Parrots vary considerably by size, care needs and temperment. So ... for instance  parakeet would need completely different pet bird supplies than an African Grey Parrot. Even our two species of African Grey Parrots need different sized supplies.  Our Congo, Smokey, is bigger all around.  He chews bigger toys, needs bigger perches and needs a bigger bird bed. Our Timneh, Timmy, on the other hand, becomes a little overwhelmed with a thicker  bird perch that Smokey would enjoy.
