Pagan Reed Warbler
The Pagan reed warbler (''Acrocephalus yamashinae'') is an extinct species of passerine bird in the family Acrocephalidae, sometimes considered a subspecies of the nightingale reed warbler. It originally occurred on Pagan Island and "was extinct by the late 1970s". More precisely, in the 1970s, the 1980s, in 2000 and in 2010, the bird could not be found and is therefore presumed to be extinct. Taxonomy The genus Acrocephalus was introduced in 1811 by the German naturalist Johann Andreas Naumann and his son Johann Friedrich Naumann. Many species have a flat head profile, which gives rise to the genus name, ''Acrocephalus'' from Ancient Greek ''akros'', "highest", and ''kephale'', "head". It is possible that the Naumanns thought ''akros'' meant "sharp-pointed". The specific epithet ''yamashinae'' commemorates the Japanese ornithologist Yoshimaro Yamashina, who founded the Yamashina Institute for Ornithology The is a non-profit scientific research organization in Japan, specia ...

Bird Extinction
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 common ostrich. There are over 11,000 living species and they are split into 44 orders. More than half are passerine or "perching" birds. Birds have wings 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 waterbi ...

Ancient Greek
Ancient Greek (, ; ) includes the forms of the Greek language used in ancient Greece and the classical antiquity, ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Greek Dark Ages, Dark Ages (), the Archaic Greece, Archaic or Homeric Greek, Homeric period (), and the Classical Greece, Classical period (). Ancient Greek was the language of Homer and of fifth-century Athens, fifth-century Athenian historians, playwrights, and Ancient Greek philosophy, philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Homeric Greek, Epic and Classical periods of the language, which are the best-attested periods and considered most typical of Ancient Greek. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extinct Birds Of Oceania
Extinction is the termination of an organism by the death of its last member. A taxon may become functionally extinct before the death of its last member if it loses the capacity to reproduce and recover. As 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. Over five billion species are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryotes globally, possibly many times more if microorganisms are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, and mammoths. Through evolution, species arise through the process of speciation. Species become extinct when they are no longer able to survive in changing conditions or against superior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Yamashina Institute For Ornithology
The is a non-profit scientific research organization in Japan, specializing in ornithology. History The Yamashina Institute for Ornithology was founded by Dr. Yoshimaro Yamashina at his home in Shibuya, Tokyo as a private museum to store his collection of bird specimens and books. Marquis Yamashina was the second son of Prince Yamashina Kikumaro. He opened his museum to the public in 1942. At the institute, Yamashina conducted research into bird taxonomy based on chromosomes, and wrote numerous technical journal articles and books on ornithology. The Institute relocated to its present location approximately 30 kilometer east of Tokyo at Abiko, Chiba in 1984. The institute has maintained close ties to the Imperial Family of Japan. It is chaired by Prince Akishino, younger brother to the Crown Prince Naruhito of Japan, and their younger sister Princess Sayako worked as a researcher at the institute from 1992 to 2005, where she specialized in the study of kingfishers.

Yoshimaro Yamashina
Marquis was a Japanese ornithologist. He was the founder of the Yamashina Institute for Ornithology. Biography Yamashina was born in Kōjimachi, Tokyo, the second son of Prince Kikumaro Yamashina and Princess Noriko (Kujo) Yamashina. Through his mother, a half-sister of the Crown Princess Sadako, he was the nephew of the then Crown Prince Yoshihito, the future Taishō Emperor. He developed a love of birds at an early age, which were found in abundance on the vast Yamashina estate in Tokyo. He was presented with a stuffed mandarin duck for his sixth birthday present. Yamashina attended the Gakushuin Peer's School, and per the orders of Emperor Meiji entered the Imperial Japanese Army, graduating from the 33rd class of the Imperial Japanese Army Academy with a specialty in artillery. In 1920, per a revision in the Imperial Household Law, he lost his status as an imperial prince, and became a member of the ''kazoku'' with the peerage title of marquis (''kōshaku'') on 2 ...

Ornithologist
Ornithology, from Ancient Greek ὄρνις (''órnis''), meaning "bird", and -logy from λόγος (''lógos''), meaning "study", is a branch of zoology dedicated to the study of birds. Several aspects of ornithology differ from related disciplines, due partly to the high visibility and the aesthetic appeal of birds. It has also been an area with a large contribution made by amateurs in terms of time, resources, and financial support. Studies on birds have helped develop key concepts in biology including evolution, behaviour and ecology such as the definition of species, the process of speciation, instinct, learning, ecological niches, guilds, insular biogeography, phylogeography, and conservation. While early ornithology was principally concerned with descriptions and distributions of species, ornithologists today seek answers to very specific questions, often using birds as models to test hypotheses or predictions based on theories. Most modern biological theories apply ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet, species epithet, or epitheton) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Etymology Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the ...

Passerine
A passerine () is any bird of the order Passeriformes (; from Latin 'sparrow' and '-shaped') which includes more than half of all bird species. Sometimes known as perching birds, passerines generally have an anisodactyl arrangement of their toes (three pointing forward and one back), which facilitates perching. With more than 140 families and some 6,500 identified species, Passeriformes is the largest order of birds and one of the most diverse clades of terrestrial vertebrates, representing 60% of birds.Ericson, P.G.P. et al.
