Justification of Red List category
This recently-split hawk-owl is known from just six small islands, on which habitat loss and degradation have been extensive, owing to a variety of threats including clearance for agriculture, orchards and grazing livestock. The total population is likely to be very small, with all subpopulations containing fewer than 1,000 mature individuals and in continuing decline. It is therefore listed as Vulnerable.

Population size: 1000-2499

Population trend: Decreasing

Extent of occurrence (breeding/resident): 9,100 km2

Country endemic: Yes
