Behavior/Health Concerns:  A stressful household or a lack of the appropriate amount of human interaction can cause bad behavior in these somewhat high-strung pet birds. Sulpher-crested cockatoos also need a range of activities to keep them busy when they are not interacting with humans. If they are not given adequate chewing toys, they will find household items to chew. While these pet birds need attention and time with humans, they must also learn how to be independent and not become accustomed to an excessive amount of human attention. This pet bird does best in a home where it is the only bird. Sulpher-crested cockatoos can become territorial once they have matured and they are often destructive chewers. Without enough mental and physical stimulation, they can resort to destructive behaviors such as feather picking. They are susceptible to psittacine beak and feather disease (PBFD), fatty liver disease, obesity and bumblefoot. Sulpher-crested cockatoos are known to be dusty birds, and which is a concern for those with allergies.
