Population justification: This species's global population is preliminarily estimated at 10,000-100,000 mature individuals on the basis that it may not exceed a five-figure total. This estimate equates to 15,000-150,000 individuals in total.
Trend justification: A moderately rapid and on-going population decline is suspected on the basis of rates of habitat degradation and levels of pollution and over-fishing.
