Population justification: The population was previously estimated to number 2,500-9,999 individuals, based on an assessment of known records, descriptions of abundance and range size. However, the species has since been found at additional locations, extending its known range and suggesting that the population estimate should be revised upwards. As a result the population is now placed in the band for 10,000-19,999 individuals, roughly equivalent to 6,600-13,400 mature individuals.

Trend justification: The population status of this species is very poorly known. It is suspected to be stable on the basis that it favours secondary habitats and that human activities are resulting in both the creation and destruction of such habitats, and thus an on-going turn-over in suitable areas with, however, no discernible net change in recent years (R. J. Timmins in litt. 2013). The area of suitable habitat in Laos may in fact be increasing, at least temporarily (S. Mahood in litt. 2012, J. W. Duckworth in litt. 2013), but further investigation is needed.
