Green pigeon

Treron is a genus of bird in the pigeon family Columbidae. Its members are commonly called green pigeons. The genus is distributed across Asia and Africa. This genus contains 30 species, remarkable for their green coloration, hence the common name, which comes from a carotenoid pigment in their diet. Green pigeons have diets of various fruits, nuts, and/or seeds. They dwell in trees and occupy a variety of wooded habitats. Members of this genus can be further grouped into species with long tails, medium-length tails, and wedge-shaped tails. Most species of green pigeon display sexual dimorphism, where males and females can be readily distinguished by different colored plumage.

Behaviour
Green pigeons usually live in groups but can be found in mating pairs. These birds like to live in wild environment, away from humans. But nowadays, it has been seen that these live on outskirts of cities and towns together with humans.

Nesting
Their nest is made up of twigs and little branches similar to Common Doves and Pigeons. The height of nest is about 12–20 ft high on trees that camouflage with their colour. One of their nest has been seen on Neem tree in Rajasthan India which exactly match with their body colour.

Eggs are laid 4–5 days after making of nest, and eggs hatch in 15–17 days. After hatching, chicks are fed by both male and female parents.
