Feeding of Nilgiri Wood Pigeon
Nilgiri Wood Pigeon feeds on large fruits and may play an important role in dispersal of the seeds of many forest trees. Fruits 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. 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.
