If the bird is attached to you, then it will not try to fly off. You should get the clue from how the bird act inside your home. It can be tested with let the bird out of the cage but all the windows and doors are closed. If the bird wants to escape, the it would be wondering around in front of the window quite often. If the bird is attached to you, then you will be the center of attention. It requires you to develop a close relationship with the bird first. As I learned from other bird owners, it is easier to get the bird attached to you if you just get one bird instead of two. Sure a single bird might look lonely, but they'd just become attached to each other if there are two of them. You need to have just one bird, and spend a lot of time and attention with it.
