Echo the Cussing Bird!

Echo the African Grey has a dirty mouth! When she gets upset or knows she has done bad she can let the words roll! When I am rubbing her head she bites me and then starts to cuss! The person I got her from said she was in pet store, so I guess she got cussed at if she bite someone! I hate to say this, but I am not going to keep her because of her bad language. She is really a smart bird and knows alot of other GOOD words too!
