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. macgillivrayi: Both adults as in aterrimus but larger in size. 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. Birds forage for seeds, nuts, fruits, berries and leaf buds.Related publications: Probosciger aterrimusįour: P.a. It is seen in pairs and small groups, and is conspicuous in its behaviour. Disruption of the rainforest/woodland balance due to mismanagement (which can reduce availability of nest hollows)Įcology: The Palm Cockatoo is found in New Guinea and adjacent islands, and N Australia (Queensland) in lowland areas, rainforest, forest edge, monsoon woodland, and tall secondary growth, at elevations up to 1350m (4428 ft).The main cause was fire, caused by people. Between 19, roughly 26% of all Palm Cockatoo nest trees were taken out of circulation in Iron Range National Park, Cape York. However, the population is suspected to be in decline due to ongoing habitat degradation and destruction, and unsustainable levels of trapping. In Australia, subspecies macgillivrayi is restricted to the northern Cape York Peninsula and in New Guinea, it is widespread, mostly in the lowlands and foothills but occasionally ranging up to 1,350 m. History: The Palm Cockatoo (Probosciger aterrimus) is found in Australia and New Guinea. 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. Wild population: Unknown and declining, but subspecies macgillivrayi is believed to have a stable population of about 3000 individuals. IUCN/CITES Status: Least Concern / Appendix I With your help we can complete these important tasks to better understand the species, and continue to deliver effective solutions to further their conservation. WPT also began The Palm Cockatoo Fund, in mid-2001, to collect monies to further conservation and research of the species.įocus of future work: Currently WPT is supporting the work of the Palm Cockatoo Project being led by Christina Zdenek, partly funding important conservation-related research which includes a photo identification study begun in 2010. Significant findings were that the Palm Cockatoo is a highly specialized feeder that has a low breeding frequency. Progress and outcomes: Beginning in 1999 WPT has supported Steve Murphy's Ph.D research and conservation for the Palm Cockatoo through the last decade, funding monitoring and tracking, observing nest sites, studying breeding habits and conducting surveys. Habitat alteration and nest tree loss threatens speciesĪbout one-quarter of all Palm Cockatoo (Probosciger aterrimus) nest trees have been removed in Iron Range National Park, Cape York.
