The Pink-necked Green Pigeon - Treron vernans is found in Thailand, Vietnam, Cambodia, Malaysia, Indonesia and the Phillippines. 

Its natural habitats are subtropical or tropical moist lowland Forests, subtropical or tropical mangrove forests, and subtropical or tropical moist montane forests.

Pink-necked Green Pigeons eat mainly fruits. Figs are their favourite, but they also eat palm fruit and berries, and nibble on buds. 

Like other Green Pigeons, they are arboreal and seldom come the ground except to drink, although they may snack on berries of low bushes. They forage most actively in the early morning. Although they may feed in flocks of up to 30 in a fruiting tree, males especially may defend small patches from others in the flock.

Pink-necked Green Pigeons tend to roost together and a site may attract hundreds of birds from a wide area and become a traditional roost. Favoured roosting sites are tall trees in swamps and mangroves. But they nest alone and not in large colonies.

Pigeons and doves do not have well-developed oil glands, which in other birds are used to waterproof their feathers. Instead, they have special plumes scattered throughout their body which disintegrate to produce a powder which cleans and lubricates the feathers.

Breeding is late March to late July with 1 to 2 white eggs laid. Both parents take turns incubating them and both raise the young. Fledglings may remain near the nest for up to 1 week.

Numbers are declining, they used to be far more common in the past. They are still hunted in parts of Asia, usually shot as they gathered in large flocks in the evening at their communal roosts. Besides this hunting pressure, they are probably also affected by the disappearance of their food trees. They have adapted to non-forest habitats such as mangroves, cultivated land in rural as well as urban areas.
