The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is an inventory of the global conservation status and extinction risk of biological species. A series of Regional Red Lists are produced by countries and organizations, which assess the risk of extinction to species within a political management unit.
Corvidae is a cosmopolitan family of oscine passerine birds that contains the crows, ravens, rooks, magpies, jackdaws, jays, treepies, choughs, and nutcrackers. In colloquial English, they are known as the crow family or corvids. Currently, 135 species are included in this family. The genus Corvus containing 47 species makes up over a third of the entire family. Corvids (ravens) are the largest passerines.
The Eurasian jay is a species of passerine bird in the crow family Corvidae. It has pinkish brown plumage with a black stripe on each side of a whitish throat, a bright blue panel on the upper wing and a black tail. The Eurasian jay is a woodland bird that occurs over a vast region from western Europe and north-west Africa to the Indian subcontinent and further to the eastern seaboard of Asia and down into south-east Asia. Across this vast range, several distinct racial forms have evolved which look different from each other, especially when comparing forms at the extremes of its range.
The brown jay is a large jay native to North and Central America.
The ground tit, Tibetan ground-tit or Hume's ground-tit is a bird of the Tibetan plateau north of the Himalayas. The peculiar appearance confused ornithologists in the past who called it as Hume's groundpecker and still later as Hume's ground jay or Tibetan ground jay assuming that it belonged to the family Corvidae that includes the crows and jays. Although morphologically confusing, the species has since been identified using molecular sequence comparisons as being a member of the tit family (Paridae) and is the only species in the genus Pseudopodoces. It is found in the Tibetan Plateau of China, India, Nepal & Bhutan.
The piapiac is an African bird in the crow family, and is the only member of the genus Ptilostomus. It is most closely related to the Central Asian ground jays.
The koklass pheasant is a species of gamebird, being closely related to progenitive grouse that lived during the Miocene. They are distantly related to pheasants and are most closely related to grouse and turkeys. Koklass are the only species in the monotypic genus Pucrasia. Both the words koklass and pucrasia have been onomatopœically derived from the bird's territorial call.
The conservation status of a group of organisms indicates whether the group still exists and how likely the group is to become extinct in the near future. Many factors are taken into account when assessing conservation status: not simply the number of individuals remaining, but the overall increase or decrease in the population over time, breeding success rates, and known threats. Various systems of conservation status are in use at international, multi-country, national and local levels, as well as for consumer use such as sustainable seafood advisory lists and certification. The two international systems are by the International Union for Conservation of Nature (IUCN) and The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES).
The New Zealand dotterel is a species of shorebird found only in certain areas of New Zealand. It is also called the New Zealand plover or red-breasted dotterel, and its Māori names include tūturiwhatu, pukunui, and kūkuruatu.
The Sumatran ground cuckoo is a large, terrestrial species of cuckoo. It was introduced to Western science in 1879 and was formerly considered conspecific with the Bornean ground cuckoo but was given status as a unique species in 2000. This elusive species was initially known from just eight specimens and evaded notice from 1916 until 1997, when it was rediscovered and photographed by Andjar Rafiastanto. The Sumatran ground cuckoo's diet is thought to consist of invertebrates, small mammals, and reptiles.
This article is a list of biological species, subspecies, and evolutionary significant units that are known to have become extinct during the Holocene, the current geologic epoch, ordered by their known or approximate date of disappearance from oldest to most recent.
The long-billed crow is a crow that is endemic to the Northern Maluku Islands. This crow is large with glossy plumage, a large bill and white irises. It is classified by the International Union for Conservation of Nature as a "near-threatened species".
The Wetar ground dove is a species of bird in the family Columbidae found on Wetar, Indonesia, and on Timor. Its natural habitats are monsoon forests and gallery forests, and possibly woodland and bamboos. Threatened by habitat loss and hunting, the species is assessed as endangered by the IUCN.
The blue korhaan or blue bustard is a species of bird in the family Otididae which is native to South Africa. Its call is a series of frog-like croaks, usually uttered in flight. Its natural habitat is plateau grassland, dry shrubland, arable land and pastureland. Its preferred habitat is one with short grassland and flat topography.
The bushy-crested jay is a species of bird in the family Corvidae. It is found in Central America, where its natural habitats are subtropical or tropical moist montane forests and heavily degraded former forest. There are two subspecies, C. m. melanocyaneus which is found in Guatemala and southern El Salvador, and C. m. chavezi from Honduras and northeastern Nicaragua.
The Yucatan jay is a species of bird in the family Corvidae, the crows and their allies. It is native to the Yucatán Peninsula where its habitats are subtropical or tropical dry forest, plantations and cleared areas at altitudes up to 250 m (820 ft). Adults are about 30 cm (12 in) long, black, with blue wings, mantle, and tail, black bills, yellow eye rings and legs. Immature birds have yellow bills. This is a common species of jay with a wide range and the International Union for Conservation of Nature has rated its conservation status as being of "least concern".
The silvery-throated jay is a species of bird in the family Corvidae. It is found in the Talamancan montane forests of Costa Rica and western Panama. The IUCN has rated its conservation status as being of "least concern".
The Mongolian ground jay or Henderson's ground jay, is a species of bird in the family Corvidae.
The Turkestan ground jay, grey ground jay or Pander's ground-jay is a species of bird in the crow and jay family, Corvidae. It is found in central Asia, particularly Kazakhstan, Turkmenistan, and Uzbekistan. More specifically, they tend to be found in Astragalus, Calligonum and southern Salsola vegetation zones. It is closely related to the Iranian ground jay. Its natural habitat is sandy desert with low shrub cover. It also forages around human settlements and roads.
The Iranian ground jay or Pleske's ground jay, is a species of bird in the family Corvidae. It is endemic to Iran where it is known as Zaqboor in Farsi.
