Population justification: The global population size has not been quantified, but this species is described as 'uncommon and patchily distributed' (Stotz et al. 1996).
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).
