I bought a male cockatiel around 1 month ago, the shop told me he was around 1 year old. He eats millet from my hand and he steps up if i'm holding a perch and millet. He left the Cage for the first time a couple days ago and started flying and crashing into walls and then falling on the floor...

3 days ago I got a beautiful, very tame 3 month old cockatiel. Aside from putting her on a playstand, what can I do with her to keep her entertained out of the cage?
