Simeulue Scops-owl Otus umbra

Justification
This species is listed as Near Threatened because, although it is very poorly known, there are some indications that its very small range supports a moderately small, fragmented population, which may be undergoing a continuing decline owing to forest degradation. Further information may indicate it is more threatened.

Taxonomic source(s)
del Hoyo, J.; Collar, N. J.; Christie, D. A.; Elliott, A.; Fishpool, L. D. C. 2014. HBW and BirdLife International Illustrated Checklist of the Birds of the World. Barcelona, Spain and Cambridge UK: Lynx Edicions and BirdLife International.

Distribution and population
Otus umbra is endemic to Simeulue Island, off north-west Sumatra, Indonesia (BirdLife International 2001). Reports as to its status differ, from rare, or possibly rare, to not uncommon.

Population justification
The global population size has not been quantified, but the species is described as rather frequent (Konig et al. 1999).

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

Ecology
This species favours forest edge and remnants, especially on coasts, as well as clove plantations.

Threats
Forest destruction in the Sundaic lowlands of Indonesia has been very extensive, but very few data on this phenomenon are available from Simeulue. The tolerance of secondary and edge habitats shown by this species renders it unlikely to be under immediate threat.

Conservation Actions Underway
CITES Appendix II. Conservation Actions Proposed
Conduct research on the species as it remains very poorly studied. Determine its status and abundance, and assess threats to the species. Consider other conservation actions subsequently. Protect significant areas of suitable forest, in both strictly protected areas and community led multiple use areas.
