The white-fronted scops owl (Otus sagittatus) is a small Asian owl in the family Strigidae. It has a declining population about which little is known, and is dependent on lowland and foothill forests which are rapidly being destroyed. This species of owl is considered vulnerable and has a population of about 2,500–10,000. It is found in west of Thailand and also in peninsular Malaysia. [1] Its range covers 149,000 km2 (58,000 sq mi) of forest at altitudes of 0–700 m (0–2,300 ft) above sea-level.
The white-fronted scops owl was described by the American ornithologist John Cassin in 1849 and given the binomial name Ephialtes sagittatus. [3] [4] The species is monotypic. [5]
This kind of owl has two modes of defense. The first is that it can puff up its feathers to triple its body size. The second is that it can stretch its body upwards and turn its head at an angle in the direction of the predator that it is hiding from, reducing visibility.
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.

It is a nocturnal owl that feeds at night and has a nesting season from February to April.
