Gallirallus
''Gallirallus'' is a genus of rails that live in the Australasian-Pacific region. The genus is characterised by an ability to colonise relatively small and isolated islands and thereafter to evolve flightless forms, many of which became extinct following Polynesian settlement. Taxonomy Following recent taxonomic revisions, there is only one known extant species in this genus along with several extinct species of dubious classification, with all other species being moved to ''Hypotaenidia'', ''Cabalus'', or '' Aptenorallus''. Description Many of the rails, including the well-known weka of New Zealand, are flightless or nearly so. Many of the resultant flightless island endemics became extinct after the arrival of humans, which hunted these birds for food, introduced novel predators like rats, dogs or pigs, and upset the local ecosystems. A common Polynesian name of these rails, mainly relatives of ''G. philippensis'', is ''veka''/''weka'' (in English, this name is generally l ...

Weka
The weka, also known as the Māori hen or woodhen (''Gallirallus australis'') is a flightless bird species of the rail family. It is endemic to New Zealand. It is the only extant member of the genus ''Gallirallus''. Four subspecies are recognized but only two (northern/southern) are supported by genetic evidence. The weka are sturdy brown birds, about the size of a chicken. As omnivores, they feed mainly on invertebrates and fruit. Weka usually lay eggs between August and January; both sexes help to incubate. Description Weka are large rails. They are predominantly rich brown mottled with black and grey; the brown shade varies from pale to dark depending on subspecies. The male is the larger sex at in length and in weight. Females measure in length and weigh . The reduced wingspan ranges from . The relatively large, reddish-brown beak is about long, stout and tapered, and used as a weapon. The pointed tail is near-constantly being flicked, a sign of unease characteristic of ...

Calayan Rail
The Calayan rail (''Aptenorallus calayanensis'') is a flightless bird of the rail, moorhen, and coot family (Rallidae) that inhabits Calayan Island in the Philippines. It is the only member of the genus ''Aptenorallus''. Though well known to natives of the island as the "piding", it was first observed by ornithologist Carmela Española in May 2004 and the discovery was officially announced on August 16, 2004. The formal description as a species new to science appeared in the journal Forktail (Allen ''et al.'' 2004). Taxonomy Prior to 2022, it was classified in the genus ''Gallirallus''. Following studies in 2012 and 2013, all recent species in the genus ''Gallirallus'' aside from the Calayan rail and the weka of New Zealand were moved to the genus ''Hypotaenidia''. Following this, the Calayan rail and the weka were considered the two extant species of the genus ''Gallirallus''. However, a 2021 phylogenetic study found the Calayan rail to be basal to the species classified in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rallidae
The rails, or Rallidae, are a large cosmopolitan family of small- to medium-sized, ground-living birds. The family exhibits considerable diversity and includes the crakes, coots, and gallinules. Many species are associated with wetlands, although the family is found in every terrestrial habitat except dry deserts, polar regions, and alpine areas above the snow line. Members of the Rallidae occur on every continent except Antarctica. Numerous island species are known. The most common rail habitats are marshland and dense forest. They are especially fond of dense vegetation.Horsfall & Robinson (2003): pp. 206–207 Name "Rail" is the anglicized respelling of the French ''râle'', from Old French ''rasle''. It is named from its harsh cry, in Vulgar Latin *''rascula'', from Latin ''rādere'' ("to scrape"). Morphology The rails are a family of small to medium-sized, ground-living birds. They vary in length from and in weight from . Some species have long necks and in many ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Okinawa Rail
The Okinawa rail (''Hypotaenidia okinawae'') is a species of bird in the rail family, Rallidae. It is endemic to Okinawa Island in Japan where it is known as the . Its existence was only confirmed in 1978 and it was formally described in 1981 although unidentified rails had been recorded on the island since at least 1973 and local stories of a bird known as the ''agachi kumira'' may refer to this species.Brazil, Mark A. (1991) ''The Birds of Japan'', Christopher Helm, London. It is a medium-sized and almost flightless rail with short wings and tail, olive-brown upperparts, black underparts with white bars and a red bill and legs. It occurs in subtropical moist forests and in neighboring habitats. It nests and feeds on the ground but usually roosts in trees. It is classified as an endangered species and is threatened by habitat loss and introduced predators. Taxonomy The species was first described in 1981 by Yoshimaro Yamashina and T. Mano in the ''Journal of the Yamashina ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Guam Rail
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. Backgrou ...

Lord Howe Woodhen
The Lord Howe woodhen (''Hypotaenidia sylvestris'') also known as the Lord Howe Island woodhen or Lord Howe (Island) rail, is a flightless bird of the rail family, (Rallidae). It is endemic to Lord Howe Island off the Australian coast. It is currently classified as endangered by the IUCN. Description The Lord Howe woodhen is a small olive brown bird, with a short tail and a downcurved bill. Wings are chestnut with darker bars. The eyes have a red iris. Ecology The species lives in sub-tropical forests, feeding on earthworms, crustaceans, fruit, and occasionally taking the eggs of shearwaters and petrels. Woodhens mate for life and are usually encountered in pairs. They are territorial and will appear from the forest's understory to investigate the source of any unusual noise. A mated pair will defend an area of approximately three hectares, with offspring being expelled from this area once grown. The population of birds is thus restricted by the amount of available territory. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
