This species has a small range, being limited to a number of small islands. Population declines are suspected to be occurring owing to habitat loss, and the situation requires careful monitoring for any future increases in the rate of human development. However, the species's habitat and population are not regarded as severely fragmented or restricted to a few locations. It is therefore currently considered Near Threatened.
|Previously published Red List assessments:|
|Range Description:||Dicrurus andamanensis is endemic to the Andaman archipelago, India, and Coco Island, Myanmar, where it is a common resident of forests (BirdLife International 2001).|
|Range Map:||Click here to open the map viewer and explore range.|
|Population:||The population size of this species has not been quantified, but it is described as common.|
Trend Justification: Evidence of increasing human population pressure and development within the species's range suggests that slow declines are likely to be occurring.
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||This species inhabits monsoon forests in lowlands and hills, where it is described as common.|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Generation Length (years):||2.8|
|Movement patterns:||Not a Migrant|
|Major Threat(s):||Although its range is very small, forested habitat is relatively intact on the Andamans and insufficiently disturbed or fragmented to be of immediate concern. However, there are signs that pressure on forests is increasing on the islands through increasing human populations and consequent conversion of habitat to cultivation, grazing, increased logging and development.|
Conservation Actions Underway
No targeted conservation actions are known for this species, although some of its habitat is protected.
Conservation Actions Proposed
Monitor rates of population change and habitat trends. Conduct ecological studies to determine habitat requirements, tolerance of secondary habitats and response to fragmentation. Ensure the protection of remaining forest habitats on the Andaman Islands.
