Population justification: The population is estimated to number 1,000-10,000 individuals by McGowan and Garson (1995). It is placed in the band 2,500-9,999 mature individuals here, equating to 3,750-14,999 individuals, rounded here to 3,500-15,000 individuals.
Trend justification: The species is suspected to be undergoing a rapid population decline owing to the loss and fragmentation of its forest habitat, although it is mainly restricted to relatively less threatened hill forest, with the possibility that the rate of decline is slower than this (B. van Balen in litt. 2012), necessitating further research.
