Caloenas is a genus of pigeons. The only living species is the Nicobar pigeon (C. nicobarica).
One or two extinct species are known: the Kanaka pigeon was a large species from New Caledonia and Tonga. It is only known by subfossil remains and was probably hunted to extinction by the early settlers. The spotted green pigeon, another extinct species from an unknown locality, has only a slight similarity to the Nicobar pigeon due to its neck feathers. Ornithologists place it in this genus, but there is not a unanimous agreement. One surviving specimen exists in the Liverpool Museum.
The genus Caloenas was introduced by the English zoologist George Robert Gray in 1840 to accommodate the Nicobar pigeon. [1] [2] The genus name combines the Ancient Greek kalos meaning "beautiful" with oinas meaning "dove". [3]
The genus contains two species: [4]
Sometimes included in the genus is a species that probably became extinct 2,500 years ago:
The avian genus Quiscalus contains seven of the 11 species of grackles, gregarious passerine birds in the icterid family. They are native to North and South America.
Cyanoramphus is a genus of parakeets native to New Zealand and islands of the southern Pacific Ocean. The New Zealand species are often called kākāriki. They are small to medium-sized parakeets with long tails and predominantly green plumage. Most species are forest dwellers, although several of the subantarctic species live in open grassland. The genus formerly had a widely disjunct distribution: while most of the genus ranged from New Caledonia to Macquarie Island, two species were found in the Society Islands, 4,100 km (2,500 mi) away from the rest. Although the islands between these two areas have yielded many bird fossils, undescribed extinct Cyanoramphus have not yet been found on any of them.
The Nicobar pigeon or Nicobar dove is a bird found on small islands and in coastal regions from the Andaman and Nicobar Islands, India, east through the Indonesian Archipelago, to the Solomons and Palau. It is the only living member of the genus Caloenas alongside the extinct spotted green pigeon and Kanaka pigeon, and is the closest living relative of the extinct dodo and Rodrigues solitaire.
The green imperial pigeon is a large forest pigeon. The large range extends from Nepal, southern India and Sri Lanka eastwards to southern China, Indonesia and the Philippines.
Eudyptes is a genus of penguins whose members are collectively called crested penguins. The exact number of species in the genus varies between four and seven depending on the authority, and a Chatham Islands species became extinct in recent centuries. All are black and white penguins with yellow crests, red bills and eyes, and are found on Subantarctic islands in the world's southern oceans. All lay two eggs, but raise only one young per breeding season; the first egg laid is substantially smaller than the second.
Pterocles is a genus of near passerine birds in the sandgrouse family. It includes all the species in the family except for two central Asian species in Syrrhaptes.
The Raphinae are a clade of extinct flightless birds formerly called didines or didine birds. They inhabited the Mascarene Islands of Mauritius and Rodrigues, but became extinct through hunting by humans and predation by introduced non-native mammals following human colonisation in the 17th century. Historically, many different groups have been named for both the dodo and the Rodrigues solitaire, not all grouping them together. Most recently, it is considered that the two birds can be classified in Columbidae, often under the subfamily Raphinae. The first person to suggest a close affinity to the doves was Johannes Theodor Reinhardt, whose opinions were then supported by Hugh Edwin Strickland and Alexander Gordon Melville.
Pyrocephalus is a genus of bird in the tyrant flycatcher family, Tyrannidae.
Conopophaga is a genus of birds in the gnateater family. Its members are found in forest and woodland in South America.
Aplonis is a genus of starlings. These are essentially island species of Indonesia and Oceania, although some species' ranges extend to the Malay Peninsula, southern Vietnam and northeastern Queensland. The typical adult Aplonis starling is fairly uniformly plumaged in black, brown or dark green, sometimes with a metallic gloss. The eye ring is often distinctively coloured. Immatures of several species have dark streaked pale underparts.
Tetrao is a genus of birds in the grouse subfamily known as capercaillies. They are some of the largest living grouse. Feathers from the bird were used to create the characteristic hat of the bersaglieri, an Italian ace infantry formation.
Petrophassa, commonly known as the rock pigeons, is a small genus of doves in the family Columbidae native to Australia, and similar to bronzewing pigeons.
Glaucis is a genus of hummingbird in the family Trochilidae.
The blue pigeons are a genus, Alectroenas, of birds in the dove and pigeon family Columbidae. They are native to islands in the western Indian Ocean.
Dendrocolaptes is a genus of Neotropical birds in the Dendrocolaptinae subfamily.
Lipaugus is a genus of birds in the family Cotingidae.
Tanygnathus is a genus of parrots in the Psittaculini tribe, of the superfamily of Psittacoidea.
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.
The Kanaka pigeon, also known as the great green pigeon or greater maned pigeon, is an extinct species of pigeon. It was probably hunted to extinction by the early settlers of New Caledonia and Tonga around 2,500 years ago. It was described from subfossil remains found at the Pindai Caves of New Caledonia. The specific epithet is a Latinisation of kanaka, the name of the native Melanesian people of New Caledonia. It was about 25% larger than its closest living relative, the Nicobar pigeon.
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.
