New Zealand Wren
The New Zealand wrens are a family (Acanthisittidae) of tiny passerines endemic to New Zealand. They were represented by seven Holocene species in four or five genera, although only two species in two genera survive today. They are understood to form a distinct lineage within the passerines, but authorities differ on their assignment to the oscines or suboscines (the two suborders that between them make up the Passeriformes). More recent studies suggest that they form a third, most ancient, suborder Acanthisitti and have no living close relatives at all. They are called "wrens" due to similarities in appearance and behaviour to the true wrens (Troglodytidae) but are not members of that family. New Zealand wrens are mostly insectivorous foragers of New Zealand's forests, with one species, the New Zealand rock wren, being restricted to alpine areas. Both the remaining species are poor fliers and four of the five extinct species are known or suspected to have been flightless. Along ...

South Island Stout-legged Wren
The South Island stout-legged wren or Yaldwyn's wren (''Pachyplichas yaldwyni'') is an extinct species of New Zealand wren, a family of small birds endemic to New Zealand. History and etymology The holotype is a right tarsometatarsus (NMNZS 22683 in the collections of the National Museum) collected on 29 September 1983 from the Honeycomb Hill Cave. The specific epithet honours Dr John Yaldwyn, Director of the National Museum of New Zealand in Wellington, in recognition of his contributions to avian palaeontology. Description It was the largest (by weight) of the New Zealand wrens. The morphology of the wren indicates that it was strongly adapted to a terrestrial existence. Radiocarbon dates for the assemblages with which it is associated range from 25,000 BP to 1,000 BP. Either flightless or nearly so, it became extinct following the occupation of New Zealand by the Polynesian ancestors of the Māori, and the associated introduction of the ''kiore'' (Pacific rat).

North Island Stout-legged Wren
The North Island stout-legged wren or Grant-Mackie's wren (''Pachyplichas jagmi'') is an extinct species of New Zealand wren, a family of small birds endemic to New Zealand. History and etymology The holotype is a right tarsometatarsus (AU 7102.20 in the collections of the Auckland University Geology Department) collected on 25 August 1978 from the Ruakuri Cave in the Waitomo District of North Island of New Zealand. The specific epithet honours Dr John Grant-Mackie, Associate Professor of Geology at Auckland University, in recognition of his support for graduate students and for contributions to avian palaeontology.Millener (1988). Description This wren is similar to, though smaller than, its congener from South Island, the South Island stout-legged wren (''Pachyplichas yaldwyni''), with which it forms a species pair.

Flightless Bird
Flightless birds are birds that through evolution lost the ability to fly. There are over 60 extant species, including the well known ratites (ostriches, emu, cassowaries, rheas, and kiwi) and penguins. The smallest flightless bird is the Inaccessible Island rail (length 12.5 cm, weight 34.7 g). The largest (both heaviest and tallest) flightless bird, which is also the largest living bird, is the ostrich (2.7 m, 156 kg). Many domesticated birds, such as the domestic chicken and domestic duck, have lost the ability to fly for extended periods, although their ancestral species, the red junglefowl and mallard, respectively, are capable of extended flight. A few particularly bred birds, such as the Broad Breasted White turkey, have become totally flightless as a result of selective breeding; the birds were bred to grow massive breast meat that weighs too much for the bird's wings to support in flight. Flightlessness has evolved in many different birds independently, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lyall's Wren
Lyall's wren or the Stephens Island wren (''Traversia lyalli'') is a small, extinct, flightless passerine belonging to the family Acanthisittidae, the New Zealand wrens. It was once found throughout New Zealand, but when it came to the attention of scientists in 1894, its last refuge was Stephens Island in Cook Strait. Often claimed to be a species driven extinct by a single creature (a lighthouse keeper's cat named Tibbles), the wren in fact fell victim to the island's numerous feral cats. The wren was described almost simultaneously by both Walter Rothschild and Walter Buller. It became extinct shortly after. Taxonomy The bird's scientific name commemorates the assistant lighthouse keeper, David Lyall, who first brought the bird to the attention of science. It was described as a distinct genus, ''Traversia'', in honour of naturalist and curio dealer Henry H. Travers, who procured many specimens from Lyall. ''Traversia'' is a member of the family Acanthisittidae, or the New Z ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pleistocene
The Pleistocene ( , often referred to as the ''Ice age'') is the geological Epoch (geology), epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek grc, label=none, πλεῖστος, pleīstos, most and grc, label=none, καινός, kainós (latinized as ), 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing Great American Interchang ...

Kuiornis
''Kuiornis indicator'' is an extinct New Zealand wren (Acanthisittidae) known from the early Miocene (19–16 million years ago) St Bathans fauna in Central Otago. It is known from a holotype proximal right tarsometatarsus (NMNZ S.50929). Amongst acanthisittids it is most closely related to the living rifleman A rifleman is an infantry soldier armed with a rifling, rifled long gun. Although the rifleman role had its origin with 16th century hand cannoneers and 17th century musketeers, the term originated in the 18th century with the introduction o ....

Xenicus Longipes
The bushwren (''Xenicus longipes''), also known as the mātuhituhi in Māori, was a very small and almost flightless bird that was endemic to New Zealand. It had three subspecies on each of the major islands of New Zealand, the North Island, South Island, and Stewart Island and nearby smaller islands. The species disappeared gradually after the introduction of invasive mammalian predators, last being seen on the North Island in 1955 and the South Island in 1968. Attempts were made to save the remaining population on small islands off Stewart Island, but they ultimately failed with the death of the last remaining known birds in 1972. Taxonomy German naturalist Johann Friedrich Gmelin described the bushwren in 1789. Description It grew to about 9 cm long and 16 g in weight. It fed mostly on invertebrates, which it captured by running along the branches of trees. It nested on or near the ground. Extinction It was widespread throughout the main islands of the country until the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
