Well I'd love to own one for my little Rita, but It's down right impossible to get one where I live.
In most pet shops you just can't find bird things, even cages are scarce. And don't get me stared on toys or ropes haha.
But as a consecuence I guess they're able to fly wherever they want as long as it's in the backyard or inside the house, I'd never let them go out with me.
