oh brother, my cousin has a cockatoo. Her daughter bought it, acquired a boyfriend, and promptly dumped the bird on mom and dad. the bird bonded to my cousin, but it is hysterical and jealous of ANYONE that gets near her, including her kind gentle husband.
This bird shrieks and carries on even when she's on the phone.
They can put its cover on and tell it it's bedtime, but you can't fool that bird.

I am not sure why anyone would want to take this bird out of its natural environment.
