A beak is used to seek. Don't be confused, we will taste your wall one day.
If you were expecting a parrot to act like a person and not taste your wall, you are confused. We have a beak, it's used to seek! And all those toys you are buying, may or may not keep us from tasting your wall, or chair, or couch, or table, or lamp or, picture frame, or faucet, or carpet or book or...well, you get the picture.
