Kōkako
Kōkako (''Callaeas'') are two species of endangered forest birds which are endemic to New Zealand, the North Island kōkako (''Callaeas wilsoni'') and the presumably extinct South Island kōkako (''Callaeas cinereus''). They are both slate-grey with wattles and have black masks. They belong to a genus containing five known species of New Zealand wattlebird, the other three being two species of tieke (saddleback) and the extinct huia. Previously widespread, kōkako populations throughout New Zealand have been decimated by the predations of mammalian invasive species such as possums, stoats, cats and rats, and their range has contracted significantly. In the past this bird was called the New Zealand crow; however, it is not a crow at all, but it looks like one from a distance. The spelling ''kokako'' (without a macron) is common in New Zealand English. Taxonomy The kōkako appears to be a remnant of an early expansion of passerines in New Zealand and is one of five species of ...

South Island Kōkako
The South Island kōkako (''Callaeas cinereus'') is a possibly extinct forest bird endemic to the South Island of New Zealand. Unlike its close relative, the North Island kōkako (''C. wilsoni''), it has largely orange wattles, with only a small patch of blue at the base, and was also known as the orange-wattled crow (though it was not a corvid). The last accepted sighting in 2007 was the first considered genuine since 1967, although there have been several other unauthenticated reports. Taxonomy The kōkako was first described by German naturalist Johann Friedrich Gmelin in 1788 as ''Glaucopis cinerea,'' from the Latin ''cinereus'' ("grey"). For some time the North Island and South Island birds were considered subspecies of ''Callaeas cinerea'', but since 2001 North Island birds have been officially recognised as ''C. wilsoni'', and genetic evidence confirms their difference. Although the genus ''Callaeas'' is masculine, the species epithet ''cinerea'' is not masculinised to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North Island Kōkako
The North Island kōkako (''Callaeas wilsoni'') is an endangered forest bird which is endemic to the North Island of New Zealand. It is grey in colour, with a small black mask. It has blue wattles (although this colour develops with age: in the young of this bird they are actually coloured a light pink). Because of its wattle, the bird is sometimes locally called the ''blue-wattled crow'', although it is not a corvid. Threats and conservation In the early 1900s the North Island kōkako was common in forests throughout the North Island and its offshore islands. Primary causes of kōkako decline were forest clearance by settlers and the introduction of predators such as rats, stoats and possums. Unlike many of New Zealand's most vulnerable birds, kōkako survive in low numbers in several North Island native forests. However, research has shown that female kōkako are particularly at risk of predation as they carry out all incubation and brooding throughout a prolonged (50-day) ne ...

Saddleback (bird)
The saddlebacks ( mi, tīeke) are two species of New Zealand bird of the family Callaeidae. Both are glossy black with a chestnut saddle. Its taxonomic family is also known as that of the (New Zealand) "wattlebirds" and includes the two subspecies of the kōkako (the extant North Island kōkako monitored on island sanctuaries, and the extinct South Island kōkako) as well as the extinct huia. All members of the family Callaeidae have coloured fleshy appendages on either side of the beak, known as wattles; Saddlebacks' wattles are a vivid red. Taxonomy The saddleback's common name derives from the demarcated brown plumage on its back, which resembles a saddle. The Māori name, , is onomatopoeic and comes from one of the species' calls: "ti-e-ke-ke-ke-ke". There are two species: * North Island saddleback — ''Philesturnus rufusater'' * South Island saddleback — ''Philesturnus carunculatus'' The saddlebacks appear to be a remnant of an early expansion of passerines in New Ze ...

Huia
The huia ( ; ; ''Heteralocha acutirostris'') is an extinct species of New Zealand wattlebird, endemic to the North Island of New Zealand. The last confirmed sighting of a huia was in 1907, although there was a credible sighting in 1924. It was already a rare bird before the arrival of Europeans, confined to the Ruahine, Tararua, Rimutaka and Kaimanawa mountain ranges in the south-east of the North Island. It was remarkable for having the most pronounced sexual dimorphism in bill shape of any bird species in the world. The female's beak was long, thin and arched downward, while the male's was short and stout, like that of a crow. Males were long, while females were larger at . The sexes were otherwise similar, with orange wattles and deep metallic, bluish-black plumage with a greenish iridescence on the upper surface, especially about the head. The tail feathers were unique among New Zealand birds in having a broad white band across the tips. The birds lived in forests ...

Birds Of New Zealand
''For a list of birds in New Zealand, see List of birds of New Zealand.'' The birds of New Zealand evolved into an avifauna that included many endemic species found in no other country. As an island archipelago, New Zealand accumulated bird diversity, and when Captain James Cook arrived in the 1770s he noted that the bird song was deafening. The mix includes species with unusual biology such as the kākāpō which is the world's only flightless, nocturnal parrot which also exhibits competitive display breeding using leks. There are also many species that are similar to neighbouring land areas. A process of colonisation, speciation and extinction has been at play over many millions of years, including recent times. Some species have arrived in human recorded history while others arrived before but are little changed. History after human settlement When humans arrived in New Zealand about 700 years ago the environment changed quickly. Several species were hunted to extinction, ...

