Kauaʻi ʻakialoa
The Kauai ʻakialoa (''Akialoa stejnegeri'') is an Bird extinction, extinct species of Hawaiian honeycreeper in the subfamily Carduelinae of the family Fringillidae. It was endemic to the island of Kauai, Hawaii, and 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 ...

Hawaiian Honeycreepers
Hawaiian honeycreepers are a group of small birds endemic to Hawaii. They are members of the finch family Fringillidae, closely related to the rosefinches (''Carpodacus''), but many species have evolved features unlike those present in any other finch. Their great morphological diversity is the result of adaptive radiation in an insular environment. Many have been driven to extinction since the first humans arrived in Hawaii, with extinctions increasing over the last two centuries following European discovery of the islands, with habitat destruction and especially invasive species being the main causes. Taxonomy Before the introduction of molecular phylogenetic techniques, the relationship of the Hawaiian honeycreepers to other bird species was controversial. The honeycreepers were sometimes categorized as a family Drepanididae,Clements, J. 2007. ''The Clements Checklist of the Birds of the World.'' 6th ed. other authorities considered them a subfamily, Drepanidinae, of Frin ...

Maui Nui ʻakialoa
The Maui Nui ʻakialoa or Lānaʻi ʻakialoa (''Akialoa lanaiensis'') is an extinct species of Hawaiian honeycreeper in the subfamily Carduelinae of the family Fringillidae. It inhabited the islands of Maui, Lānaʻi, and Molokaʻi in Hawaii. Description and habitat The Maui Nui ʻakialoa was a grayish-yellow bird. It was six inches long, with a bill that was an inch and a half in length. It used its long bill to probe bark in search of insects and probe flowers in search of nectar. It is known from three specimens collected on the island of Lānaʻi in 1892. It is also known from fossils on Molokaʻi and Maui. It lived in forests above 200 m of elevation. Extinction The Maui Nui ʻakialoa was driven to extinction by habitat destruction and disease. Invasive species may also have been a factor. References Maui Nui Maui Nui is a modern Geology, geologists' name given to a prehistoric Hawaii, Hawaiian island and the corresponding modern Biogeography, biogeographic ...

Lesser ʻakialoa
The lesser ʻakialoa (''Akialoa obscura'') is an extinct species of Hawaiian honeycreeper in the subfamily Carduelinae of the family Fringillidae. It was endemic to the island of Hawaiʻi. It became extinct due to habitat loss and disappeared at around the same time as its Oʻahu relative. Description It was a yellowish bird with a two-inch-long thin whitish-yellow bill. It had small olive green wings which it used to flit from tree to tree to look for insects like beetles and caterpillars. Behavior It was seen gleaning the trees in search of insects. The bill of the akialoa was also designed for more than bug extraction. The akialoa also fed on nectar in the flowers of lobeliads and o’hia blossoms. Its long bill could easily fit into petals of long flowers and took pollen from flower to flower on its forehead. It was collected at several places. It was once thought to be the same species as the Maui and Oahu form, but when specimens were compared all together the scientis ...

Hoopoe-billed ʻakialoa
The hoopoe-billed ʻakialoa (''Akialoa upupirostris'') is an extinct species of Hawaiian honeycreeper in the subfamily Carduelinae of the family Fringillidae. It inhabited the islands of Kauaʻi and Oʻahu in Hawaii. Description Subfossil remains have been found on the Hawaiian islands of Kauaʻi and Oʻahu. The species was apparently slightly larger than others in the genus '' Akialoa''. A similar but smaller bird from Maui has been discovered but is as yet undescribed. The specific name, ''upupirostris'', is derived from the Latin ''upupa'', hoopoe, and ''rostrum'', bill, and refers to the long sickle-shaped bill which resembles that of the hoopoe. Extinction The species presumably became extinct after the arrival of humans in Hawaii Hawaii ( ; ) is an island U.S. state, state of the United States, in the Pacific Ocean about southwest of the U.S. mainland.

