If his wings are not clipped the bird will fly away. If the wings are clipped all the bird can do is hobble/walk away. If the birds wings are not clipped I would not take it outside at all, even if you got it a large outdoor cage, it could fly away before you put it in the large outdoor cage, unless you placed it in a cat carrier or something then transported it outside!? LOL, I am not a bird person.....
