Population justification: The global population size has not been quantified, but the species is described as abundant on the Nyika plateau and scarce elsewhere in its range (del Hoyo et al. 2005).

Trend justification: The population is suspected to be in decline owing to ongoing habitat destruction and fragmentation.
