I was not sure what he was doing when he somewhat grabbed and stood on my finger while I had him in my bed. He then did this movement where he all of a sudden was on his back. Now he does it often and even lets me flip him over and then rub his belly and side of his neck area. He lightly nibbles my fingers, turns his head and makes little noises. He also holds one finger with his foot and then uses the other to touch his neck in a way that reveals his pin feathers, almost like he is showing me where he needs help. Ha!
