Population justification: The population is estimated at c.6,850 total individuals (Dinesen et al. 2001), placed here in the 2,500-9,999 band. The number of mature individuals therefore is roughly estimated to be 4,520, also placed here in the 2,500-9,999 band.

Trend justification: Between 2000-2019, 8.2% of forest was lost within the species's range (Global Forest Watch 2020). As the species has a high forest dependency, the population is inferred to be in decline owing to the clearance and degradation of forests both within and outside protected areas (Dinesen et al. 2001; L. Dinesen in litt. 2007).
