The Oxyurini are a tribe of the duck subfamily of birds, the Anatinae. It has been subject of considerable debate about its validity and circumscription. Some taxonomic authorities place the group in its own subfamily, the Oxyurinae. Most of its members have long, stiff tail feathers which are erected when the bird is at rest, and relatively large, swollen bills. Though their relationships are still enigmatic, they appear to be closer to swans and true geese than to the typical ducks. The highest diversity is found in the warmer parts of the Americas, but at least one species occurs in a major part of the world.
Owlet-nightjars are small crepuscular birds related to the nightjars and frogmouths. Most are native to New Guinea, but some species extend to Australia, the Moluccas, and New Caledonia. A flightless species from New Zealand is extinct. There is a single monotypic family Aegothelidae with the genus Aegotheles.
The Cracticinae, bellmagpies and allies, gathers together 12 species of mostly crow-like birds native to Australasia and nearby areas.
Alexandra is a town in the Central Otago district of the South Island of New Zealand. It is on the banks of the Clutha River, on State Highway 8, 188 kilometres (117 mi) by road from Dunedin and 33 kilometres (21 mi) south of Cromwell. The nearest towns to Alexandra via state highway 8 are Clyde seven kilometers to the northwest and Roxburgh forty kilometers to the south. State highway 85 also connects Alexandra to Omakau, Lauder, Oturehua, Ranfurly and on to Palmerston on the East Otago coast.
Metrosideros is a genus of approximately 60 trees, shrubs, and vines mostly found in the Pacific region in the family Myrtaceae. Most of the tree forms are small, but some are exceptionally large, the New Zealand species in particular. The name derives from the Ancient Greek metra or "heartwood" and sideron or "iron". Perhaps the best-known species are the pōhutukawa, northern and southern rātā of New Zealand, and ʻōhiʻa lehua, from the Hawaiian Islands.
The former gold and coal mining town of St Bathans, formerly named Dunstan Creek, lies deep in the heart of the Maniototo in New Zealand's Otago region. The settlement was a centre of the Otago Gold Rush, but mining has since long ceased and it is now a tranquil holiday retreat. The preservation of many of its historic buildings makes it one of the region's more picturesque tourist venues. St Bathans is well known for its scenic man-made lake with beautiful looking clay cliffs that attract many tourists. It is currently a camping spot, and swimming is allowed in the lake.
Palaelodus is an extinct genus of birds distantly related to flamingos. They were slender birds with long, thin legs and a long neck. Little is known about the shape of their skull or beak. Some paleontologists think Palaelodus was able to swim under water, chasing prey, but the morphology of their feet seems not very well adapted for diving. Rather, it is more likely that they were adapted to browsing for food while swimming or standing in shallow water.
Collocalia is a genus of swifts, containing some of the smaller species termed "swiftlets". Formerly a catch-all genus for these, a number of its former members are now normally placed in Aerodramus.
Landslip Hill is located on the boundary of Southland and Otago, in the South Island of New Zealand, between Tapanui and Pukerau. It is a debris flow feature associated with the Manuherikia Group of fluvial quartz sandstones. Geologists have described the fossil-bearing rocks as forming part of a sequence of "siliclastic fluvial deltaic sands, conglomerates and silty clays".
Nelepsittacus is a genus of extinct New Zealand parrots that is closely related to the genus Nestor. It consists of four species, of which three have been named so far. The species are all known from the early Miocene Saint Bathans Fauna from the Lower Bannockburn Formation in Otago in New Zealand.
Pelecanoides miokuaka is an extinct species of diving petrel of New Zealand. Described in 2007, it is known only from a single humerus bone that was discovered from early Miocene sediments of the Manuherikia Group.
Rupephaps taketake, also referred to as the Saint Bathans pigeon, is an extinct species of pigeon from the Miocene of New Zealand. It is the first species of columbid to be described from pre-Pliocene fossil deposits in the Australasian region.
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.
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.
Miotadorna sanctibathansi is an extinct tadornine duck from the Miocene of New Zealand. It was described from fossil material collected from 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 reflects the view of the describers that the bird is a Miocene shelduck similar to those in the genus Tadorna. The specific epithet refers to the fossil sites’ location in the vicinity of the historic gold mining town of Saint Bathans, of which it is a latinisation.
Matanas enrighti is an extinct duck from the Miocene of New Zealand. It was described from fossil material collected from a Saint Bathans Fauna site near Mata Creek, in the lower Bannockburn Formation of the Manuherikia Group, in the Manuherikia River valley in the Central Otago region of the South Island.
Pikaihao bartlei, also referred to as Bartle's bittern or the Saint Bathans bittern, is a genus and species of prehistoric small bittern from the Early Miocene of New Zealand. It was described in 2013 from fossil material found in the Saint Bathans Fauna of the Bannockburn Formation, at Home Hills Station in the Manuherikia River valley of Otago, South Island. It was a contemporary of the much larger Saint Bathans heron, remains of which have been found in the same sediments. The genus name Pikaihao comes from the Māori pi and kaihao (“fisherman”). The specific epithet honours Sandy Bartle, Curator of Birds at the Museum of New Zealand Te Papa Tongarewa from 1976 to 2009.
The Manuherikia Group is a fluvial-lacustrine sedimentary fill in the Central Otago area of New Zealand, at the site of the prehistoric Lake Manuherikia. The area consists of a valley and ridge topography, with a series of schist-greywacke mountains at roughly ninety degrees to each other. The Manuherika Group occurs in the current basins, and occasionally on the mountains themselves.
Lake Manuherikia was a prehistoric lake which once stretched over some 5,600 square kilometres (2,200 sq mi) in what is now inland Otago in the South Island of New Zealand. It covered much of the area now referred to as the Maniototo.
Foulden Maar, a fossil site near Middlemarch in Otago, New Zealand, formed in a volcanic eruption 23 million years ago. The resulting crater lake filled with diatomite, composed of layers of silica-shelled algae (diatoms) and exceptional fossils of plants, fishes, spiders and insects from the surrounding sub-tropical Miocene forest. As the only known maar of its kind in the Southern Hemisphere, it is one of New Zealand's pre-eminent fossil sites. A 2018 proposal to mine Foulden Maar for livestock-food additive has attracted significant public opposition.
