Population justification: The global population size has not been quantified. Anecdotal accounts suggest it is not as rare as previously thought in north-west Vietnam, it may be rather common on the Da Lat Plateau, and it is not uncommon in good forest on Hainan. Its status on the Kon Tum Plateau is uncertain (del Hoyo et al. 2008).

Trend justification: A slow and on-going population decline is suspected owing to on-going forest loss throughout the species's range. The magnitude of these declines may be relatively slight as this species is tolerant of logged forests.
