The Siau Scops Owl, Otus siaoensis is a critically endangered owl and may be extinct. They live on the island of Siau, 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 population (which was small to begin with because of limited range) is being devastated by loss of habit due to excessive logging of the forest on the island and there would be very few if any individuals left.
