The white-eyes are a family, Zosteropidae, of small passerine birds native to tropical, subtropical and temperate Sub-Saharan Africa, southern and eastern Asia, and Australasia. White-eyes inhabit most tropical islands in the Indian Ocean, the western Pacific Ocean, and the Gulf of Guinea. Discounting some widespread members of the genus Zosterops, most species are endemic to single islands or archipelagos. The silvereye, Zosterops lateralis, naturally colonised New Zealand, where it is known as the "wax-eye" or tauhou ("stranger"), from 1855. The silvereye has also been introduced to the Society Islands in French Polynesia, while the Japanese white-eye has been introduced to Hawaii.
The Ogasawara Islands, also known as the Bonin Islands, are a Japanese archipelago of over 30 subtropical and tropical islands located around 1,000 kilometers (620 mi) SSE of Tokyo and 1,600 kilometers (1,000 mi) northwest of Guam. The group as a whole has a total area of 84 square kilometers (32 sq mi) but only two of the islands are permanently inhabited, Chichijima and Hahajima. Together, their population was 2560 as of 2021. Administratively, Tokyo's Ogasawara Subprefecture also includes the settlements on the Volcano Islands and the Self-Defense Force post on Iwo Jima. The seat of government is Chichijima.
Hahajima, Haha Jima, or Haha-jima is the second-largest island within the Bonin or Ogasawara Islands SSE of the Japanese Home Islands. The steeply-sloped island, which is about 21 km2 (8 sq mi) in area, has a population of 440. It is part of Ogasawara Village in Ogasawara Subprefecture, which is approximately 1,000 km (620 mi) south of Tokyo, Japan.
Endemism is the state of being a species found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be endemic to that particular part of the world. An endemic species can also be referred to as an endemism or in scientific literature as an endemite.
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.
This article is one of a series providing information about endemism among birds in the world's various zoogeographic zones. For an overview of this subject see Endemism in birds.
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 Bonin grosbeak or Bonin Islands grosbeak is an extinct finch. It is one of the diverse bird taxa that are vernacularly called "grosbeaks", but it is not closely related to the grosbeaks sensu stricto. Many authorities place the species in the genus Carpodacus, but some place it in its own genus, Chaunoproctus. A 2013 genetic analysis found it to be a relatively basal member of the group, more derived than the common rosefinch, but with no close relatives, with an estimated divergence time from other members of the group around 12.5 million years ago.
The Bonin white-eye or meguro (メグロ) is a small songbird endemic to the Bonin Islands of Japan. It is the only species in the genus Apalopteron. Its taxonomic affinities were a long-standing mystery and it has been placed with the bulbuls, babblers and more recently with the honeyeaters, during which it was known as the Bonin honeyeater. Since 1995 it is known to be a white-eye in the family Zosteropidae, that is closely related to the golden white-eye of the Marianas Islands.
The wildlife of Japan includes its flora, fauna, and natural habitats. The islands of Japan stretch a long distance from north to south and cover a wide range of climatic zones. This results in a high diversity of wildlife despite Japan's isolation from the mainland of Asia. In the north of the country, north of Blakiston's Line, there are many subarctic species which have colonized Japan from the north. In the south there are south-east Asian species, typical of tropical regions. Between these areas lies the temperate zone which shares many species with China and Korea. Japan also has many endemic species that are found nowhere else in the world, making it home to many endangered/rare species.
The black wood pigeon or Japanese wood pigeon is a species of bird in the family Columbidae. It is found in East Asia along shorelines of the Pacific's Korea Strait, Philippine Sea and East China Sea. It is believed to be the largest representative of the genus, Columba, and has a weight of around 550 grams (1.2 lb) and an overall length of 43 cm (17 in). Its natural habitats are temperate forests and subtropical or tropical moist lowland forests. The species is in decline owing to habitat loss, habitat degradation, deforestation and hunting. This wood pigeon is endemic to the laurel forest habitat.
Ogasawara Subprefecture is a subprefecture of the Tokyo Metropolitan Government in Japan. The subprefecture covers the Bonin and Volcano Islands and three isolated islets and is coterminous with the village of Ogasawara. The subprefecture covers 104.41 square kilometers (40.31 sq mi) and has a population of 2,415 people. It maintains a main office on Chichijima and a branch office on Hahajima, the two permanent settlements in the islands.
Along with a number of other organisms, the Japanese white-eye has become an invasive species in Hawaii. Its native range includes much of East Asia, including Japan, China, Vietnam, Taiwan, and the Philippines.
The Carolines tropical moist forests is a tropical and subtropical moist broadleaf forests ecoregion in Micronesia. It includes the central and eastern Caroline Islands in the Federated States of Micronesia.
The Bonin greenfinch, also known as the Ogasawara greenfinch, is a small passerine bird in the finch family Fringillidae that is endemic to the Ogasawara Islands of Japan, where it is found on the Bonin Islands and Volcano Islands. It was formerly considered a subspecies of the grey-capped greenfinch and some authorities consider it as such, but a 2020 analysis found it likely to represent a distinct species that diverged from C. sinica about 1.06 million years ago, and the International Ornithological Congress now recognizes it as such, making it the eleventh endemic species in Japan. There are fewer than 400 individuals in the population and it is considered critically endangered by the Japanese government, necessitating protection. According to the Yamashina Institute for Ornithology, as of December 2021, the Ogaswara greenfinch is Japan's most endangered bird.
The Bonin Islands are an archipelago of over 30 subtropical and tropical islands, some 1,000 kilometres directly south of Tokyo, Japan and 1,000 miles northwest of Guam.
