I don't think you're doing anything wrong - it sounds just like my bird. I've only had my Budgie for 2 wks - he is older (don't know his age or training - maybe 3yrs?). I think because they're new to us they're rightfully still a little nervous. If they're babies or older they are really checking out your reaction too - so be gentle & calm.
I can often distract Laker from biting just by talking to him. Although he's smart I don't think he can divide his attention too much, so I distract him by chirping or clucking like a Budgie or talking. When he's out I will let him just be himself too (free to do what he likes) & I'll read. He keeps checking on me & even flies to land on top of me.
I think he needs to remind me from time to time that he's up to a fight if I get too pushy. I am not encouraging the biting - which means I stop everything I'm doing if he does it & try not to repeat the actions. I'm also encouraging him to Step-up (using verbal commands & a hand held stick), but often at this point he flies to the cage or elsewhere during training. But I've noticed some improvement & I am hopeful it will continue to get better. He is less likely to leave my hand or the stick now, until I present him with his new spot/perch.
If a budgie bites or runs away you might try working with him some more
while he's in the cage - just hanging out & maybe feeding some millet from the palm of your hand. This way he'll learn to trust you & will not be so bite oriented.
PS willahlborn - great editing job! - I hope
MaskedBird57, that you can smile over this - but the translation was a little easier to read

I also get excited when I type but it is a good idea to proof read so there's less misunderstanding. I still make tons of mistakes - i've seen lots from others too.
