Population justification: The global population is preliminarily estimated to number 10,000-50,000 mature individuals, pending further research. This is roughly equivalent to 15,000-75,000 individuals in total.
Trend justification: A moderately rapid and on-going population decline is suspected on the basis of rates of habitat loss and degradation.
