Сплюшка лусонська Otus longicornis

A fairly small owl of lower-elevation montane forest on Luzon. Dark brown on the head, chest, and upperparts, with barred flight feathers. Eyebrows, beard, and belly whitish, with some patterning. Overlaps geographically with Philippine Scops-Owl, but Luzon is smaller, usually found at higher elevation, and has yellow rather than orange-brown eyes. Voice includes a single slightly rising then falling whistled note, repeated at intervals.
