Population justification: Garnett et al. (2011) estimate that the current population probably contains around 2,000 mature individuals and is declining. It is placed in the band 1,000-2,499 mature individuals. This equates to 1,500-3,749 individuals in total, rounded here to 1,500-4,000 individuals.
Trend justification: This species's population is suspected to be decreasing in line with habitat loss and degradation, which has also caused range contractions. The likely rate of decline, however, has not been estimated.
