Once when my wife and I were at the Nashville Zoo we came out of the reptile house to find a parrot in a cage. He said "Hello!' to us. We thought this was cute so we stayed and tried to get him to say it again. Then an older couple came out and the parrot started saying, "Oh shit, ohhhhh shit!" At the time it was funny, and I assumed he'd picked it up at the zoo. I later learned that most of the zoo's parrots are donated or rescued, so, in spite of having a bit of a foul mouth it seemed like his story had a happy ending.
The more I learn about parrots, though, the more I feel that they're just not meant to be kept as pets, possibly not to be kept in captivity at all. I realize many natural habitats have been destroyed, and saving some of these magnificent birds is better than saving none at all, but I can't help feeling sad whenever I see one in captivity, no matter how funny its behavior may seem.
