The green imperial pigeon (Ducula aenea) is a large forest pigeon. The large range extends from Nepal, southern India and Sri Lanka eastwards to southern China, Indonesia and the Philippines.
In 1760 the French zoologist Mathurin Jacques Brisson included a description of the green imperial pigeon in his six volume Ornithologie. He used the French name Le pigeon ramier des Moluques and the Latin Palumbus moluccensis. [2] Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature. [3] When in 1766 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the twelfth edition, he added 240 species that had been previously described by Brisson. [3] One of these was the green imperial pigeon which he placed with all the other pigeons in the genus Columba . Linnaeus included a brief description, coined the binomial name Columba aenea and cited Brisson's work. [4] Brisson believed his specimen had come from the Maluku Islands but the species does not occur there and in 1918 the type locality was designated as the island of Flores in Indonesia. [5] [6] The specific name aenea is from the Latin aeneus meaning "of a bronze colour" or "coppery". [7] This species is now placed in the genus Ducula that was introduced by the English naturalist Brian Houghton Hodgson in 1836. [8] [9]
Eleven subspecies are recognised: [9]
The subspecies D. a. oenothorax is sometimes treated as a distinct species, the Enggano imperial pigeon (Ducula oenothorax). [15] The Nicobar imperial pigeon (Ducula nicobarica) was formerly treated as conspecific. [9] [16]
The green imperial pigeon is a large, plump pigeon, 45 centimetres (18 in) in length. Its back, wings and tail are metallic green. The head and underparts are white, apart from maroon undertail coverts. Sexes are similar. The bird's call is deep and resonant, and is often the first indication of the presence of this treetop species.
This is a forest species which is a widespread resident breeding bird in tropical southern Asia from Nepal [17] [18] and India east to Indonesia. It has several subspecies, including the distinctive Celebes form, chestnut-naped imperial pigeon (Ducula aenea paulina).
This is an arboreal dove, feeding on plant material in the tree canopy. Its flight is fast and direct, with the regular beats and an occasional sharp flick of the wings which are characteristic of pigeons in general. It builds a stick nest in a tree and lays a single white egg. The birds are not very gregarious, but will form small flocks.
The stork-billed kingfisher, is a tree kingfisher which is widely but sparsely distributed in the tropical Indian subcontinent and Southeast Asia, from India to Indonesia. This kingfisher is resident throughout its range.
The black-naped monarch or black-naped blue flycatcher is a slim and agile passerine bird belonging to the family of monarch flycatchers found in southern and south-eastern Asia. They are sexually dimorphic, with the male having a distinctive black patch on the back of the head and a narrow black half collar ("necklace"), while the female is duller with olive brown wings and lacking the black markings on the head. They have a call that is similar to that of the Asian paradise flycatcher, and in tropical forest habitats, pairs may join mixed-species foraging flocks. Populations differ slightly in plumage colour and sizes.
The red-billed firefinch or Senegal firefinch is a small seed-eating bird in the family Estrildidae. This is a resident breeding bird in most of Sub-Saharan Africa with an estimated global extent of occurrence of 10,000,000 km2. It was introduced to Egypt, but the population there has become extinct. It was also introduced to southern Algeria where it is currently expanding northward.
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.
The black-naped oriole is a passerine bird in the oriole family that is found in many parts of Asia. There are several distinctive populations within the wide distribution range of this species and in the past the slender-billed oriole was included as a subspecies. Unlike the Indian golden oriole which only has a short and narrow eye-stripe, the black-naped oriole has the stripe broadening and joining at the back of the neck. Males and females are very similar although the wing lining of the female is more greenish. The bill is pink and is stouter than in the golden oriole.
The hair-crested drongo is an Asian bird of the family Dicruridae. This species was formerly considered conspecific with Dicrurus bracteatus, for which the name "spangled drongo" – formerly used for both – is now usually reserved. Some authorities include the Sumatran drongo in D. hottentottus as subspecies.
The Moluccan king parrot is a parrot endemic to Peleng Island, Maluku, and West Papua in Indonesia. It is sometimes referred to as the Ambon king parrot or Amboina king parrot, but this is potentially misleading, as it is found on numerous other islands than Ambon. The male and female are similar in appearance, with a predominantly red head and underparts, green wings, and blue back and tail. Six subspecies are recognised, but only a few of these are regular in aviculture. In the wild, it inhabits rainforests and feeds on fruits, berries, seeds and buds.
The elegant imperial pigeon, also known as blue-tailed imperial-pigeon, is a large pigeon, with upperparts mainly dark blue-green in colour with an iridescent sheen. Head, neck and underparts are mostly pale grey, with red-brown undertail coverts.
The blue-naped parrot, also known as the blue-crowned green parrot, Luzon parrot, the Philippine green parrot, and locally known as pikoy, is a parrot native throughout the Philippines and the Talaud Islands of Indonesia. It is threatened by habitat loss and trapping for the pet trade.
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 cinnamon-bellied imperial pigeon or cinnamon imperial pigeon is a species of bird in the family Columbidae. It is endemic to the northern Moluccas. Its natural habitat is subtropical or tropical moist lowland forests.
The spotted imperial pigeon, also known as the grey-necked imperial pigeon, is a species of bird in the family Columbidae. Endemic to the Philippines, it lives in forests and forest edges but goes down to the limestone shorelines possibly to feed. It is a vulnerable species threatened by habitat loss and hunting.
The Micronesian imperial pigeon, also known as the Micronesian pigeon, and Belochel is a species of bird in the family Columbidae (doves). It is found in Palau, the Caroline Islands, the Marshall Islands and Nauru. Its habitats include montane forests, secondary forests, forests on beaches, and mangroves. It is threatened by hunting and deforestation, and the IUCN has assessed it as a near-threatened species.
The Pacific imperial pigeon, Pacific pigeon, Pacific fruit pigeon or lupe is a widespread pigeon species 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 spectacled imperial pigeon is a species of bird in the family Columbidae. It is endemic to the Maluku 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. It is a small island specialist where its natural habitats are tropical moist lowland forests and plantations. It is threatened by habitat loss.
The claret-breasted fruit dove is a species of bird in the family Columbidae. It is found in the Moluccas, New Guinea and the Solomon Islands archipelago. Its natural habitat is subtropical or tropical moist lowland forests.
The thick-billed green pigeon is a species of bird in the family Columbidae.
The Nicobar imperial pigeon is a species of bird in the family Columbidae. It is endemic to the Nicobar Islands. Its natural habitats are lowland forests, but it also feeds on fruiting trees in agricultural landscapes.
