Kona Grosbeak
The Kona grosbeak (''Chloridops kona'') is an extinct species of Hawaiian honeycreeper. The Kona grosbeak was endemic to naio (''Myoporum sandwicense'') forests on ʻaʻā lava flows at elevations of near the Kona District on the island of Hawaii. The species was already very rare when it was first discovered, being found in only about , and was last collected in 1894. Reasons for its extinction are not very well known. The genus is known from fossils from Kauai, Oahu and Maui. It was unknown to the Native Hawaiians, and thus a name for it does not exist in the Hawaiian language. Description The Kona grosbeak, at , was a medium-sized, chunky bird. Its plumage was a dull olive green, and did not display sexual dimorphism. The bird had a large head and a giant, brownish-gray beak. Diet The Kona grosbeak was a frugivore, with a large beak adapted to break through the hard endocarp of dried naio (''Myoporum sandwicense'') fruits. It may have also taken green naio fruit and le ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scott Barchard Wilson
Scott Barchard Wilson (1865–1923) was a British people, British ornithologist and explorer. Wilson was the son of the chemist George Fergusson Wilson. In 1887, he was sent by his professor Alfred Newton to study and collect birds in Hawaii. On his return he wrote ''Aves Hawaiienses'' (1890-1899) with Arthur Humble Evans, illustrated by Frederick William Frohawk. References * Fuller, Errol (2000): ''Extinct Birds, 2nd edition''.

Naturalis Biodiversity Center - RMNH
Naturalis Biodiversity Center ( nl, Nederlands Centrum voor Biodiversiteit Naturalis) is a national museum of natural history and a research center on biodiversity in Leiden, Netherlands. It was named the European Museum of the Year 2021. Although its current name and organization are relatively recent, the history of Naturalis can be traced back to the early 1800s. Its collection includes approximately 42 million specimens, making it one of the largest natural history collections in the world. History The beginnings of Naturalis go back to the creation of the Rijksmuseum van Natuurlijke Historie (abbreviated RMNH, National Museum of Natural History) by Dutch King William I on August 9, 1820. In 1878, the geological and mineralogical collections of the museum were split off into a separate museum, remaining distinct until the merger of the Rijksmuseum van Natuurlijke Historie with the Rijksmuseum van Geologie en Mineralogie (abbreviated RGM) in 1984, to form the Nationaal Natu ...

Extinct Birds Of Hawaii
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 Endling, last individual of the species, although the Functional extinction, capacity to breed and recover may have been lost before this point. Because a species' potential Range (biology), range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxon, Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the Fossil, fossil record) after a period of apparent absence. More than 99% of all species that ever Life, 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 a ...

Chloridops
''Chloridops'' is an extinct genus of Hawaiian honeycreeper in the subfamily Carduelinae of the family Fringillidae. Distribution The birds were endemic to Hawaii. It comprised three species: two on the Big Island of Hawaii; and one that inhabited Kauai, Oahu, and Maui. Species The genus includes the following three species: *Kona grosbeak The Kona grosbeak (''Chloridops kona'') is an extinct species of Hawaiian honeycreeper.

Greater Koa Finch
The greater koa finch (''Rhodacanthis palmeri'') was a species of finch in the family Fringillidae. It was found only in the Hawaiian Islands. It has been extinct since the late 19th century. Description The bird was about 7–8 in (18–20 cm) long when fully grown. It was the largest known honey-creeper, although its typical weight is unknown. The bird was sexually dimorphic; the male was brilliant scarlet-orange on head, neck, and breast, with lighter orange on its bottom, and olive brown with orange touches on back, wings, and tail; however, the female was brownish olive, and somewhat lighter below. It had a thick black bill which allowed it to break open seed pods that were found in the trees. In historical times, its range was largely confined to the Kona District of the island of Hawaii, although it was observed in the Kīlauea area in 1895. It was much more widespread prior to the arrival of humans in Hawaii, and related species lived on other islands. In Kona, it ...

