no trapping experience, but I once "killed" a grouse with a slingshot using marbles as ammo, I hit the wing where it joined the body and broke it, dumb luck, my brother and I chased it down where he put a foot on it (to avoid getting pecked). It died on the spot and we had it for dinner.
But my main point is, they were easy to hunt because we were dumping gravel on our dirt road and birds need the gravel for their gizzards. Instead of bait staking out the nearest gravel patch might get you dinner. slings and stones for weapons.
