Hard to believe but he has learned the difference between holding on biting hard. It only took 4 months! I'm in shock,he was so sweet today.He will let me do anything to him.Yesterday he took a shower w me an loved it!I couldn't get him off me yesterday he just wanted to be on me all day so when I got in the shower I put him on the towel rack left the shower curtain open and he flew into my head he loved it.So folks if uhave a tricky Mexican Parrolet,don't give up just takes time.
