Population justification: The global population size has not been quantified, but the species is described as locally fairly common throughout its small range (del Hoyo et al. 2003).

Trend justification: This species's habitats are under pressure from logging; however, selective logging may increase local densities (del Hoyo et al. 2003), thus an overall trend is difficult to determine.
