Population justification: The population size has not been estimated here, but the species has been described as locally common (Hume and Kirwan 2017).

Trend justification: Precipitous declines have occurred in parts of South-East Asia, but trends in India, which now probably holds the bulk of the population, are less clear, making analysis of past population trends difficult. Nevertheless, the species is expected to undergo a moderately rapid reduction over the next three generations, as threats, such as dam construction and disturbance, increase in prevalence.
