Psilopogon viridis
These birds are primary cavity nesters, chiseling out the trunk or a vertical branch of tree with a round entry hole. They breed from December to July, sometimes raising two broods. Favoured nest trees in urban areas include gulmohur (Delonix regia) and African tulip (Spathodea campanulata). These nest holes may also be used as roosts. They may reuse the same nest tree each year but often excavate a new entrance hole.
These barbets play an important role in forests as seed dispersal agents. They also visit the flowers of Bombax for nectar and may be involved in pollination.
These barbets are arboreal and will rarely visit the ground. They obtain most of the water they need from their fruit diet. When water is available in a tree hole, they will sometimes drink and bathe.
Their fruit eating makes them a minor nuisance in fruit orchards although they are noted as having a beneficial effect in coffee plantations.
A species of tick in the genus Haemaphysalis is known to be specific in its parasitic association with this species and some species of Leucocytozoon are known to be blood parasites. Some species of Haemaphysalis are known to carry the virus responsible for the Kyasanur forest disease. Shikras have been recorded preying on adults.
Salim Ali noted that some birds may call in the night during the breeding season, but this has been questioned by other observers such as K K Neelakantan who note that these birds appear to be strictly diurnal.
