Description

Nilgiri wood pigeon (Columba elphinstonii)

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. The feet and the base of the bill are red. The species is evolutionarily close to the Ceylon woodpigeon '' Columba torringtoni'' and the ashy wood pigeon '' Columba pulchricollis'' which form a

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. 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. They feed on large fruits and may play an important role in dispersal of the seeds of many forest trees. Fruits of the family

are particularly favoured and most of their food is gathered by gleaning on the outer twigs of the middle and upper canopy. They have been recorded ingesting soil that may provide mineral nutrients or aid digestion. 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.
