The pied imperial pigeon is a relatively large, pied species of pigeon. It is found in forest, woodland, mangrove, plantations and scrub in Southeast Asia, ranging from Myanmar and Thailand, throughout Indonesia and east to the Philippines and the Bird's Head Peninsula in New Guinea. It is mainly found on small islands and in coastal regions. It remains locally common, and is therefore considered to be of least concern by BirdLife International and IUCN.

Ducula is a genus of the pigeon family Columbidae, collectively known as imperial pigeons. They are large to very large pigeons with a heavy build and medium to long tails. They are arboreal, feed mainly on fruit and are closely related to the other genus of fruit-eating doves, Ptilinopus. Both genera display brightly coloured plumage, predominantly green, often with contrasting under-parts of purple, orange or red. Some Ducula have prominently swollen ceres. They have large gapes and swallow seeds whole, playing an important role in seed dispersal.

The white-bellied imperial pigeon is a species of bird in the pigeon family Columbidae. First described by the French ornithologist Charles Lucien Bonaparte in 1854, it is endemic to Indonesia, where it is found on Sulawesi, Buton, Taliabu, Togian, and Peleng.

A large pigeon with a long tail, it measures 42.5–51.5 cm (16.7–20.3 in) long and weighs 510 g (18 oz) on average. Males are mainly green, with pale-grey heads and bellies, chestnut vents, and a pale grey tail band, along with a red orbital ring. Females are nearly identical, but have darker grey areas in their plumage.
The goliath imperial pigeon, also known as the New Caledonian imperial pigeon and the notou, is a species of bird in the family Columbidae. It is endemic to New Caledonia. Its natural habitat is humid forests. The International Union for Conservation of Nature (IUCN) has assessed it as a near-threatened species.

It is endemic to the mountains of Mindoro in central Philippines and is the largest pigeon in the country reaching 50cm in length.
The Pacific imperial pigeon, Pacific pigeon, Pacific fruit pigeon or lupe is a widespread species of pigeon in the family Columbidae. It is found in American Samoa, the Cook Islands, the smaller islands of eastern Fiji, Kiribati, Niue, the smaller satellite islands of Papua New Guinea, Samoa, Solomon Islands, Tokelau, Tonga, Tuvalu, Vanuatu, and Wallis and Futuna Islands.
The grey imperial pigeon is a species of bird in the family Columbidae. It is found in the Sulu Archipelago, Miangas and Talaud Islands. Its natural habitats are tropical moist lowland forests and plantations. It is threatened by habitat loss.

The Torresian imperial pigeon, also known as the nutmeg pigeon, white nutmeg pigeon, Australian pied imperial pigeon or Torres Strait pigeon, is a relatively large, pied species of pigeon. It is found in forest, woodland, savanna, mangrove and scrub in Australia, New Guinea, Aru Islands, islands in the Geelvink Bay, D'Entrecasteaux Islands and Louisiade Archipelago.
The spotted green pigeon or Liverpool pigeon is a species of pigeon which is most likely extinct. It was first mentioned and described in 1783 by John Latham, who had seen two specimens of unknown provenance and a drawing depicting the bird. The taxonomic relationships of the bird were long obscure, and early writers suggested many different possibilities, though the idea that it was related to the Nicobar pigeon prevailed, and it was therefore placed in the same genus, Caloenas. Today, the species is only known from a specimen kept in World Museum, Liverpool. Overlooked for much of the 20th century, it was recognised as a valid extinct species by the IUCN Red List only in 2008. It may have been native to an island somewhere in the South Pacific Ocean or the Indian Ocean, and it has been suggested that a bird referred to as titi by Tahitian islanders was this bird. In 2014, a genetic study confirmed it as a distinct species related to the Nicobar pigeon, and showed that the two were the closest relatives of the extinct dodo and Rodrigues solitaire.
