Green pigeon

Treron is a genus of bird in the pigeon family Columbidae. Its members are commonly called green pigeons, remarkable for their green plumage that lead to their common name, which comes from a carotenoid pigment found in their diets. The genus is distributed across Asia and Africa, and contains 30 species. 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 differences in their plumage. Green pigeons eat various fruits, nuts, and/or seeds. They dwell in trees and occupy a variety of wooded habitats.
