Population justification: The species is generally rare; its population is placed in the band 2,500-9,999 mature individuals, equating to 3,750-14,999 individuals, rounded here to 3,500-15,000 individuals.

Trend justification: A rapid and on-going population decline is suspected on the basis of continuing habitat destruction and fragmentation.
