I have a U2 (Umbrella Cockatoo). Boo is a female and she is around five years old now. I've had her out of an egg and handfed her. She doesn't know she's a bird. She thinks she's a Yorkie. Noel, is her best friend. I tell Noee go give Boo kiss and Noel will run to her and lick her all over her beak and face. Boo has her own room and is out of the cage all day long. A lot of times you'll find her up on top of the back of the couch, looking out the window with the Yorkies and barking right along with them. She also take the ball and calls Noeee Noeee and when Noel come running to her she throws the ball to her or if all the Yorkies are waitiing and barking for Boo to throw the ball she'll always manage to make sure that Noel is the one that catches it. The only downside is she is very destructive. They are chewers so she is in her own room most of the time, unless I can supervise her 100 percent. She's already destroyed the keyboard on two laptops
We really love her though. She's a gentle giant and the Yorkies have taken her in as one of them. They play together of course supervised.
