The tooth-billed pigeons are the only genus (Didunculus) of the subfamily Didunculinae, in the pigeon and dove family, (Columbidae). It has no close living relatives, but it has been shown to be genetically close to the dodo, [2] and the genus name Didunculus means "little dodo". [3] The jaw and tongue structure, and the superficially parrotlike bill have suggested a relationship to the parrots, but these features have arisen from its specialised diet rather than any real relationship.

Species

Two species are known:

The Tongan tooth-billed pigeon (Didunculus placopedetes bebefolis) is only known from subfossil [4] remains in several archaeological sites in Tonga dating 2700–2850 BP [5] and now extinct. The tooth-billed pigeon (Didunculus strigirostris) from Samoa is critically endangered. [6]

Notes

  1. The name has long been erroneously been credited to Peale, 1848, but it was actually first published by William Jardine in 1845. Because the name was also first published in synonymy with Jardine's Gnathodon, Didunculus must be credited to Jardine following Article 50.7 of the ICZN, even though it is credited to Titian Peale in the text.

<span class="mw-page-title-main">Dodo</span> Extinct large flightless pigeon from Mauritius

The dodo is an extinct flightless bird that was endemic to the island of Mauritius, which is east of Madagascar in the Indian Ocean. The dodo's closest relative was the also-extinct and flightless Rodrigues solitaire. The two formed the subfamily Raphinae, a clade of extinct flightless birds that were a part of the family which includes pigeons and doves. The closest living relative of the dodo is the Nicobar pigeon. A white dodo was once thought to have existed on the nearby island of Réunion, but it is now believed that this assumption was merely confusion based on the also-extinct Réunion ibis and paintings of white dodos.

<span class="mw-page-title-main">Columbidae</span> Family of birds

Columbidae is a bird family consisting of doves and pigeons. It is the only family in the order Columbiformes. These are stout-bodied birds with short necks and short slender bills that in some species feature fleshy ceres. They primarily feed on plants, and can be taxonomically divided amongst granivores, that feed mostly on the ground on seeds, and frugivores, that feed mostly on fruits, from branches. The family occurs worldwide, often in close proximity with humans, but the greatest variety is in the Indomalayan and Australasian realms.

<span class="mw-page-title-main">Rodrigues solitaire</span> Extinct, flightless bird that was endemic to Rodrigues

The Rodrigues solitaire is an extinct flightless bird that was endemic to the island of Rodrigues, east of Madagascar in the Indian Ocean. Genetically within the family of pigeons and doves, it was most closely related to the also extinct dodo of the nearby island Mauritius, the two forming the subfamily Raphinae. The Nicobar pigeon is their closest living genetic relative.

<span class="mw-page-title-main">Nicobar pigeon</span> Species of bird

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.

<span class="mw-page-title-main">Raphinae</span> Extinct subfamily of birds

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.

The Choiseul pigeon is an extinct species of bird in the pigeon and dove family, Columbidae. It was endemic to the island of Choiseul in the Solomon Islands, although there are unsubstantiated reports that it may once have lived on several nearby islands. The last confirmed sighting was in 1904. Other common names were Solomons crested pigeon, Solomon Islands crowned-pigeon and Kuvojo.

<span class="mw-page-title-main">Mauritius sheldgoose</span> Extinct species of bird

The Mauritius sheldgoose, also known as the Mauritius shelduck, is an extinct species of sheldgoose that was endemic to the island of Mauritius. While geese were mentioned by visitors to Mauritius in the 17th century, few details were provided by these accounts. In 1893, a carpometacarpus wing-bone and a pelvis from the Mare aux Songes swamp were used to name a new species of comb duck, Sarcidiornis mauritianus. These bones were connected to the contemporary accounts of geese and later determined to belong to a species related to the Egyptian goose and placed in the sheldgoose genus Alopochen. The Mauritius and Réunion sheldgoose may have descended from Egyptian geese that colonised the Mascarene islands.

<span class="mw-page-title-main">Mauritius blue pigeon</span> Extinct bird in the family Columbidae from Mauritius

The Mauritius blue pigeon is an extinct species of blue pigeon formerly endemic to the Mascarene island of Mauritius in the Indian Ocean east of Madagascar. It has two extinct relatives from the Mascarenes and three extant ones from other islands. It is the type species of the genus of blue pigeons, Alectroenas. It had white hackles around the head, neck and breast and blue plumage on the body, and it was red on the tail and the bare parts of the head. These colours were thought similar to those of the Dutch flag, a resemblance reflected in its French common name, Pigeon Hollandais. The juveniles may have been partially green. It was 30 cm (12 in) long and larger and more robust than any other blue pigeon species. It fed on fruits, nuts, and molluscs, and was once widespread in the forests of Mauritius.

<span class="mw-page-title-main">Tooth-billed pigeon</span> Species of bird

The tooth-billed pigeon, also known as the manumea, is a large pigeon found only in Samoa. It is the only living species of genus Didunculus. A related extinct species, the Tongan tooth-billed pigeon, is only known from subfossil remains in several archeological sites in Tonga. The tooth-billed pigeon is the national bird of Samoa and featured on the 20 tālā bills and the 50 sene pieces of the 2008/2011 series. Native only to Samoa's primary rainforest, it is considered to be endangered, with only a few hundred individuals thought to remain in existence.

<span class="mw-page-title-main">Bird extinction</span> Typically human-caused eradication of entire avian species

Bird extinction is the complete elimination of all species members under the taxonomic class, Aves. Out of all known bird species,, 159 (1.4%) have become extinct, with 226 (2%) being critically endangered. There is a general consensus among ornithologists that if anthropogenic activities continue as current trends suggest, one-third of all bird species, and an even greater proportion of bird populations, will be rendered extinct by the end of the 21st century.

<span class="mw-page-title-main">Spotted green pigeon</span> Extinct species of bird

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.

Bountyphaps obsoleta is an extinct species of pigeon. It was described in 2008 as a new genus and species from subfossil remains found on Henderson Island in the Pitcairn Group of southeastern Polynesia. Additionally, an indeterminate species, possibly the same as B. obsoleta, has been found in the Gambier archipelago.
