At the veterinarian office that I work at we have 5 birds, one being an African Grey. He has got to be the funniest thing. I am not sure when they got him, but I do know that they rescued him from a drug dealer's house that was on the run and he just abandoned him. Anyways, though he won't talk unless he thinks that you aren't listening ( I think that has to do with the was he was treated by his ex owner). One time when I was on my lunch break I heard him pretending to be Dr. Kitterman. He said "Hello, this is Dr. Kitterman........yes, uh-huh...yes, now about the lab work. (He always trail off at this part) and then he says "Well, thank you and have a nice day...click." I think that had to be one of the best things that I have heard him say so far. He says many other things also, gives kisses, etc. Everyone loves him, and he is just a joy to have. I am not sure about the other type of bird....but they may just as well be very nice.
