Population justification: The population size of this species has not been quantified, but the speces is described as local and uncommon. Tentatively, the population is suspected to number 2,500-9,999 mature individuals, but this requires confirmation.
The subpopulation structure has not been investigated, but based on continuous observational records within the range (per eBird 2020), it is assumed that all individuals belong to the same subpopulation.

Trend justification: Data on population trends are lacking, but declines are suspected owing to habitat loss. Tree cover within the range has been lost at a rate of 3% over the last ten years (Global Forest Watch 2020), but even though the species is able to tolerate some habitat disturbance the rate of population decline may be higher due to the additional impacts of degradation of forests and arid scrub. Tentatively, the rate of decline is here placed in the band 1-9% over ten years.
