Ecosystem and habitat
These pin-tailed green pigeon species have moderate forest dependence. They normally occur in altitudes from 0 to 1800 meters.The natural ecosystems and habitats of these pin-tailed green pigeon species include tropical and subtropical dry forests, foothill forests, sub-montane forests, evergreen rain forests and secondary forests.
Diet and feeding behavior
The diet of this pin-tailed green pigeon consists mainly of fruits. Wild fruits, drupes, berries and figs are their primary food. These green pigeon species feed in small flocks in the lower canopy of the forest.Reproduction and breeding habits
The breeding season of these pin-tailed green pigeons is mainly from April to June in Himalayan foothills. These species may breed all year round in Indochina. These species are monogamous.The nesting sites include bushes, bamboo clumps or leafy trees. Their nest is a flimsy platform of twigs and sticks placed 2-7 meters above the ground. The clutch contains two white eggs. Both the parents incubate the eggs and take care of the young.
