Kauaʻi ʻakialoa
The Kauai ʻakialoa (''Akialoa stejnegeri'') was a Hawaiian honeycreeper in the subfamily Carduelinae of the family Fringillidae. It was endemic to the island of Kauai, Hawaii. It became extinct in the 20th century due to introduced avian disease and habitat loss. The Kauai ʻakialoa was about seven and a half inches in length and had a very long downcurved bill, which covered one third of its length. The adult males were bright olive-yellow on top and yellow on the bottom. The throat, breast, and sides of the body were olive-yellow. The females, however, were green-gray above and had a shorter bill. Habitat and behavior The Kauai ʻakialoa was believed to have lived in forests above above sea level, but was frequently observed flying to the lower elevations of the island. This once very rare and unique bird used its long curved bill to reach the nectar of ''lobelias'' and '' ʻohiʻa'' blossoms. It also ate insects from under tree bark and from under mats of lichens and moss ... [...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''.

Invasive Species
An invasive species otherwise known as an alien is an introduced organism that becomes overpopulated and harms its new environment. Although most introduced species are neutral or beneficial with respect to other species, invasive species adversely affect habitats and bioregions, causing ecological, environmental, and/or economic damage. The term can also be used for native species that become harmful to their native environment after human alterations to its food webfor example the purple sea urchin (''Strongylocentrotus purpuratus'') which has decimated kelp forests along the northern California coast due to overharvesting of its natural predator, the California sea otter (''Enhydra lutris''). Since the 20th century, invasive species have become a serious economic, social, and environmental threat. Invasion of long-established ecosystems by organisms is a natural phenomenon, but human-facilitated introductions have greatly increased the rate, scale, and geographic range of ...

Bird Extinctions Since 1500
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 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 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 waterbirds, have further evolved for swimming. Bird ...

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 ...

IUCN
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Puaiohi
The puaiohi (''Myadestes palmeri''), or small Kauai thrush, is a rare species of songbird in the Thrush (bird), thrush family, Turdidae, that is Endemism, endemic to the Hawaiian island of Kauai, Kauai. It is closely related to the other three endemic Hawaiian thrushes, the Kāmaʻo, kāmao, Olomaʻo, olomao, and ‘Ōma’o, ōmao. It was first collected by Henry Palmer in 1891 at Halemanu around the entrance to the Koke'e State Park, Kōkee State Park. Description The plumage is mostly nondescript, with slaty-brown upperparts and a light gray breast and belly below. Birds have a black bill and pinkish feet. A white eye ring is also fairly prominent and helps distinguish this bird from the other Hawaiian thrushes. Males and females are highly similar in appearance. Juveniles show a pattern transitioning from a spotted whitish-buff above to a scalloped gray-brown below.Collar, N. J. (2005). Puaiohi (''Myadestes palmeri'').

Endangered Species Act
The Endangered Species Act of 1973 (ESA or "The Act"; 16 U.S.C. § 1531 et seq.) is the primary law in the United States for protecting imperiled species. Designed to protect critically imperiled species from extinction as a "consequence of economic growth and development untempered by adequate concern and conservation", the ESA was signed into law by President Richard Nixon on December 28, 1973. The Supreme Court of the United States described it as "the most comprehensive legislation for the preservation of endangered species enacted by any nation"."Tennessee Valley Authority v. Hill" 437 U.S. 153 (1978) Retrieved 24 November 2015. The purposes of the ESA are two-fold: to prevent extinction and to recover species to the point where the law's protections are not needed.

Endangered Species
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are considered when assessing the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
