There are many mental stimulating toys for birds to forage. I on the other hand- make my own. You can put a few treats in a wax-free paper tea bag, fold it so it closes, and hang it up in his/her cage, or give it to her/him as a foot toy! You can also take a very small cardboard box, put a few teats in it and hang it up in your parrots cage. But make sure your bird knows that their are treats in it.
