Justification of Red List category
This recently-split hawk-owl is known with certainty from just two islands, on which habitat loss and degradation have been extensive, owing to a variety of threats including clearance for agriculture and grazing, gold mining and logging. The total population is likely to be very small, with both sub-populations containing fewer than 250 mature individuals and in continuing decline. It is therefore listed as Endangered.

Population size: 250-999

Population trend: Decreasing

Extent of occurrence (breeding/resident): 3,500 km2

Country endemic: Yes
