Yeah, you can't even shoot ground squirrels or rabbits with a .22 is my understanding.
No dead animals (or gut piles) with lead in them allowed.
Wish I could remember the web site I found that shows all of the trash they've taken out of sick condor stomachs. Those birds will eat screws, nails, bottlecaps, bits of plastic, all kinds of man-made trash.
Some species were not meant to survive.
