A small, richly rufous-colored owl confined to the island of Sulawesi. Largely chestnut-colored, with white markings on the wings and an entirely rufous head with yellow eyes. Mottled underneath, with a white belly in the southern part of its small range. Inhabits treetops of montane forest, typically in pairs. Lacks the white facial markings of the similar Ochre-bellied Boobook; also occurs at higher elevations and sounds markedly different. Gives a distinctive two-part staccato knocking call, “crock-crock,” often repeated.
