||30 cm. Medium-small, forest-dwelling owl. Light rusty facial disk. Rusty upperparts speckled black, rusty-cream underparts spotted black, wings barred black and rufous. Finely barred tail. Nuchal area and bend of wing darker than rest of plumage. Black iris. Similar spp. Sulawesi Owl T. rosenbergi is much larger, with dusky facial disc and upperparts finely spotted white. There are two morphs of this species, of which the darker is most difficult to differentiate from T. rosenbergi. Voice Single nasal, hoarse, hissing shriek lasting about 1.8 seconds and delivered infrequently every 5-7 minutes (Mauro and Drijvers 2000).

Given the continuing habitat destruction and degradation taking place in its range, the apparently small population of this elusive owl is likely to be declining and fragmented. As a result, it qualifies as Vulnerable.
|Previously published Red List assessments:|
- 2012 – Vulnerable (VU)
- 2008 – Vulnerable (VU)
- 2004 – Vulnerable (VU)
- 2000 – Vulnerable (VU)
- 1996 – Data Deficient (DD)
- 1994 – Data Deficient (DD)
- 1988 – Threatened (T)
|Population:||The population is estimated to number 2,500-9,999 mature individuals based on an assessment of known records, descriptions of abundance and range size. This is consistent with recorded population density estimates for congeners or close relatives with a similar body size; its description as being uncommon or rare, and the fact that only a proportion of the estimated Extent of Occurrence is likely to be occupied. This estimate is equivalent to 3,750-14,999 individuals in total, rounded here to 3,500-15,000 individuals.|
Trend Justification: Forest loss below 1,000 m on the Minahas peninsula has been near total and continues in other parts of the species's range. As a result it is suspected to be declining at a moderate rate.
