Hi. THe tricks a parrot can learn are limited only by your imagination. SPin is a good one to progress to. Shake hands, wave hello, spreading wings, nodding head yes or no, are all low impact tricks that are fairly easy to teach. You can greatly expand this by using props for the parrot to work with. Small wiffle balls are good props to start with, they are easy for beaks to hold and they can be trained to play fetch with them, or play basket ball. A good place to find cheap props is the infant section of large toy stores. Things like rings and rattles and other toys can be adapted. Buying parrot specific toys off the web can get pricey, so check the various sites for ideas, then search the web for the same item from a regualr seller. Example - small desktop magnetic dart board is $24 at one parrot site, but the same thing is $2 from a regualr vendor.
Set up a training area, and a specific time to do training, parrots love regularity. I think you will find Precious will be eager when it comes Training Time.
