YouTube should have some view on training birds and you may be able to use them in your sessions

with any bird you have to get to know them and their body language a little. If he is already hand tamed he might already know how to step up. If not gently press your finger against his belly just above his feet when he steps up reward him. Set up a training routine and practice until he willingly steps up ( you don't have to push against him). As for getting him to stay on you it should come naturally as he gets used to being on and around you. for security , when he is perched on your finger VERY GENTLY hold his toes if his body language tells you that he is uncomfortable let go or break your bond. If he wants to stay on you he will. Good luck
