Sulphur-Crested Cockatoo
Cacatua galerita · also called sulfur-crested cockatoo
In one Sydney suburb, a sulphur-crested cockatoo braces its feet on a garbage bin lid and flips it open with practised ease, extracting a scrap of food before flying off. A few streets over, another cockatoo does the exact same thing, having picked up the technique simply by watching.
Overview
The sulphur-crested cockatoo, Cacatua galerita, is a large, long-lived parrot native to Australia, New Guinea, and nearby islands. Its exceptional lifespan and documented ability to learn and spread new foraging techniques make it one of the more behaviourally remarkable parrot species.
A skill passed bird to bird
The spread of bin-opening behaviour across Sydney’s cockatoo population offers researchers a rare, clearly documented glimpse of cultural learning in the wild, with the specific technique varying slightly between suburbs depending on which bird first figured it out.
Status
Least Concern — widespread and stable across suitable habitat throughout Australia, New Guinea, and nearby islands.
Sulphur-Crested Cockatoo: common questions
How long does a sulphur-crested cockatoo live?
A sulphur-crested cockatoo can live 70 years or more in captivity, an exceptionally long lifespan for a bird that means individual cockatoos can genuinely outlive their original human owners, making long-term care planning an important consideration for anyone keeping one as a pet.
Is it true that cockatoos learned to open garbage bins from each other?
Yes, in parts of Sydney, Australia, sulphur-crested cockatoos have learned to flip open the lids of household garbage bins to access food waste inside, and researchers documented this specific technique spreading across different suburbs as birds learned it by observing other cockatoos, a genuine case of cultural transmission in wild birds.
Why does a sulphur-crested cockatoo raise its crest?
A sulphur-crested cockatoo raises its large, bright yellow crest of feathers to communicate mood and intent to other cockatoos, using the crest position alongside body language and vocalisations during display, alarm, and social interaction within its flock.
Where does the sulphur-crested cockatoo live?
The sulphur-crested cockatoo is native to Australia, New Guinea, and several nearby islands, generally found across forest, woodland, and open grassland habitat, where it forms large, noisy flocks, particularly outside the breeding season.
