(I really don’t think we’re getting rid of our feral. He’s pretty well settled. My sister gave him a cat bed, which at least has convinced him to stop hanging out on hers.)
I’m sure loads and loads of people have broken this law. If you’re not poaching then, again, the government doesn’t particularly care. But you still probably shouldn’t go out of your way to force them to notice or care.
Joking aside, as a matter of international treaty it is unlawful to kill native North American songbirds, or to possess anything of them such as their feathers or their nests or their eggshells. Yes, even if you just found a feather on the ground. The state doesn’t really care if you pick up a random feather and keep it (provided it isn’t an eagle feather, which is a matter of some other treaties) but it’s probably best, if you’ve done so, not to boast about it everywhere.
It’s also like the second sequel to the book Freaky Friday, Summertime Switch. (The first sequel is about an oracular television.)
