My green cheek conure, my Quaker parrot, my Senegal parrot, and all of my 7 budgies love toys, doesn't matter what they are, they play all day long and are very good at entertaining themselves. My cockatiel on the other hand has never touched a single toy to the best of my knowledge. They have multiple large T-stands with toys hanging all over them as well as a huge PVC bird gym that has some really cool, large wood toys, puzzle toys, foraging toys, and even a bunch of the cheap, plastic budgie toys (my green cheek loves these), and they all love everything except for my cockatiel. She's content to just sit on top of her cage or on the perch she has on the outside of it and watch everyone else playing. I've tried everything, she just doesn't get it, or she gets it but doesn't care. I guess some birds are just like that.
