Chatham Penguin
The Chatham penguin (''Eudyptes warhami''), also known as the Chatham crested penguin, Chatham Islands penguin, or Warham's penguin, is an extinct species of crested penguin previously endemic to the Chatham Islands of New Zealand. It is known only from subfossil bones and probably became extinct within 150–200 years after Polynesians arrived in the Chatham Islands around 1500 CE. Discovery and description Bones of crested penguins (genus '' Eudyptes'') have been recorded from subfossil deposits on main Chatham Island for years. They had been identified as Fiordland or erect-crested penguins, but Tennyson and Millener noted in 1994 they differed from both those species, and probably represented a species of crested penguin endemic to the Chatham Islands. It was referred to as the "Chatham Island crested penguin", but not formally described and named. As part of a study of the recent evolution of numerous penguin species, subfossil bones from Chatham Island and the mainla ...

Holocene
The Holocene () is the current geologic time scale, geological epoch, beginning approximately 11,700 years ago. It follows the Last Glacial Period, which concluded with the Holocene glacial retreat. The Holocene and the preceding Pleistocene together form the Quaternary period. The Holocene is an interglacial period within the ongoing Ice age, glacial cycles of the Quaternary, and is equivalent to Marine isotope stages, Marine Isotope Stage 1. The Holocene correlates with the last maximum axial tilt towards the Sun of the Earth#Axial tilt and seasons, Earth's obliquity. The Holocene corresponds with the rapid proliferation, growth, and impacts of the human species worldwide, including Recorded history, all of its written history, technological revolutions, development of major civilizations, and overall significant transition towards urban culture, urban living in the present. The human impact on modern-era Earth and its ecosystems may be considered of global significance for th ...

Wairarapa
The Wairarapa (; ), a geographical region of New Zealand, lies in the south-eastern corner of the North Island, east of metropolitan Wellington and south-west of the Hawke's Bay Region. It is lightly populated, having several rural service towns, with Masterton being the largest. It is named after its largest lake, Lake Wairarapa. The region is referred to as The Wairarapa, particularly when used after a preposition (e.g., locals will say they live "in the Wairarapa", and travel "to" and "from the Wairarapa"). Boundaries The Wairarapa is shaped like a rectangle, about long (from Palliser Bay north to Woodville) and wide (from the Tararua Range east to the coast). The Ngāti Kahungunu tribe's boundary for the region is similar. Their tribal area begins at Pōrangahau and ends at Turakirae. It is the southernmost of their three rohe (homelands) running down the eastern North Island from Wairoa. For the Rangitāne tribe, the Wairarapa is part of a wider homeland that include ...

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 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 waterbirds, have fur ...

Late Quaternary Prehistoric Birds
Late Quaternary prehistoric birds are Bird, avian taxa that became extinct during the Late Quaternary – the Late Pleistocene or Early Holocene – and before recorded history, specifically before they could be studied alive by ornithological science. They had died out before the period of global scientific exploration that started in the late 15th century. In other words, this list deals with avian extinctions between Upper Paleolithic, 40,000 BC and AD 1500. 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; as the remains are not completely fossilized, they may yield organic material for molecular analyses to provide additional clues for resolving their Taxonomy (biology), taxonomic affiliations. Some birds are also known from folk memory, as in the case of Haast's eagle in New Zeala ...

Extinct Birds Of The Chatham Islands
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 superio ...

Eudyptes
''Eudyptes'' is a genus of penguins whose members are collectively called crested penguins. The exact number of species in the genus varies between four and eight depending on the authority, and a Chatham Islands species became extinct in recent centuries. All are black and white penguins with yellow crests, red bills and eyes, and are found on Subantarctic islands in the world's southern oceans. All lay two eggs, but raise only one young per breeding season; the first egg laid is substantially smaller than the second. Taxonomy The genus ''Eudyptes'' was introduced by the French ornithologist Louis Pierre Vieillot in 1816; the name is derived from the Ancient Greek words meaning "fine", and meaning "diver". The type species was designated as the western rockhopper penguin by George Robert Gray in 1840. The genus contains eight exant species: * Macaroni penguin, ''Eudyptes chrysolophus'' * Royal penguin, ''Eudyptes schlegeli'' * Northern rockhopper penguin, ''Eudyptes moseleyi' ...

Rockhopper Penguin
The rockhopper penguins are three closely related taxa of crested penguins that have been traditionally treated as a single species and are sometimes split into three species. Not all experts agree on the classification of these penguins. Some consider all three as distinct species, some split the western and eastern forms into the southern rockhopper penguin and keep the northern rockhopper as distinct, while other experts consider all three potential varieties to be one species. Appearance Rockhopper penguins (Eudyptes chrysocome) are among the smaller species of penguin. After reaching full growth, they are about 20 inches or 50 centimetres in height. Males and females cannot be distinguished visually, so a DNA test is conducted by taking a feather from the bird to determine its gender. Like many penguins, rockhopper penguins have a white belly and the rest of their body is black. Some characteristics that differentiate them from the other penguins are their red eyes, orange ...

Snares Penguin
The Snares penguin (''Eudyptes robustus''; ), also known as the Snares crested penguin and the Snares Islands penguin, is a penguin from New Zealand. The species breeds on the Snares Islands, a group of islands off the southern coast of the South Island. It is a yellow-crested penguin, with a size of and a weight of . It has dark blue-black upper parts and white underparts. It has a bright yellow eyebrow-stripe which extends over the eye to form a drooping, bushy crest. It has bare pink skin at the base of its large red-brown bill. The species nests in colonies ranging in size from around 10 nests to around 1200, under forest cover or the open. The main colonies are located on North East Island; other colonies are established on Broughton Island as well as the rocky Western Chain. The Snares penguin's main prey is krill, supplemented by squid and small fish. The species is rated as vulnerable by the International Union for Conservation of Nature (IUCN) as its breeding ran ...

Binomial Nomenclature
In taxonomy, binomial nomenclature ("two-term naming system"), also called binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (often shortened to just "binomial"), a binomen, name, or a scientific name; more informally, it is also called a Latin name. In the International Code of Zoological Nomenclature (ICZN), the system is also called nomenclature, with an "n" before the "al" in "binominal", which is a typographic error, meaning "two-name naming system". The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Hom ...

Marlborough Region
Marlborough District or the Marlborough Region (, or ''Tauihu''), commonly known simply as Marlborough, is one of the 16 regions of New Zealand, located on the northeast of the South Island. It is administered by Marlborough District Council, a unitary authority, performing the functions of both a territorial authority and a regional council. The council is based at Blenheim, the largest town. The unitary region has a population of . Marlborough is known for its dry climate, the Marlborough Sounds, and Sauvignon blanc wine. It takes its name from the earlier Marlborough Province, which was named after John Churchill, 1st Duke of Marlborough, an English general and statesman. Geography Marlborough's geography can be roughly divided into four sections. The south and west sections are mountainous, particularly the southern section, which rises to the peaks of the Kaikōura Ranges. These two mountainous regions are the final northern vestiges of the ranges that make up th ...
