New Caledonian Rail
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 sm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bird
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. B ...

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] |
Chatham Rail
The Chatham rail (''Cabalus modestus'') is an extinct flightless species of bird in the family Rallidae. It was endemic to Chatham, Mangere and Pitt Islands, in the Chatham archipelago of New Zealand. The Chatham rail and the Dieffenbach's rail, both flightless, were sympatric on the Chatham Islands. Their sympatry suggests parallel evolution after separate colonisation of the Chatham Islands by a common volant ancestor. A genetic analysis from 1997 suggested that the two were sister taxa. However more recent genetic analysis finds them to not be closely related within the ''Gallirallus'' radition, with a 2014 analysis finding the Chatham rail being sister taxon to the New Caledonian rail instead. The Chatham rail was first discovered on Mangere in 1871, and 26 specimens collected there are known from museum collections. It became extinct on the island between 1896 and 1900. The species is also known from 19th century bones from Chatham and Pitt Islands. It is likely to ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
