Timor boobook Ninox fusca

Brown owl with bright yellow eyes, densely-marked pale underparts, and white-spotted wings. Found only on Timor, where, aside from the very different Barn Owl, it is the only owl; migratory Northern Boobook could turn up on Timor, but has an entirely dark brown back. Inhabits wooded areas in the lowlands and foothills of the island. Gives a somewhat slurred, bouncy-sounding “woop-woop!”, as well as a smoother, deeper “dwoop-a-woop!”. Formerly regarded as a subspecies of Southern Boobook.
