In brief

Cockatoos are crested parrots (family Cacatuidae) with 21 species across Australasia — intelligent and long-lived birds threatened by illegal trapping for the pet trade, with several Indonesian species Critically Endangered.

By the WARN Research & Conservation TeamChecked against IUCN Red List & CITES sourcesLast updated

Cockatoos are parrots of the family Cacatuidae, distinguished by erectile crests, often pale plumage and powder-down feather maintenance. Twenty-one species occur mainly in Australia, Indonesia and Oceania — from the familiar sulphur-crested cockatoo to the Critically Endangered yellow-crested cockatoo of Indonesia. Cockatoos are intelligent, social and among the longest-lived parrots. They are heavily trapped for the pet trade, especially in Indonesia and East Timor, where wild populations of several species have collapsed.

Key Facts: Cockatoo

  • Cockatoos are parrots with movable crests — they raise feathers when alarmed or excited.
  • Indonesia is a critical range country; trapping for export devastated yellow-crested and salmon-crested cockatoos.
  • Cockatoos are louder and more demanding than many parrots — unsuitable for typical flats or busy households.
  • Powder-down produces a fine dust that can trigger allergies; a consideration for captive care.
  • Palm cockatoo — largest cockatoo — uses tools to drum on hollow trees in courtship displays.
  • WARN links cockatoo welfare to broader parrot anti-trafficking work in Brazil and Colombia and education in Malaysia and Indonesia.

What is a cockatoo?

Cockatoos form a distinct branch of the parrot order native primarily to Australasia. Unlike many colourful parrots, most cockatoos wear white, black or pink plumage with striking crests. They lack the oil gland used by many birds for preening, instead producing powder-down that cleans feathers — visible as dust in aviaries. Genera include Cacatua (white cockatoos such as sulphur-crested and umbrella), Calyptorhynchus (black cockatoos of Australia), Callocephalon (gang-gang) and Nymphicus (cockatiel — the smallest cockatoo). Sizes range from the 30 cm cockatiel to the 60 cm palm cockatoo. Cockatoos pair bond strongly and roost communally. Large flocks of galahs or corellas can aggregate in agricultural landscapes, sometimes creating conflict with farmers — a management challenge distinct from endangered island species.

Intelligence, vocalisation and welfare

Cockatoos excel at manipulation: unscrewing fixtures, opening latches and destroying timber is common in captivity without enrichment. They learn screams and phrases, using loud contact calls natural to open woodland — behaviour that becomes problematic in apartments. Wild birds spend hours foraging, chewing bark and extracting seeds. Captive cockatoos need large aviaries, chewable branches and social partners. Single birds often develop self-mutilation and feather loss. Lifespans of 40 to 80 years mean rehoming crises when owners age or relocate. Sanctuaries report cockatoos among the most surrendered large parrots.

Trade and conservation

The yellow-crested cockatoo (Cacatua sulphurea) exemplifies trade-driven collapse: once common across Indonesia and East Timor, trapping for the cage-bird market reduced wild numbers by over 80 percent in three generations. The species is Critically Endangered, with fewer than 2,500 mature individuals. Similar patterns affect the salmon-crested cockatoo of the Moluccas. Australian black cockatoos face habitat loss as old-growth forest is cleared for agriculture; Carnaby's black cockatoo is Endangered. CITES lists most cockatoos on Appendix I, banning commercial international trade in wild specimens. Recovery requires nest guarding, export enforcement, community awareness and sustainable ecotourism. Captive breeding supplies legal birds but cannot replace wild populations without habitat security.

Cockatoos and people

In Australia cockatoos are cultural icons — sometimes celebrated, sometimes cursed for crop damage. In Indonesia they symbolise status and spiritual connection, which fuels demand despite legal protection. Responsible engagement supports accredited sanctuaries and rejects social-media markets selling unregistered birds. Tourists should avoid venues offering cockatoo photo ops tied to unknown sourcing. WARN's parrot appeal connects to cockatoo conservation through shared trafficking routes and welfare standards. Readers learning about cockatoos should explore the parrot hub guide and macaw pages for the wider Psittaciformes picture.

What WARN Does

WARN supports parrot anti-trafficking and rehabilitation in Brazil and Colombia and publishes free education reaching readers in Indonesia and Malaysia — key cockatoo range states. Confiscated parrots and cockatoos receive triage at partner centres; this guide explains why crested birds belong in forest canopies, not smuggler's crates.

If this guide helps you understand wildlife and the pressures it faces, a gift to WARN supports habitat protection and free public education in our partner countries.

Cockatoo: Frequently Asked Questions

How many cockatoo species are there?
Twenty-one living species in family Cacatuidae, including cockatiel, sulphur-crested, umbrella, palm and several black cockatoos. Most occur in Australia, Indonesia and nearby islands.

Are cockatoos parrots?
Yes. Cockatoos are a family within the parrot order Psittaciformes, alongside macaws, lorikeets and budgerigars. They are distinguished by crests and powder-down plumage.

Why are yellow-crested cockatoos Critically Endangered?
Intense trapping for the pet trade, habitat loss and persecution as crop pests reduced populations across Indonesia and East Timor by more than 80 percent. Fewer than 2,500 mature birds may remain.

How long do cockatoos live?
Large cockatoos commonly live 40 to 60 years in captivity, with some exceeding 80 years. Cockatiels are shorter-lived, often 15 to 25 years with good care.

Are cockatoos good pets?
They are demanding wild animals requiring space, noise tolerance and decades of commitment. Welfare experts caution that most households cannot meet their social and enrichment needs.

What is the largest cockatoo?
The palm cockatoo (Probosciger aterrimus) of New Guinea and northern Australia is the largest — up to about 60 cm long with a powerful bill used to drum on trees.

What do cockatoos eat?
Cockatoos forage on seeds, nuts, bark, fruit and native grains across Australia, Indonesia and Oceania. Wild birds spend hours chewing bark and extracting seeds. Twenty-one species in family Cacatuidae share this broad plant-based diet, though exact foods vary by species and season.

Where do cockatoos live?
Cockatoos occur mainly in Australia, Indonesia and Oceania, from open woodland and agricultural margins to forest canopies. Twenty-one species in family Cacatuidae range across Australasia, including the Critically Endangered yellow-crested cockatoo of Indonesia, where trapping for the pet trade has devastated wild populations.

Are cockatoos dangerous?
Cockatoos are not dangerous in the wild, though large species have powerful bills. Captive birds can bite severely if stressed. They are intelligent, social parrots with erectile crests and powder-down plumage, listed on CITES Appendix I for most wild-sourced trade. Several Indonesian species are Critically Endangered after population collapse.

How big is a cockatoo?
Cockatoo size varies across 21 species in family Cacatuidae. The palm cockatoo is the largest at up to about 60 cm long, while the cockatiel is the smallest at around 30 cm. Large cockatoos can live 60 to 80 years, making them among the longest-lived parrots.

Why Are Orangutans Endangered? Palm Oil, Deforestation and the Rescue Crisis in Borneo

Orangutans are endangered because of a single dominant cause: deforestation. All three remaining species have been reduced to small, fragmented populations in what remains of Borneo's and Sumatra's lowland and peat-swamp forests — and the crisis is getting worse, not better.

Borneo Deforestation and Palm Oil: The Wildlife Crisis in the World's Third Largest Island

Borneo is one of the most biodiverse places on Earth and one of the most rapidly deforested. More than half of the island's lowland forest has been lost in 40 years — a scale of destruction that has produced a permanent wildlife rescue crisis in Indonesia and Malaysia, two of WARN's partner-network countries.
