What Is a Cockatoo?

Check out this answer from Consensus:

Cockatoos are fascinating birds with complex behaviors and specific dietary and health needs. They are not only popular pets but also subjects of scientific research due to their unique physiological and behavioral traits. Understanding these aspects can help in providing better care and management for these vibrant birds.

Cockatoos are a group of birds belonging to the family Psittacidae, known for their distinctive crests and vibrant personalities. They are native to Australia, Indonesia, the Philippines, and surrounding islands. This article explores various aspects of cockatoos, including their behavior, physiology, and common health issues.

Physical Characteristics

Cockatoos are easily recognizable by their prominent crests, which they can raise or lower at will. These birds vary in size and color, with some species like the Sulphur-crested Cockatoo (Cacatua galerita) being particularly well-known for their striking appearance4. They have strong, curved beaks and zygodactyl feet, which means they have two toes facing forward and two backward, aiding in climbing and handling food.

Behavior and Diet

Cockatoos are highly social and intelligent birds, often seen engaging in playful activities. They require a varied diet to meet their nutritional needs. A study on the feeding habits of the Sulphur-crested Cockatoo showed a preference for corn and sunflower seeds, with pellets also being a significant part of their diet4. Their daily activities predominantly include perching, which accounts for a large portion of their time4.

Health and Medical Research

Cockatoos, like many other birds, can suffer from various health issues. Feather picking disorder is a common problem, and research has shown that clomipramine can be effective in treating this condition, significantly improving symptoms over a few weeks2. Additionally, studies on the physiological responses of cockatoos to certain drugs have been conducted. For instance, the administration of vecuronium has been found to cause significant pupillary dilation with minimal side effects, making it a potentially useful mydriatic agent for avian species1.

Hormonal Studies

Research into the hormonal responses of cockatoos has revealed interesting findings. For example, the administration of adrenocorticotropic hormone (ACTH) in Moluccan Cockatoos (Cacatua moluccensis) significantly increased serum corticosterone levels, indicating a strong physiological response to stress3. This study also highlighted potential differences in hormonal responses between male and female cockatoos3.
