We had a Goffin Cockatoo. He was a riot. It's like having a small child in the house. He was a rescue and had been ignored, so he would pull his feathers out. We paid a lot of attention to him and he got better about it. He would sit on top of the roof and throw rocks at us if he was feeling ignored. We had a large dog and the dog knew who was boss. The cats just left the room if he was out. My DH taught him to play toss with wads of paper. He would mumble things to himself, but didn't really talk much. He would call my daughter in DH's voice. When we both started teaching he went to live with a retired teacher, because she could be with him more. She rubs him with herbs to keep him from pulling his feathers.
