Population justification: This species appears to exist at very low densities, prompting Ferguson-Lees and Christie (2001) to infer that the total population is unlikely to exceed the uppermost hundreds; however, this seems very conservative given its extensive range. Pending further research, the population is placed in the band 2,500-9,999 mature individuals. This equates to 3,750-14,999 individuals in total, rounded here to 3,500-15,000 individuals.
Trend justification: This species's population is suspected to be undergoing a moderately rapid decline owing to continued habitat loss.
