/I have two cockatoos, an Umbrella named Fred and a bare eye named Bandit. Fred is attached to me, and me only, and that is the problem. My mother came to live with me a few years back and she just loves him, always buying him new toys and giving him treats. But he doesn't feel the same way with her, and has bitten her a few times. His bites are not aggressive but as you know even an Umbrella's 'gentle bite' can really hurt.She is good nature about it, and always defends him. He also bit my sister and my niece when they came to visit this Fall. Once again, he did not tear the skin, only slightly bruised it. I want him to accept people better. I have had him for about a year and his last two owners were very good to him. Do you have any ideas of how I can make him more sociable? He also can't stand Bandit. Thank you.
