The mottled wood owl is a species of large owl found in India and Nepal. They are found in gardens and thin deciduous forests adjacent to dry thorn forests or farmland. They are easily detected by their distinctive tremulous, eerie calls at dawn and dusk. The characteristic call is a duet of the male and female, while other notes include a low hoot and a screech. Their large size, lack of "ear" tufts and the concentric barring on the face make them easy to identify.

Owls are birds from the order Strigiformes, which includes over 200 species of mostly solitary and nocturnal birds of prey typified by an upright stance, a large, broad head, binocular vision, binaural hearing, sharp talons, and feathers adapted for silent flight. Exceptions include the diurnal northern hawk-owl and the gregarious burrowing owl.
