If it's legal, it's fair game. If it's endangered in any way, I don't want to shoot it. Fortunately, it's illegal to shoot anything endandered so I don't have to worry about what'd endangered and what's not - just what is legal and what's not, and the first question subsumes the second. Probably the only animal species not endangered yet still illegal, which I think need their ranks thinned nevertheless, are
homo sapiens sapiens and
canis lupis.
In other words, all endangered species are illegal (that's good), but not all illegal species are endangered (bad, if they are a nuisance or taste good).
I do need a REASON to shoot anything. But that reason doesn't have to be "to eat it". It can be (a) to eat it, or (b) because it's a nuisance species.
Nuisance species (to ME) can include a wide variety of things, including animals which tear up crop fields (feral hogs), screw up the water drainage (beavers), and animals which kill game which *I* like to hunt (or their eggs). Including coyotes, bobcats, and things that eat turkey eggs and quail eggs (racoons, skunks, armadillos, possums, etc.). Yes, some humans need killin too, but for better or worse (better I suppose, to maintain an orderly society), killing the ones need killing is highly illegal.
But no, nothing is sacred, no matter how intelligent or how cute - if it tastes good or is a nuisance, its in jeopardy.
But I can't quite bring myself (thankfully) to cross the thresshold of using "because I want to stuff it / it would make a good trophy", alone, being legitimate. The culture I come from says that trophy hunting for trophy hunting's sake is wrong.
