Mentawai Scops-owl Otus mentawi

Justification
There are some indications that this species has a moderately small population, occupying a small range, which are both in decline owing to human pressures on forest. However, little is currently known about the species's population size and structure, and the impact of potential threats, and its tolerance of habitat modification means that it is unlikely to be severely fragmented. It is therefore listed as Near 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 mentawi is endemic to larger islands of Mentawai, off west Sumatra, Indonesia (BirdLife International 2001). Its status is poorly known, but it may be locally common. Declines are likely owing to habitat conversion, but its ability to persist in human-modified habitats suggests that it is not immediately threatened.

Population justification
This species occupies a few small islands and consequently its population is thought to be moderately small. It is placed in the band 10,000-19,999 mature individuals, equating to 15,000-29,999 individuals in total, rounded here to 15,000-30,000 individuals. This preliminary estimate requires clarification.

Trend justification
The population is suspected to be in decline owing to on-going habitat destruction, although the species appears tolerant of human-altered habitats (del Hoyo et al. 1999).

Ecology
It occurs in lowland forest and secondary growth, including around villages.

Threats
Forest destruction owing to agricultural expansion and logging operations in the Sundaic lowlands of Indonesia has been extensive, but the situation in the range of this species is poorly known.

Conservation Actions Underway
CITES Appendix II. Conservation Actions Proposed
Surveys are required to clarify this species's status, determining its dependence on forest and the current rates of deforestation on the Mentawai islands. Conduct awareness programmes to discourage hunting. Protect significant areas of suitable forest, in both strictly protected areas and community-led multiple use areas.
