Justification of Red List category
This owl has a very small, rapidly declining population due to widespread loss of riverine forest, increasing development along rivers and dam construction. It therefore qualifies as Endangered. However, recent information suggests the population size may be greater than previously thought. If this is confirmed, the species may warrant downlisting to Vulnerable.
