Thank you to all who reply to my question! I have a 28-year-old orange wing Amazon who is full of energy. I've had him for about a year now and we've bonded well for the most part. He is in love, obsessed ,inseparable with this certain chain toy. I've always wanted to be able to take him outside, but I'm always afraid he'll fly away. He's been outside before in his cage to enjoy fresh air but he's never been outside without one. The only way I really train him is with his chain. He literally goes wherever the thing is that is the only way I can get him to step up or stay on my shoulders.. so my theory is if I take him outside he'll focus on the toy. if he were to fly into a tree I could just shake his chain and he'll fly to me because that's what he does inside .my other option is is a bird harness which I'm pretty sure I would never be able to get on him because he is a biter or clipping his wings but I really do not want to ruin his beautiful feathers.. I just want him to be able to be outside and fly around but come back or take him places to show him off
