Just hac him step to your arm form a perch, while you hold a treat. Reward him with te treat, and put him back. Gradually step farher and farther from the perch, so the step becasue a longggg step (which he will use his beak to help him across), then eventually it will become a jump, then a flutter then a fly. It took Erin a week of anticipation of fluttering and pacing her stand before she made the 5 ft fly form her stand to my bed to see me. IT takes courage to do that, so it will take time. She used to try to fly to me from the stand and would chicken out and fall 3 inches and grasp on to her toy and climb back off. That was hilarious to watch.
