The land is being cleared for the mining of a mineral called bauxite. Lowland in New Guinea found in rainforest, forest edge, monsoon woodland, tall secondary growth. On the west coast, a lot of palm cockatoo habitat is being lost to broad-scale clearing. stenolophus: Japen Island in Geelvink Bay, Irian Jaya, and N New Guinea from Mamberamo River east to Collingwood Bay, SE Papua New Guinea. goliath: W Papuan Islands, except Misool, Indonesia, and C New Guinea from Vogelkop, Irian Jaya, east to SE Papua New Guinea. macgillivrayi: S New Guinea between Fly and Balim Rivers, and Cape York Peninsula, N Queensland, Australia, south on east coast to Princess Charlotte Bay and on west coast to Edward River aterrimus: Misool, in W Papuan Islands and Aru Islands, Indonesia. A low reproductive rate in Australia suggests that the species is at risk long-term. Is hunted for food in New Guinea and possibly Cape York, with high rates of nestling predation in Papua New Guinea. Increasing numbers of bush fires are contributing to the loss of suitable nest trees. Ongoing habitat loss and illegal trapping for trade are the main threats. Higher pitched than Sulphur-crested Cockatoo. stenolophus: Both adults as in goliath but crest feathers much narrower.Īs in adults but with pale yellow edging to feathers of underparts shorter crest. goliath: Both adults as in macgillivrayi but larger in size. The bare red patch on the Palm cockatoo’s cheek can change color, depending on their health or stress level. This powerful bill means that palm cockatoos can eat very hard seeds and nuts that are difficult for other species to deal with. macgillivrayi: Both adults as in aterrimus but larger in size. Fun Facts for Kids The Palm cockatoo has the largest bill of any parrot except for the hyacinth macaw. aterrimus: Both adults in general black with powder from down giving a grey appearance crimson bare cheek-patches and gape thighs bare and blue/grey. But all is clearly not well, and we hope this ‘warning shot across the bow’ enables conservation actions to save the species while there are still sufficient birds left for this to be possible.”Īs of November 2021, the palm cockatoo has been added to the endangered list by the Queensland Government.Related publications: Probosciger aterrimusįour: P.a. “It’s too easy to just assume that all is well in the remote north of Australia. “We hope this analysis shows that we cannot take the apparent continuing presence of palm cockatoos for granted. Fire regimes have changed since Europeans started managing the landscape and are much ‘hotter’ and more destructive these days.” “Palm cockatoo habitat is being badly affected by large fires that burn the woodland and destroy nest hollows each dry season. Less than ideal land management is also taking its toll. “Over 5000 square kilometres of bush are ear-marked for clearing for bauxite mining in the next 20 years making it essential that mining companies find improved ways to identify and preserve palm cockatoo habitat.” On the west coast, he says a lot of palm cockatoo habitat is being lost to broad-scale habitat clearing for bauxite mining. “We worked out that the other populations are not doing well enough to support Kutini-Payamu National Park (east) – in fact the opposite occurs and Kutini-Payamu is a ‘sink’ that causes the other two populations to also decline,” Rob says. Using data from a long-term monitoring project and new information about breeding biology, the researchers examined exactly how connected these three individual populations of palm cockatoo are, and found that good breeders in one population were not compensating for the lower reproduction rates of another population. There’s one within the Iron and McIlwraith Ranges on the eastern side of Cape York, a population within the inter-connected patches of rainforest on the western side of the Great Dividing Range, and a population within the forest patches closer to the tip of Cape York. There are three existing populations of palm cockatoo in Australia, all within the Cape York Peninsula. This slow reproduction rate, paired with the threat of habitat destruction, has set the palm cockatoo on a dangerous trajectory. ![]() Palm cockatoos produce one successful offspring every 10 years. Emu - Austral Ornithology The gradual loss and episodic creation of Palm Cockatoo (Probosciger aterrimus) nest-trees in a fire- and cyclone-prone habitat The. Related: Male palm cockatoos are using drums to seduce femalesĪccording to the research, populations of palm cockatoo, of which only an estimated 2000 are left in the wild, are projected to be half the size in 50 years. ![]()
