The Nilgiri wood pigeon (Columba elphinstonii) is large pigeon found in the moist deciduous forests and sholas of the Western Ghats in southwestern India. They are mainly frugivorous and forage in the canopy of dense hill forests. They are best identified in the field by their large size, dark colours and the distinctive checkerboard pattern on their nape.

Description

This pigeon appears dark grey and a black and white patterned patch made of white tipped stiff feathers on the back of the neck is distinctive. The mantle is chestnut. The male has a paler grey crown while the female has a darker grey crown with a pale throat. The most confusable other species is the mountain imperial pigeon but that species has paler underwing coverts. [3] The feet and the base of the bill are red. [4] [5]

The species is evolutionarily close to the Ceylon woodpigeon Columba torringtoni and the ashy wood pigeon Columba pulchricollis which form a clade that is basal within the Old World genus Columba. [6] [7] [8] The binomial commemorates Mountstuart Elphinstone (1779–1859).

Distribution

The species is mainly found along the Western Ghats and in the Nilgiri Hills. [3] Although found mainly in the hills, it is sometimes seen at lower elevations within the Western Ghats. [9] A few relict populations survive on the high elevations hills of the peninsula such as the Biligirirangan Hills [10] and Nandi Hills near Bangalore. [11] [12]

Behaviour and ecology

Nilgiri wood pigeons are usually seen singly, in pairs or in small groups, feeding almost entirely in the trees but sometimes descending to the ground to forage on fallen fruits. Although feeding mainly on fruits they have been recorded taking small snails and other invertebrates. [3] The breeding season is March to July during which time they make a flimsy platform of twigs and lay a single white egg which is usually visible from below the nest. [4] They feed on large fruit and may play an important role in dispersal of the seeds of many forest trees. [13] Fruit of the family Lauraceae are particularly favoured and most of their food is gathered by gleaning on the outer twigs of the middle and upper canopy. [14] They have been recorded ingesting soil that may provide mineral nutrients or aid digestion. [15] They often make movements within the forest according to the fruiting seasons of their favourite trees. Their call is a loud langur-like low-frequency hooting "who" followed by a series of deep "who-who-who" notes. [16]

The Malabar trogon is a species of bird in the trogon family. It is found in the forests of India and Sri Lanka. In India it is mainly found in the Western Ghats, hill forests of central India and in parts of the Eastern Ghats. They are insectivorous and although not migratory, may move seasonally in response to rain in hill forest regions. Like in other trogons, males and females vary in plumage. The birds utter low guttural calls that can be heard only at close quarters and the birds perch still on a branch under the forest canopy, often facing away from the viewer making them easy to miss despite their colourful plumage.

The purple sunbird is a small bird in the sunbird family found mainly in South and Southeast Asia but extending west into parts of the Arabian peninsula. Like other sunbirds they feed mainly on nectar, although they will also take insects, especially when feeding young. They have a fast and direct flight and can take nectar by hovering like a hummingbird but often perch at the base of flowers. The males can appear all black in harsh sunlight but the purple iridescence is visible on closer observation or under good light conditions. Females are olive above and yellowish below.

The yellow-browed bulbul, or golden-browed bulbul, is a species of songbird in the bulbul family, Pycnonotidae. It is found in the forests of southern India and Sri Lanka. The yellow-browed bulbul is mainly yellow on the underside and olive above with a distinct yellow brow. They are easily located by their loud calls but tend to skulk within foliage below the forest canopy. While its taxonomic classification has changed over time, it is currently the sole species within the monotypic genus Acritillas which is closely related to Hemixos.

The Indian scimitar babbler is an Old World babbler. It is found in peninsular India in a range of forest habitats. They are most often detected by their distinctive calls which include an antiphonal duet by a pair of birds. They are often hard to see as they forage through dense vegetation. The long curved yellow, scimitar-shaped bills give them their name. It has been treated in the past as subspecies of the white-browed scimitar babbler which is found along the Himalayas but now separated into two species, the peninsular Indian species and the Sri Lanka scimitar babbler.
