Actually,the crow is a rather smart bird. If you want to know what a stupid bird is: 1) Domesticated turkeys are stupid as hell. 2) Chickens are dumb.
-I'll have to retract Number 2 up there. Studies show chickens aren't so dumb after all,they just seem that way. They are actually very intelligent. Number 1 is a 'no-brainer',
because it's true. Opossum are necessary in the enviroment,but they are brutally dense and slow as molasses.
Actually I have kept an opossum as a pet. He was potty trained to go in a litter box, came when he was called, slept in the bed that was designated to him, and could figure out how to get in to....or OUT of ANYTHING. Additionally, although they prefer to "mosey", they are capable of moving quite quickly when they so choose.
