Phalacrocoracidae is a family of approximately 40 species of aquatic birds commonly known as cormorants and shags. Several different classifications of the family have been proposed, but in 2021 the International Ornithologists' Union (IOU) adopted a consensus taxonomy of seven genera. The great cormorant and the common shag are the only two species of the family commonly encountered in Britain and Ireland and "cormorant" and "shag" appellations have been later assigned to different species in the family somewhat haphazardly.
The black geese of the genus Branta are waterfowl belonging to the true geese and swans subfamily Anserinae. They occur in the northern coastal regions of the Palearctic and all over North America, migrating to more southernly coasts in winter, and as resident birds in the Hawaiian Islands. Alone in the Southern Hemisphere, a self-sustaining feral population derived from introduced Canada geese is also found in New Zealand.
The genus Aptenodytes contains two extant species of penguins collectively known as "the great penguins".
The genus Eudyptula contains two species of penguin, found in southern Australia, Tasmania, and New Zealand. They are commonly known as the little penguin, little blue penguin, or, in Australia, fairy penguin. In the language of the Māori people of New Zealand, little penguins are known as kororā.
Korora oliveri, also referred to as Oliver's penguin, is a genus and species of extinct penguin from the Waitakian Stage of New Zealand. It was relatively small and slender, similar in size to one of the larger crested penguins. The penguin was described by Brian Marples in 1952 from fossil material he collected in the Hakataramea Valley, in the Canterbury region of the South Island. The genus name Korora is the Māori term for the extant little penguin. The specific epithet honours Walter Oliver (1883–1957) a former director of the Dominion Museum.
Archaeospheniscus is an extinct genus of large penguins. It currently contains three species, known from somewhat fragmentary remains. A. wimani, the smallest species, was found in Middle or Late Eocene strata of the La Meseta Formation on Seymour Island, Antarctica, whereas the other two, about the size of a modern emperor penguin, are known from bones recovered from the Late Oligocene Kokoamu Greensand Formation at Duntroon, New Zealand.
Palaeeudyptinae, the giant penguins, is a paraphyletic subfamily of prehistoric penguins. It includes several genera of medium-sized to very large species, such as Icadyptes salasi, Palaeeudyptes marplesi, Anthropornis nordenskjoeldi, and Pachydyptes ponderosus. Icadyptes reached 1.5 m in height, while members of Palaeeudyptes and Anthropornis grew even taller and were some of the largest penguins to have ever existed. The massive P. ponderosus may have weighed at least as much as an adult human.
Pygoscelis tyreei, also referred to as Tyree's penguin, is an extinct species of penguin from New Zealand. It was slightly smaller than the extant gentoo penguin, standing 70 to 80 cm high. Of Late Pliocene age, it is known only from fossil remains collected from Motunau Beach, North Canterbury.
Aptenodytes ridgeni, also referred to as Ridgen's penguin, is an extinct species of penguin from the Pliocene of New Zealand. It was intermediate in size between its living congeners, standing an estimated 90–100 cm tall. The remains were first found in 1968 on a Canterbury region beach by 11-year-old schoolboy Alan Ridgen.
Archaeospheniscus lowei is the type species of the extinct penguin genus Archaeospheniscus. It stood approximately 85–115 cm high, between a modern king penguin and an emperor penguin in size. It is known from bones of a single individual and possibly some additional material such as the OM C.47.27 femur, all recovered from the Late Oligocene Kokoamu Greensand Formation at Duntroon, New Zealand.
Archaeospheniscus lopdelli was the largest species of the extinct penguin genus Archaeospheniscus, standing about 90–120 cm (35–47 in) high, or somewhat less than the extant emperor penguin. It is only known from bones of a single individual which was found in the Late Oligocene Kokoamu Greensand Formation at Duntroon, New Zealand. Bones apparently belonging to this species are now also known from the Late Eocene La Meseta Formation on Seymour Island, Antarctica.
Marples' penguin was a large species of the extinct penguin genus Palaeeudyptes.
Manu antiquus is a species of extinct bird of uncertain affinities from the Oligocene of New Zealand. It was described by Brian Marples in 1946 from fossil material found near Duntroon, north Otago, in the South Island. Marples suggested that it might be an early albatross; subsequent researchers have speculated that it could be a pelagornithid; however, its affinities remain uncertain. The genus name Manu is Māori for “bird”; the specific epithet antiquus is Latin for “old” or “ancient”.
Australornis is a genus of extinct seabird discovered in New Zealand. It lived in the Paleocene epoch, 60.5 to 61.6 million years ago (Ma). The type species name originates from australis, Latin for "southern", and ornis, the Greek word for "bird", and lovei commemorates Leigh Love, an amateur paleontologist who discovered it.
Manuherikia is a genus of extinct species of ducks from the Miocene of New Zealand. It was described from fossil material of the Saint Bathans Fauna, in the lower Bannockburn Formation of the Manuherikia Group, found by the Manuherikia River in the Central Otago region of the South Island. The genus name comes from the name of the geological formation in which the fossils were found and, ultimately, from the Manuherikia River and its valley.
Duntroonornis parvus, also referred to as the Duntroon penguin, is a genus and species of extinct penguin from the Late Oligocene of New Zealand. The penguin was relatively small, similar in size to the Fiordland crested penguin. It was described by Brian Marples in 1952 from fossil material collected near Duntroon, from the Kokoamu Greensand Formation, near the border between the Canterbury and Otago regions of the South Island. Fossils found at the Hakataramea Valley may also be referrable to this species. The genus name Duntroonornis means "Duntroon bird". The specific epithet is the Latin parvus ("small").
Platydyptes is a genus of extinct penguins from the Late Oligocene to Early Miocene of New Zealand. It was created by Brian Marples in 1952 and contains three relatively large species, all of which were described from the north Otago to south Canterbury region in the South Island. The genus name Platydyptes combines the Greek platys, alluding to the shape of the humerus, with dyptes ("diver").
Tereingaornis moisleyi, also referred to as Moisley's penguin, is a genus and species of extinct penguin from the Middle Pliocene of New Zealand. It was slightly smaller than the extant Fiordland crested penguin. It was described by Ron Scarlett in 1983 from fossil material found by William Moisley near Te Reinga Falls on the Wairoa River, in the Hawke's Bay Region of the North Island. Another specimen was found later at Waihi Beach, Hawera, on the South Taranaki Bight. The genus name Tereingaornis combines the name of the type locality with the Greek ornis ("bird"); the specific epithet honours the discoverer of the fossil.
Pleistorallus flemingi, also referred to as Fleming's rail, is a genus and species of extinct bird in the rail family from the Middle Pleistocene of New Zealand. It was a large and stout rail about the same size as the extant takahē. It was described by Trevor Worthy in 1997 from fossil material found in coastal deposits near Marton, in the Rangitikei District of the North Island. The genus name Pleistorallus refers to the Pleistocene age of the fossils; the specific epithet honours Charles Fleming (1916–1987) for his contributions to New Zealand ornithology and palaeontology.
Kerry-Jayne Wilson was a New Zealand biologist and lecturer in ecology at Lincoln University in the Faculty of Agriculture and Life Sciences.
