Thambetochen
Thambetochen is an extinct genus of moa-nalo duck. It contains two species, the Maui Nui moa-nalo (''T. chauliodous'') and the smaller O'ahu moa-nalo (''T. xanion''). The former was found on Maui and Molokai on Hawaii, the latter was found on Oahu. These birds were large, flightless ducks, with robust legs but small wings, which had evolved in isolation, on islands without terrestrial mammals. Their beaks had tooth-like lamella (anatomy), lamellae and their diet was plants which they digested through hindgut fermentation. These birds were likely driven to extinction when the islands were colonised by Polynesians. References [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moa-nalo
The moa-nalo are a group of extinct aberrant, goose-like ducks that lived on the larger Hawaiian Islands, except Hawaii itself, in the Pacific. They were the major herbivores on most of these islands until they became extinct after human settlement. Description The moa-nalo (the name literally means "lost fowl"; the plural and the singular are the same) were unknown to science, having been wiped out before the arrival of James Cook (1778), until the early 1980s, when their subfossil remains were discovered in sand dunes on the islands of Molokai and Kauai. Subsequently, bones were found on Maui, Oahu, and Lānai, in lava tubes, lake beds, and sinkholes. They represent four species in three genera so far: * ''Chelychelynechen quassus'' (turtle-jawed moa-nalo) from Kauai * ''Ptaiochen pau'' (small-billed moa-nalo) from Maui * ''Thambetochen xanion'' (O'ahu moa-nalo) from Oahu * ''Thambetochen chauliodous'' (Maui Nui large-billed moa-nalo) from Maui, Lānai and Molokai (Maui Nui) ...

Maui Nui Moa-nalo
The Maui Nui large-billed moa-nalo (''Thambetochen chauliodous''), also known as the Maui Nui moa-nalo, is one of two species of moa-nalo in the genus '' Thambetochen''. Moa-nalo are a group of extinct, flightless, large goose-like ducks, which evolved in the Hawaiian Islands of the North Pacific Ocean. Distribution and habitat The genus and species were originally described in 1976 from subfossil material collected from the Moomomi Dunes, on the island of Molokai. Remains of the bird have also been recovered from Ilio Point on Molokai as well as from lava tubes on the southern slopes of the volcanic mountain of Haleakalā on the nearby island of Maui. Both Molokai and Maui are parts of what used to be the much larger prehistoric island of Maui Nui Maui Nui or Greater Maui, is a modern geologists' name given to a prehistoric Hawaiian Island built from seven shield volcanoes. ''Nui'' means "great/large" in the Hawaiian language. 1.2 million years ago, Maui Nui was , 40% larg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Late Quaternary Prehistoric Birds
Late Quaternary prehistoric birds are avian taxa that became extinct during the Late Quaternary – the Holocene or Late Pleistocene – and before recorded history, or more precisely, before they could be studied alive by ornithological science. They became extinct before the period of global scientific exploration that started in the late 15th century. In other words, this list basically deals with extinctions between 40,000 BC and 1500 AD. For the purposes of this article, a "bird" is any member of the clade Neornithes, that is, any descendant of the most recent common ancestor of all currently living birds. The birds are known from their remains, which are subfossil (not fossilized, or not completely fossilized). Some are also known from folk memory, as in the case of Haast's eagle in New Zealand. As the remains are not completely fossilized, they may yield organic material for molecular analyses to provide additional clues for resolving their taxonomic affil ...

Anatidae
The Anatidae are the biological family of water birds that includes ducks, geese, and swans. The family has a cosmopolitan distribution, occurring on all the world's continents except Antarctica. These birds are adapted for swimming, floating on the water surface, and in some cases diving in at least shallow water. The family contains around 174 species in 43 genera. (The magpie goose is no longer considered to be part of the Anatidae and is now placed in its own family, Anseranatidae.) They are generally herbivorous, and are monogamous breeders. A number of species undertake annual migrations. A few species have been domesticated for agriculture, and many others are hunted for food and recreation. Five species have become extinct since 1600, and many more are threatened with extinction. Description and ecology The ducks, geese, and swans are small- to large-sized birds with a broad and elongated general body plan. Diving species vary from this in being rounder. Extant s ...

Holocene
The Holocene ( ) is the current geological epoch. It began approximately 11,650 cal years Before Present (), after the Last Glacial Period, which concluded with the Holocene glacial retreat. The Holocene and the preceding Pleistocene together form the Quaternary period. The Holocene has been identified with the current warm period, known as MIS 1. It is considered by some to be an interglacial period within the Pleistocene Epoch, called the Flandrian interglacial.Oxford University Press – Why Geography Matters: More Than Ever (book) – "Holocene Humanity" section https://books.google.com/books?id=7P0_sWIcBNsC The Holocene corresponds with the rapid proliferation, growth and impacts of the human species worldwide, including all of its written history, technological revolutions, development of major civilizations, and overall significant transition towards urban living in the present.

Polynesians
Polynesians form an ethnolinguistic group of closely related people who are native to Polynesia (islands in the Polynesian Triangle), an expansive region of Oceania in the Pacific Ocean. They trace their early prehistoric origins to Island Southeast Asia and form part of the larger Austronesian ethnolinguistic group with an Urheimat in Taiwan. They speak the Polynesian languages, a branch of the Oceanic subfamily of the Austronesian language family. there were an estimated 2 million ethnic Polynesians (full and part) worldwide, the vast majority of whom either inhabit independent Polynesian nation-states (Samoa, Niue, Cook Islands, Tonga, and Tuvalu) or form minorities in countries such as Australia, Chile (Easter Island), New Zealand, France (French Polynesia and Wallis and Futuna), and the United States (Hawaii and American Samoa), in addition to the British Overseas Territory of the Pitcairn Islands. New Zealand had the highest population of Polynesians, estimated at 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Fauna Of Hawaii
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Oahu
Oahu () (Hawaiian language, Hawaiian: ''Oʻahu'' ()), also known as "The Gathering place#Island of Oʻahu as The Gathering Place, Gathering Place", is the third-largest of the Hawaiian Islands. It is home to roughly one million people—over two-thirds of the population of the U.S. state of Hawaii. The island of O’ahu and the Northwestern Hawaiian Islands constitute the City and County of Honolulu, Hawaii, City and County of Honolulu. The state capital, Honolulu, is on Oʻahu's southeast coast. Oʻahu had a population of 1,016,508 according to the 2020 U.S. Census, up from 953,207 people in 2010 (approximately 70% of the total 1,455,271 population of the State of Hawaii, with approximately 81% of those living in or near the Honolulu urban area). Name The Island of O{{okinaahu in Hawaii is often nicknamed (or translated as) ''"The Gathering Place"''. It appears that O{{okinaahu grew into this nickname; it is currently the most populated Hawaiian islands, Hawaiian Island, how ...
