Population justification: An increase in ornithological surveys within Cambodia has revealed that extensive areas of suitable habitat appear to support this species at relatively high densities. Hence its population estimate has been revised upwards considerably and is probably best placed within the band 20,000-50,000 individuals.

Trend justification: The species is thought to be decreasing owing to habitat encroachment and the ongoing loss of forest, particularly in Cambodia. However, it is unlikely to be adversely affected by selective logging, and large parts of its range will avoid exploitation in the near future owing to areas of uncleared landmines.
