The White-crested laughingthrush is a member of the family Leiothrichidae, recently split from the Old Word babbler family, Timaliidae. Its scientific name Garrulax leucolophus comes from Latin garrire "to chatter", in reference to its very vocal nature, and from Greek leukós "white" and lophos "crest".
Four subspecies are identified: G. l. leucolophus or Western White-Crested laughingthrush, G. l. patkaicus, G. l. belangeri, and G. l. diardi or Eastern White-crested laughingthrush. A former subspecies, G. l. bicolor, has been re-classified as a species of its own, the endemic Sumatran laughingthrush, on account of its lack of characteristic rufous plumage, different face pattern, and shorter tail.
Like other birds in its genus, G. leucolophus has a stocky build, with strong blackish legs and bill, rounded tail, and voluminous plumage. Its body length averages 30 cm, and its tail ranges from 13 to 15 cm.
It is named after its characteristic white hood and raised crest. It is also easily recognizable due to its broad and elongated black eye-mask. The mantle, back and underparts from the lower breast down are rufescent, contrasting with the white head, throat and upper chest and fading into darker olive-brown on the tail and upper wings. The nape is light gray.
Females look almost identical to males but have a smaller crest, duller mantle, and slightly more pronounced gray on the nape. Juveniles can be identified by their shorter crest and tail, paler mask, brownish nape and brighter mantle.
Subspecies have subtle variations in plumage: patkaicus' mantle is a darker, richer chestnut; belangeri has white extending lower onto the belly and paler underparts; diardi even more so and with a brighter upper mantle.
G. leucolophus has one of the widest ranges of all laughingthrushes and as such is at minimal risk of being threatened by extinction. It is native to the following countries: India, Bangladesh, Nepal, Bhutan, Cambodia, Myanmar, Laos, China, Vietnam, and Thailand. The four subspecies have slightly different distributions:
