Treron or green pigeons, is a genus of pigeons in the Columbidae family. The genus is distributed across Asia and Africa. This genus contains 29 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 fruit, 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.
