Population justification: The global population size has not been quantified, but the species is described as locally common (del Hoyo et al. 2006).
Trend justification: The population is inferred to be in decline owing to on-going habitat loss and degradation (del Hoyo et al. 2006), and it is suspected that it will undergo a moderately rapid decline over the next three generations owing to expected increases in the expansion of oil-palm cultivation in its range (F. Dowsett-Lemaire in litt. 2013).
