Population justification: The global population size has not been quantified, but the species is reported to be widespread in suitable habitat and elsewhere patchily distributed and uncommon (del Hoyo et al. 2001).

Trend justification: The population is suspected to be in decline locally owing to ongoing destruction of natural forest habitat (del Hoyo et al. 2001).
