List Of Critically Endangered Birds
As of December 2019, the International Union for Conservation of Nature (IUCN) listed 224 critically endangered avian species, including 19 which are tagged as possibly extinct or possibly extinct in the wild. 2% of all evaluated avian species are listed as critically endangered. No subpopulations of birds have been evaluated by the IUCN. Additionally 55 avian species (0.48% of those evaluated) are listed as data deficient, meaning there is insufficient information for a full assessment of conservation status. As these species typically have small distributions and/or populations, they are intrinsically likely to be threatened, according to the IUCN. While the category of data deficient indicates that no assessment of extinction risk has been made for the taxa, the IUCN notes that it may be appropriate to give them "the same degree of attention as threatened taxa, at least until their status can be assessed".

Puffinus Auricularis
Townsend's shearwater (''Puffinus auricularis'') is a rare seabird of the tropics from the family Procellariidae. Taxonomy Its relationships are unresolved. Its closest relatives are probably, but not certainly, the Hawaiian shearwater (''Puffinus newelli'') and possibly the Manx shearwater (''Puffinus puffinus'') (Austin, 1996; Austin ''et al.'', 2004). It formerly contained the former as a subspecies and was long considered a subspecies of the latter. The relationship of the Rapa shearwater, ''P. myrtae'' in regard to these species are also in need of research; this taxon was until recently placed in '' P. assimilis'' (Austin ''et al.'', 2004), but now raised to full species status by the IOC and the NACC of the AOU. Conservation This species breeds around Cerro Evermann on Isla Socorro in the Revillagigedo Islands, Mexico, though formerly present on Clarion Island and San Benedicto San Benedicto, formerly Isla de los Innocentes, is an uninhabited island, and third l ...

Parrots
Parrots, also known as psittacines (), are birds of the roughly 398 species in 92 genus (biology), genera comprising the order (biology), order Psittaciformes (), found mostly in tropics, tropical and subtropics, subtropical regions. The order is subdivided into three superfamilies: the true parrot, Psittacoidea ("true" parrots), the Cockatoo, Cacatuoidea (cockatoos), and the New Zealand parrot, Strigopoidea (New Zealand parrots). One-third of all parrot species are threatened by extinction, with higher aggregate extinction risk (Red List Index, IUCN Red List Index) than any other comparable bird group. Parrots have a generally pantropical distribution with several species inhabiting temperateness, temperate regions in the Southern Hemisphere, as well. The greatest biodiversity, diversity of parrots is in South America and Australasia. Characteristic features of parrots include a strong, curved beak, bill, an upright stance, strong legs, and clawed Dactyly#In birds, zygodactyl f ...

Sarothrura Ayresi
The white-winged flufftail (''Sarothrura ayresi'') is a very rare African bird in the family Sarothruridae. The estimated global population size of white-winged flufftails is less than 250 adults. These birds reside in Ethiopia and South Africa but it is unknown whether these populations are one large or two different populations. Both sexes have dull plumage, dark crowns, and when flying show white secondary feathers. Their habitat consists of high altitude seasonal marshland with high sedge cover to protect their ground nests. Habitat loss is the main problem facing these birds as they require highly specialized habitat. These marshlands are being destroyed for a number of reasons such as, farming, grazing and sedge harvesting, but some efforts are being taken to protect the white-winged flufftail. Description Its scientific name honours South African ornithologist Thomas Ayres, who discovered it at Potchefstroom.The once extensive Potchefstroom marshes have since been ...

Gallinula Silvestris
The Makira woodhen (''Gallinula silvestris''), also known as the Makira moorhen, is a species of bird in the family Rallidae. It is endemic to the Solomon Islands. Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical moist montane forest. It is critically endangered and sometimes considered extinct from habitat loss and predation by feral cats A feral cat or a stray cat is an unowned domestic cat (''Felis catus'') that lives outdoors and avoids human contact: it does not allow itself to be handled or touched, and usually remains hidden from humans. Feral cats may breed over dozens .... The last recorded sighting was in 1953. References External linksBirdLife Species Factsheet.

Gallinula Pacifica
The Samoan woodhen (''Gallinula pacifica''), also known as Samoan wood rail, is a nearly flightless rail endemic to the Samoan island of Savai'i that has been considered Critically Endangered, and possibly extinct. As it has evolved adaptations for a more terrestrial lifestyle and at least partly nocturnal habits, it is probably better placed in a distinct genus, ''Pareudiastes'' (which sometimes includes the more distinct Makira wood rail too), but this issue has not yet been thoroughly researched. It was known as ''puna'e'' ("one that jumps up") to the native Samoans; this was said to relate to the bird's habit of making a jumping dash into cover when startled from its resting place. Description This small gallinule had a length of about 25 cm. The plumage was darkish blue on head, neck and breast contrasted with an entirely black rump and tail. The upperparts were dark olivaceous with a greenish sheen. The bill and the frontal shield were yellowish to orange red. The ...

