Justification of Red List category
This hornbill has been downlisted to Vulnerable because the total population size is estimated to be larger than previously believed, although remains very small. It may have increased since 2000, or previous estimates may have been too low. The population is currently believed to be stable, though there are plausible future threats from introduced mammals, the potential introduction of disease or natural disasters, as Narcondam Hornbill remains restricted to one tiny island. As such it is assessed as Vulnerable under Criterion D1 + 2. 



Population size: 300-650
