Population justification: The population is suspected to fall in the band 2,500-9,999 mature individuals, based on the suitable area of habitat remaining on Tablas and reported density estimates of congeneric species.

Trend justification: The population is suspected to declining at a slow rate due to ongoing habitat conversion.
