"My African Grey likes to squawk like my Quaker Parrot just so the Quaker will get in trouble for making to much noise. The Grey also yells at the cats when they start playing too rough. THis guy knows hundreds of words and, when he wants a treat, he asks for it by name. Give him something else and it gets dumped. When he is outside his cage, he has also learned how to unscrew the bolts holding it together. He has also learned how to open the food dish doors on the outside and make them look like they are shut so he can sneak out when we aren't looking. Several times I've come home from work to find the little guy on top of his cage with the door shut and secure and a slightly propped open food dish door. One day, I happened to catch him proping that dish door open. Very clever animal and definitely more intelligent than several people I know."LOLOL! Sounds like my escape artist! I had to put "snaps" on the dish doors on his cage to keep him from taking himself for a walk. If we are out in the living room and he is out of the cage, he will come walking in to look for us.
I had a stray cat that could open doors by putting paws on both side of the door knob and turning it. It would then claw under the door to open it all the way.
It would attempt to open the front door but couldn't because that had a release latch built into the door handle on the inside. Could always know when he wanted out by seeing him try to open that door.
I chalk it up to a survival instinct.
