WASHINGTON \u2014 A few years ago, a Sydney scientist noticed a sulfur-crested cockatoo opening his trash bin. Not every resident would be thrilled, but ornithologist Richard Major was impressed by the ingenuity.<\/p>\n

It\u2019s quite a feat for a bird to grasp a bin lid with its beak, pry it open, then shuffle far enough along the bin\u2019s edge that the lid falls backward \u2014 revealing edible trash treasures inside.<\/p>\n

Intrigued, Major teamed up with researchers in Germany to study how many cockatoos learned this trick. In early 2018, they found from a survey of residents that birds in three Sydney suburbs had mastered the novel foraging technique. By the end of 2019, birds were lifting bins in 44 suburbs.<\/p>\n

\u201cFrom three suburbs to 44 in two years is a pretty rapid spread,\u201d said Major, who is based at the Australian Museum.<\/p>\n

The researchers\u2019 next question was whether the cockatoos had each figured out how to do this alone \u2014 or whether they copied the strategy from experienced birds. And their research published Thursday in the journal\u00a0Science<\/a>\u00a0concluded the birds mostly learned by watching their peers.<\/p>\n

\u201cThat spread wasn\u2019t just popping up randomly. It started in southern suburbs and radiated outwards,\u201d said Major. Basically, it caught on like a hot dance move.<\/p>\n

Scientists have documented other examples of social<\/a> learning in birds. One classic case involves small birds called blue tits that\u00a0learned<\/a>\u00a0to puncture foil lids of milk bottles in the United Kingdom starting in the 1920s \u2014 a crafty move, though less complex and physically demanding than opening trash bins.<\/p>\n

But observing a new \u201ccultural trend\u201d spreading in the wild \u2014 or suburbs \u2014 in real-time afforded the cockatoo researchers a special opportunity, said Lucy Aplin, a cognitive ecologist at Max Planck Institute of Animal Behavioral in Germany and co-author of the study. \u201cThis is a scientist\u2019s dream,\u201d she said.<\/p>\n

During the summer of 2019, trash-collection day in suburban Sydney was the team\u2019s research day. As garbage trucks rolled down their routes and people shoved bins to the curb, Max Planck Institute behavioral ecologist Barbara Klump drove around and stopped to record cockatoos landing on bins. Not all cockatoos succeeded in opening them, but she took around 160 videos of victorious efforts.<\/p>\n

Analyzing the footage, Klump realized the vast majority of birds opening bins were males, which tend to be larger than females. The birds that mastered the trick also tended to be dominant in social hierarchies.<\/p>\n

\u201cThis suggests that if you\u2019re more socially connected, you have more opportunities to observe and acquire new behavior \u2014 and also to spread it,\u201d she said.<\/p>\n

Cockatoos are extremely gregarious birds that forage in small groups, roost in large ones, and are rarely seen alone in Sydney. While many animals have declined with the expansion of Australian cities, these bold and flamboyant birds general<\/a>ly have\u00a0thrived<\/a>.<\/p>\n

\u201cIn an unpredictable, rapidly changing environment with unpredictable food sources, opportunistic animals thrive,\u201d said Isabelle Laumer, a behavioral researcher at the University of California, Los Angeles, who was not involved in the research.<\/p>\n

Over the past decade,\u00a0research<\/a>\u00a0has shown that \u201curban adaptability is correlated with traits like innovativeness, behavioral flexibility and exploration,\u201d said Max Planck Institute\u2019s Aplin. What the new research adds to that understanding is that critters that easily transmit knowledge and new skills socially also have an advantage.<\/p>\n

Parrots \u2014 which include cockatoos \u2014 are known for being among the most clever birds. They have a brain just the size of a walnut, but the density of neurons packed into their\u00a0forebrains<\/a>\u00a0gives many species cognitive abilities similar to great apes, said Irene Pepperberg, an animal cognition researcher at Harvard, who has studied\u00a0African grey parrots<\/a>\u00a0and was not involved in the new paper.<\/p>\n

While African grey parrots are known for their ability to mimic and sometimes comprehend<\/a> human speech, cockatoos are famously adept at using and manipulating new tools, such as puzzle boxes in the lab or trash bin lids in the wild, she said.<\/p>\n

\u201cEveryone in Sydney has an opinion about cockatoos,\u201d said the Australian Museum\u2019s Major. \u201dWhether you to love to watch these big flamboyant social birds, or think they\u2019re a pest, you have to respect them. They\u2019ve adapted so brilliantly to living with humans, to human domination of the environment.\u201d\n <\/p><\/div>\n
