Also keep in mind Tyson is at the stage where he's going thru sexual maturity so he's going to be more hormonal, moody, and loud than normal. I'm glad he's not injured, the rest will take time and patience.
if he is being aggressive and attacking, I highly recommend keeping him off your shoulder... I've been attacked and bitten in the face (more than once) and can speak from personal experience - you don't want any holes if you don't have to. My macaw went into a full rage and I was too stupid to leave her alone, pushed the issue, and I got a hole in my lip as a reward for that stubborn stupidity in addition to the numerous gouges in my hands and arms
Thankfully, I knew enough to not pull her off my face and waited for her to let go, or it would have been more than just a hole, it would have been a complete tear through my lip and I would have had to go to the hospital and a plastic surgeon. As it stands, I probably should have but..
don't care about scarring lol Don't underestimate Goffins either - I had a client at the pet shop who lost her entire earlobe to an angry Goffin she let get on her shoulder as well as a big scar near her eye. Not trying to scare you or anything with horror stories, just trying to emphasize using caution.
Also dont underestimate the emotional damage a serious bite like that can do - if my macaw were to do that to anyone but me, I would be forced to rehome her. The woman who's Goffin attacked her? Her husband made her get rid of it because it was seen as too dangerous. Again, not trying to scare you, lecture, or anything of the sort, it's just in my experience these are the things people don't take into consideration. I had warned the Goffin owner about letting him on her shoulder and she let him anyways because that was the only way she could hold him and "bond" with him at the time - the reality is he just wanted to sit in a position where he could vent his aggression and assert his control over the situation and when she tried to stop that, she got bit.
Just be careful, be patient, and he'll come around
