Justification of Red List category
This species has been uplisted to Vulnerable on the basis that increasing human disturbance, dam construction, waterbody management, and predation are causing a rapid population decline. Whilst the situation is more concerning in Southeast Asia despite its marginal occurrence here, localised declines also continue to occur across India, of which currently holds the majority of the population. Comprehensive monitoring is however required to limit uncertainty in population trends.
