Love this user manual! Oliver the BF used to do something slightly different. He had a cage with a large wood, rimmed platform on top. Every now and then he went into wiggy mode. Feathers slicked tight. Head bent forward and turned sideways. Shoulders raised, but wing tips crossed tight behind his back making a perfect heart shape. Then he goes in circles sound the top of his cage. I interpreted this as "Be afraid. Be very afraid."
A similar behavior was to bend his head down, apply the top of the beak to the wood tray, and drag the beak around the edge of the tray making a scraping noise. I translated this as "MY. SPACE. If you attempt to interfere you are clearly insane and need bitin'." I haven't seen these behaviors described anywhere - has anyone else seen their Amazon do this?

On a nice note, he knew how to drive. Lift foot, ask for pickup, lift foot and point palm in the desired direction. Put foot down as human totes you in that direction. Stop and look out window, behind door, etc. as desired. When ready to move on, lift foot again to indicate direction. When approaching a final destination such as favorite perch, lean forward, quiver wings, rapidly lift foot, point, put foot back down. Repeat all these actions as rapidly as possible. When close enough, leap onto perch, turn, and growl at human. Rest assured that human enjoys playing parrot taxi and will come running when it's time to move on.
