An effective relationship with your parrot must begin with mutual trust. The baby parrot usually comes with these elements already established in his behavior. Cooperative games between you and the bird such as step-ups and towel-peek-a-boos should be repeatedly stimulated, enacted and reinforced to maintain tameness as the bird matures. You can also prevent the development of stress reactions to toweling by cuddling, snuggling and playing "peek-a-bird" in a towel. Practice in safe, neutral territory and be sure that your hand is approaching from below toward your bird's belly, rather than from the front.
