Cage birds need toys to keep them busy and entertained. Buy some YOU like and see if your pet birds agrees. Especially your larger parrots can be very fussy and it is a good idea to experiment with various toys to establish their likes and dislikes.
If your bird is tame and allowed to be outside its cage, it is nice to have a stand with a perch or two which you can place at a convenient spot so as to enjoy the company of your pet. Some play stands make provision for food and water bowls and also some toys.
