The Nilgiri laughingthrush (Strophocincla cachinnans ) is a species of laughingthrush endemic to the high elevation areas of the Nilgiris and adjoining hill ranges in Peninsular India. The mostly 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. In the past the species was considered to have two subspecies, the nominate form in the Nilgiris (earlier called the black-chinned laughingthrush or rufous-breasted laughingthrush) and jerdoni (which is now treated as a full species, the Banasura laughingthrush) with a grey upper breast and found in the Brahmagiris of Coorg and Banasura range of Wayanad. They are omnivorous, feeding on a range of insects, berries and nectar.

starts withThis laughingthrush is about 24 cm long with a rufous underside and a dark olive grey upper body. The crown is slaty brown and there is a jagged and broad white supercilium margined with black. The throat, lores and a streak behind the eye are black. The tail is olive brown. The iris is reddish brown and the legs and bill are black. The upper breast is grey in the subspecies jerdoni and can appear somewhat like fairbanki although the throat of the latter is grey and the two do not overlap in range. It is unmistakable in plumage although at a quick glance it can be mistaken for an Indian scimitar babbler.
The Nilgiri laughingthrush lives in dense forest patches on the Nilgiri and Wayanad ranges above the elevation of 1,200 m (3,900 ft). It forages along the forest edge singly or in small groups low in the trees and sometimes on the ground. They are active in the early morning and late afternoon and are extremely vocal. While one bird calls in a series of loud ascending and descending nasal notes, another in a nearby bush produces a series of sharp kek notes. They feed on the nectar of Lobelia excelsa and Rhododendron in winter. When Strobilanthes is in bloom, the birds feed on its nectar as well as its petals. They feed on the fruits of Ilex spp., Solanum auriculatum, Eurya japonica, Rhamnus wightii, Pyrus baccata, Rubus spp., Mahonia leschenaultii and Rhodomyrtus tomentosa ("hill guava"). Insects are crushed before swallowing and sometimes battered against a hard substrate. Small tree-frogs are sometimes taken. Large fruits are sometimes held under their foot and torn apart. They tend to forage on the open ground at dawn and dusk and mostly glean from vegetation during the rest of the day.
The Nilgiri laughingthrush nests from February to the beginning of June. The nest is a cup placed at about 1–2 m (3 ft 3 in – 6 ft 7 in) above the ground in a clump of dense undergrowth, often close to a stream or marsh in the edge of a shola. The male as well as the female build the nest. The inside of the cup nest is lined with hair and fine material and nearly 50% of the nest weight is made up of mosses. The eggs are laid within a few days of completing the nest construction, which can take from 5 to 18 days (average of 13 days). Nests built later in the season tend to be constructed more rapidly. The clutch consists of 2 greenish blue eggs with brown blotches and streaks. The adults tear up and destroy the nest after the young birds fledge or if the nest is predated. The eggs are about 2.3 to 2.7 cm (0.92 to 1.08 in) long and 1.9 to 2.0 cm (0.74 to 0.8 in) wide. Incubation begins after the second egg is laid and both parents take turns until the chick hatches on the 16th or 17th day. If one of the eggs fails to hatch, the egg is left alone and not removed as in some bird species. The young are fed with insects during their early stages and berries such as Rubus at a later stage. The faecal sacs produced by the young are swallowed by the parents. The young fledge after 15–18 days but continue to remain nearby for about three weeks. Predators of the eggs and young include the Indian jungle crow and the greater coucal.
The distribution of the species is restricted to a small area which is prone to habitat destruction leading to its status being considered as endangered.
