Population justification: The global population size has not been quantified, but the species is described as fairly common but rather local (del Hoyo et al. 2006). The population is suspected to be in decline owing to ongoing habitat loss and degradation (del Hoyo et al. 2006).
Trend justification: The population is suspected to be in decline owing to ongoing habitat loss and degradation (del Hoyo et al. 2006).
