Their linguistic prowess is limited but hilarious.

My bird knows probably a dozen or more human vocalizations and their rough usage. He has maracas that he likes to fiddle with and sometimes he will tap it against his head, which makes it rattle, and he will say "stahp eht"(stop it). He has a hatred of things that rattle or jingle and he loves to destroy things to make them stop. He is trying to tell the maracas to stop making noise that he causes. He will approach a toy that rattles and will say "stahp eht", and then pick it up or knock it about as if telling it to not make noise will make it not make noise; entirely absent is the concept that he is causing it to make noise.

It is quite funny to be told by a 63g bird to "shaddap" when the TV is too loud for him to sleep in his covered cage at night.

I do wish he would use "bed tyme" more appropriately for when he wants to be put to bed and not just whenever he wants to take one of his 6-10 naps a day. Close enough for an Amazonian Hitler pigeon with a final solution to the rattle and jingle question, I guess.
