Ryukyu Kingfisher
The Ryukyu kingfisher (''Todiramphus cinnamominus miyakoensis'') is an enigmatic taxon of tree kingfisher. It is extinct and is only known from a single specimen. Its taxonomic status is doubtful; it is most likely a subspecies of the Guam kingfisher, which would make its scientific name ''Todiramphus cinnamominus miyakoensis''. As the specimen is at the Yamashina Institute for Ornithology, the question could be resolved using DNA sequence analysis; at any rate, the Guam kingfisher is almost certainly the closest relative of the Ryukyu bird. The IUCN considers this bird a subspecies and has hence struck it from its redlist. The one known bird, probably a male, was according to its label collected on Miyako-jima, the main island of the Miyako group, Ryūkyū Shotō, on February 5, 1887. While it is often and correctly stated that specimen labels may be incorrect or misleading, the locality, to the northwest of the extant populations of ''Todiramphus cinnamominus'', seems so ...

Nagamichi Kuroda
was a Japanese ornithologist. His works included ''Birds of the Island of Java'' (2 Volumes, 1933–36) and ''Parrots of the World in Life Colours'' (1975). He described the crested shelduck in 1917. He also worked on the distinction between the auks and petrels and the special characteristics of shearwaters that foraged underwater.Kuroda, N. 1953.

Ryukyu Islands
The , also known as the or the , 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 un ...

Birds Of The Ryukyu Islands
Birds are a group of warm-blooded vertebrates constituting the class (biology), class Aves (), characterised by feathers, toothless beaked jaws, the Oviparity, laying of Eggshell, hard-shelled eggs, a high Metabolism, metabolic rate, a four-chambered heart, and a strong yet lightweight Bird skeleton, skeleton. Birds live worldwide and range in size from the bee hummingbird to the Common ostrich, 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 Flightless bird, loss of flight in some birds, including ratites, penguins, and diverse endemism, endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extinct Animals Of Japan
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dodos, m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Controversial Bird Taxa
Controversy is a state of prolonged public dispute or debate, usually concerning a matter of conflicting opinion or point of view. The word was coined from the Latin ''controversia'', as a composite of ''controversus'' – "turned in an opposite direction". Legal In the theory of law, a controversy differs from a legal case; while legal cases include all suits, criminal as well as civil, a controversy is a purely civil proceeding. For example, the Case or Controversy Clause of Article Three of the United States Constitution ( Section 2, Clause 1) states that "the judicial Power shall extend ... to Controversies to which the United States shall be a Party". This clause has been deemed to impose a requirement that United States federal courts are not permitted to cases that do not pose an actual controversy—that is, an actual dispute between adverse parties which is capable of being resolved by the ourt In addition to setting out the scope of the jurisdiction of ...

Todiramphus
''Todiramphus'' is a genus of kingfishers in the subfamily Halcyoninae. The genus was introduced by the French surgeon and naturalist René Lesson in 1827. The name is often spelt ''Todirhamphus'' (with ''rh''), but ''Todiramphus'' is the original valid spelling. The name literally means "tody-bill"; tody is a relative of the kingfishers with a similar slender long bill, and the Greek ' () means "beak" or "bill". There are around 30 extant species in the genus, but the classification of several Pacific island forms is still unclear. The range of the genus extends from the Red Sea in the west to French Polynesia in the east, with the greatest diversity in Australasia. Members of ''Todiramphus'' are medium-sized kingfishers with flattened beaks. They are typically blue or blue-green above with pale underparts. They often have a pale collar and stripe over the eye. Many species are commonly found well away from water and feed largely on terrestrial animals such as insects and liza ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Remiges
Flight feathers (''Pennae volatus'') are the long, stiff, asymmetrically shaped, but symmetrically paired pennaceous feathers on the wings or tail of a bird; those on the wings are called remiges (), singular remex (), while those on the tail are called rectrices (), singular rectrix (). The primary function of the flight feathers is to aid in the generation of both thrust and lift, thereby enabling flight. The flight feathers of some birds have evolved to perform additional functions, generally associated with territorial displays, courtship rituals or feeding methods. In some species, these feathers have developed into long showy plumes used in visual courtship displays, while in others they create a sound during display flights. Tiny serrations on the leading edge of their remiges help owls to fly silently (and therefore hunt more successfully), while the extra-stiff rectrices of woodpeckers help them to brace against tree trunks as they hammer on them. Even flightless birds ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biogeography
Biogeography is the study of the distribution of species and ecosystems in geographic space and through geological time. Organisms and biological communities often vary in a regular fashion along geographic gradients of latitude, elevation, isolation and habitat area.Brown University, "Biogeography." Accessed February 24, 2014. . Phytogeography is the branch of biogeography that studies the distribution of plants. Zoogeography is the branch that studies distribution of animals. Mycogeography is the branch that studies distribution of fungi, such as mushrooms. Knowledge of spatial variation in the numbers and types of organisms is as vital to us today as it was to our early human ancestors, as we adapt to heterogeneous but geographically predictable environments. Biogeography is an integrative field of inquiry that unites concepts and information from ecology, evolutionary biology, taxonomy, geology, physical geography, palaeontology, and climatology.Dansereau, Pierre. 1957 ...

Miyako Islands
The (also Miyako Jima group) are a group of islands in Okinawa Prefecture, Japan, belonging to the Ryukyu Islands. They are situated between the Okinawa Island and Yaeyama Islands. In the early 1870s, the population of the islands was estimated to number approximately 10,000. Miyako island has 55,914 people. A bridge connects Miyako Island to Ikema Island, which has 801 people. Tarama village has 1,214 people, between the two islands of Minna and Tarama. Important Bird Area The islands have been recognised as an Important Bird Area (IBA) by BirdLife International because they support populations of the resident Ryukyu green pigeons, as well as migrating whimbrels.
