Cockatoos belong to the family Cacatuidae — the only family in the superfamily Cacatuoidea — and represent one of the most distinct branches of the parrot order Psittaciformes. Together with the true parrots (Psittacoidea) and the large New Zealand parrots (Strigopoidea), they form the three major lineages of all living parrots.

The family has a primarily Australasian distribution, ranging from the Philippines and the eastern Indonesian islands of Wallacea east through New Guinea, the Solomon Islands, and across Australia. The name “cockatoo” derives from the Malay word kakatua — itself likely from kakak (older sibling) and tua (old), or from kaka (parrot) and tua (old).

What immediately sets cockatoos apart from other parrots is the crest — a dramatic fan of feathers that rises and spreads in direct response to the bird’s emotional state. Combined with expressive body language, a remarkable capacity for bonding, and an astonishing volume when they decide to use it, cockatoos are in a category of their own among companion birds.

Many experienced bird keepers describe life with a large cockatoo as living with a perpetual two-year-old child — one capable of spectacular temper tantrums, bottomless affection, infectious silliness, and the occasional act of deliberate destruction. Cockatoos are cognitively and emotionally complex, deeply social, and genuinely high-maintenance. They are also, for the right person in the right home, among the most profoundly rewarding companion birds on earth.

HFFN sees more cockatoos surrendered to rescue than almost any other species. Understanding why — and whether a cockatoo is truly right for your life — is the most important thing a prospective owner can do before bringing one home.

Cockatoos are often called “velcro birds” — and the name is earned. A cockatoo that has bonded to a person does not merely want to be near them; it wants to be on them, as much as possible, for as long as possible. This level of attachment is genuinely touching, and it is also genuinely problematic if a keeper cannot honor it consistently.

The cockatoo’s extraordinary social intelligence evolved in the context of wild flock life — constant companionship, shared foraging, communal roosting, and lifelong pair bonds. In captivity, the keeper becomes the flock. When that flock disappears — even just into the next room for too long — a poorly managed cockatoo responds with the full repertoire of wild distress behavior: screaming, feather destruction, and sometimes outright self-mutilation.

The key to a well-adjusted cockatoo is not giving it unlimited attention — it is teaching it, from the very beginning, to tolerate time alone and to entertain itself. A new cockatoo should not be showered with non-stop contact. That creates a bird that cannot cope without constant stimulation, which leads directly to the screaming, feather-picking, and behavioral problems that cause so many cockatoos to end up in rescue.

Boundaries must be established early and maintained consistently. A cockatoo that has learned to entertain itself with foraging toys and enrichment activities, and that has been taught that quiet behavior — not screaming — gets attention, is a dramatically happier and more manageable bird.

Cockatoos are also intensely physically demonstrative. They lean into head scratches, drape themselves over shoulders, and preen their person’s hair with enthusiasm. Some become sexually imprinted on their keepers as they mature and require careful management of that dynamic.

There is no gentle way to say this: large cockatoos — particularly Moluccans, Umbrella, and Sulphur-crested — are capable of producing contact calls that exceed 130 decibels. That is in the range of a chainsaw or a jet engine at close range. They are, without question, the loudest companion birds kept in captivity.

Contact calls — the scream a cockatoo produces when it cannot see its flock mate — are instinctive and essentially impossible to eliminate entirely. They can be managed with training, routine, and environmental design, but they cannot be removed from the bird’s behavioral repertoire. A household considering a large cockatoo must be honest about whether their living situation can accommodate this.

In Hawaiʻi, where homes tend to be close together and landlords are already skeptical of birds, a screaming cockatoo is one of the most common reasons for forced rehoming. HFFN takes this seriously in our adoption screening process. We will ask directly about your housing situation, your neighbors, and your realistic tolerance for noise before placing any large cockatoo.

A cockatoo’s cage is the most physically demanding cage purchase in aviculture. These birds are powerful and persistent, and they will systematically test every weld, latch, bar, and screw. A poorly constructed cage will not contain a determined large cockatoo. Look for stainless steel or heavy-gauge powder-coated steel with welded rather than twisted wire, and locks that require two separate movements to open.

Outside the cage, cockatoos chew — constantly and enthusiastically. This is not bad behavior; it is a core biological need. Wild cockatoos spend significant portions of their day using their bills on wood, bark, seed pods, and vegetation. In captivity that need must be redirected with a steady rotation of appropriate chew items: untreated softwood blocks, palm fronds, leather, cork, and similar materials. A cockatoo without appropriate chew opportunities will find its own: baseboards, door frames, furniture, window moldings.

Diet should be based on a high-quality formulated pellet (approximately 60–70% of intake), supplemented with a wide variety of fresh vegetables, limited fruit, and very limited seed and nut. Feeding should involve foraging elements — hiding food in toys, wrapping it in palm fronds, presenting it in ways that require effort. Wild cockatoos forage for seeds, tubers, corms, fruits, flowers, and insects across large territories; that drive does not disappear in captivity.

Cockatoos are prone to obesity on seed-heavy diets, particularly Moluccans and Umbrellas. A diet too high in fat contributes to fatty liver disease, a leading cause of premature death in captive cockatoos. Sunflower and safflower seeds should be occasional treats, not dietary staples. Out-of-cage time should be generous and daily — several hours minimum — with play gyms, climbing structures, and rotating enrichment.

Cockatoos — particularly large white cockatoos — are among the most surrendered birds in rescue worldwide, and Hawaiʻi is no exception. They are surrendered because they scream. They are surrendered because they bite. They are surrendered because a landlord said no. They are surrendered because an owner became ill, or divorced, or died. They are surrendered because someone fell in love with a beautiful white bird without understanding what forty years of that bird’s needs would actually look like.

HFFN does not say this to discourage adoption — we say it because honesty about why birds come into rescue helps potential adopters prepare for what they are taking on. A rescue cockatoo is not a blank slate. It has a history, and that history shaped who it is. Some have behavioral challenges that require experienced, patient, and deeply committed hands. Some are remarkably well-adjusted birds that simply lost their families through no fault of their own.

What all rescue cockatoos need, without exception, is consistency, patience, appropriate enrichment, and a home that truly understands what they are. HFFN screens cockatoo placements with particular care. We ask hard questions about housing, noise tolerance, prior experience, and household stability — and we are honest when we think a match is not right.

If you believe a cockatoo is right for your life, the best first step is to come to an HFFN meeting and spend time around our members’ birds. No amount of reading substitutes for that experience.
