Since I keep flying at the window over and over again, my family asked an expert on raising baby Greys what to do about it. They thought that after I bumped my head a couple of times, I would stop hurting myself. Do you know what he said? He explained I won't learn it at all! He said they have to put something in front of the window or I could get myself killed one day. Now, they lower the lamellas every time I come down. You have to make some sacrifices if you live with a parrot.
