Acanthisitti
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 ...

Passerine
A passerine () is any bird of the order Passeriformes (; from Latin 'sparrow' and '-shaped'), which includes more than half of all bird species. Sometimes known as perching birds, passerines are distinguished from other orders of birds by the arrangement of their toes (three pointing forward and one back), which facilitates perching. With more than 140 families and some 6,500 identified species, Passeriformes is the largest clade of birds and among the most diverse clades of terrestrial vertebrates, representing 60% of birds.Ericson, P.G.P. et al. (2003Evolution, biogeography, and patterns of diversification in passerine birds ''J. Avian Biol'', 34:3–15.Selvatti, A.P. et al. (2015"A Paleogene origin for crown passerines and the diversification of the Oscines in the New World" ''Molecular Phylogenetics and Evolution'', 88:1–15. Passerines are divided into three clades: Acanthisitti (New Zealand wrens), Tyranni (suboscines), and Passeri (oscines or songbirds). The passeri ...

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] |
Suboscine
The Tyranni (suboscines) are a suborder of passerine birds that includes more than 1,000 species, the large majority of which are South American. It is named after the type genus '' Tyrannus''. These have a different anatomy of the syrinx musculature than the oscines (songbirds of the larger suborder Passeri), hence the common name of ''suboscines''. The available morphological, DNA sequence, and biogeographical data, as well as the (scant) fossil record, agree that these two major passerine suborders are evolutionarily distinct clades. Systematics The suborder Tyranni is divided into two infraorders: the Eurylaimides and the Tyrannides. The New Zealand wrens in the family Acanthisittidae are placed in a separate suborder Acanthisitti. The Eurylaimides contain the Old World suboscines – mainly distributed in tropical regions around the Indian Ocean – and a single American species, the sapayoa: * Philepittidae: asities * Eurylaimidae: typical broadbills * Calyptomeni ...

Rifleman (bird)
The rifleman (''Acanthisitta chloris'') (Māori: ''titipounamu'') is a small insectivorous passerine bird that is endemic to New Zealand. It belongs to the family Acanthisittidae, also known as the New Zealand wrens, of which it is one of only two surviving species. The rifleman resembles a wren in form, but is not related to the family of true wrens, Troglodytidae, nor the fairy-wrens of Australia. Taxonomy The rifleman was described by Anders Sparrman in 1787 based on a bird collected in Queen Charlotte Sound in the Marlborough Sounds of New Zealand's South Island. He originally placed it in the nuthatch genus ''Sitta''. Frédéric de Lafresnaye placed it in its own monotypic genus ''Acanthisitta'' in 1842. The name ''Acanthisitta'' is a portmanteau of the thornbill genus '' Acanthiza'' and the genus ''Sitta''. The rifleman is named after a colonial New Zealand regiment because its plumage drew similarities with the military uniform of a rifleman. Description The riflem ...

Pachyplichas
''Pachyplichas'' is a genus containing two extinct species of New Zealand wren, a family of small birds endemic to New Zealand. Species * †'' P. yaldwyni'' (South Island stout-legged wren) – South Island, New Zealand * †'' P. jagmi'' (North Island stout-legged wren) – North Island, New Zealand Description The stout-legged wrens formed a species pair. They had reduced wings and robust legs indicating that they were adapted to a terrestrial existence and were either flightless or nearly so.Millener (1988). Genetic evidence has indicated that Pachyplichas is nested within ''Xenicus ''Xenicus'' is a genus of birds in the family ''Acanthisittidae''. It contains New Zealand wrens.

Long-billed Wren (New Zealand)
The long-billed wren (''Dendroscansor decurvirostris'') was a species of New Zealand wren endemic to the South Island of New Zealand. It was the only species in the genus ''Dendroscansor''. It shares the name "long-billed wren" with the Brazilian bird '' Cantorchilus longirostris.'' New Zealand's long-billed wren was a small bird with stout legs and tiny wings. Its reduced sternum suggests that it had weak flight muscles and was probably flightless, like the recently extinct Lyall's wren. Its weight is estimated at 30 g, which makes it heavier than any surviving New Zealand wren, but lighter than the also-extinct stout-legged wren. The bill of this species was both long and curved, unlike that of all other acanthisittid wrens. The species is known only from subfossils at four sites in Northwest Nelson and Southland; it seems to have been absent from the North Island and eastern South Island. The holotype was collected in 1986 from Moonsilver Cave, on Barrans Flat, near Tak ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wren
Wrens are a family of brown passerine birds in the predominantly New World family Troglodytidae. The family includes 88 species divided into 19 genera. Only the Eurasian wren occurs in the Old World, where, in Anglophone regions, it is commonly known simply as the "wren", as it is the originator of the name. The name ''wren'' has been applied to other, unrelated birds, particularly the New Zealand wrens (Acanthisittidae) and the Australian wrens (Maluridae). Most wrens are visually inconspicuous though they have loud and often complex songs. Exceptions include the relatively large members of the genus ''Campylorhynchus'', which can be quite bold in their behaviour. Wrens have short wings that are barred in most species, and they often hold their tails upright. Wrens are primarily insectivorous, eating insects, spiders and other small invertebrates, but many species also eat vegetable matter and some eat small frogs and lizards.

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).

Oscines
A songbird is a bird belonging to the suborder Passeri of the perching birds (Passeriformes). Another name that is sometimes seen as the scientific or vernacular name is Oscines, from Latin ''oscen'', "songbird". The Passeriformes contains 5000 or so speciesEdwards, Scott V. and John Harshman. 2013. Passeriformes. Perching Birds, Passerine Birds.

New Zealand Rock Wren
The New Zealand rock wren (''Xenicus gilviventris'') is a small New Zealand wren (family Acanthisittidae) endemic to the South Island of New Zealand. Its Māori names include ("little complaining bird"), , and ("twitch", after its bobbing motion). Outside New Zealand it is sometimes known as the rockwren to distinguish it from the unrelated rock wren of North America. The rock wren is currently restricted to alpine and subalpine areas of the South Island. It is a poor flier and highly terrestrial, feeding in low scrub, open scree, and rockfalls. The rock wren and rifleman are the only two surviving New Zealand wrens; the rock wren's closest relatives were the extinct stout-legged wrens, followed by the extinct bushwren. Its numbers are declining due to predation by introduced mammals. Description The rock wren is a very small, almost tailless bird that prefers to hop and run on its long legs, and uses its rounded wings to fly only short distances. Males are 16 g, females 2 ...

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. Its reduced wings and robust legs indicate that it was strongly adapted to a terrestrial existence and was either flightless Flightless birds are birds ...
