Population justification: The global population size has been estimated at substantially more than 10,000 mature individuals (J. Ko in litt. 2014), thus it is placed in the band for 20,000-49,999 mature individuals, which is assumed to equate to c.30,000-75,000 individuals.

Trend justification: There are no data on population trends; however, habitat loss is suspected to be causing a slow to moderate decline in this species's population.
