The Brown hawk-owl (Ninox scutulata), also known as the brown boobook or oriental boobook, is a medium-sized owl found in much of southern Asia and Indonesia.

Description

Brown hawk-owls are about 13 inches in length, with a wingspan of up to 19 inches. The upper plumage is a dark brown, with ochre-colored bands streaking the primaries and secondaries of the wings. The underside is whitish in color, bearing brown streaking throughout. The legs are feathered to the toes.

It is called a "hawk-owl" due to similarities in shape and appearance to hawks; like other members of the genus Ninox it lacks a facial disk, yet still retains the distinctive owl-like eyes, which are yellow in color.

Feeding

Brown hawk-owls subsist on large insects such as beetles and grasshoppers, but will also take frogs, lizards, small birds and rodents, and occasionally small bats.
