Population justification: The population is estimated to be small, as the species is only known from c. 180 km2 of habitat. It is placed in the band 1,000-2,499 mature individuals, equating to 1,500-3,749 individuals in total, rounded here to 1,500-4,000 individuals.

Trend justification: This species is suspected to be undergoing a slow to moderate decline, owing to continuing habitat degradation within its range. Tree cover within the range has been lost at a rate of c. 8% over the past ten years (Global Forest Watch 2020). Apart from woodland, the species is also found in open shrub and may tolerate a low level of habitat degradation (Schuchmann et al. 2020); therefore, population declines are potentially lower than the rate of tree cover loss. Overall, the rate of population decline is unlikely to exceed 10% over ten years.