Leucogeranus Leucogeranus
The Siberian crane (''Leucogeranus leucogeranus''), also known as the Siberian white crane or the snow crane, is a bird of the family Gruidae, the cranes. They are distinctive among the cranes: adults are nearly all snowy white, except for their black primary feathers that are visible in flight, and with two breeding populations in the Arctic tundra of western and eastern Russia. The eastern populations migrate during winter to China, while the western population winters in Iran and (formerly) in Bharatpur, India. Among the cranes, they make the longest distance migrations. Their populations, particularly those in the western range, have declined drastically in the 20th century due to hunting along their migration routes and habitat degradation. The world population was estimated in 2010 at about 3,200 birds, mostly belonging to the eastern population with about 95% of them wintering in the Poyang Lake basin in China, a habitat that may be altered by the Three Gorges Dam.

Hypotaenidia Owstoni
The Guam rail (''Hypotaenidia owstoni'') is a species of flightless bird, endemic to the United States territory of Guam, where it is known locally as the ''Ko'ko bird. The Guam rail disappeared from southern Guam in the early 1970s and was extirpated from the entire island by the late 1980s. This species is now being bred in captivity by the Division of Aquatic and Wildlife Resources on Guam and at some mainland U.S. zoos. Since 1995, more than 100 rails have been introduced on the island of Rota in the Commonwealth of the Northern Mariana Islands in an attempt to establish a wild breeding colony. Although at least one chick resulted from these efforts, feral cat predation and accidental deaths have been extremely high. In 2010, 16 birds were released onto Cocos Island, with 12 more being introduced in 2012. In 2019, the species became only the second bird after the California condor to be reclassified by the IUCN from extinct in the wild to critically endangered. ...

Gallirallus Lafresnayanus
The New Caledonian rail (''Cabalus lafresnayanus'') is a large and drab flightless rail that is found on the island of New Caledonia in the Pacific. It is a dull brown above, with grey underparts, and has a yellowish, downward-curving bill. No one knows what it sounds like and it is not known whether it is nocturnal or crepuscular. It most likely was driven to extinction from predation by feral cats, dogs, and pigs. Status This cryptic rail is only known from seventeen specimens taken between 1860 and 1890 on New Caledonia. This bird is supposed to live in evergreen forests and seems to have moved higher up on the island to escape introduced predators. Its diet consists of invertebrates, including earthworms. Though the bird has not been confirmed since 1890, unconfirmed reports from the 1960s and 1984 say that some still live in the higher montane forests. A survey in 1998 produced no firm evidence from hunters or fieldwork. However, many still believe it persists in small ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyanolimnas Cerverai
The Zapata rail (''Cyanolimnas cerverai'') is a medium-sized, dark-coloured rail, the only member of the monotypic genus ''Cyanolimnas''. It has brown upperparts, greyish-blue underparts, a red-based yellow bill, white undertail coverts, and red eyes and legs. Its short wings render it almost flightless. It is endemic to the wetlands of the Zapata Peninsula in southern Cuba, where its only known nest was found in sawgrass tussocks. Little is known of its diet or reproductive behaviour, and its described calls may belong to a different species. The species was discovered by Spanish zoologist Fermín Zanón Cervera in March 1927 in the Zapata Swamp near Santo Tomás, in the southern Matanzas Province of Cuba. The swamp holds one other bird found nowhere else, the Zapata wren, and also gives its name to the Zapata sparrow. Due to ongoing habitat loss in its limited range, its small population size, and predation by introduced mammals and catfish, the Zapata rail is ...

Gruiformes
The Gruiformes are an order (biology), order containing a considerable number of living and extinct bird family (biology), families, with a widespread geographical diversity. Gruiform means "crane-like". Traditionally, a number of wading and terrestrial bird families that did not seem to belong to any other order were classified together as Gruiformes. These include 14 species of large crane (bird), cranes, about 145 species of smaller Rallidae, crakes and rails, as well as a variety of families comprising one to three species, such as the Heliornithidae, the limpkin, or the Psophiidae. Other birds have been placed in this order more out of necessity to place them ''somewhere''; this has caused the expanded Gruiformes to lack distinctive apomorphies. Recent studies indicate that these "odd Gruiformes" are if at all only loosely related to the cranes, rails, and relatives ("core Gruiformes"). Systematics There are only two suprafamilial clades (natural groups) among the birds t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Puffinus Mauretanicus
The Balearic shearwater (''Puffinus mauretanicus'') is a medium-sized shearwater in the seabird family ''Procellariidae''. ''Puffinus'' is a New Latin loanword based on the English "puffin" and its variants, that referred to the cured carcass of the fat nestling of the Manx shearwater, a former delicacy. The specific ''mauretanicus'' refers to Mauretania, an old name for an area of North Africa roughly corresponding to Morocco and Algeria. Taxonomy The Balearic shearwater was formerly described in 1921 by the English ornithologist Percy Lowe. He treated it as a subspecies of the Manx shearwater and coined the trinomial name ''Puffinus puffinus mauretanicus''. The Balearic shearwater was long regarded a subspecies of the Manx shearwater. Following an initial split, it was held to be a subspecies of the "Mediterranean shearwater" for nearly ten more years, until it was resolved to be a distinct species, separate from the yelkouan shearwater. It is the last taxon of the ''Puffi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
