The Siau Scops Owl is a small owl recorded on Siau Island. Its brown plumage has dark streaks and a rufous-buff collar, and its eyes are yellow. Its current presence has not been confirmed.
The head and upperparts are dark brown and black-streaked, with a rufous-buff mantle and collar. The tail is barred, the eyes are yellow, and the bill is horn-yellow.
A 2010 guide gives humid forest as the habitat. BirdLife’s 2001 account describes the species as presumed to have been a forest-dweller; the only known specimen was collected in 1866, and later calls or local reports were not confirmed.
An extinction-risk assessment has not been added yet.
