Slender-billed Corellas are still rare as human companions but the few I have met have been absolutely charming and gregarious birds. They have also been quite beaky but, from my experience, they are playful and not aggressive. I spent some time playing with a young Slender-bill when I gave a program at Bird Paradise and beak exploration was an essential part of her play. She was an absolutely terrific bird who made me want to bring her home with me. She provided me with extreme delight watching her play with her head upside down most of the time. I also stayed at the home of a woman with a Slender-bill and was impressed with the playfulness of her bird. The cockatoo was really fun to watch.
Some people proclaim that the Slender-billed Cockatoo is the best talking parrot-family bird and the ones that I have observed have had extensive vocabularies. Slender-bills can be very enthusiastic and playful especially with human interaction. One that I met loved to play catch and fetch with her caregiver. Slender-bills (or Long-billed Corellas as they are often called) are incredibly inquisitive so they need to be supervised when they are out of their cage. They can also be quite stubborn so they need a caregiver who can provide guidance and provide them lots of stimulation and activity to keep their intelligence occupied. When I was in England to do a seminar, I got the impression that these highly social cockatoos were more available and more popular as companions there than here in the United States and the people who had them could not say enough good things about them. Note: If a bird of this description has no band of red feathers on the front of the neck, the bird is most likely a Western Corella (Cacatua pastinator)
