A male and female pair of the pink-necked green pigeon (Treron vernans), a species of bird from the pigeon and dove family, Columbidae. It is a common species of Southeast Asia, found from Myanmar and Vietnam south through to the major islands of Indonesia and the Philippines (where it is called "punay"). It is a medium-sized pigeon with predominantly green plumage; only the male has the pink neck that gives the species its name. The species lives in a wide range of forested and human-modified habitats and is particularly found in open habitats. Its diet is dominated by fruit, in particular figs. Pairs lay two eggs in a flimsy twig nest in a tree, shrub, or hedge, and work together to incubate the eggs and raise the chicks. The species is thought to be an important disperser of fruit seeds. The species has adapted well to human changes to the environment, and can be found in crowded cities as long as fruiting trees are present. It is not considered to be at risk of extinction.

These male and female pair usually appear and rest on the same tree the moment the sun rises in the east. They stay there for about an hour before flying elsewhere and it is like a routine to them.
