Population justification: Its status and population size are very poorly known, owing to its apparent scarcity, the species's restricted range and identification difficulties. Its total population may include c.2,500-5,000 mature individuals (K. Sivakumar in litt. 2012). This equates to c.3,700-7,500 individuals, assuming that mature individuals account for around 2/3 of the total population.
Trend justification: A moderate and on-going population decline is suspected on the basis of rates of habitat loss, but this requires further documentation.
