A raven is any of several larger-bodied passerine bird species in the genus Corvus. These species do not form a single taxonomic group within the genus. There is no consistent distinction between crows and ravens; the two names are assigned to different species chiefly based on their size.
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 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 shore plover, also known as the shore dotterel, is a small plover endemic to New Zealand. Once found all around the New Zealand coast, it is now restricted to a few offshore islands. It is one of the world's rarest shorebirds: the population is roughly 250.
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.
The Chatham Islands rail, also known as the Chatham rail is an extinct flightless species of bird in the family Rallidae. It was endemic to Chatham, Mangere and Pitt Islands, in the Chatham archipelago of New Zealand. The Chatham Islands rail was first discovered on Mangere in 1871, and 26 specimens collected there are known from museum collections. Its Māori name was "mātirakahu".
The Chatham Islands bellbird or kōmako is an extinct species of bird in the family Meliphagidae. It was endemic to the Chatham Islands.
Xenicus is a genus of birds in the family Acanthisittidae. It contains New Zealand wrens.
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.
The New Zealand parrot family, Strigopidae, consists of at least three genera of parrots – Nestor, Strigops, the fossil Nelepsittacus, and probably the fossil Heracles. The genus Nestor consists of the kea, kākā, Norfolk kākā and Chatham kākā, while the genus Strigops contains the iconic kākāpō. All extant species are endemic to New Zealand. The species of the genus Nelepsittacus were endemics of the main islands, while the two extinct species of the genus Nestor were found at the nearby oceanic islands such as Chatham Island of New Zealand, and Norfolk Island and adjacent Phillip Island.
The Chatham kākā or Chatham Island kākā is an extinct parrot species previously found on the Chatham Islands, New Zealand. The first individuals were thought to belong to the New Zealand kākā, but detailed examination of the subfossil bones showed that they actually belong to a separate endemic species. The species became extinct within the first 150 years of the arrival of the Polynesians around 1500, long before any European settlers. No skins or descriptions are available.
The broad-billed moa, stout-legged moa or coastal moa is an extinct species of moa that was endemic to New Zealand.
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.
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.
The St Bathans fauna is found in the lower Bannockburn Formation of the Manuherikia Group of Central Otago, in the South Island of New Zealand. It comprises a suite of fossilised prehistoric animals from the late Early Miocene (Altonian) period, with an age range of 19–16 million years ago.
