Population justification: The global population size has not been quantified, but this species is described as 'uncommon and patchily distributed' (Stotz et al. 1996). The population is suspected to be in decline owing to habitat loss and degradation caused by over-grazing and excessive burning (Ridgely and Tudor 1989).

Trend justification: The population is suspected to be in decline owing to habitat loss and degradation caused by over-grazing and excessive burning (Ridgely and Tudor 1989).
