Agree completely. I have had one caique for over 12 years and had another one for 6 years until he passed away, both from the rescue. Caiques are notorious for going after other birds, animals, people that they don't like, regardless of the size difference. Mine once went after a doberman and luckily I could intervene in time. He'll still occasionally go after my timneh (who is twice his size). Be very, very careful. It's far too easy for a beak or toe to be bitten off.
