Attacking/Dominance mounting my knee?

Every once in a while Meucci (a male) will climb onto my knee and and aggressively nip and sometimes scratch at it while making a rapid chirp-like squeaking sound. Thinking it might be a dominance behavior I've taken to placing my over his back and gently grabbing at his eats and scruffing him right back and and gently knocking him off. He is little deterred and almost seems encouraged by this. I'll even pick him up and put him in the cage and sometime he'll come right back down to the level I'm sitting at and try again. He'll nip at my fingers too with some force but not enough to be painful.



Eventually I guess he decides that someone has won and goes back to behaving as normal. Is this fighting behavior? Mating? Can I win?



I've had him for just over a month now and I want it to be well known to him that I am in charge here.
