Sulu Boobook Ninox reyi

A fairly small owl of forest on the Sulu Islands. Uniformly barred, with brown upperparts and head, orange-brown underparts, white speckling on the wing, a broken pale bar behind the shoulder, a pale belly, long whiskers around the face, and yellow eyes. Note the white throat patch. Probably the only owl in its range except for Mantanani Scops-Owl, but Sulu Boobook is rufous rather than gray and lacks the black line around the face. Voice includes strange clucking notes starting with a rapid series ending in three slower notes: “kukukukukuku klok-klok-klok.”
