Common Cockatoo Health Issues and What Causes Them

Common Cockatoo Health Issues and What Causes Them

Cockatoo health problems split fairly evenly between physical and behavioral, and this is genuinely one of the few species on this site where the behavioral issue is common enough to belong right alongside the medical ones. See our tank setup guide for the husbandry side of prevention.

Feather-Destructive Behavior (Feather Plucking)

Particularly prevalent in this species specifically, more so than in most other parrots. Watch for over-preening to bare skin, and in serious cases, self-mutilation. Causes include stress, boredom, loneliness, separation anxiety, and poor early socialization, though medical triggers like giardia or PBFD can also cause plucking and need to be ruled out first.

Always start with an avian vet visit to rule out a medical cause before assuming it's purely behavioral. Once medical causes are excluded, behavioral cases are managed through consistent enrichment, routine, and addressing the underlying social and emotional needs, not just treating the symptom. A steady rotation of destructible foraging toys is part of that enrichment picture, not a luxury add-on. Our deep dive on cockatoo screaming and feather plucking covers the psychology behind this behavior in far more depth than fits here.

Psittacine Beak and Feather Disease (PBFD)

A circovirus first described in Australian cockatoos, and white cockatoo species specifically are noted for beak malformations from this disease. Watch for abnormal or clubbed feathers, loss of the normal powder-down coating (a glossy-looking beak is a sign), and beak deformity.

This is incurable, often fatal, and highly contagious. Confirm with a vet through PCR testing, and quarantine any new bird before introducing it to an established one, this is genuinely important prevention, not excessive caution.

Lipomas and Obesity-Related Fatty Tumors

Common in overweight cockatoos, tied directly to high-fat, seed-heavy diets. Managed through vet guidance and genuine diet correction, a diet built around formulated pellets like Harrison's rather than seeds goes a long way toward prevention.

Hepatic Lipidosis (Fatty Liver Disease)

Also from seed-heavy overfeeding. Watch for an enlarged liver and changes in beak or nail keratin. Needs veterinary management.

Screaming and Behavioral Stress Disorders

Not a disease in the traditional sense, but a leading welfare concern and the top reason cockatoos get surrendered, a pattern our handling guide covers from the ownership side. Worth noting: a sudden change in a previously stable bird's vocal or behavioral pattern can also signal underlying pain or illness, not just an emotional or environmental issue, so a real change in behavior is always worth a vet visit to rule out.

The Husbandry Pattern Worth Remembering

A seed-heavy diet directly causes both the lipomas and fatty liver disease on this list. Insufficient social interaction and enrichment drive the feather-destructive behavior that's especially common in this species. And skipping quarantine for a new bird is how PBFD spreads. Diet, genuine daily engagement, and careful introductions do most of the preventive work here.