Rhodacanthis
''Rhodacanthis'' is an extinct genus of Hawaiian honeycreepers commonly known as koa finches. All four species were endemic to the Hawaiian Islands. Members of this genus were granivores, with bills adapted to the seeds and pods of legumes. The two species that became extinct in the 1890s, '' R. flaviceps'' and '' R. palmeri'', inhabited upper elevation mesic forests dominated by koa ''(Acacia koa'') on the island of Hawaii. Both were large birds; ''R. flaviceps'' measured , while ''R. palmeri'' was in length. The combination of a giant bill with brightly colored plumage (yellow for ''R. flaviceps'', orange for ''R. palmeri'') gave the males a very striking appearance. Koa seeds were the preferred food for the two species, but caterpillars were taken if necessary. The two prehistoric species, '' R. forfex'' and '' R. litotes'', were denizens of more lowland tropical dry forests and shrublands on Kauai, Maui, and Oahu. It is speculated that koaia (''Acacia koaia'') was an im ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Ibis
''Ibis'' (formerly ''The Ibis''), subtitled ''the International Journal of Avian Science'', is the peer-reviewed scientific journal of the British Ornithologists' Union. It was established in 1859. Topics covered include ecology, conservation, behaviour, palaeontology, and taxonomy of birds. The editor-in-chief is Dominic J. McCafferty (University of Glasgow). The journal is published by Wiley-Blackwell in print and online. It is available free on the internet for institutions in the developing world through the OARE scheme (Online Access to Research in the Environment). History In 1858 the British Ornithologists' Union (BOU) was formed. It was the first organization, devoted solely to the study of birds. One year later members of the BOU founded a (Quarterly) "Magazine of General Ornithology," entitled ''The Ibis''. Series and editors * Series 1 was published from 1859 to 1864, in six volumes and 24 issues. The first editor was Philip Lutley Sclater (1829–1913).Sep. ixvif ...

Invertebrate
Invertebrates are a paraphyletic group of animals that neither possess nor develop a vertebral column (commonly known as a ''backbone'' or ''spine''), derived from the notochord. This is a grouping including all animals apart from the chordate subphylum Vertebrata. Familiar examples of invertebrates include arthropods, mollusks, annelids, echinoderms and cnidarians. The majority of animal species are invertebrates; one estimate puts the figure at 97%. Many invertebrate taxa have a greater number and variety of species than the entire subphylum of Vertebrata. Invertebrates vary widely in size, from 50 μm (0.002 in) rotifers to the 9–10 m (30–33 ft) colossal squid. Some so-called invertebrates, such as the Tunicata and Cephalochordata, are more closely related to vertebrates than to other invertebrates. This makes the invertebrates paraphyletic, so the term has little meaning in taxonomy. Etymology The word "invertebrate" comes from the Latin word ''vertebra'', whi ...

Freycinetia Arborea
''Freycinetia arborea'', ''Ieie'', is a densely branched, brittle, woody climber in the family Pandanaceae, endemic to the Pacific Islands. ''Ieie'' is found in moist forest on the Hawaiian, Marquesas, Austral, Society, and Cook Islands. It grows into the forest canopy, attaching itself to a host tree using aerial roots. It may also grow as a sprawling tangle on the forest floor. The shiny green leaves have pointed ends and are spiny on the lower side of the midrib and along the edges. Leaves measure long and wide, and are spirally arranged around the ends of branches. Flowers form on spike-like inflorescences at the end of branches, and are either staminate or pistillate. Staminate spikes are yellowish-white and up to in length. Pistillate spikes are but elongate to once fruit are produced. Three to four spikes are surrounded by orange-salmon bracts. Fruit is long and contains many seeds. The bracts and fruit of the ''ieie'' were a favorite food of the '' ōū' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fruit
In botany, a fruit is the seed-bearing structure in flowering plants that is formed from the ovary after flowering. Fruits are the means by which flowering plants (also known as angiosperms) disseminate their seeds. Edible fruits in particular have long propagated using the movements of humans and animals in a symbiotic relationship that is the means for seed dispersal for the one group and nutrition for the other; in fact, humans and many animals have become dependent on fruits as a source of food. Consequently, fruits account for a substantial fraction of the world's agricultural output, and some (such as the apple and the pomegranate) have acquired extensive cultural and symbolic meanings. In common language usage, "fruit" normally means the seed-associated fleshy structures (or produce) of plants that typically are sweet or sour and edible in the raw state, such as apples, bananas, grapes, lemons, oranges, and strawberries. In botanical usage, the term "fruit" also i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endocarp
Fruit anatomy is the plant anatomy of the internal structure of fruit. Fruits are the mature ovary or ovaries of one or more flowers. They are found in three main anatomical categories: aggregate fruits, multiple fruits, and simple fruits. Aggregate fruits are formed from a single compound flower and contain many ovaries or fruitlets. Examples include raspberries and blackberries. Multiple fruits are formed from the fused ovaries of multiple flowers or inflorescence. Examples include fig, mulberry, and pineapple. Simple fruits are formed from a single ovary and may contain one or many seeds. They can be either fleshy or dry. In fleshy fruit, during development, the pericarp (ovary wall) and other accessory structures become the fleshy portion of the fruit. The types of fleshy fruits are berries, pomes, and drupes. In some fruits, the edible portion is not derived from the ovary, but rather from the aril, such as the mangosteen or pomegranate, and the pineapple from which tis ...
