Population justification: The global population size has not been quantified, but the species is reported to be generally fairly common (Pratt et al. 1987, Flegg and Madge 1995, Coates 1990).

Trend justification: This population is suspected to be in decline owing to habitat destruction (del Hoyo et al. 2005).
