Rockwarbler
The rockwarbler (''Origma solitaria''), is a bird in the family Acanthizidae. It is the only bird species endemic to the state of New South Wales in Australia. Taxonomy and systematics English artist and naturalist John Lewin described the rockwarbler in 1808. For many years it was the only member of its genus until genetic work showed that it was related to two species of mousewarblers from New Guinea. The rockwarbler diverged from the common ancestor of the other two species around 9 million years ago. Rockwarbler has been designated the official name by the International Ornithologists' Union (IOC). Common names also include cataract-bird, cave-bird, origma, rock-robin, and sandstone robin. A former common name, hanging dick, came about from its nest, which hangs suspended in a cave. It has no subspecies. Description The rockwarbler is in length and weighs around , with predominantly dark grey-brown plumage, darker wings and more red-brown underparts, cinnamon-tinged fac ...

Origma
''Origma'' is a genus of passerine birds in the family Acanthizidae. A molecular phylogenetic study of the scrubwrens and mouse-warblers published in 2018 led to a revision of the taxonomic classification. The genus ''Origma'' had previously contained only a single species, the rockwarbler, but in the reorganisation two additional species from the genus ''Crateroscelis'' were added. The rockwarbler diverged from the common ancestor of the other two species—the mousewarblers of New Guinea—around 9 million years ago. The genus contains three species: * Rockwarbler, ''Origma solitaria'' * Rusty mouse-warbler, ''Origma murina'' – previously placed in ''Crateroscelis'' * Mountain mouse-warbler The mountain mouse-warbler (''Origma robusta'') is a species of bird in the family Acanthizidae. It is found in Indonesia and Papua New Guinea, where its natural habitat is subtropical or tropical moist montane forests. This species was former ..., ''Origma robusta'' – previously ...

Acanthizidae
The Acanthizidae—known as Australian warblers—are a family of passerine birds which includes gerygones, the thornbills '' Acanthiza'', and the scrubwrens of '' Sericornis''. The Acanthizidae family consists of small to medium passerine birds, with a total length varying between . They have short rounded wings, slender bills, long legs, and a short tail. Most species have olive, grey, or brown plumage, although some have patches of a brighter yellow. The weebill is the smallest species of acanthizid, and the smallest Australian passerine; the largest is the pilotbird. Taxonomy and systematics Following the Sibley-Ahlquist taxonomy (1990) they were previously regarded as subfamily Acanthizinae within the family Pardalotidae. More recent molecular genetic studies do not support this arrangement. The Dasyornithidae (which include the bristlebirds) are variously seen either as subfamily Dasyornithinae within the family Acanthizidae or Pardalotidae or as own family (Schodde & Mas ...

Grey Butcherbird
The grey butcherbird (''Cracticus torquatus'') is a widely distributed species endemic to Australia. It occurs in a range of different habitats including arid, semi-arid and temperate zones. It is found across southern Australia, but is absent from the deserts of central Australia and the monsoon tropics of northern Australia. It has a characteristic "rollicking" birdsong. It appears to be adapting well to city living, and can be encountered in the suburbs of many Australian cities including Brisbane, Melbourne, and Sydney. The grey butcherbird preys on small vertebrates including other birds. Other birds in the same family include the Australian magpie, the currawongs, woodswallows and other members of the butcherbird genus ''Cracticus''. Taxonomy The grey butcherbird was first described by the English ornithologist John Latham in 1801 under the binomial name ''Lanius torquatus''. Closely related species include the silver-backed butcherbird (''Cracticus argenteus'') and th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Birds Of Australia
This article is one of a series providing information about endemism among birds in the world's various zoogeographic zones. For an overview of this subject see Endemism in birds. Patterns of endemism Family-level endemism is prominent in Australia. The Australasian biogeographic region has the highest number of endemic families of any zoogeographic region except the Neotropics, and many of these families are endemic to Australia itself — the country therefore stakes a strong claim to be the world's greatest hotspot of bird endemism. Australian endemic and near-endemic families The Australian endemic families are: * Emu (Dromaiidae), a well-known monotypic family; the emu is found in rural areas throughout the continent * Plains-wanderer (Pedionomidae), a monotypic family; plains-wanderer is restricted to arid inland areas in the southeast of Australia * Lyrebirds (Menuridae), two forest-dwelling species of southeast Australia * Scrub-birds (Atrichornithidae), two fore ...

Birds Of New South Wales
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the 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 loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. Birds ...

Wheat
Wheat is a grass widely cultivated for its seed, a cereal grain that is a worldwide staple food. The many species of wheat together make up the genus ''Triticum'' ; the most widely grown is common wheat (''T. aestivum''). The archaeological record suggests that wheat was first cultivated in the regions of the Fertile Crescent around 9600 BCE. Botanically, the wheat kernel is a type of fruit called a caryopsis. Wheat is grown on more land area than any other food crop (, 2014). World trade in wheat is greater than for all other crops combined. In 2020, world production of wheat was , making it the second most-produced cereal after maize. Since 1960, world production of wheat and other grain crops has tripled and is expected to grow further through the middle of the 21st century. Global demand for wheat is increasing due to the unique viscoelastic and adhesive properties of gluten proteins, which facilitate the production of processed foods, whose consumption is inc ...

