The black-chinned laughingthrush (Trochalopteron cachinnans) is a species of laughingthrush endemic to the high elevation areas of the Nilgiris and adjoining hill ranges in Peninsular India. The mosty rufous underparts, olive brown upperparts, a prominent white eyebrow and a black throat make it unmistakable. It is easily detected by its loud series of nasal call notes and can be hard to spot when it is hidden away inside a patch of dense vegetation. The species has a confusing taxonomic history, leading to a range of names. There are two subspecies, the nominate form in the Nilgiris (earlier called the Nilgiri laughingthrush or rufous-breasted laughingthrush) and jerdoni (earlier called the Banasore laughingthrush) with a grey upper breast and found in the Brahmagiris of Coorg and Banasur
