I'm still working on Sophie with the shoulder thing. I try to keep her from it and she sneaks around my hands. If Cocoa is jumpy, take the time to sit down and do some "in the face time". I cuddle Sophie on my chest and talk to her in a calming quiet voice. After 15 minutes she is a much calmer bird. If you are taking Cocoa out of the cage, you generally have time to spend with him anyways. Good luck!
I have new markings on each ear from her being excited and getting on my shoulder. :p
I never said that Sophie wasn't a challenge, now did I?
