Enggano Scops-Owl Otus enganensis

Small rufous-brown scops-owl with bright yellow eyes and a whitish “X” on the face. Endemic to the island of Enggano, where it is the only resident scops-owl; migrating Oriental Scops-Owl may stop over on the island, but are readily distinguished by their larger size, more well-defined facial disc, and lack of prominent white facial markings. Inhabits forest and forest edge. Gives a series of deep, throaty, and somewhat frog-like “ghwerr”s.
