I wish I could keep a umbrella cockatoo, or any of the big species of cockatoo's, But I'm allergic to their dust. I can be around them for short time and they don't bother me to bad but long term I start having breathing problems and bad sinus allergies from their feather dust. Umbrella's can be so sweet though, I raised one many years ago and she was the most cuddling and precious bird I ever raised. One of the smartest too, But I raised a B&G Macaw and a Double yellow head amazon that were pretty smart birds too. The Double yellow head was talking before it got it's first feathers, No joke! baby the umbrella cockatoo probably had the most tricks up her sleeve, Big Bird the double yellow head had the largest vocabulary, and Piper the B&G Macaw, well he was the better thief. lol I do miss them all!
