Justification of Red List category
As a result of decades of population decline, Indian Skimmer is listed as Endangered as it now has a small global population size and is suffering a continuing decline in excess of 20% in 11 years (two generations). Increased variation in water levels along the rivers on which it breeds due to dams, irrigation and sand mining leads to both flooding of colonies and low water levels that allow access to terrestrial predators and people onto breeding islands. Both situations result in high egg and chick mortality, and the rate of reproduction does not appear to be sufficient to maintain the population. Declines have been continuing for many decades in this previously common and distinctive bird. The species has been lost as a breeding bird from all of South East Asia, Myanmar and probably now also Pakistan. The recent and future rate of population reduction is thus estimated at 34-46% over three generations.
