Justification of Red List category
This species is believed to have undergone a rapid decline in the last three generations (44 years) in Australia, and declines of a similar magnitude elsewhere in its range are possible, with local extirpations reported from parts of New Guinea. It is therefore classified as Vulnerable. However, the decline in Australia resulted from an extraordinary rate of habitat destruction which has virtually ceased. Further information from New Guinea may indicate that the species would be better listed as Near Threatened if hunting and high-impact industrial logging does not increase in the large areas of existing habitat there.
6000-15000 mature individuals
Distribution size (breeding/resident):
Land-mass type - shelf island - Continental islands include all other islands or island groups. Generally they were once part of continents and lie on a continental shelf of < 200 m sea depth.
Land-mass type - Australia - Australia is classified as an Island-Continent.
Land-mass type - oceanic island - Oceanic islands are islands or island groups that are <200,000 sq km in size and separated from other land masses by >200 m sea depth. Generally Oceanic islands are islands or island groups that are <200,000 sq km in size and separated from other land masses by >200 m sea depth. Generally they have never been connected to a continental area by a land-ridge, and are volcanic in origin.
