Like teenage Romeos toting sticker-plastered guitar cases, male palm cockatoos show that romancing a crush with a love song isn’t just about music — it’s also about style.
Wild palm cockatoos (Probosciger aterrimus) craft bespoke instruments for musical mating rituals according to their individual tastes, researchers report September 13 in Proceedings of the Royal Society B. Some males were drumstick devotees, others made a mix of drumsticks and seed pod instruments, and one unorthodox male marched to the beat of his own pods — he made almost no drumsticks at all. These individual touches have more to do with personal preference than with available materials, the team found, hinting that these rockin’ cockatoos’ mates might prize creativity or individuality.
Adding distinctive touches to their instruments is not “a routine that is always the same in every animal,” says cognitive biologist Alice Auersperg of the University of Veterinary Medicine Vienna, who was not involved in the research. “There is some element of innovation to it.”
Unlike primates, most parrots aren’t known to use tools in the wild. And “most parrots that have been studied using tools have been studied in captivity,” Auersperg says. 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).
Wild palm cockatoos are a fabulous and fascinating exception. 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.
