Siau Scops-Owl

Otus siaoensis (Schlegel, H 1873)

The Siau scops owl is a critically endangered owl species, which may even be extinct. 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. 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. Source: Wikipedia
