won't let me touch his head

[katrinks]

I've got several friends who have had budgies, and all of them have liked to have their heads rubbed. The other 2 budgie that i had before didn't mind either. I know that he's now probably too old to get over whatever his probelm is (he's 4 or 5) but he's never let me touch his head. It's almost as if he's scared of my hands, except he'll sit on my finger, and walk all over them, on my shoulders, etc. he just won't let me touch his head. I just don't understand why.

dont reach over his head to pet it . try reaching up under and start rubbing his chin to get him use to your hand.
