Enggano Scops-owl Otus enganensis

Justification
This species has a small population occupying a very small range, but its habitat is apparently still intact and the population is probably stable. As a result the species is considered Near Threatened. The possibility of agricultural expansion in the future is a real threat and requires careful monitoring.

Taxonomic note
Otus magicus and O. tempestatis (del Hoyo and Collar 2014) were previously lumped as O. magicus, and O. alfredi, O. siaoensis, O. enganensis, O. insularis and O. beccarii (del Hoyo and Collar 2014) were split from O. magicus following Widodo et al. (1999), Lambert and Rasmussen (1998), Andrew (1992) and Holt et al. (1999). Prior to that all these taxa were lumped in O. magicus following Sibley and Monroe (1990, 1993).

Distribution and population
Otus enganensis is endemic to Enggano Island, off south-west Sumatra, Indonesia (BirdLife International 2001). Reports as to its status differ, from very rare to quite uncommon.

Population justification
With a range of not more than 200 km2, the population is very unlikely to exceed the band 2,500-9,999 mature individuals and may fall some way below this. This estimate equates to 3,750-14,999 individuals in total, rounded here to 3,500-15,000 individuals. This preliminary estimate requires clarification.

Trend justification
The population is suspected to be stable in the absence of evidence for any current declines or substantial and immediate threats.

Ecology
It is thought to occupy forest and wooded areas, and apparently feeds mainly on insects, spiders and other arthropods (König and Weick 2008).

Threats
Habitat destruction on Enggano has, thus far, been minimal, but recent tentative proposals for agricultural development suggest the possibility for future radical change, and this may exert pressure on the small population of this species.

Conservation Actions Underway
CITES Appendix II. Conservation Actions Proposed
Revisit Enggano Island to assess the species's status and determine whether habitat conversion has occurred. Conduct awareness programmes to discourage hunting. As a precaution, protect significant areas of suitable forest, in both strictly protected areas and community-led multiple use areas.
