Scops owls are typical owls in family Strigidae belonging to the genus Otus and are restricted to the Old World. Otus is the largest genus of owls with 59 species. Scops owls are colored in various brownish hues, sometimes with a lighter underside and/or face, which helps to camouflage them against the bark of trees. Some are polymorphic, occurring in a greyish- and a reddish-brown morph. They are small and agile, with both sexes being compact in size and shape. Female scops owls are usually larger than males.
