Population justification: The species is described as 'uncommon' (Stotz et al. 1996). Based on its localised distribution, the population is suspected to number 2,500-9,999 mature individuals, though this requires confirmation.
Even though the subpopulation structure has not been assessed, it is here assumed that the species forms several isolated subpopulations with likely less than 1,000 mature individuals each.

Trend justification: The species is suspected to be declining, as habitat is lost and degraded through agricultural activities and burning, which is moreover hampering vegetation recovery (Remsen 2020). The rate of decline has not been quantified, but is likely low.
