Population justification: The population size is preliminarily estimated to fall into 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: A rapid and on-going population decline is suspected on the basis of rates of habitat loss.