Panic Grass
''Panicum'' (panicgrass) is a large genus of about 450 species of Poaceae, grasses native throughout the tropical regions of the world, with a few species extending into the northern temperate zone. They are often large, Annual plant, annual or Perennial plant, perennial grasses, growing to tall. The flowers are produced in a well-developed panicle often up to in length with numerous seeds, which are long and broad. The fruits are developed from a two-flowered spikelet. Only the upper floret of each spikelet is fertile; the lower floret is sterile or staminate. Both glumes are present and well developed. Australia has 29 native and 9 introduced species of ''Panicum''. Well-known ''Panicum'' species include ''Panicum miliaceum'' (proso millet) and ''Panicum virgatum'' (switchgrass). Selected species Formerly classified in this genus, according to The Plant List: Gallery File:Starr 020201-9001 Panicum antidotale.jpg, ''Panicum antidotale'' File:Panicum capillare NPS-1.j ...

Insectivore
A robber fly eating a hoverfly An insectivore is a carnivorous animal or plant that eats insects. An alternative term is entomophage, which can also refer to the human practice of eating insects. The first vertebrate insectivores were amphibians. When they evolved 400 million years ago, the first amphibians were piscivores, with numerous sharp conical teeth, much like a modern crocodile. The same tooth arrangement is however also suited for eating animals with exoskeletons, thus the ability to eat insects is an extension of piscivory. At one time, insectivorous mammals were scientifically classified in an order called Insectivora. This order is now abandoned, as not all insectivorous mammals are closely related. Most of the Insectivora taxa have been reclassified; those that have not yet been reclassified and found to be truly related to each other remain in the order Eulipotyphla. Although individually small, insects exist in enormous numbers. Insects make u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rufous Whistler
The rufous whistler (''Pachycephala rufiventris'') is a species of whistler found in New Caledonia and Australia. Predominantly a reddish-brown and grey bird, it makes up for its subdued plumage with its song-making ability. Like many other members of the Pachycephalidae, it has a variety of musical calls. Taxonomy and systematics The rufous whistler was originally described in the genus '' Sylvia'' by the English ornithologist John Latham in 1801. It was subsequently classified within the genera ''Turdus'', ''Laniarius'', and ''Lanius'' before being classified in its present genus, ''Pachycephala''. Alternate names for the rufous whistler include the rufous-bellied whistler and white-bellied whistler. The latter name should not be confused with the species of the same name, '' Pachycephala leucogastra''. Some authorities have considered the black-headed, drab, and cinnamon-breasted whistlers to be subspecies of the rufous whistler. Subspecies Five subspecies are recognized ...

Eastern Spinebill
The eastern spinebill (''Acanthorhynchus tenuirostris'') is a species of honeyeater found in south-eastern Australia in forest and woodland areas, as well as gardens in urban areas of Canberra, Sydney, Melbourne and Adelaide. It is around 15 cm long, and has a distinctive black, white and chestnut plumage, a red eye, and a long downcurved bill. Taxonomy Originally described as ''Certhia tenuirostris'' by the English ornithologist John Latham in 1801, it is a member of the small genus '' Acanthorhynchus'' with one other, the western spinebill of Western Australia. The generic name is derived from the Greek translation of spinebill, namely ''acantho-''/ακανθο- 'spine' and ''rhynchos''/ρυνχος 'bill'. Its specific epithet is from Latin ''tenuis'' 'narrow' and ''rostrum'' 'bill'. Other English names include spine-billed honeyeater and awl-bird or cobbler's awl bird. The eastern spinebill is polytypic, consisting of the subspecies ''A. t. cairnsensis'', ''A. t. dub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Lewin
John William Lewin (1770 – 27 August 1819) was an English-born artist active in Australia from 1800. The first professional artist of the colony of New South Wales, he illustrated the earliest volumes of Australian natural history. Many of his illustrations were of native Australian birds on native Australian plants. Early life Lewin was the son of a professional scientific artist, William Lewin, who was the author of an eight-volume work ''The Birds of Great Britain'' (1789–94). William Lewin's two sons, John William and Thomas, worked with him preparing work. William acknowledges their work in the preface to his book. Around 1797, John Lewin was keen to visit New South Wales. To New South Wales John Lewin planned to travel on HMS ''Buffalo'' for New South Wales in 1798 to record ornithological and entomological life for a British patron, Dru Drury. Somehow he missed this voyage but his wife travelled on it and arrived 3 May 1799. Lewin did travel on the ''Minerva'', arriv ...
