This small owl qualifies for Vulnerable because its small range is undergoing contraction and increasing fragmentation through habitat loss, a factor that implies reductions in its small population. However, its silent, nocturnal habits and unobtrusive behaviour may have resulted in it being consistently under-recorded. Additional locality records and population data may require a reassessment of its threat status.

Rufous-brown upperparts, often with buffy or whitish (and distinctly black-tipped) collar and whitish scapular stripe. Whitish or creamy underparts. Golden-yellow iris. Similar spp. Sunda Scops-owl O. lempiji is slightly larger with generally greyer facial disc, buffy eyebrows, brown or orange iris and different call.