Fringillidae
The true finches are small to medium-sized passerine birds in the family Fringillidae. Finches generally have stout conical bills adapted for eating seeds and nuts and often have colourful plumage. They occupy a great range of habitats where they are usually resident and do not migrate. They have a worldwide native distribution except for Australia and the polar regions. The family Fringillidae contains more than two hundred species divided into fifty genera. It includes the canaries, siskins, redpolls, serins, grosbeaks and euphonias, as well as the morphologically divergent Hawaiian honeycreepers. Many birds in other families are also commonly called "finches". These groups include the estrildid finches ( Estrildidae) of the Old World tropics and Australia; some members of the Old World bunting family ( Emberizidae) and the New World sparrow family ( Passerellidae); and the Darwin's finches of the Galapagos islands, now considered members of the tanager family (Thra ...

Oʻahu ʻakialoa
The Oahu akialoa (''Akialoa ellisiana'') is an extinct species of Hawaiian honeycreeper in the subfamily Carduelinae of the family Fringillidae. It was endemic to the island of Oʻahu in Hawaii. Description The bird was a long-billed insectivorous bird that was found in the high elevation forest. It was a dull colored species, dull green on the belly, bright green on rump and tail, dark olive-gray back and speckled yellow and green on the head. It was mainly an insectivore, using its bill to probe through the bark in search of arthropods, also using its long bill to probe flowers for nectar. Status Since the population was already taking a toll due to the large amount of deforestation, it was susceptible to the avian influenza, more commonly known as the bird flu. This was brought in by mosquitoes who were carrying the virus and were able to spread it within the community. Because of the virus, the population fell to around 4–6 percent of its normal population (Pratt). Scien ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hawaii
Hawaii ( ; ) is an island U.S. state, state of the United States, in the Pacific Ocean about southwest of the U.S. mainland. One of the two Non-contiguous United States, non-contiguous U.S. states (along with Alaska), it is the only state not on the North American mainland, the only state that is an archipelago, and the only state in the tropics. Hawaii consists of 137 volcanic islands that comprise almost the entire Hawaiian Islands, Hawaiian archipelago (the exception, which is outside the state, is Midway Atoll). Spanning , the state is Physical geography, physiographically and Ethnology, ethnologically part of the Polynesian subregion of Oceania. Hawaii's ocean coastline is consequently the List of U.S. states and territories by coastline, fourth-longest in the U.S., at about .

Undescribed Taxon
In taxonomy, an undescribed taxon is a taxon (for example, a species) that has been discovered, but not yet formally described and named. The various Nomenclature Codes specify the requirements for a new taxon to be validly described and named. Until such a description has been published, the taxon has no formal or official name, although a temporary, informal name is often used. A published scientific name may not fulfil the requirements of the Codes for various reasons. For example, if the taxon was not adequately described, its name is called a ''nomen nudum''. It is possible for a taxon to be "undescribed" for an extensive period of time, even if unofficial descriptions are published. An undescribed species may be referred to with the genus name, followed by "sp.", but this abbreviation is also used to label specimens or images that are too incomplete to be identified at the species level. In some cases, there is more than one undescribed species in a genus. In this case, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Holocene Extinction
The Holocene extinction, also referred to as the Anthropocene extinction or the sixth mass extinction, is an ongoing extinction event caused exclusively by human activities during the Holocene epoch. This extinction event spans numerous families of plants and animals, including mammals, birds, reptiles, amphibians, fish, and invertebrates, impacting both terrestrial and marine life, marine species. Widespread degradation of biodiversity hotspots such as coral reefs and rainforests has exacerbated the crisis. Many of these extinctions are undocumented, as the species are often undiscovered before their extinctions. Current extinction rates are estimated at 100 to 1,000 times higher than natural background extinction rates and are accelerating. Over the past 100–200 years, biodiversity loss has reached such alarming levels that some conservation biologists now believe humankind, human activities have triggered a mass extinction, or are on the cusp of doing so. As such, after the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
