Is he rubbing his beak on the bars really fast?What is Sammy doing? He has done this several times and I don't know what it means. He crouches down and his wings shake a bit. He does it most when my husband talks to him or when he watches videos of other amazons. Is this normal amazon behavor?
No, he just holds onto the bars with his mouth.
Maybe he wants you to pet him or scratch his head. I've learned to take advantage of times when Whisper's beak is otherwise entertained than in position to bite me.
