Kōkako
Kōkako are two species of forest bird in the genus ''Callaeas'' which are endemic to New Zealand, the endangered North Island kōkako (''Callaeas wilsoni'') and the presumed extinct South Island kōkako (''Callaeas cinereus''). They are both slate-grey with wattles and have black masks. They belong to a family containing five species of New Zealand wattlebirds, the other three being two species of tīeke (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. It is not closely related to the crow, but looks like one from a distance. Taxonomy The genus ''Callaeas'' was introduced in 1788 by the German naturalist Johann Reinhold Forster to accommodate a single species, the South Island kōkako, which is therefore the type ...

North Island Kōkako
The North Island kōkako (''Callaeas wilsoni'') is an endangered forest bird which is endemic (ecology), endemic to the North Island of New Zealand. It is grey in colour, with a small black mask. Adults have distinctive blue wattles. Because of its wattle, the bird is sometimes locally called the ''blue-wattled crow'', although it is not a corvid. The name "kōkako" comes from its vocalization. The song of the North Island kōkako has an almost human-like quality and can sound like its own name. Visual identification It is most immediately recognized by its unusual combination of elegant, dusky plumage and the vivid, fleshy blue wattles that hang prominently from either side of its beak. The overall coloration of the North Island kōkako is a soft, slate-grey to smoky blue hue that envelops its entire body. This rich, velvety grey is subtly shaded and largely uniform, though colouring is slightly darker on the wings and tail. The feathers have a silky appearance and a very f ...

South Island Kōkako
The South Island kōkako (''Callaeas cinereus'') is a forest bird endemic to the South Island and Stewart 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 - (and see note about search campaign below). In 2012 the Department of Conservation revised its criteria for species extinction to be consistent with international standards, meaning that "there is no reasonable doubt that the last individual has died", and only after "exhaustive surveys" of its known range have failed. After this change, the possible sighting of the bird near Reefton in 2007 was accepted. That decision was not unanimous: the panel chair didn't believe it, and doesn't believ ...

Callaeidae
Callaeidae (sometimes Callaeatidae) is a family of passerine birds endemic to New Zealand. It contains three genera, with five species in the family. One species, the huia, became extinct early in the 20th century, while the South Island kōkako is critically endangered and may be extinct. Although sometimes known as ''wattled crows'', they are not corvids and are only distantly related to crows - ''New Zealand wattlebirds'' is the informal name for this family used by the scientific community.Higgins, P.J. & J.M. Peter (eds) 2002. Handbook of Australian, New Zealand and Antarctic Birds. Volume 6: Pardalotes to Shrike-thrushes. Oxford University Press, Melbourne. Biology and evolution They are ground-dwelling songbirds, 26–38 cm in length. They inhabit dense forests, where they feed on insects. They have strong legs and featherless wattles behind the bill. Their wings are rounded and unusually weak, giving them very limited powers of flight. They are monogamous and m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 another 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 its pronounced sexual dimorphism in bill shape; 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 at both montane and lowland elevation ...

Saddleback (bird)
The saddlebacks or tīeke (Māori language, Māori) are two species of New Zealand birds of the family Callaeidae. Both are glossy black with a chestnut saddle. Their taxonomic family is also known as that of the (New Zealand) "wattlebirds" and includes the two species of kōkako, and the extinct huia. All members of the family Callaeidae have coloured fleshy Wattle (anatomy), wattles on either side of the beak; the saddlebacks' are a vivid red. Taxonomy The genus ''Philesturnus'' was introduced in 1832 by the French zoologist Isidore Geoffroy Saint-Hilaire to accommodate a single species, the South Island saddleback, which is therefore the type species of the genus. The name combines the honeyeater genus ''Philedon'' and the starling genus ''Sturnus''. 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 spec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bird
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. There are over 11,000 living species and they are split into 44 Order (biology), orders. More than half are passerine or "perching" birds. Birds have Bird wing, wings 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 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wattle (anatomy)
A wattle is a fleshy Caruncle (bird anatomy), caruncle hanging from various parts of the head or neck in several groups of birds and mammals. Caruncles in birds include those found on the face, wattles, dewlaps, Snood (anatomy), snoods, and earlobes. Wattles are generally paired structures but may occur as a single structure when it is sometimes known as a dewlap. Wattles are frequently organs of sexual dimorphism. In some birds, caruncles are erectile tissue and may or may not have a feather covering. Wattles are often such a striking Morphology (biology), morphological characteristic of animals that they feature in their common name. For example, the southern and northern cassowaries are known as the double-wattled and single-wattled cassowary, respectively, and a breed of domestic pig is known as the red wattle hog, Red Wattle. Birds Function In birds, wattles are often an ornament for courting Sexual selection, potential mates. Large wattles are correlated with high testos ...

Johann Reinhold Forster
Johann Reinhold Forster (; 22 October 1729 – 9 December 1798) was a German Reformed pastor and naturalist. Born in Tczew, Dirschau, Pomeranian Voivodeship (1466–1772), Pomeranian Voivodeship, Polish–Lithuanian Commonwealth (now Tczew, Poland), he attended school in Dirschau and Marienwerder before being admitted at the Joachimsthalsches Gymnasium in Berlin in 1745. Skilled in classical and biblical languages, he studied theology at the University of Halle. In 1753, he became a parson at a parish just south of Danzig. He married his cousin Justina Elisabeth Nicolai in 1754, and they had seven children; the oldest child was Georg Forster, George Forster, also known as Georg. In 1765, Forster was commissioned by the Russian government to inspect the new colonies on the Volga. Accompanied by George on the journey, he observed the conditions of the colonists and made scientific observations that were later read at the Russian Academy of Sciences.

Endangered Species
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching, invasive species, and climate change. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stitchbird
The stitchbird or hihi (''Notiomystis cincta'') is a honeyeater-like bird endemic to the North Island and adjacent offshore islands of New Zealand. Its evolutionary relationships have long puzzled ornithologists, but it is now classed as the only member of its own family, the Notiomystidae. It is rare, being extirpated everywhere except Little Barrier Island, but has been reintroduced to two other island sanctuaries and four locations on the North Island mainland.Adams (2019). Current population estimations for mature individuals in the wild are 2,500–3,400. In addition to hihi, the stitchbird is also known by a number of other Māori names, including: tihi, ihi, tihe, kotihe, tiora, tiheora, tioro, kotihe-wera (male only), hihi-paka (male only), hihi-matakiore (female only), mata-kiore (female only), tihe-kiore (female only). Taxonomy and systematics The stitchbird was originally described as a member of the primarily Australian and New Guinean honeyeater family Meliphag ...

Ancient Greek
Ancient Greek (, ; ) includes the forms of the Greek language used in ancient Greece and the classical antiquity, ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Greek Dark Ages, Dark Ages (), the Archaic Greece, Archaic or Homeric Greek, Homeric period (), and the Classical Greece, Classical period (). Ancient Greek was the language of Homer and of fifth-century Athens, fifth-century Athenian historians, playwrights, and Ancient Greek philosophy, philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Homeric Greek, Epic and Classical periods of the language, which are the best-attested periods and considered most typical of Ancient Greek. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
