Relax you have only had Star a short time. I'm sure he is just regrouping and getting use to his new surroundings. When I got my Ana Grey at 4 months old, I took her around to all the windows, glass doors and mirrors and just tapped them so she could see that they were solid. I also have decals on my patio door and larger windows. I occasionally remind her of the windows once in awhile. Leave the cage door open and sit down and talk to Star, he'll get curious and come out, just wait and see. You are going to be a great parront, just be patient.
