Years ago I knew a couple that had a blue and gold Macaw that they had to take EVERYWHERE with them. They didn't keep him in a cage and if they left him home alone he would get pissed off and tear things apart. One time he did about $1500 worth of damage, ever since then he was always on the shoulder Elliot was his name and he was huge. Saw him break a 3/4" dowel rod in half like it was a pencil.
