as a poisonous snake and won't shoot a bird of prey out of the air if it is simply flying around looking for a meal. If that snake is in or around any structure or where my wife might step on it, it will become dog food. The same with ANY large bird if is swoops on my chickens or other small animals. Now Skunk, fox, weasels, bob cats, raccoons, coyotes and those kind of critters are another matter and here lately I have had to root out a few porcupines from a couple of my sheds. Porcupines are not aggressive. but if you reach behind a cabinet and find 1 it is going to hurt trying to get all of the quills out plus they can bite and cases of them carrying rabies have been reported in the area. My little pocket 9 mm and my little Rossi .410 get a lot of use every year. Not so much any of my rifles or larger shotguns or revolvers. Well my 270 gets some as I can reach out several hundred yards to take out a coyote.
