Cape York Peninsula’s Palm Cockatoo – Australian Geographic. Sexual maturity is reached between 7 and 8 years of age.īurnie, D., 2011. Animal. Survival rates are incredibly low, only 60% of eggs will hatch and 40% of these will make it to adulthood. Young will typically remain close to their parents until the next breeding season. This is the longest parental care provided by any parrot. It will take 100 days for them to fledge. The male is primarily responsible for finding food. At hatching the chick will have no feathers and rely entirely on the parents for its care.įemales do most of the incubation with some assistance from the male. Inside the hollow they form a platform of twigs.Ī single egg is laid in the nest. Males will engage in fights over a nesting site. Pairs appear to be monogamous and will typically mate for life. Most nests are located in woodlands.īreeding takes place from August to January though there is some slight local variations in this. The palm cockatoo will make its home in rainforests, dense savanna and woodlands. In Australia the palm cockatoo is found only in Queensland in the upper portion of the Cape York Peninsula. However, Heinsohn and his team did not examine the females' reactions to the males' music.Palm cockatoos can be found throughout Australia and New Guinea along with a range islands around this region. ( Read about weird courtship and mating rituals.) “Their cheeks go red when sexually excited," Heinsohn says, noting a certain the lack of subtlety in their motives. The males also frequently combined their drumming with a vocal and visual display. Importantly, males primarily started drumming when they were around females-about 70 percent of the time, according to the research, published this week in the journal Science Advances. (See " Whistling Caterpillars And 5 More Surprisingly Musical Species.") Rockatoo And each male Heinsohn observed banging a rock or stick had a unique, yet discrete, musical style. Intrigued, Heinsohn spent the next two decades videotaping the shy animals to find out if their drumming is truly music-defined as regular beat production, repeated components, and of course, personal flair.īy analyzing the sequences of the beats made by the birds, Heinsohn and colleagues found the sounds were highly predictable, just like human music. “The cockatoo was clutching what looked like a stick and banging it on the trunk, and every so often he would pause, erect his amazing crest, and let out either a piping whistle or a harsh screech,” says Heinsohn, who received funding for his research from the National Geographic Society. Robert Heinsohn, a conservation biologist at Australia National University, first witnessed the behavior in male birds in northern Australia in 1997.

The Australian bird is the only animal other than humans known to use a custom-made tool to tap out a percussive beat, a new study says. Male palm cockatoos just might be the rock stars of the animal kingdom-but unsurprisingly, they mainly just do it for the chicks.
