This Project promotes the preservation and better understanding of Palm Cockatoos in Australia. This Project, which I started in 2009, involving 33 months of remote fieldwork (as of May 2023), 6 scientific papers published (more in preparation), and myriad public engagement activities to increase the public profile of these magnificent birds. “I think being really individual and being creative and being out there on your own is part of what the females are looking for.Australia's largest parrot by weight, Palm Cockatoos are sadly Endangered, and they need our help. There are many “different ways of getting it right - of being a good artist, both in their musical performance, but also in the crafting of these tools,” he says. “Each one has developed his own idea as to what makes a special drumstick,” says Heinsohn. Some preferred short and stubby drumsticks, while others made longer, thinner ones. Drumstick length varied more from bird to bird than would be expected by random chance. Like a musician smashing a guitar at the end of a concert, male cockatoos toss their instruments to the ground after a display.Ĭomparing instruments discarded by 12 individual cockatoos revealed what the researchers interpret as evidence for individual preference in their instrument designs. This led the team to 70 display trees, where the scientists collected a total of 227 drumsticks and 29 seed pod instruments discarded by the birds. Over two years, the researchers wandered Australia’s Kutini-Payamu National Park and surrounding Aboriginal lands listening for the calls of displaying male cockatoos. Heinsohn and his colleagues wanted to see if these rocker birds express their singular style through their instruments, too. Some like to do it really slowly, some go very quickly, and then others throw in little flourishes.” “And the males all have their own drumming signatures. “Those tapping displays actually have all the hallmarks of human music using instruments,” says conservation biologist Rob Heinsohn of the Australian National University in Canberra. Appleby As part of their mating ritual, male palm cockatoos craft individualized percussion instruments - either sticks or seed pods - to drum against their trees. As part of their mating ritual, male palm cockatoos craft individualized percussion instruments - either sticks or seed pods - to drum against their trees. Add in the birds’ dramatic black and red plumage and tall, spiked crests and you’ve got perhaps the closest nature can come to a rock concert. As part of the display, he crafts the instrument himself and the female watches as he snaps off tree branches and whittles them just so. He sings, twirls and drums rhythmically against the tree, often using a percussion instrument, a stick or seed pod, clutched in his left foot ( SN: 6/28/17). These striking, endangered birds live in parts of northern Australia and New Guinea, and they craft and use tools not to find food, but to find a mate - a rarity that stands out even in primate company.Ī male palm cockatoo puts on a musical mating display from trees in his territory. Wild palm cockatoos are a fabulous and fascinating exception. For instance, her team found that wild-caught Goffin’s cockatoos ( Cacatua goffiniana) held temporarily in a research aviary, wielded sophisticated toolkits for foraging ( SN: 2/10/23). And “most parrots that have been studied using tools have been studied in captivity,” Auersperg says. Unlike primates, most parrots aren’t known to use tools in the wild. Like us and our primate cousins, parrots have big, clever brains, complex social lives and extended childhoods spent learning from their parents. If humans were birds, we might be something like parrots.
