Population justification: Tobias and Seddon (2002) provided estimates of the species's population size using five methods, the most reliable of which yielded an estimate of 115,000 individuals. The other methods gave estimates ranging from 98,000-152,000 individuals, and these figures are taken as the species's population range. This is likely equivalent to 65,000-110,000 mature individuals.

Trend justification: This species is inferred to be declining owing to continuing habitat loss (Global Forest Watch, 2021), the likely rate of which is placed in the band of 30-49%.
