Justification of Red List category
This species was until recently classified as Data Deficient, because it was known from very few records and there was insufficient evidence to estimate the current range size or the population size and trend. By now, knowledge about the species's distribution and population size has increased: the largest subpopulation, on Great Nicobar, is likely to be close to or exceed 1,000 mature individuals, the species also occurs on Nancowry Island and perhaps on other islands of the southern Nicobar group. However, there remains considerable uncertainty over the rough population estimate due to a lack of information over the degree to which the species is habitat restricted. The species is therefore listed as Near Threatened, as it has a small population size which is suspected to be undergoing a continuing decline due to habitat clearance and degradation.
