Andaman Boobook Ninox affinis
BirdLife is updating this factsheet for the 2016 Red List
Please email us with any relevant information

This species has a small range within which it may be in decline owing to increases in forest clearance and degradation as the human population expands; however, it is not restricted to a few locations and its tolerance of human-modified habitats means that its population is unlikely to be severely fragmented. It is therefore listed as Near Threatened.

Distribution and population
Ninox affinis is endemic to the Andaman and Nicobar archipelagos, India (BirdLife International 2001). Although its tolerance of degraded habitats gives cause for optimism, the species may be declining as human populations on the islands increase.

Population justification
The population size of this species has not been quantified.

Trend justification
The population is suspected to be in slow to moderate decline owing to on-going habitat loss and degradation. The rate of decline is not thought to be more rapid because the species seems to tolerate human-modified habitats.

It is presumed to inhabit mainly lowland forest, and is known to occur in low secondary forest (König and Weick 2008), as well as mangrove forest, settlements, rubber plantations, lightly wooded areas and forest clearings, apparently hawking insects at dusk.

The human population on larger islands in the Andaman group is rising rapidly and habitat is consequently under pressure from agriculture, grazing and logging.

Conservation Actions Underway
None are known. Conservation Actions Proposed
Given the small range of this species it requires research and monitoring to assess its conservation needs. As a precaution, protect significant areas of suitable forest, in both strictly protected areas and community-led multiple use areas.
