Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2012

This species is listed as Near Threatened because it has a small range, within which habitat is declining in quality and extent. However, the species is not restricted to a few locations and is tolerant of considerable habitat modification and so it is not considered to be severely fragmented and is thus not regarded as more threatened. 

Geographic Range [top]

Range Description: Otus balli is an endemic resident in the Andaman islands, India, where it was common, at least early in the twentieth century (BirdLife International 2001). Its current status is unclear, although it appears to be easily found and therefore probably common. There seems little reason to expect its population to be under immediate threat given its tolerance of disturbed areas.

Population [top]

Population: The global population size has not been quantified, but the species is described as not uncommon (Konig et al. 1999).
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: It occurs in trees in semi-open or cultivated areas and around human settlements. It feeds at night on insects and nests in February-April.

Systems: Terrestrial

Threats [top]

Major Threat(s): Forest loss is accelerating on the Andamans, owing to development of the coastline and possibly small-scale agricultural encroachment.

Conservation Actions [top]

Conservation Actions: Conservation Actions Underway
CITES Appendix II.

Conservation Actions Proposed
Protect some areas of lowland forest within the species's range. Enforce restrictions on agricultural encroachment and logging within such protected areas. Compare population densities in human-modified areas and natural forest, and generate a revised population estimate for the species. Encourage developments to be sensitive to the species; it could easily occur within resorts.
