10 Surprising Cockatoo Facts

Cockatoos are famous for being loud, affectionate, and difficult to keep, but the biology behind that reputation is more interesting than the reputation itself.

1. Wild cockatoos pass tricks around like a fad. In Sydney, sulphur-crested cockatoos learned to flip open household wheelie bins. Before 2018 the behavior was reported in three suburbs; within about two years it had spread to 44, moving into neighborhoods next to ones where birds already did it. Each area developed its own lid-opening style, and fewer than ten percent of birds learned the trick, with the rest moving in once a pioneer had the lid open. Researchers read it as a foraging culture spread by social learning.

2. One cockatoo demonstrated real rhythm to a beat. A sulphur-crested cockatoo named Snowball became a genuine subject of cognitive science research after demonstrating the ability to synchronize movement to a musical beat, a rare documented example of rhythmic entrainment outside humans. A 2019 follow-up filmed him to two 1980s songs and counted 14 distinct dance movements and two combinations, from head-banging to body rolls, none of them trained.

3. Their contact calls can carry over a mile through dense forest. In the wild, loud vocalizations serve a real function: keeping scattered flock members aware of each other's location across thick canopy, not just noise for its own sake. Placing a bird by ear before you ever see it is one of the harder skills in birdwatching.

4. They have a retractable crest used for communication. The crest goes up when a cockatoo is excited, alarmed, or displaying, and lies flat during calm, relaxed moments, a visible mood indicator keepers learn to read quickly.

5. Their beaks are strong enough to bend metal. Cockatoos can crack extremely hard nuts in the wild, and in captivity that same bite force is capable of bending or working open standard cage latches, which is why dedicated cage locks are often necessary.

6. Some wild cockatoos use tools. Goffin's cockatoos have been observed making and using tools to extract seeds from fruit, a level of tool use that's rare among birds and was documented relatively recently in scientific literature. They also understand tool sets. In a 2023 study, six of ten Goffin's cockatoos learned to use a pointed stick to pierce a barrier and a split straw to fish out a cashew, and they carried both tools along whenever the box had a barrier but only one when it did not. The only other animal known to use tool sets like this is the chimpanzee. Crows are the other headline case of birds crafting their own tools.

7. They're found naturally only in Australia and nearby islands. Unlike many other parrot families with a broad tropical range, cockatoos (family Cacatuidae) are native only to Australia, New Guinea, and surrounding Indonesian and Pacific islands.

8. They can live 40 to 60 years or more. Cockatoos are among the longest-lived commonly kept birds, meaning many owners need a real plan for the bird's care well into the future. The record belongs to Cookie, a Major Mitchell's cockatoo at Brookfield Zoo near Chicago, who was at least 82 years old when he died in 2016. Guinness lists him as the oldest parrot ever.

9. Wild cockatoos typically mate for life. Paired cockatoos share nesting and parenting duties over years of partnership, a long-term bond that mirrors the intensity of the attachments they form with human keepers in captivity.

10. Jealousy toward other pets or family members is a documented behavior. Because cockatoos bond so intensely with a primary person, many show clear jealousy-like behavior when that person's attention goes to another pet or person.

Snowball the dancing cockatoo is the one I bring up in conversation more than I probably should. What surprised you most? Let me know below.
