Андаманский зеленый голубь Treron chloropterus

A large, dull-green pigeon with a thick pale bill and a gray forehead. The dark olive-green and maroon wings have contrasting yellow lines below the shoulders, and the undertail is dull yellow with green patches. Often flocks in large numbers, and feeds in the canopy on fruits and figs. The song is a distinctive low, nasal whistle.
