You're speaking to Dr. Michael Salkin. Welcome to JustAnswer. I'm currently typing up my reply.
I'm sorry that your question wasn't answered in a timely manner. We don't have many avian vets on this site. Please let me know if you still need help. Your cockatoo's behavior isn't pathognomonic (specifically indicative) of any one particular disorder and may represent normal parrot behavior rather than disorder. Have any other symptoms arisen since you posted?
