Population justification: The global population size has not been quantified, but the species is reported to be widespread and locally common (del Hoyo et al. 2001). The population is suspected to be in decline owing to destruction of large trees which provide nesting sites (del Hoyo et al. 2001).

Trend justification: The population is suspected to be in decline owing to destruction of large trees which provide nesting sites (del Hoyo et al. 2001).
