Population justification: The global population size has not been quantified, but the species is reported to be fairly common (del Hoyo et al. 1997).

Trend justification: This species's population is suspected to be undergoing a moderately rapid decline owing primarily to continued trapping pressure for the cagebird trade, but also the felling of nest trees, as supported by evidence of local extinctions and declines in some parts of its range.
