Population justification: The global population size has not been quantified, but the species is reported to be generally scarce but locally fairly common (Coates 1990, Flegg and Madge 1995).

Trend justification: This population is suspected to be in decline owing to ongoing habitat loss and degradation (del Hoyo et al. 2007).
