This forest-associated species is listed as Near Threatened because it is suspected to be undergoing a moderately rapid decline owing to the extensive loss of lowland forests from large areas of the Sundaic lowlands. It is not considered more threatened because it can use secondary habitats.
|Previously published Red List assessments:||
|Range Description:||Batrachostomus stellatus occurs from central peninsular Thailand, Sabah, Sarawak and Peninsular Malaysia, Singapore, Kalimantan (including the North Natuna Islands) and Sumatra (including the Riau and Lingga archipelagos and Bangka Island), Indonesia and Brunei, where it is fairly widespread and common in suitable habitat (BirdLife International 2001).|
Native:Brunei Darussalam; Indonesia; Malaysia; Thailand
|Continuing decline in area of occupancy (AOO):||Unknown|
|Extreme fluctuations in area of occupancy (AOO):||No|
|Estimated extent of occurrence (EOO) - km2:||738000|
|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 common (Cleere 1998).
Trend Justification: Forest destruction in the Sundaic lowlands of Indonesia has been extensive, and the situation is little different in Thailand and Malaysia, but this species's ability to persist in regenerating and second growth habitats suggests it is probably not suffering more than a moderately rapid decline.
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||It occurs in evergreen and secondary forest to at least 500 m (once to 920 m). It feeds on insects in the lower storeys of forest.|
|Continuing decline in area, extent and/or quality of habitat:||Unknown|
|Generation Length (years):||7.5|
|Movement patterns:||Altitudinal Migrant|
|Major Threat(s):||Rates of forest loss in the Sundaic lowlands have been extremely rapid (Kalimantan lost nearly 25% of its evergreen forest during 1985-1997, and Sumatra lost almost 30% of its 1985 cover), because of a variety of factors, including the escalation of logging and land conversion, with deliberate targeting of all remaining stands of valuable timber including those inside protected areas, plus forest fires (particularly in 1997-1998).|
Conservation Actions Underway
No species-specific actions are known, although the species has been recorded from a number of protected areas within its range. Conservation Actions Proposed
Protect areas of lowland forest within the species's range. Enforce restrictions on agricultural encroachment and logging within such protected areas. Generate density estimates to inform a revised population estimate for the species. Estimate population trends by calculating rates of forest loss within its range using satellite imagery and remote sensing techniques.
