Palani Laughingthrush
Montecincla fairbanki
This is the only montane laughingthrush in its range and hence unmistakable. It has dull olive-brown upperparts, a grey-streaked white breast, and a rufous-chestnut lower breast and belly. The most striking characteristic is the white eyebrow, flaring in front of the eye over a dark eye-line. Found in stunted montane forests, tea estates, and wooded second growth, in pairs or noisy flocks, producing a melodious “pe-kee-ke” song and several other chatters intermingled with musical notes. Heard more often than seen; its songs and calls are usually the first indication of its presence.
Identification
This species has a dark grey-brown crown and narrow dark grey eyestripe with a broad white supercilium above it. This supercilium extends behind the eye in this species but stops above the eye in the closely related meridionalis. The throat is distinctly grey unlike in the black-chinned laughingthrush found north of the Palghat Gap and continues into the upper breast. The grey of the upper breast is faintly streaked in brown. The lower breast and belly is rusty brown and the upper parts are olive brown. The bill is browner and not as dark grey as in the black-chinned. The Ashambu laughingthrush (M. meridionalis) which was earlier treated as a subspecies has greyer upper plumage, paler crown and the centre of the belly is white with chestnut brown on the flanks and vent. The iris is dark red or red-brown. The sexes are indistinguishable in the field.
Taxonomy
This species was described from the Kodaikanal region on the basis of a specimen obtained by Rev. Samuel Bacon Fairbank and came to be called the Pulney laughing-thrush. The lack of the black chin of jerdoni was noted even when this species was first described but it was made into a subspecies under jerdoni in the second edition of The Fauna of British India, Including Ceylon and Burma in 1922 by Stuart Baker. In 1880 Blanford described meridionale based on a specimen obtained by F. W. Bourdillon. The close relationship of meridionale and fairbanki was noticed by William Ruxton Davison in 1883. The current regrouping of the forms, considering the Palghat Gap as a biogeographic barrier and giving importance to the chin colour, was introduced in 2005 by Pamela C. Rasmussen and Anderton. A study published in 2017 found that the species was best placed in a new genus Montecincla and that based on the divergence, meridionale is best treated as a full species.

Range and habitat
This species is restricted south of the Palghat Gap with the main distribution range in the higher regions (above 1,100 metres (3,600 ft)) of the Palani Hills extending into the Annamalai Hills in western Tamil Nadu and Munnar in Kerala. The nominate subspecies is found north of the Achankovil gap while meridionale is found in the hills to the south of it. In the Palni Hills, their densities varied across locations ranging from 1.4 birds per hectare at Kukkal, 0.5/ha at Poombarai, 0.33/ha at Kodaikanal Botanical gardens, 0.16/ha on the golf course and 0.22/ha at Paricombai.

Behavior
They are found in pairs and small groups and they sometimes join mixed-species feeding flocks. They feed on the nectar of flowers of Lobelia excelsa, Rhododendron and Strobilanthes species. They also feed on the petals of some flowers such as Strobilanthes and the fruits of a range of plants including Viburnum, Eurya, Rubus and Rhodomyrtus tomentosa.<p>The breeding season is December to June but peaking in April and May. The nest is a cup of grass with moss and lined with fine fibre placed in a low fork hidden in dense vegetation. The usual clutch is two blue eggs with reddish markings and indistinguishable from those of the black-chinned laughingthrush. When the nest is predated or after the young fledge, the nest is destroyed. The nests of other birds in the vicinity may also be torn up by the parent birds. Unhatched eggs may also be eaten by the parent birds.<p>The contact calls are very loud series of steeply ascending notes pee-koko... pee-koko followed by more abrupt notes. Numerous other vocalizations such as a low kweer calls are produced in other behavioural contexts. Some calls appear to be antiphonal duets.

Other Birds
Magdalena Antbird
Sipia palliata
Medium-sized, short-tailed antbird with a bright red eye. Has slate gray head and breast, black throat, brown belly and upperparts, and whitish dotted wings. Female is similar but has a white barred throat and buffy dots in the wings. No overlap with the similar Dull-mantled or Esmeraldas Antbirds. Often found in pairs, typically in rocky shaded ravines along streams in foothills. Often quite vocal; song a strong, relatively high-pitched series of notes “fee-feet-feet-FEET-feteu-feek!”, and call is a harsh “FEeuh.”
Buru Golden-Bulbul
Hypsipetes mysticalis
A thrush-sized olive-colored songbird with a long, fairly heavy bill. Plumage uniform olive-green except for narrow yellow chin, yellow patch between the bill and the eye, and partial yellow eye-ring above the eye. Pairs or small groups occupy forest, degraded forest, edges, and plantations from sea level to foothills. Unmistakable; limited to the island of Buru. Song starts with several soft “pip” or “chek” notes, then explodes in a series of variable whistles, e.g. “WEE-WEE-WEE-WEK-pewee-pewee-WEE-WEE.” Calls include dry “chek” notes and rasping “chirrrik” calls.
Chestnut Rail
Gallirallus castaneoventris
Secretive, very large rail (approaching Australasian Swamphen in size), only likely to be seen in and near mangroves, foraging in the mud along tidal creeks and estuaries in northern Australia. Olive brown above, chestnut below, with gray head, chalky yellow bill, and yellow legs. Calls loudly, with grunts and wild honking squawks.
