This inconspicuous and extremely poorly known forest owl is listed as Vulnerable because, although it is suspected to have a very small population of less than 1,000 mature individuals, it appears to tolerate substantial habitat degradation and is therefore no longer inferred to be undergoing continuing declines.

|Range Description:||This species is endemic to the Sula Islands, Maluku, Indonesia, where it is known from just one specimen (collected in 1938) and a handful of subsequent sight records, all from the largest island in the group, Taliabu (Davidson et al. 1991, Rheindt 2010). However, it appears to be well-known to villagers at Binadesa and recent records suggest it can occupy secondary growth and bamboo thickets in the vicinity of habitation. Evidence also suggests that it may occur within a broad elevational range (Rheindt 2010, C. Robson in litt. 2013). It is possible that future surveys will reveal its presence on the neighbouring island of Mangole and perhaps Sanana (Rheindt 2010). There is no information on its population size, but the paucity of records (even taking into account its inconspicuous nature and the fact that it could easily be overlooked) indicate that it could still be very scarce.|
