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. [1]
The species was formerly placed in a monotypic genus Pachyanas. However, analysis of mitochondrial DNA extracted from subfossil remains [2] showed that the Chatham duck was not, in fact, closely related to shelducks but instead belongs in the genus Anas : the dabbling ducks. Its closest living relatives appear to be the Auckland teal, Campbell teal and the brown teal from New Zealand.
It was described by Walter Oliver (as a "stoutly built duck") from bird bones in the collection of the Canterbury Museum in 1955 in the second edition of his work New Zealand Birds. [3] Some authors have suggested that the Chatham duck was flightless; [4] however, comparison of Chatham duck wing bones with those from living ducks indicates no disproportional reduction in wing length. [2]
Anas is a genus of dabbling ducks. It includes the pintails, most teals, and the mallard and its close relatives. It formerly included additional species but following the publication of a molecular phylogenetic study in 2009 the genus was split into four separate genera. The genus now contains 31 living species. The name Anas is the Latin for "duck".
The New Zealand merganser, also known as Auckland merganser or Auckland Islands merganser, was a typical merganser which is now extinct.
The New Zealand bellbird, also known by its Māori names korimako, makomako, and kōmako, is a passerine bird endemic to New Zealand. It has greenish colouration and is the only living member of the genus Anthornis. The bellbird forms a significant component of the famed New Zealand dawn chorus of bird song that was much noted by early European settlers. The explorer Captain Cook wrote of its song "it seemed to be like small bells most exquisitely tuned". The species is common across much of New Zealand and its offshore islands as well as the Auckland Islands.
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 piopio or turnagras are an extinct genus of passerine birds in the family Oriolidae, that were endemic to New Zealand. Sometimes described as New Zealand thrushes, the piopio had only a coincidental, passing resemblance to the thrush family.
The bush moa, little bush moa, or lesser moa is an extinct species of moa from the family Emeidae.
The New Zealand raven was native to the North Island and South Island of New Zealand but has been extinct since the 16th century. There were two subspecies: the North Island raven and the South Island raven. Another closely related species, the Chatham raven, occurred on the Chatham Islands.
The eastern moa is an extinct species of moa that was endemic to New Zealand.
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.
The Chatham bellbird is an extinct species of bird in the family Meliphagidae. It was endemic to the Chatham Islands.
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.
The New Zealand stiff-tailed duck is an extinct duck species from New Zealand which is known only from subfossil remains. It was first described as a distinct species by Trevor H. Worthy in 2005.
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 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 snipe-rail is an extinct flightless rail endemic to the North Island of New Zealand. The species' name is derived from the Karamu Cave 21 kilometres (13 mi) from Hamilton where the holotype was discovered in 1954.
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.
