Taxonomic note

Garrulax mitratus and G. treacheri (del Hoyo and Collar 2016) were previously lumped as G. mitratus following Sibley and Monroe (1990, 1993).

Population justification: The global population size has not been quantified, but the species is generally described as common (del Hoyo et al. 2007).

Trend justification: The population was suspected to be in slow decline owing to ongoing habitat destruction and fragmentation, but demand for the cagebird trade is now is suspected to be driving a moderately rapid to rapid decline on Sumatra within the most recent three generations. Although the Thailand/Malaysia population is not subject to the same threat, a moderately rapid population decline is nevertheless suspected to be taking place overall.
