Poliolimnas cinereus brevipes Ingram, 1911 |
The Iwo Jima rail or white-browed crake (Poliolimnas cinereus brevipes) [1] was a rail native to the island of Iwo Jima. The last reported sightings were in 1924, and the species is believed to be extinct. It was a subspecies of the white-browed crake.
The Iwo Jima rail was coloured dark brown, with black mottles on its back, and a white colouration on its belly. The bird was typically about six inches long. [2]
The species cinereus was typically found in both brackish water and fresh water marshes. Iwo Jima, however, lacked these features, and the Iwo Jima subspecies lived in the brush and tall grass along rivulets on the island, as well as damp places within the original forest cover. [3]
When humans settled the island of Iwo Jima, they cleared away the existing forest to grow sugarcane. The forest clearance reduced the availability of fresh water, which forced the bird to come into the settlements to find water during the dry season. Here the birds often fell pray to cats. Combined with the introduction of rats to the island, this caused the extinction of the bird. [2]
The last specimen of the bird was collected in 1911, and the last reported sightings were by T. T. Moniyama in 1924. [2]
Iwo Jima, known in Japan as Iō Tō, is one of the Japanese Volcano Islands and lies south of the Bonin Islands. Together with other islands, they form the Ogasawara Archipelago. The highest point of Iwo Jima is Mount Suribachi at 169 m (554 ft) high.
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.
The Bonin Islands, also known as the Ogasawara Islands, or, Yslas del Arzobispo, are an archipelago of over 30 subtropical and tropical islands, some 1,000 kilometres directly south of Tokyo, Japan. The name "Bonin Islands" comes from the Japanese word bunin, meaning "no people" or "uninhabited". The only inhabited islands of the group are Chichijima (父島), the seat of the municipal government, and Hahajima (母島).
The Volcano Islands or Iwo Islands are a group of three Japanese islands south of the Ogasawara Islands that belong to the municipality of Ogasawara, Tokyo Metropolis, Japan. The islands are all active volcanoes lying atop an island arc that stretches south to the Marianas. They have an area of 32.55 square kilometres (12.57 sq mi), and a population of 380. The island of Iwo Jima in the Volcano Islands lies about 1,240 kilometres (770 mi) southeast of Miyazaki.
Flightless birds are birds that through evolution lost the ability to fly. There are over 60 extant species, including the well known ratites and penguins. The smallest flightless bird is the Inaccessible Island rail. The largest flightless bird, which is also the largest living bird, is the ostrich. Ostriches are farmed for their decorative feathers, meat and their skins, which are used to make leather.
The Ogasawara subtropical moist forests is a terrestrial ecoregion which encompasses the Ogasawara Archipelago of Japan. The Ogasawara Archipelago lies in the Pacific Ocean south of Honshu, Japan's largest island, and north of the Marianas Islands. The ecoregion includes the Bonin Islands and Volcano Islands chains. The islands are volcanic in origin, and have never been linked to a continent. They are home to distinct plants and animals including many endemic species.
The warbling white-eye, also known as the Japanese white-eye and mountain white-eye, is a small passerine bird in the white-eye family. The specific epithet is occasionally written japonica, but this is incorrect due to the gender of the genus. Its native range includes much of East Asia, including the Russian Far East, Japan, Indonesia, Korea, and the Philippines. It has been intentionally introduced to other parts of the world as a pet and as pest control, with mixed results. As one of the native species of the Japanese islands, it has been depicted in Japanese art on numerous occasions, and historically was kept as a cage bird.
The Okinawa rail is a species of bird in the rail family, Rallidae. It is endemic to Okinawa Island in Japan where it is known as the Yanbaru kuina. 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.
The white-browed crake is a species of bird in the family Rallidae. It is found in Australia, Brunei, Cambodia, Fiji, Hong Kong, Indonesia, Japan, India, Malaysia, Micronesia, New Caledonia, Palau, Papua New Guinea, the Philippines, Samoa, Singapore, Solomon Islands, Thailand, and Vanuatu.
The Bonin flying fox, Bonin fruit bat, or in Japanese Ogasawara giant bat is a species of flying fox in the family Pteropodidae. It is endemic to four islands in Ogasawara Islands, Japan. Its natural habitat is subtropical forests. It is threatened by habitat loss.
The Lord Howe pigeon, Columba vitiensis godmanae, was a subspecies of the metallic pigeon which existed on Lord Howe Island. It became extinct in the 1850s.
The South Island kōkako is a possibly extinct forest bird endemic to the South Island of New Zealand. Unlike its close relative the North Island kōkako it has largely orange wattles, with only a small patch of blue at the base, and was also known as the orange-wattled crow. The last accepted sighting in 2007 was the first considered genuine since 1967, although there have been several other unauthenticated reports.
