Cockatoos in Australia Are Teaching Each Other How to Loot Trash Cans [Sciencealert] "Before 2018, the results show these bin-opening skills of cockatoos were confined to just three suburbs of Sydney, each separated by quite a lot of distance. Yet after 2019, the technique had rippled out to 41 surrounding neighborhoods as well."
Yet not all the cockatoos tackled the trash bins in the exact same way. In the far north of Sydney, for instance, cockatoos might be more likely to walk around the right side of the bin while holding the lid, while in the center of the city, these birds might shimmy or hop with the lid on their head. Article includes embedded bin-opening videos and this non-bin-related link which is completely awwwwww.
It probably depends on whom the birds were imitating when they first learned the skill.
"Our results show that the spread of innovation can not only result in establishment of culture, but can also further lead to emergent geographically distinct subcultures," the authors write.
