Population justification: The global population size has not been quantified, but the species is reported to be generally uncommon (Flegg and Madge 1995). This population is suspected to be in decline owing to ongoing habitat destruction (del Hoyo et al. 2007).

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