Population justification: The population is preliminarily estimated to number 1,000-2,499 mature individuals, equating to 1,500-3,749 individuals in total, rounded here to 1,500-4,000 individuals. This requires confirmation.

Trend justification: A rapid and on-going population decline is suspected on the basis of rates of habitat loss.
