|Scientific Name:||Garrulax leucolophus|
|Species Authority:||(Hardwicke, 1815)|
|Taxonomic Notes:||Garrulax leucolophus (Sibley and Monroe 1990, 1993) has been split into G. leucolophus and G. bicolor following Collar (2006).|
|Red List Category & Criteria:||Least Concern ver 3.1|
|Facilitator/Compiler(s):||Butchart, S., Bird, J.|
This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

|Population:||The global population size has not been quantified, but the species is described as generally common (del Hoyo et al. 2007).
Trend Justification: The population is suspected to be in decline owing to ongoing habitat destruction and fragmentation.
|Current Population Trend:||Decreasing|
