New Zealand Musk Duck
The New Zealand musk duck (''Biziura delautouri''), also known as de Lautour's duck, is an extinct stiff-tailed duck native to New Zealand. It is only known from subfossil bones. Its closest relative was the living Australian musk duck ''Biziura lobata'', with which it has sometimes been combined. History The first discovery of the fossil remains of the duck, a single tarsometatarsus associated with large numbers of moa bones, was made at Enfield, near Oamaru in the South Island of New Zealand. It was first described, as ''Biziura delautouri'', in March 1892 by Dr Henry Forbes, the director of the Canterbury Museum in Christchurch at the time, who named it after Dr H. de Lautour of Oamaru, who helped acquire the specimen. Another paper by Forbes later used the spelling ''Biziura lautouri''; but the earlier name has priority. Subsequently, additional material was obtained from Marfells Beach, adjacent to Lake Grassmere at the north-eastern end of the South Island, and described ...

Henry Ogg Forbes
Henry Ogg Forbes LLD (30 January 1851 – 27 October 1932) was a Scottish explorer, ornithologist, and botanist. He also described a new species of spider, '' Thomisus decipiens''. Biography Forbes was the son of Rev Alexander Forbes M.A. (1821–1897),Ewing, William ''Annals of the Free Church'' and his wife Mary ''née'' Ogg (1820–1862), and was born at Drumblade, Huntly, Aberdeenshire. Henry was educated at Aberdeen Grammar School, he then studied Medicine at the University of Aberdeen and the University of Edinburgh, An eye injury forced him to abandon his studies and he did not graduate. From 1875 he began collecting scientific samples: firstly in Portugal and from 1878 to 1884 he made extensive collections in Indonesia. Forbes was active primarily in the Moluccas, Sumatra and New Guinea. His unusual tasks there also included tracking down the murderers of Captain J. C. Craig on Joannet Island in his temporary capacity as a government agent. In 1887 he was appointed met ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ron Scarlett
Ronald Jack Scarlett (22 March 1911 – 9 July 2002) was a New Zealand paleozoologist. Early life and family Scarlett was born at Stoke, near Nelson, on 22 March 1911 to Walter Andrew Scarlett and Lilian Elsie (née Cresswell). He was the oldest child of four brothers and four sisters. His father was an impoverished sawyer and so the family was forced to move around the upper South Island to find work in sawmills. Ron Scarlett attended six primary schools until he began to work at age 14. He had jobs on farms, in a sawmill, as a labourer, as golf greenkeeper, as gardener, as goldminer and later as trucker for a coalmine. During World War II, he spent some time as a conscientious objector in the Hanmer Springs Conscientious Objectors camp. Scientific career After he joined the staff of the Canterbury Museum in 1952 he became one of the most prolific osteologists of New Zealand. Scarlett became notable for his excavations over many decades on several paleontological deposits on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extinct Birds Of New Zealand
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dodos, m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Late Quaternary Prehistoric Birds
Late Quaternary prehistoric birds are avian taxa that became extinct during the Late Quaternary – the Holocene or Late Pleistocene – and before recorded history, or more precisely, before they could be studied alive by ornithological science. They became extinct before the period of global scientific exploration that started in the late 15th century. In other words, this list basically deals with extinctions between 40,000 BC and 1500 AD. For the purposes of this article, a "bird" is any member of the clade Neornithes, that is, any descendant of the most recent common ancestor of all currently living birds. The birds are known from their remains, which are subfossil (not fossilized, or not completely fossilized). Some are also known from folk memory, as in the case of Haast's eagle in New Zealand. As the remains are not completely fossilized, they may yield organic material for molecular analyses to provide additional clues for resolving their taxonomic affil ...

Taxa Named By Henry Ogg Forbes
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Described In 1892
Birds are a group of warm-blooded vertebrates constituting the class (biology), class Aves (), characterised by feathers, toothless beaked jaws, the Oviparity, laying of Eggshell, hard-shelled eggs, a high Metabolism, metabolic rate, a four-chambered heart, and a strong yet lightweight Bird skeleton, skeleton. Birds live worldwide and range in size from the bee hummingbird to the Common ostrich, ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the Flightless bird, loss of flight in some birds, including ratites, penguins, and diverse endemism, endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oxyurinae
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. Their habitus resembles a freshwater diving duck, particularly when moving on dry land. Their legs are set far back, making them awkward walkers, so they rarely leave the water. When at rest, their tails are a notable difference, and in the water they often swim very deep-set. Their unusual courtship displays involve drumming noises from inflatable throat sacs, head t ...

