A few yellow-billed cockatoos who fended off diving tricks actually taught their peers how to get food.

Sydney ornithologist Richard Major watched the yellow-billed cockatoo (Cacatua galerita) opening trash cans in the city. In a 2018 study conducted jointly with German researchers, a population survey revealed that birds are also using an unusual technique in three suburbs of Sydney. By the end of 2019, the animals had already looted litter boxes in 44 suburban areas.

Experts have been wondering whether the birds figured out what to do on their own or learned from more experienced individuals. the Sciences According to their study in the Scientific Journal, they concluded that birds learned to litter from their peers.

Garbage collection has long been the research day for researchers in the summer of 2019. As a garbage truck rolls through the streets and people push their trash cans onto a street corner, Max Planck Institute researcher Barbara Clamp noticed cockatoos landing on the trash cans. Not all birds were able to open the lids of the boxes, but the expert managed to make about 160 videos of successful experiments.

During the analysis of the recordings, it was found that most males succeeded in the operation more than females. Successful birds were also dominant in the hierarchy. “This suggests that the more social relationships you have, the greater your chances of observing, learning, and then spreading new behaviors,” Clamp believes.

Parrots are particularly social birds that always feed in smaller groups, spend the night in larger groups and are rarely seen in Sydney alone. While the numbers of many animal species have declined as a result of the spread of Australian cities, these bold and adorable birds tend to thrive.

Parrots, including cockatoos, are among the smartest birds. Although their brains are only about the size of nuts, their forebrains are so densely intertwined with neurons that many of their cognitive abilities are similar to those of humans.
