For the most part they can be very noisy. Very hard to train a bird to be quiet. That's kind of like telling a cat not to purr.
Some are quieter than others, but you never know.
My bird loved it when the phone rang. She knew I would give her treats so she would be quiet. LOL They are very smart.
Birds can be very temperamental.
A macaw is a very large bird and could be a handful if you are not used to birds of that size. You have to be prepared to handle it.
