One of the three Mascarene owls, it was formerly classified in the genus Mascarenotus, and most likely was similar to a long-eared owl in size and appearance, but with nearly naked legs. However, according to recent studies, it and its relatives belong to the genus Otus, and is likely descended from the Otus sunia lineage.
The Siau scops owl is a critically endangered owl species. They live on Siau Island, north of Sulawesi, Indonesia and are (were) forest dwellers. The species is only known from a single holotype from 1866 although there have been some local reports in recent years.

The taxonomic arrangement for this owl has not been fully worked out. While recognized as a distinct species by the IOC, others consider it as a subspecies of either the Sulawesi scops owl or Moluccan scops owl.
