"Shoulder-perching" dominance and aggression- help! O.o

[Azure Hanyo]

My black-headed caique Galileo is turning into a very likeable little guy, but our beginnings were rough- if you haven't read my intro, he was 8 years old when I adopted him and very aggressive and bitey from being cage-bound most of his life. I have managed to bond pretty well with him, and he will let me scratch his neck feathers and has even started to show excitement when I enter the room by smoke-alarm calling me and coming to the front of the cage for me to get him. Overall, like I said, things are going very well.

I would love for him to perch on my shoulder. But he also loves to try to assert dominance over me, and whenever he is higher than eye-level with me he will bite. Not beaking- a full on, bloody bite. He hasn't done this in almost a week (I think) in our daily bonding time together, but I am going to wait at least until he shows no other aggressive/trying-to-be-dominant behavior towards me before attempting to let him perch on my shoulder again. Does anyone have any ideas or am I on the right track here?

FYI- When he bites me I will tell him "No biting" and push my hand slightly into him and he lets go (no easy feat mind you, his bites REALLY hurt!). He used to glare at me (I swear he glares) when I did this, but the last time he bit me a few days ago he let go as soon as he did it and then pretended like nothing happened. Haha.

You're not going to like this, but I would say dont do it.
You will probably be able to teach him not to bite, but there is one big problem with sitting on your shoulder. You wont be able to see him. You cant predict what he will do, if he is going to bite or whatever while sitting on your shoulder. You will put yourself in a very vulnarable position.
And what will you do when he bites your ear?

Back to the biting issue. Since it is apparent that he loves your company and will do a lot to get your attention this might be a good method for you. A parrot training specialist told me about this and he uses this for all his parrots.
Take a box big enough for him to stand and walk around in, but not for flying. Dont punt any toys or food in there, this will be his tme-out box. So the idea is that he wont like being in there. A plastic see through one is preferable, so he can see what he is missing out on.
Each time the parrot does something you dont want him to do, say NO and place him in the box for 5 minutes. According to the specialist this will work within 5 to 10 time-outs.

Yes...that thought crossed my mind as well. I was afraid someone would assert my doubt that he would ever be a shoulder-percher. Sigh. Oh well.
