Genus

Members of the genus Otus are the Scops and Screech owls. They are relatively small owls, with short, rounded wings. Most have erectile ear-tufts. Otus is a worldwide genus, containing some 45 species.

Physical charateristics

Small, rufous-brown, forest-dwelling owl. Rusty-brown facial disc, with prominent white eyebrows extending into ear-tufts. Rufous-brown upperparts, often with buffy or whitish (and distinctly black-tipped) collar and whitish scapular stripe. Whitish or creamy underparts. Golden-yellow iris. Similar spp. Sunda Scops-owl O. lempiji is slightly larger with generally greyer facial disc, buffy eyebrows, brown or orange iris and different call. Voice Usually silent, but gives explosive poo-poo in alarm and (especially young birds) prolonged hissing contact note. Hints Possibly most easily found by listening for hissing or wailing of fledglings

Range

Oriental Region : West Java

Habitat

It inhabits tropical upper montane forest between 1000 m and 2000 m

Reproduction

No data

Feeding habits

Primarily insects like beetles, grasshoppers and, its favorite, mantids. Sometimes small lizards or snakes are taken. Hunts catching prey on trunks or foliage, also on ground.

Conservation

This small owl qualifies for Vulnerable because its small range is undergoing contraction and increasing fragmentation through habitat loss, a factor that implies reductions in its small population. However, its silent, nocturnal habits and unobtrusive behaviour may have resulted in it being consistently under-recorded. Additional locality records and population data may require a reassessment of its threat status.
Otus angelinae is endemic to the island of Java, Indonesia, where it is known from seven mountains, though there are recent records from only three. An evaluation of records and museum/zoo specimens, coupled with its reputed silence, suggests it may be more numerous and widespread than available evidence shows
Javan Scops Owl status Vulnerable
