The White-crested Laughingthrush (Garrulax leucolophus) is a member of the Leiothrichidae family. It is found in forest and scrub from the Himalayan foothills to Indochina. It formerly included the Sumatran Laughingthrush as a subspecies, but unlike that species the plumage of the White-crested Laughingthrush is rufescent-brown and white, and the black mask is relatively broad. Garrulax leucolophus leucolophus: W Himalayas to Nepal, Sikkim, Bhutan and Assam (Mishmi Hills. Garrulax leucolophus patkaicus: S Assam (s of the Brahmaputra) to n Myanmar and nw Yunnan. Garrulax leucolophus belangeri: S Myanmar and sw Thailand (valley of Mekong River). Garrulax leucolophus diardi: SE Myanmar to sw Yunnan, peninsular Thailand and Indochin
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.
