Population justification: The population is estimated at under 100,000 individuals (S. Garnett in litt. 2003). Population loss in southern Australia occurred prior to the past three generation (35 years) period, and the population in the north of the country is now relatively stable. Trends in Indonesian and Papua New Guinea are unknown but birds here account for only a fraction of the global population, but combined with local declines in some parts of Australia due to invasive non-native mammals, pesticide use and hunting (Garnett and Crowley 2000, Ziembicki and Woinarski 2007, Collar and Garcia 2020), the species' population size is suspected to be slowly declining.
Trend justification: Population loss in southern Australia occurred prior to the past three generation (47 year) period, and the population in the north of the country is now relatively stable. Trends in Indonesian and Papua New Guinea are unknown but birds here account for only a fraction of the global population. The overall population trend is therefore suspected to be stable.