New Zealand Fifty-dollar Note
The New Zealand fifty-dollar note is a New Zealand banknote. It is issued by the Reserve Bank of New Zealand and since 1999 has been a polymer banknote. It was first issued in 1983. The note originally had an image of Queen Elizabeth II on the front; since 1992 it has had an image of Sir Āpirana Ngata. Design There have been seven different series of New Zealand banknotes, and the fifty-dollar note was introduced with the fourth series of banknotes, to fill the gap between the twenty-dollar and one-hundred-dollar notes. Fourth series (1983–1991) The first issue had a portrait of Elizabeth II on the front and used orange colouring. The back of the note featured a morepork or ruru, New Zealand's only extant native owl. The owl was perched on a pohutukawa, a tree found on the New Zealand coast and often referred to as the "New Zealand Christmas tree". The watermark was of Captain James Cook. Fifth series (1991–1999) New Zealand's banknotes were completely re-designed in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johann Reinhold Forster
Johann Reinhold Forster (22 October 1729 – 9 December 1798) was a German Continental Reformed church, Reformed (Calvinist) pastor and natural history, naturalist of partially Scottish descent who made contributions to the early ornithology of Europe and North America. He is best known as the naturalist on James Cook's Second voyage of James Cook, second Pacific voyage, where he was accompanied by his son Georg Forster. These expeditions promoted the career of Johann Reinhold Forster and the findings became the bedrock of colonial professionalism and helped set the stage for the future development of anthropology and ethnology. They also laid the framework for general concern about the impact that alteration of the physical environment for European economic expansion would have on exotic societies. Biography Forster's family originated in the Lord Forrester, Lords Forrester in Scotland from where his great-grandfather had emigrated after losing most of his property during the ...

Prumnopitys Taxifolia
''Prumnopitys taxifolia'', the mataī ( mi, mataī) or black pine, is an endemic New Zealand coniferous tree that grows on the North Island and South Island. It also occurs on Stewart Island/Rakiura (47 °S) but is uncommon there. It grows up to 40 m high, with a trunk up to 2 m diameter. The leaves are linear to sickle-shaped, 10–15 mm long and 1.5–2 mm broad. The seed cones are highly modified, reduced to a central stem 3–4 cm long bearing 1-6 scales, each scale maturing berry-like, 10–15 mm long, violet-purple with a soft edible pulp covering the single seed. The seeds are dispersed by the New Zealand pigeon (kererū), which eats the 'berries' and passes the seeds in its droppings. Classification The scientific name ''taxifolia'' derives from the resemblance of the leaves to those of the yew (''Taxus''). In the past the species, like the other species of ''Prumnopitys'', was often included in ''Podocarpus''; in this species under the name ''Podo ...

Podocarps
Podocarpaceae is a large family of mainly Southern Hemisphere conifers, known in English as podocarps, comprising about 156 species of evergreen trees and shrubs.James E. Eckenwalder. 2009. ''Conifers of the World''. Portland, Oregon: Timber Press. . It contains 19 genera if ''Phyllocladus'' is included and ''Manoao'' and ''Sundacarpus'' are recognized. The family is a classic member of the Antarctic flora, with its main centres of diversity in Australasia, particularly New Caledonia, Tasmania, and New Zealand, and to a slightly lesser extent Malesia and South America (primarily in the Andes Mountains). Several genera extend north of the equator into Indochina and the Philippines. ''Podocarpus'' reaches as far north as southern Japan and southern China in Asia, and Mexico in the Americas, and ''Nageia'' into southern China and southern India. Two genera also occur in sub-Saharan Africa, the widespread ''Podocarpus'' and the endemic '' Afrocarpus''. ''Parasitaxus usta'' is un ...

Rimu
''Dacrydium cupressinum'', commonly known as rimu, is a large evergreen coniferous tree endemic to the forests of New Zealand. It is a member of the southern conifer group, the podocarps. The Māori name ''rimu'' comes from the Polynesian term ''limu'' which the tree's foliage were reminded of, ultimately from Proto-Austronesian *''limut'' meaning "moss". The former name "red pine" has fallen out of common use. Distribution Rimu grows throughout New Zealand, in the North Island, South Island and Stewart Island/Rakiura. This species is common in lowland and montane forest. Although the largest concentration of trees is now found on the West Coast of the South Island, the biggest trees tend to be in mixed podocarp forest near Taupō (e.g., Pureora, Waihaha, and Whirinaki Forests). A typical North Island habitat is in the Hamilton Ecological District, where '' Fuscospora truncata'' and rimu form the overstory. Associate ferns on the forest floor are ''Blechnum discolor'', ''B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
