So, many trainers have gone to using a stick instead of a hand from which the parrot can learn commands. You'll want to decide whether you'll use stick training early on, though, as you don't want it to think your hand is not a good place to sit.

Use one-syllable words, when possible. This noise reminds parrots of the sounds its natural enemies make in the wild. It may cause your parrot to grow frightened. You may want to hold your parrot next to your body while training it. While some people think it's okay to train parrots while they sit on their shoulders, it can have a detrimental effect later.
