The purple-winged ground dove (Paraclaravis geoffroyi) is a critically endangered species of dove, native to the Atlantic forest, mainly near bamboo, in south-eastern Brazil, far eastern Paraguay, and northern-eastern Argentina (Misiones only). It is threatened by habitat loss and possibly the wild bird trade, and could potentially even be extinct due to its specialized requirements.
It is a nomadic species that follows the masting events of certain species of Guadua bamboo of the Atlantic forest, namely takuarusu ( G. chacoensis ) and yatevó ( G. trinii ); it shares its trait with its closest relative, the maroon-chested ground-dove (Paraclaravis mondetoura), which instead specializes on Andean bamboo. This specialized lifestyle may be what led to such a dramatic decline in the species' population despite its relatively large former range, with the mass deforestation of the Atlantic forest in the late 20th century triggering an Allee effect akin to its extinct relative the passenger pigeon (Ectopistes migratorius), which also depended on masting events of nut-producing trees. [2]
There have been no verifiable observations of the species since 1985, [3] and it could very well be extinct, although numerous unverified records have been made since then, the most recent being a 2017 sighting of an individual in Argentina in a patch of G. trinii. Extinction models are divided on whether the species is extant or not; when only photographs, specimens and recordings are considered, the species is predicted to have gone extinct during the 2000s, but models that incorporate sight records support the species still being extant. [2]
The species can be easily confused with the blue ground dove (Claravis pretiosa) which it occurs in sympatry with, in poor observation conditions, contributing to the disputed legitimacy of more recent observations.The violaceous quail-dove (Geotrygon violacea), another sympatric species with similar habitat requirements, has still been recorded in the region since the 1980s, raising further doubts over the survival of P. geoffroyi; mist netting efforts in the area have regularly captured G. violacea, but no P. geoffroyi. The nomadic nature of P. geoffroyi adds more doubt to the prospect of its survival, as it is unlikely that a nomadic species such as it would persist in a single location or travel over a large area unseen. However, the extremely secretive nature of the species and the lack of call recordings until recently indicate that the species may have naturally low detectability, especially outside of bamboo masting events. [2]
If it is still extant, the total population is estimated to number 50 to 249 individuals. Areas in which the species could still potentially persist include the Serra do Mar of Brazil and most of Misiones province of Argentina, as these areas are expansive and undersurveyed compared to the rest of the Atlantic Forest remnants. [2] [4]
The species was kept and bred in the Brazilian aviculture community from the 1970s to the late 1980s, reaching a high of over 150 captive birds. However, new regulations on bird breeding imposed by IBAMA in the 1970s and 1980s led to the disbanding of most dove-breeding groups, with captive individuals being sent to IBAMA-authorized breeders who had little knowledge of how to take care of the birds, compounded by the lack of knowledge of the species' true endangerment in the wild at the time, and the last captive individuals are thought to have died out by the mid-1990s without producing any offspring, marking the end of one of the best chances to save the species from extinction. Sound recordings of the species have been acquired from former dove breeders and may be crucial at detecting the species in the wild on future surveys. [2] [4]
The passenger pigeon or wild pigeon is an extinct species of pigeon that was endemic to North America. Its common name is derived from the French word passager, meaning "passing by", due to the migratory habits of the species. The scientific name also refers to its migratory characteristics. The morphologically similar mourning dove was long thought to be its closest relative, and the two were at times confused, but genetic analysis has shown that the genus Patagioenas is more closely related to it than the Zenaida doves.
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.
The Luzon bleeding-heart, bleeding-heart dove, bleeding-heart pigeon or punay is one of a number of species of ground dove in the genus Gallicolumba that are called "bleeding-hearts". The native name in Tagalog is punay. It is also known as paloma de punalada 'stabbed pigeon'. The Luzon Bleeding-heart is the species in which the "blood" feature is most pronounced, with the reddish hue extending down the belly, furthering the illusion of blood having run down the bird's breast.
The Mindoro bleeding-heart, also referred to as kulo-kulo, la-do, manatad, manuk-manuk, punay, and puñalada by the Mangyan, is a species of ground dove native solely to the island of Mindoro in the Philippines. It is critically endangered and threatened by habitat loss largely motivated by marble extraction. Due to its biological line and its survival status, it has been listed as an EDGE species by the Zoological Society of London.
The pink pigeon is a species of pigeon in the family Columbidae endemic to Mauritius. The pink pigeon nearly became extinct in the 1970s and the 1990s and is still very rare. It is the only Mascarene pigeon that has not become extinct. It was on the brink of extinction in 1991 when only 10 individuals remained, but its numbers have increased due to the efforts of the Durrell Wildlife Conservation Trust since 1977. While the population remains at below 500 birds as of 2011, the IUCN downlisted the species from Critically endangered to Endangered on the IUCN Red List in 2000, and then downlisted it again to Vulnerable in 2018.
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.
The blue ground dove is a small New World tropical dove. It is a resident breeder from southeastern Mexico to northwestern Peru and northern Argentina, and on Trinidad in the Caribbean.
The thick-billed ground dove is an extinct dove species of the family Columbidae.
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.
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.
The maroon-chested ground dove is a species of bird in the family Columbidae. It is found in Bolivia, Colombia, Costa Rica, Ecuador, El Salvador, Guatemala, Honduras, Mexico, Panama, Peru, and Venezuela.
Geotrygon is a bird genus in the pigeon and dove family (Columbidae). Its members are called quail-doves, and all live in the Neotropics. The species of this genus have ranges from southern Mexico and Central America to the West Indies and South America. Quail-doves are ground-dwelling birds that live, nest, and feed in dense forests. They are remarkable for their purple to brown coloration with light-and-dark facial markings.
The violaceous quail-dove is a species of bird in the family Columbidae. It is found in Argentina, Bolivia, Brazil, Colombia, Costa Rica, Guyana, Nicaragua, Panama, Paraguay, Peru, Suriname, and Venezuela.
The spotted bamboowren is a species of suboscine passerine bird in the tapaculo family Rhinocryptidae. It is the only species placed in the genus Psilorhamphus. It is found in southeastern Brazil, far northeastern Argentina, and possibly Paraguay.
Paraclaravis is a genus that contains two species of doves that live in the Neotropics, with ranges in Middle America and South America. Paraclaravis doves have red eyes and pink legs, and the plumages of the males are primarily light grey-blue, and the females are primarily brown. Both sexes have a series of distinctive spots or bands on the wings. They are fairly arboreal for ground doves. Paraclaravis doves have a distinct fast and rocking flight pattern. They are found alone, in pairs or in small flocks in forests. Both species are generally local and rare, and appears to be associated with flowering bamboo.
