Population justification: The population is estimated to number fewer than 10,000 individuals because the species probably exists at relatively low densities across its range. It 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: The population is suspected to be in decline owing to changes in land use across much of the species's range, however the magnitude of this decline is unclear.
