My first Birb lol

This is Poboy or Po for short. He will be coming home with me Friday. I've never owned birds but I did work exclusively with them for 2 years at a local family owned pet store. I love love love birds and especially cockatiels. I've also been out of practice for years. I have a vet apt already set up next month for him but I would like to see what your enclosures look like and toys. And ANY help or advise would be graciously accepted.