Ducks
Duck is the common name for numerous species of waterfowl in the family Anatidae. Ducks are generally smaller and shorter-necked than swans and geese, which are members of the same family. Divided among several subfamilies, they are a form taxon; they do not represent a monophyletic group (the group of all descendants of a single common ancestral species), since swans and geese are not considered ducks. Ducks are mostly aquatic birds, and may be found in both fresh water and sea water. Ducks are sometimes confused with several types of unrelated water birds with similar forms, such as loons or divers, grebes, gallinules and coots. Etymology The word ''duck'' comes from Old English 'diver', a derivative of the verb 'to duck, bend down low as if to get under something, or dive', because of the way many species in the dabbling duck group feed by upending; compare with Dutch and German 'to dive'. This word replaced Old English / 'duck', possibly to avoid confusion with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kerry-Jayne Wilson
Kerry-Jayne Wilson (6 March 1949 – 29 March 2022) was a New Zealand biologist and lecturer in ecology at Lincoln University in the Faculty of Agriculture and Life Sciences. Work As an undergraduate, Wilson spent the summer of 1969–1970 in the Snares Islands, working as an assistant to the Australian ornithologist and photographer John Warham. She was struck by the huge numbers of sooty shearwaters ('' Puffinus griseus''), penguins, petrels, and prions, and seabirds later became her research focus. She earned a Master of Science degree at the University of Canterbury, and was appointed a faculty member at Lincoln College (now Lincoln University) in 1986. Wilson worked for over 40 years on different conservation projects in New Zealand, with a focus on its avifauna. Most of her field research on seabirds was conducted in New Zealand, the Chathams, the sub-Antarctic Islands, and Antarctica, but she also worked in Mongolia, Malaysia, Newfoundland, Indonesia and the Cook Isla ...

Trevor Worthy
Trevor Henry Worthy (born 3 January 1957) is an Australia-based paleozoologist from New Zealand, known for his research on moa and other extinct vertebrates. Biography Worthy grew up in Broadwood, Northland, and went to Whangarei Boys' High School. He began his career as a largely self-taught palaeontologist, after becoming interested in fossils through caving. Worthy completed his BSc and MSc at the University of Waikato, then did a second Master's degree at Victoria University of Wellington. In 1987, Worthy described three new leiopelmatid frog species from cave subfossils: the Aurora frog (''Leiopelma auroraensis''), Markham's frog (''Leiopelma markhami''), and the Waitomo frog (''Leiopelma waitomoensis''). In the 1990s, he discovered several fossil bird species new to science, including the long-billed wren (''Dendroscansor decurvirostris'') in 1991, Scarlett's shearwater (''Puffinus spelaeus'') in 1991, and the Niue night heron (''Nycticorax kalavikai'') in 1995.

Sexual Dimorphism
Sexual dimorphism is the condition where the sexes of the same animal and/or plant species exhibit different morphological characteristics, particularly characteristics not directly involved in reproduction. The condition occurs in most animals and some plants. Differences may include secondary sex characteristics, size, weight, colour, markings, or behavioural or cognitive traits. These differences may be subtle or exaggerated and may be subjected to sexual selection and natural selection. The opposite of dimorphism is ''monomorphism'', which is when both biological sexes are phenotypically indistinguishable from each other. Overview Ornamentation and coloration Common and easily identified types of dimorphism consist of ornamentation and coloration, though not always apparent. A difference in coloration of sexes within a given species is called sexual dichromatism, which is commonly seen in many species of birds and reptiles. Sexual selection leads to the exaggerated dim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Poukawa
Lake Poukawa is a small shallow hardwater lake in the Hawke's Bay Region, North Island, New Zealand. It is located about 20 km south-west of Hastings, New Zealand, close to the settlement of Te Hauke. It is the largest lake lying within a peatland in the active tectonic Poukawa depression (or Poukawa Basin), between the Raukawa Range and Kaokaoroa Range of central Hawke's Bay. Its maximal depth is less than one metre and its diameter is ca. 1.5 km. It was deeper in the past (about 2.5 metre) but it was artificially drained after the 1931 Hawke's Bay earthquake. Lake Poukawa became a well-known paleontological site in 1956 when paleontologist Russell Price began with his excavations in the lacustrine deposits. Lake Poukawa had a species rich Pleistocene/Holocene waterfowl fauna. More than 13,400 anatid bones were unearthed at this site since 1956. Extinct birds found at Lake Poukawa include Biziura delautouri, Oxyura vantetsi, Mergus australis, Chenonetta finschi, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
