 in 1998.

The IUCN classifies it as Endangered (B1ab(i, ii,iii, v)). This means that based on currently available data, it is estimated to occur in no more than five locations over a total area of less than 5000 km², with both habitat quality and availability, and numbers declining, and some of the subpopulations in danger of disappearance. Due to its shyness and the call which might be mistaken for that of a Rufous-banded Owl, it could be more widespread than presently known, although surveys at several seemingly appropriate localties have failed to find any evidence of it.
