Xenicus is a genus of birds in the family Acanthisittidae . It contains New Zealand wrens.
Lyall's wren was classified as Xenicus lyalli but is quite divergent, so it is placed in its own genus, Traversia.
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. [2] Genetic evidence has indicated that the former genus Pachyplichas is nested within Xenicus, and stout-legged wrens must have evolved from a gracile-legged ancestor. A cladogram is given below.

Moa are an extinct group of flightless birds formerly endemic to New Zealand. During the Late Pleistocene-Holocene, there were nine species. The two largest species, Dinornis robustus and Dinornis novaezelandiae, reached about 3.6 metres (12 ft) in height with neck outstretched, and weighed about 230 kilograms (510 lb) while the smallest, the bush moa, was around the size of a turkey. Estimates of the moa population when Polynesians settled New Zealand circa 1300 vary between 58,000 and approximately 2.5 million.
Wrens are a family, Troglodytidae, of small brown passerine birds. The family includes 96 species and is divided into 19 genera. All species are restricted to the New World except for the Eurasian wren that is widely distributed in the Old World. In Anglophone regions, the Eurasian wren 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).
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. 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" because of similarities in appearance and behaviour to the true wrens (Troglodytidae) but are not members of that family.
The bushwren, also known as the mātuhituhi in the Māori language, 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 / Rakiura 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.
Flightless birds are birds that cannot fly. They have, through evolution, lost the ability to fly. There are over 60 extant species, including the well-known ratites and penguins. The smallest flightless bird is the Inaccessible Island rail. The largest flightless bird, which is also the largest living bird in general, is the common ostrich.
Lyall's wren or the Stephens Island wren was a small, flightless passerine belonging to the family Acanthisittidae, the New Zealand wrens. Now extinct, 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, 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 thereafter.
The South Island piopio also known as the New Zealand thrush, was a passerine bird of the family Oriolidae.
Pachyornis is an extinct genus of ratites from New Zealand which belonged to the moa family. Like all ratites it was a member of the order Struthioniformes. The Struthioniformes are flightless birds with a sternum without a keel. They also have a distinctive palate. This genus contains three species, and are part of the Anomalopteryginae or lesser moa subfamily. Pachyornis moa were the stoutest and most heavy-legged genus of the family, the most notable species being Pachyornis elephantopus - the heavy-footed moa. They were generally similar to the eastern moa or the broad-billed moa of the genus Euryapteryx, but differed in having a pointed bill and being more heavyset in general. At least one species is assumed to have had a crest of long feathers on its head. The species became rapidly extinct following human colonization of New Zealand, with the possible exception of P. australis, which may have already been extinct by then - although the most recent moa skeleton ever described is a partial skeleton of this species, radiocarbon dated to between 1396 and 1442.
The New Zealand rock wren is a small New Zealand wren endemic to the South Island of New Zealand. Its Māori names include pīwauwau, mātuitui, and tuke. Outside New Zealand it is sometimes known as the rockwren to distinguish it from the unrelated rock wren of North America.
The long-billed wren is an extinct species of New Zealand wren formerly 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.
The New Zealand bittern is an extinct and enigmatic species of heron in the family Ardeidae. It was endemic to New Zealand and was last recorded alive in the 1890s.
Paleontology or palaeontology is the study of prehistoric life forms on Earth through the examination of plant and animal fossils. This includes the study of body fossils, tracks (ichnites), burrows, cast-off parts, fossilised feces (coprolites), palynomorphs and chemical residues. Because humans have encountered fossils for millennia, paleontology has a long history both before and after becoming formalized as a science. This article records significant discoveries and events related to paleontology that occurred or were published in the year 1988.
The long-legged bunting is an extinct flightless species of bunting. It was distinguishable by its long legs and short wings, and it inhabited Tenerife, one of the Canary Islands. It is one of the few flightless passerines known to science, all of which are now extinct.
The North Island giant moa is an extinct moa in the genus Dinornis, known in Māori as kuranui. Even though it might have walked with a lowered posture, standing upright, it would have been the tallest bird ever to exist, with a height estimated up to 3.6 metres (12 ft).
The broad-billed moa, stout-legged moa or coastal moa is an extinct species of moa that was endemic to New Zealand.
Anas chathamica, the Chatham duck or Chatham Island duck is an extinct species of duck which once lived in New Zealand's Chatham Islands in the south-west Pacific Ocean. It likely became extinct in about the 16th century because of hunting by humans.
Stout-legged wren is a common name referring to two species of extinct New Zealand wrens: the North Island stout-legged wren or Grant-Mackie's wren, and the South Island stout-legged wren or Yaldwyn's wren. These small birds were endemic to New Zealand and were previously included in the genus Pachyplichas.
