This is a list of Columbiformes species by global population. While numbers are estimates, they have been made by the experts in their fields. For more information on how these estimates were ascertained, see Wikipedia's articles on population biology and population ecology.

Columbiformes
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 seeds, fruits, and plants. The family occurs worldwide, but the greatest variety is in the Indomalayan and Australasian realms. The family contains 344 species divided into 50 genera. Thirteen of the species are extinct. In English, the smaller species tend to be called "doves" and the larger ones "pigeons". However, the distinction is not consistent, and does not exist in most other languages. Historically, the common names for these birds involve a great deal of variation between the terms. The bird most commonly referred to as just "pigeon" is the domestic pigeon, which is common in many cities as the feral pigeon. Doves and pigeons build relatively flimsy nests, often using sticks and other debris, which may be placed on bran ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
São Tomé Olive Pigeon
The São Tomé olive pigeon or maroon pigeon (''Columba thomensis'') is an endangered species of pigeon which is endemic to the island of São Tomé off the coast of western Africa. It was described by José Vicente Barbosa du Bocage in 1888. Description The bird is long.BirdLife InternationalSpecies Factsheet ''Columba thomensis'' accessed 17 January 2019 Distribution The olive pigeon occurs in several parts of the island of São Tomé, including the northwest (Chamiço), the central massif (Lagoa Amelia, Zampalma, Nova Ceilão, Bombaim and the valley of Rio Io Grande near Formoso Pequeno), the southwest (valleys of the rivers Xufexufe and Ana Chaves) and in the southeast (west of Água Izé, on Pico Maria Fernandes and north of São João dos Angolares). Conservation and status The continued survival of the São Tomé olive pigeon depends upon stopping habitat loss in the remaining lowland rainforest of São Tomé, as does the survival of three other birds: the São Tom ...

Ducula Galeata Nuku Hiva
''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. Imperial pigeons are found in forests of southern Asia, New Guinea, northern Australia and the Pacific islands. Many species are nomadic, travelling long distances to exploit seasonal fruit sources. Some undertake migrations and all are strong fliers. Because of habitat loss and predation, species of ''Ducula'' are amongst the most threatened of avian species globally. Taxonomy The genus ''Ducula'' was introduced in 183 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endangered Species
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are considered when assessing the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marquesan Imperial Pigeon
The Marquesan imperial pigeon (''Ducula galeata''), also known as the Nukuhiva pigeon or Upe, is a pigeon which is endemic to Nuku Hiva in the Marquesas Islands of French Polynesia. This pigeon is only found in some valleys in the western part of that island. Description This is the largest pigeon outside of the crowned pigeons, as it weighs approximately 900 grams (2 lb). Females, at long, are slightly smaller than males, at in length. Among standard measurements, the wing chord is , the tail is , the bill is and the tarsus is . This species is heavily built with a large bill and long, broad tail. The wings are broad and rounded in shape.David Gibbs, Eustace Barnes & John Cox (2001). ''A Guide to the Pigeons and Doves of the World'' Yale University Press, .

Vulnerable Species
A vulnerable species is a species which has been Conservation status, categorized by the International Union for Conservation of Nature as being threatened species, threatened with extinction unless the circumstances that are threatened species, threatening its survival and reproduction improve. Vulnerability is mainly caused by habitat loss or destruction of the species' home. Vulnerable habitat or species are monitored and can become increasingly threatened. Some species listed as "vulnerable" may be common in captivity (animal), captivity, an example being the military macaw. There are currently 5196 animals and 6789 plants classified as Vulnerable, compared with 1998 levels of 2815 and 3222, respectively. Practices such as cryoconservation of animal genetic resources have been enforced in efforts to conserve vulnerable breeds of livestock specifically. Criteria The International Union for Conservation of Nature uses several criteria to enter species in this category. A tax ...

Rapa Fruit-dove
The Rapa fruit dove (''Ptilinopus huttoni'') is a species of bird in the family Columbidae, which includes pigeons and doves. It is endemic to the island of Rapa Iti in French Polynesia. The species was classified as Critically Endangered by the IUCN Red List in 2018 because of its small population and predicted continued decline. The Rapa fruit dove primarily feeds on fleshy fruit. Its natural habitat is subtropical or tropical moist lowland forests and it has an extent of 30 km2. It is threatened by habitat loss due to deforestation and invasive species. Effective land protection and management could increase the quality of habitat for the species. Additional research into population dynamics and the impact of threats to the species can give a better understanding of the conservation practices needed. Description and range The Rapa fruit dove is approximately 31 centimeters tall, making it a medium-sized dove. It is a colorful bird, with mostly green plumage, especially on i ...
