Siau scops owl

The Siau scops owl (Otus siaoensis) 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 more recent potential sightings, including one in 2017. Even so, their habitat is being lost to excessive logging of the forest on the island and there would be very few if any individuals left. 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.

On December 14, 2017, a video of a purported Siau Scops-Owl trapped in a building was uploaded to YouTube (see external links). Although it has been the subject of debate, the scientific community has not been able to confirm the bird's identification.
