I currently have one lovely Congo African Grey named Parker. She is a wild caught bird so must be over 30 years old. She was a biter when I got her from a family who moved out of the area and just didn't want her any more. She has since stopped biting, after 1.5 years and is quite a sweetheart now. She lives in a household containing a budgie, two ferrets, three border collies (one a puppy) and a miniature Australian shepherd dog.
