Togian Boobook Ninox burhani

A medium-sized brown owl with piercing yellow eyes, confined to the Togian Islands. Cryptically patterned, with a mottled breast, an unmarked pale lower belly, indistinct white eyebrows, and widely scattered white markings on wings. Pairs inhabit forests of lowlands and hills, also occurring in slightly modified habitats. Migrant Northern Boobook visits these islands too; Togian Boobook differs in its finer markings below, pale belly, widespread white markings on wings, and understated white eyebrows. Frog-like vocalizations are unlike those of any owl in region: a grating, but explosive “grrrrr-wow-waow.”
