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.
|Previously published Red List assessments:||
|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.|
|Continuing decline in area of occupancy (AOO):||Unknown|
|Extreme fluctuations in area of occupancy (AOO):||No|
|Estimated extent of occurrence (EOO) - km2:||5800|
|Continuing decline in extent of occurrence (EOO):||Unknown|
|Extreme fluctuations in extent of occurrence (EOO):||No|
|Continuing decline in number of locations:||Unknown|
|Extreme fluctuations in the number of locations:||No|

|Population:||The global population size has not been quantified, but the species is described as not uncommon (Konig et al. 1999).
Trend Justification: The population is suspected to be in decline owing to on-going habitat destruction.
|Current Population Trend:||Decreasing|
|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.|
|Continuing decline in area, extent and/or quality of habitat:||Unknown|
|Generation Length (years):||3.7|
|Movement patterns:||Altitudinal Migrant|
|Major Threat(s):||Forest loss is accelerating on the Andamans, owing to development of the coastline and possibly small-scale agricultural encroachment.|
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.
