Population justification: The population size is preliminarily estimated to fall into the band 10,000-19,999 mature individuals. This equates to 15,000-29,999 individuals in total, rounded here to 15,000-30,000 individuals.

Trend justification: A rapid and on-going population decline is suspected, in line with rates of habitat loss.
