Population justification: The global population size has not been quantified, but the species is reported to be scarce in peninsular Malaysia and abundant elsewhere (del Hoyo et al. 1999). The population is suspected to be in decline owing to over harvesting of eggs and nestlings (del Hoyo et al. 1999).

Trend justification: The population is suspected to be in decline owing to over harvesting of eggs and nestlings (del Hoyo et al. 1999).
