The Pacific emerald dove or brown-capped emerald dove (Chalcophaps longirostris) is a pigeon which is a widespread resident breeding bird in the tropical and sub-tropical parts of Indonesia to northern and eastern Australia. It was formerly conspecific with the common emerald dove.
This is a common species in rainforest and similar dense wet woodlands, farms, gardens, mangroves, and coastal heaths. It builds a scant stick nest in a tree up to five metres and lays two cream-coloured eggs. Breeding tends to occur in Australia in spring or early summer in southeastern Australia and late in the dry season in northern Australia.
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 often flies low between the patches of dense forest it prefers, but when disturbed will frequently walk away rather than fly. They are particularly good weavers when flying through forests. When flying they expose a buff underwing and a chestnut colour of their flight feathers.
The Pacific emerald dove is a stocky, medium-sized pigeon, typically 23 to 28 centimetres (9.1 to 11.0 inches) in length. The back and wings are bright emerald green. The flight feathers and tail are blackish, and broad black and white bars show on the lower back in flight. The head and underpants are dark vinous pink fading to greyish on the lower belly. The eyes are dark brown, the bill bright red, and the legs and feet rufous.
The male has a white patch on the edge of the shoulders and a grey crown, which the female lacks. Females will tend to have a browner complexion with a grey mark on the shoulder. Immature birds resemble females but have brown scallops on their bodies and wing plumage.
Pacific emerald doves usually occur singly, in pairs, or in small groups. They are quite terrestrial, often searching for fallen fruit on the ground and spending little time in trees except when roosting. They eat seeds and fruits of a wide variety of plants and are generally tame and approachable. Nevertheless, their tame behaviour does make them vulnerable to mesopredators such as feral cats, with the bird's largest predator being the cassowary that also inhabit the island of New Guinea and north-east Australia. [2]
The call is a low soft moaning cooing consisting of about six to seven coos starting quietly and rising. They also call a nasal "hoo-hoo-hoon". Males perform a bobbing dance during courtship.
The Pacific emerald dove has four sub-species:
A former subspecies, C. l. chrysochlora, has been discontinued and forms re-allocated to C. l. rogersi and C. l. timorensis.
Cassowaries are flightless birds of the genus Casuarius in the order Casuariiformes. They are classified as ratites: flightless birds without a keel on their sternum bones. Cassowaries are native to the tropical forests of New Guinea, The Moluccas, and northeastern Australia.
The rock dove, rock pigeon, or common pigeon is a member of the bird family Columbidae. In common usage, it is often simply referred to as the "pigeon", although this is the wild form of the bird; the pigeons most familiar to people are the domesticated form of the wild rock dove.
The common wood pigeon, also known as simply wood pigeon, is a large species in the dove and pigeon family (Columbidae), native to the western Palearctic. It belongs to the genus Columba, which includes closely related species such as the rock dove. It has a flexible diet, predominantly feeding on vegetable matter, including cereal crops, leading to them being regarded as an agricultural pest. Wood pigeons are extensively hunted over large parts of their range, but this does not seem to have a great impact on their population.
The laughing dove is a small pigeon that is a resident breeder in Africa, the Middle East, South Asia, and Western Australia where it has established itself in the wild after being released from Perth Zoo in 1898. This small long-tailed dove is found in dry scrub and semi-desert habitats where pairs can often be seen feeding on the ground. It is closely related to the spotted dove which is distinguished by a white and black chequered necklace. Other names include laughing turtle dove, palm dove and Senegal dove while in Asia the name little brown dove is often used.
The emerald dove or common emerald dove, also called Asian emerald dove and grey-capped emerald dove, is a widespread resident breeding pigeon native to the tropical and subtropical parts of the Indian Subcontinent and Southeast Asia. The dove is also known by the names of green dove and green-winged pigeon. The common emerald dove is the state bird of the Indian state of Tamil Nadu. The Pacific emerald dove and Stephan's emerald dove were both considered conspecific.
The crested pigeon is a bird found widely throughout mainland Australia except for the far northern tropical areas. Only two Australian pigeon species possess an erect crest, the crested pigeon and the spinifex pigeon. The crested pigeon is the larger of the two species. The crested pigeon is sometimes referred to as a topknot pigeon, a common name shared with the reddish crested Lopholaimus antarcticus of Eastern Australia.
The zebra dove, also known as the barred ground dove, or barred dove, is a species of bird of the dove family, Columbidae, native to Southeast Asia. They are small birds with a long tail, predominantly brownish-grey in colour with black-and-white barring. The species is known for its pleasant, soft, staccato cooing calls.
The peaceful dove is a pigeon native to Australia and New Guinea. The peaceful dove is closely related to the zebra dove of south-east Asia and the barred dove of eastern Indonesia. Until recently, the three were classed as a single species, Geopelia striata, known as peaceful dove or zebra dove.
The white-headed pigeon is a pigeon native to the east coast of Australia.
The Christmas imperial pigeon or Christmas Island imperial pigeon, also known as Black imperial pigeon, Dusky imperial pigeon, Wharton's imperial pigeon, or burong pergam, is a large imperial pigeon endemic to Christmas Island in the northeastern Indian Ocean. It has an overall grey-blue colouration, and juveniles are duller than adults. It makes a soft purring coo sound and a deeper whoo sound comparable to a cow mooing. It lays one glossy white egg per brood, and is possibly somewhat colonial.
The tambourine dove is a pigeon which is a widespread resident breeding bird in woodlands and other thick vegetation in Africa south of the Sahara Desert. Its range extends from Senegal east to Ethiopia and Kenya and southwards through eastern Africa to south-eastern South Africa, but it is absent from the drier areas of south-western Africa. There is a population on the Comoros Islands.
The emerald-spotted wood dove or emerald-spotted dove is a bird of the family Columbidae, resident across eastern and southern Africa. It is a species of open drier deciduous woodland and second growth. It is absent from evergreen rainforests and semidesert areas.
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 Rufescent Imperial Pigeon, also known as the Shining Imperial Pigeon, is a rare species in the world of birds. According to The International Union for Conservative, this species is relatively unknown, and their concern is very minimal. The Union describes that this species is very stable and does not encounter threats from other species The trait of stability is vital in differentiating The Rufescent Imperial Pigeon from the other species confronting threats. This bird in specific does not frequently encounter threats because they are more reserved, quiet birds that tend to remain alone in their habitat. The habitat of these birds allows them to have the frequency of being independent but also gives them the chance to be with other birds. Rooting from the bird family in Columbidae, that also consists of pigeons and doves. In which this family is known for being frugivorous, meaning it primarily feeds on fruit, figs, and seeds.
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 Palau ground dove is a species of bird in the family Columbidae. It is endemic to Palau, living in forests. The IUCN has assessed it as an endangered species.
The Christmas emerald dove, also known as the Christmas green-winged pigeon, is a bird in the pigeon family, Columbidae. It is a distinctive subspecies of the common emerald dove that is endemic to Christmas Island, an Australian territory in the eastern Indian Ocean.
The fruit doves, also known as fruit pigeons, are a genus (Ptilinopus) of birds in the pigeon and dove family (Columbidae). These colourful, frugivorous doves are found in forests and woodlands in Southeast Asia and Oceania. It is a large genus with over 50 species, some threatened or already extinct.
