The Beak’s Magic Trick

Standing on the edge of the bin, the cockatoo begins its heist by latching its sharp beak under the lid. This initial step is crucial for gaining leverage. The bird then uses its beak to start lifting the lid.

Mastering the Lid Lift

While holding onto the lid, the cockatoo walks along the edge of the bin. As it moves, it shifts its beak down the lid, lifting it higher. Finally, it flicks the lid over to reveal the trash inside.

The Brick Barrier

One clever resident tried to outsmart the cockatoo by placing a heavy brick on the lid. This was meant to keep the bird out. But the cockatoo wasn’t easily deterred.

Assessing the Situation

The cockatoo takes a moment to assess the new challenge. Using its beak, it probes the brick for weaknesses. It tries to pick up the brick with its beak on the top edge, but then changes tactics by wedging its beak beneath the brick.

Victory Over the Brick

The cockatoo then makes light work of the brick. Getting its beak under the brick, it pushes it slowly towards the edge, nudging it from different angles. After a few targeted tries, the cockatoo successfully pushes the brick off the bin.

Success!

Once the code has been cracked, the cockatoo is then ready for the final task—opening the bin. Using its trusty technique, it slides down the edge of the bin with the lid in its beak and flicks the lid open. The trash inside is now free for the taking.

Meet the Sulphur-Crested Cockatoos

Sulphur-crested cockatoos are large, white birds in the parrot family. They’re common in eastern Australia and usually live in wooded areas. As forests have been cut down, these birds have adapted to living near people.

Brainy Birds

Cockatoos, as parrots, are among the most clever birds. Despite having small brains, they have dense neuron-packed forebrains. This gives them cognitive abilities similar to great apes.

Punks of the Bird World

Cockatoos are the punks of the bird world, both in looks and character. Their yellow crests resemble mohawks, and their hopping, wing flapping, and head bobbing give them a devil-may-care attitude. Not only do their shrieking calls resemble a punk rock song, but these curious and destructive birds leave a trail of devastation during their inventive food raids.

Scientific Studies

Researchers from the Max Planck Institute studied the spread of the bin-opening technique. They inspected over 3,000 bins across four Sydney suburbs, filming 160 heist operations. Their findings have been published in scientific journals.

Learning by Watching

With more cockatoos turning into effective trash thieves, researchers wanted to learn how cockatoos were learning these techniques. Researchers found that this behavior spreads through social learning. Younger birds observe and imitate older, experienced ones.

Rapid Knowledge Spread

In early 2018, residents noticed that birds in three Sydney suburbs had mastered the technique. By the end of 2019, cockatoos in 44 suburbs were lifting bin lids. This rapid spread highlights the extent of their social learning skills.

Humans Adapt Too

People also adapted by sharing tactics to protect their bins. Streets within a few blocks often used similar methods, like bricks or straps. Neighbors learned these tricks from each other.

The Human-Cockatoo Arms Race

An “arms race” has developed between humans and cockatoos. Residents try various methods to secure their bins, but the birds often outsmart them. This ongoing battle requires constant innovation.

Securing the Bins

Residents use bricks, straps, and other objects to weigh down lids. Despite these efforts, cockatoos often find ways to get in. The clever birds keep adapting to new challenges.

Inventive Solutions

The challenge faced by residents is that they need to find a way to prevent the lid from being lifted while allowing it to open for trash collection. This has led to more creative methods to stop the birds. Bricks, pool noodles, spikes, and sticks are some examples.

Proven Tactics

Some methods work better than others. Hanging weights from the lid or wedging items through the bin’s back handles has been more successful. These higher levels of protection seem to deter the cockatoos, as they took too long to solve, forcing the cockatoo to find an easier target.

Ecological Impact

The cockatoos’ behavior impacts local ecosystems by scattering trash. This can attract other animals and pests to feed on the waste. Plus, it leaves a mess for the neighborhood to clean up to prevent the harmful effects of litter.

Urban Survivors
