Siau Scops-Owl Otus siaoensis

An extremely rare, little-known small brown owl confined to the tiny island of Siau. Cryptically patterned with ear tufts and yellow eyes. Currently only known from a 19th-century specimen, it has not been seen in the wild in modern times, and there are no confirmed field photographs or sound recordings. Presumably a very low-density forest owl, as very little habitat remains on Siau. Should be unmistakable, as it is the only owl on the island. Call currently unconfirmed, although recently a rolling "ook-grrrrah” has been reported.
