before people arrived there werent any predators, now we have wild dogs, cats, weasels, ferrets, stoats, rats ( that get the size of cats ), hawks
nothing like a yote or a bear though.
but my "turkeys are exceptionally dumb" statement comes from numerous times shooting mobs of them.. blasted one with the shotgun, had a laugh with my buddies, sat back down in the bushes and wait for them to come back, and within 3 -5 minutes the mob was back in the same spot.. drop another couple.. rinse and repeat
maybe ours are a lil more complacent than yours haha
