Population justification: The species is at least locally common, with a population of perhaps 1,000 individuals at one site with c.20 km2 of suitable habitat in East Timor (C. Trainor in litt. 2007). On Wetar, densities of 5-15 birds/ha have been recorded in gallery forest in Naumatang gorge at 100-200 m, and the island appears to support a very high proportion of the global population. Overall, the total population has been crudely estimated at perhaps 10,000-20,000 birds, thus it is placed in the band 10,000-19,999 individuals. This equates to 6,667-13,333 mature individuals, rounded here to 6,000-15,000 mature individuals.
Trend justification: A moderate and on-going decline in this species's population size is suspected owing to hunting and continuing forest loss.
