The bush moa, little bush moa, or lesser moa (Anomalopteryx didiformis) is an extinct species of moa from the family Emeidae (lesser moa).
The bush moa was first scientifically described as Dinornis didiformis by Richard Owen in 1844. He chose the specific name didiformis because of the apparent similarity in the shape and size of the tarsometatarsus to that of the dodo (then Didus ineptus). [4]
It was the smallest known species of moa, [5] only slightly taller than a turkey. A slender bird, it weighed around 30 kilograms (66 lb). [6] As with all moa, they have a sternum but no keel. They also have a distinctive palate. [7] [ full citation needed ] It inhabited much of the North Island and small sections of the South Island of New Zealand. Its habitat was dense lowland conifer, broad-leafed southern beech forests and scrubland. [6] [7] It possessed a sturdy, sharp-edged beak, suggesting that its diet was made up of twigs and other tough plant material. [6] [5]
Native predators included the Haast's eagle and Eyles' harrier. [6] The species went extinct alongside other native New Zealand wildlife around 500-600 years ago, following the arrival and proliferation of the Maori people in New Zealand (who called them "moariki"), [1] as well as the introduction of Polynesian dogs. [6]
The most complete remains, a partially articulated skeleton with substantial mummified tissue and feathers were discovered in 1980 in Lake Echo Valley, east of Te Anau, Southland. [8] It is now in the Southland Museum and Art Gallery, in Invercargill. Anomalopteryx fossils made up the bulk of moa fossils discovered in a swamp in 1912 in Clevedon. [9]
Scientists at Harvard University assembled the first nearly complete genome of the species from toe bones, [10] [11] thus bringing the species a step closer to being "resurrected" in the future by using the emu as a proxy. [10]
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.
The New Zealand merganser, also known as Auckland merganser or Auckland Islands merganser, was a typical merganser which is now extinct.
The adzebills, genus Aptornis, were two closely related bird species, the North Island adzebill,, and the South Island adzebill,, of the extinct family Aptornithidae. The family was endemic to New Zealand. A tentative fossil species,, is known from the Miocene Saint Bathans fauna.
The upland moa is an extinct species of moa that was endemic to New Zealand. It is a ratite, a grouping of flightless birds with no keel on the sternum. It was the last moa species to become extinct, vanishing around 1500 CE, and was predominantly found in alpine and sub-alpine environments.
The giant moa (Dinornis) is an extinct genus of birds belonging to the moa family. As with other moa, it was a member of the order Dinornithiformes. It was endemic to New Zealand. Two species of Dinornis are considered valid, the North Island giant moa and the South Island giant moa. In addition, two further species have been suggested based on distinct DNA lineages.
The eastern moa is an extinct species of moa that was endemic to New Zealand.
The New Zealand quail, or koreke in Māori, is an extinct quail species endemic to New Zealand. The male and female were similar, except the female was lighter. The first scientist to describe it was Sir Joseph Banks when he visited New Zealand on James Cook's first voyage. Terrestrial and temperate, this species inhabited lowland tussock grassland and open fernlands. The first specimen to be obtained by a European was collected in 1827 by Jean René Constant Quoy and Joseph Paul Gaimard on Dumont D'Urville's voyage. It most likely went extinct due to diseases from introduced game birds.
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.
Finsch's duck was a large terrestrial species of duck formerly endemic to New Zealand. The species was possibly once the most common duck in New Zealand, a supposition based on the frequency of its fossils in bone deposits.
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.
Forbes's snipe is an extinct species of New Zealand snipe formerly endemic to the Chatham Islands. It was the larger of two species found there, the smaller being the surviving Chatham snipe. It was never seen alive by scientists and is known only from fossil material collected on the islands. Why it became extinct while its smaller relative survived is a mystery, as is the exact timing of its extinction, although it may have survived, unnoticed, until the 15th century.
Scarlett's duck is an extinct duck species from New Zealand which was closely related to the Australian pink-eared duck. The scientific name commemorates the late New Zealand ornithologist and palaeontologist Ron Scarlett who discovered the holotype in 1941. However, previously undescribed bones of the species found in 1903 were rediscovered in the Otago Museum in 1998. At least 32 fossil remains from deposits in Pyramid Valley, at Ngāpara in the South Island, and at Lake Poukawa in the North Island are in museum collections.
The heavy-footed moa is a species of moa from the lesser moa family. The heavy-footed moa was widespread only in the South Island of New Zealand, and its habitat was the lowlands. The moa were ratites, flightless birds with a sternum without a keel. They also have a distinctive palate. The origin of these birds is becoming clearer as it is now believed that early ancestors of these birds were able to fly and flew to the southern areas in which they have been found.
The North Island giant moa is an extinct moa in the genus Dinornis. 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.
The South Island giant moa is an extinct species of moa in the genus Dinornis. It was the tallest-known bird species to walk the Earth, exceeded in weight only by the heavier but shorter elephant bird of Madagascar.
The broad-billed moa, stout-legged moa or coastal moa is an extinct species of moa that was endemic to New Zealand.
Mantell's moa also known as Mappin's moa is an extinct species of moa from the North Island of New Zealand. Its habitat was the lowlands. The moa were ratites, flightless birds with a sternum without a keel. They also have a distinctive palate. The origin of the ratites is becoming clearer as it is now believed that early ancestors of these birds were able to fly and flew to the southern areas that they have been found in.
The New Zealand goose is a bird of the extinct genus Cnemiornis of the family Anatidae, subfamily Anserinae. The genus, endemic to New Zealand, consisted of two species: the North Island goose, C. gracilis and the South Island goose C. calcitrans.
Scarlett's shearwater is an extinct species of seabird in the petrel family Procellariidae. Its common name commemorates New Zealand palaeontologist Ron Scarlett, who recognised the bird's subfossil remains represented a distinct species.
The New Zealand musk duck, also known as de Lautour's duck, is an extinct stiff-tailed duck native to New Zealand. It is only known from subfossil bones. It was 10 percent larger than its closest living relative, the Australian musk duck Biziura lobata, with which it has sometimes been combined.
