Wild Kibatan Downunder learned how to open the lid of a residential trash can and plunder leftovers, a new study discovered. And apparently the birds are learning this trick from each other.
A bird in a distant neighborhood invented another technique to open the lid. It soon spread to a nearby suburban parrot.
“We observed that birds do not open trash cans in the same way, but in the suburbs differently, suggesting that behavior is learned by observing others. Barbara Crump, principal investigator, said at the Maxplank Institute for Animal Behavior in Radolfzel, Germany. Said in a statement..
Kibatan (Cacatua galerita), Aboriginal people in eastern Australia are big-headed, long-lived and very social Parrot, The researcher said. A few years ago, Richard Major, a senior researcher at the Australian Museum Institute and a research collaborator studying the effects of urbanization on birds, showed a friend a video of a parrot opening a trash can in a house. It was. In the video, the parrot opens the lid with his beak and feet, shuffles to the side and flips the lid over to access the garbage buffet.
Lucy Apriln, a major friend and senior author of the study, a research group leader at the Max Planck Institute for Animal Behavior, was amazed at the behavior of the birds and Crump. “It was very exciting to observe such an original and innovative way to access food resources. We soon realized that we needed to systematically study this unique foraging behavior. I knew it, “said Crump.
Did the team learn how birds open this trash can through social learning? GeneticsSo they sought the help of the masses. During the 2018 and 2019 online surveys, scientists asked residents of the Sydney and Wollongong areas to record when and where they observed parrots opening their household trash cans.
“Australia’s trash cans have a uniform design across the country, and Kibatan is common throughout the East Coast,” said John Martin, a research collaborator at the Taronga Conservation Society, in a statement. “The first thing we wanted to know was whether parrots had trash cans everywhere.”
The team received 338 reports of parrots opening trash cans from 44 suburbs. In 93% of those reports, multiple parrots were observed, “emphasizing ample opportunity for birds to observe the opening of the bottle,” the researchers wrote in the study.
A map-based analysis revealed that the practice was likely to have started in three suburbs of Sydney, where people remember seeing the practice before 2018. As the parrots began to open the trash can, practice spread faster to parrots in neighboring areas than in distant areas. , Suggests that behavior has learned socially.
“These results show that the animals actually learned their behavior from other parrots nearby,” Crump said.
Researchers then painted the parrot at a hotspot that opened the three trash cans identified in an online survey. At Stanwell Park in Wollongong, New South Wales, 114 birds were marked and 36 birds tried to open the trash can, but only nine were successful. Researchers found that both boys and adults opened the trash can, and most of the birds that tried to open the trash can were men. Other birds waited until they lifted a heavy object before joining the feast at a feast of garbage.
It’s unclear why men are more likely to open the trash can than women, but researchers say that male parrots tend to be heavier and predominant and may be stronger than females. Alternatively, researchers were often more willing to “request” bottles, as researchers often saw parrots kicking their companions out of the trash can.
Aum’s video footage also revealed that opening the trash can is a complex, multi-step process that can be done in a variety of ways. In different regions, there appear to be different subcultures on how these birds open their lids, which researchers say is further evidence that this behavior is being learned rather than genetically. It was.
The study was published online in the journal on Thursday (July 22nd). Science..
