Ducula
41 species
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.
Imperial pigeons are found in forests of southern Asia, New Guinea, northern Australia and the Pacific islands. Many species are nomadic, travelling long distances to exploit seasonal fruit sources. Some undertake migrations and all are strong fliers. Because of habitat loss and predation, species of Ducula are amongst the most threatened of avian species globally.
Imperial pigeons are only found in southern Asia, Australia, New Guinea and the Pacific, a distribution from the Himalayas (D. badia) to Tahiti in the South Pacific (D. aurorare). The greatest diversity of birds is in New Guinea. Imperial pigeons are strong fliers, are capable of flight over oceans, and have been successful in colonising islands and archipelagos.
Australia has a poor representation of Ducula amongst its fauna, with only one species breeding on the mainland (D. spilorrhoa). There is no clear explanation why more species of Ducula did not cross the Torres Strait islands to reach mainland Australia. The genus Lopholaimus, comprising only one species may have been well represented on the Australian mainland before European settlement, thus excluding Ducula.
Imperial pigeons are arboreal, and found almost exclusively in forest and woodland habitats where there is availability of fruit bearing trees. About half of the species occupy mountainous forest to elevations of 2500m. Many are found on islands, and live in coastal forests, with a few species inhabiting forest edges or mangroves.
