Population justification: Hadden (2002) estimated the population to number over 10,000 individuals and to be common, thriving and encountered everywhere. It is placed in the band 10,000-19,999 individuals here, equating to 6,667-13,333 mature individuals, rounded here to 6,000-15,000 mature individuals.
Trend justification: There are no data on population trends; however, habitat degradation and re-settlement of previously occupied areas on Bougainville is suspected to be causing a decline, although the likely rate of decline has not been estimated.
