The Amami woodpecker (Dendrocopos leucotos owstoni) is a bird in the family Picidae found only on Amami Ōshima in the Ryukyu Islands south of Japan. The species is confined to mature evergreen broadleaf forest in the hills of the island. It specialises in eating large wood-boring insects. It is usually considered conspecific with the white-backed woodpecker (Dendrocopos leucotos). The Amami woodpecker is still considered as a subspecies of the white-backed woodpecker in the list maintained by the International Ornithologists' Union and the Clements Checklist.

Dendrocopos is a widespread genus of woodpeckers from Asia and Europe and Northern Africa. The species range from the Philippines to the British Isles.
The genus was introduced by the German naturalist Carl Ludwig Koch in 1816. The name Dendrocopus is a combination of the Greek words dendron , meaning "tree" and kopos, "striking ". The type species was specified as the great spotted woodpecker (Dendrocopos major) by the Scottish ornithologist Edward Hargitt in 1890 in his catalogue of woodpeckers in the collection of the British Museum.The genus Dendrocopos at one time contained around 25 species. A molecular phylogenetic analysis of the pied woodpeckers published in 2015 found that Dendrocopos was polyphyletic. In the rearranged genera the number of species in Dendrocopos was reduced to 12 (or 13) as listed below.List of birds of Asia
The birds of Asia are diverse.
The taxonomy of this list adheres to James Clements' Birds of the World: A Checklist, 6th edition. Taxonomic changes are on-going. As more research is gathered from studies of distribution, behaviour, and DNA, the order and number of families and species may change. Furthermore, different approaches to ornithological nomenclature have led to concurrent systems of classification (see Sibley-Ahlquist taxonomy).
The area covered by this list corresponds with the Asian listing area as defined by the American Birding Association. The area includes Russia east of the Ural River and Ural Mountains and the Russian Arctic islands east of but not including Novaya Zemlya, as well as Kazakhstan, Georgia, Azerbaijan, Turkey (except for the portion north of the Bosporus, Sea of Marmara and the Dardanelles) and Cyprus. The area is separated from Africa by the Suez Canal. In the Indian Ocean it includes Sri Lanka, Lakshadweep (the Laccadive Islands), the Andaman and Nicobar Islands, but does not include Socotra (Africa), the Maldives, the Chagos Archipelago and Christmas Island (all Indian Ocean). It includes the Russian islands in the Bering Sea and North Pacific. Japan, the Izu Islands (except Nampo Shoto and the Daitō Islands), the Ryukyu Islands, Taiwan, the Philippines, Malaysia and most of Indonesia. In Indonesia, the dividing line between Asia and Australasia runs through the Banda and Molucca Seas with Sulawesi, Banggai and Talaud on the Asian side, and the islands of Kai, Ceram, Buru, the Sula Group and Morotai on the Australasian side.List of birds of Japan
This is a list of the bird species recorded in Japan. The avifauna of Japan include a total of 722 species, of which 16 are endemic, and 39 have been introduced by humans.
This list's taxonomic treatment (designation and sequence of orders, families and species) and nomenclature (common and scientific names) follow the conventions of The Clements Checklist of Birds of the World, 2018 edition.The following tags highlight several categories of occurrence other than regular migrants and non-endemic residents.
(A) Accidental – a species that rarely or accidentally occurs in Japan (also called a vagrant)
(E) Endemic – a species endemic to Japan
(I) Introduced – a species introduced to Japan as a consequence, direct or indirect, of human actionsList of near threatened birds
As of May 2019, the International Union for Conservation of Nature (IUCN) lists 1012 near threatened avian species. 9.3% of all evaluated avian species are listed as near threatened.
No subpopulations of birds have been evaluated by the IUCN.
This is a complete list of near threatened avian species evaluated by the IUCN. Where possible common names for taxa are given while links point to the scientific name used by the IUCN.Picinae
Woodpeckers are near passerine birds of the order Piciformes. They are one subfamily in the family Picidae, which also includes the piculets and wrynecks. They are found worldwide.
Woodpeckers gained their English name because of the habit of some species of tapping and pecking noisily on tree trunks with their beaks and heads. This is both a means of communication to signal possession of territory to their rivals, and a method of locating and accessing insect larvae found under the bark or in long winding tunnels in the tree or upright log.Ryukyu Islands
The Ryukyu Islands (琉球諸島, Ryūkyū-shotō), also known as the Nansei Islands (南西諸島, Nansei-shotō, lit. "Southwest Islands") or the Ryukyu Arc (琉球弧, Ryūkyū-ko), are a chain of Japanese islands that stretch southwest from Kyushu to Taiwan: the Ōsumi, Tokara, Amami, Okinawa, and Sakishima Islands (further divided into the Miyako and Yaeyama Islands), with Yonaguni the westernmost. The larger are mostly high islands and the smaller mostly coral. The largest is Okinawa Island.
The climate of the islands ranges from humid subtropical climate (Köppen climate classification Cfa) in the north to tropical rainforest climate (Köppen climate classification Af) in the south. Precipitation is very high and is affected by the rainy season and typhoons. Except the outlying Daitō Islands, the island chain has two major geologic boundaries, the Tokara Strait (between the Tokara and Amami Islands) and the Kerama Gap (between the Okinawa and Miyako Islands). The islands beyond the Tokara Strait are characterized by their coral reefs.
The Ōsumi and Tokara Islands, the northernmost of the islands, fall under the cultural sphere of the Kyushu region of Japan; the people are ethnically Japanese and speak a variation of the Kagoshima dialect of Japanese. The Amami, Okinawa, Miyako, and Yaeyama Islands have a native population collectively called the Ryukyuan people, named for the former Ryukyu Kingdom that ruled them. The varied Ryukyuan languages are traditionally spoken on these islands, and the major islands have their own distinct languages. In modern times, the Japanese language is the primary language of the islands, with the Okinawan Japanese dialect prevalently spoken. The outlying Daitō Islands were uninhabited until the Meiji period, when their development was started mainly by people from the Izu Islands south of Tokyo, with the people there speaking the Hachijō language.
Administratively, the islands are divided into Kagoshima Prefecture (specifically the islands administered by Kagoshima District, Kumage Subprefecture/District, and Ōshima Subprefecture/District) in the north and Okinawa Prefecture in the south, with the divide between the Amami and Okinawa Islands, with the Daitō Islands part of Okinawa Prefecture. The northern (Kagoshima) islands are collectively called the Satsunan Islands, while the southern part of the chain (Okinawa Prefecture) are called the Ryukyu Islands in Chinese.
