Pale-headed Rosella
The pale-headed rosella (''Platycercus adscitus''), is a broad-tailed parrot of the genus ''Platycercus'' native to northeastern Australia. It is a moderate-size parrot with a pale yellow head, predominantly white cheeks, scalloped black and gold back and pale blue underparts. Two subspecies are recognised, although some authorities consider it to be conspecific with the eastern rosella of southeastern Australia. Found in open woodland, it feeds on seeds and fruit. As with other rosellas, the pale-headed rosella nests in hollows of large trees. Even found to have a nest in a tree hollow 50 cm under ground rather than above ground. It readily adapts to aviculture and is sold as a cagebird. Taxonomy The pale-headed rosella was formally described in 1790 by the English ornithologist John Latham and given the binomial name ''Psittacus adscitus''. The specific epithet is from Latin ''asciscere'' meaning "to approve". Latham did not specify a locality but in 1912 Gregory Mathe ...

John Latham (ornithologist)
John Latham (27 June 1740 – 4 February 1837) was an English physician, natural history, naturalist and author. His main works were ''A General Synopsis of Birds'' (1781–1801) and ''A General History of Birds'' (1821–1828). He was able to examine specimens of Australian birds that reached England in the final twenty years of the 18th century, and was responsible for providing English names for many of them. He named some of Australia's most famous birds, including the emu, sulphur-crested cockatoo, wedge-tailed eagle, superb lyrebird, Australian magpie, magpie-lark, white-throated needletail and pheasant coucal. Latham has been called the "grandfather" of Australian ornithology. He was also the first to describe the hyacinth macaw from South America. Biography John Latham was born on 27 June 1740 at Eltham in northwest Kent. He was the eldest son of John Latham (died 1788), a surgeon, and his mother, who was a descendant of the Sothebys, in Yorkshire. He was educated at Merc ...

Cape York Peninsula
The Cape York Peninsula is a peninsula located in Far North Queensland, Australia. It is the largest wilderness in northern Australia.Mittermeier, R.E. et al. (2002). Wilderness: Earth's last wild places. Mexico City: Agrupación Sierra Madre, S.C. The land is mostly flat and about half of the area is used for grazing cattle. The relatively undisturbed eucalyptus-wooded savannahs, tropical rainforests and other types of habitat are now recognised and preserved for their global environmental significance. Although much of the peninsula remains pristine, with a diverse repertoire of endemic flora and fauna, some of its wildlife may be threatened by industry and overgrazing as well as introduced species and weeds.Mackey, B. G., Nix, H., & Hitchcock, P. (2001). The natural heritage significance of Cape York Peninsula. Retrieved 15 January 2008, froepa.qld.gov.au. The northernmost point of the peninsula is Cape York (Queensland), Cape York. The land has been occupied by a number of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Of Queensland
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 common ostrich. There are over 11,000 living species and they are split into 44 orders. More than half are passerine or "perching" birds. Birds have 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 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 furth ...

Xanthium Strumarium
''Xanthium strumarium'' (rough cocklebur, Noogoora burr, clotbur, common cocklebur, large cocklebur, woolgarie bur) is a species of annual plants of the family Asteraceae. Some sources claim it originates in southern Europe and Asia, but has been extensively naturalized elsewhere. Others, such as the Flora of China and Flora of North America, state it originates in the Americas but was an early introduction to Eurasia. Reproductive biology The species is monoecious, with the flowers borne in separate unisexual heads: staminate (male) heads situated above the pistillate (female) heads in the inflorescence. The pistillate heads consist of two pistillate flowers surrounded by a spiny involucre. Upon fruiting, these two flowers ripen into two brown to black achenes and they are completely enveloped by the involucre, which becomes a bur. The bur, being buoyant, easily disperses in the water for plants growing along waterways. However, the bur, with its hooked projections, is obviously ...

Melaleuca
''Melaleuca'' () is a genus of nearly 300 species of plants in the myrtle family, Myrtaceae, commonly known as paperbarks, honey-myrtles, bottlebrushes or tea-trees (although the last name is also applied to species of '' Leptospermum''). They range in size from small shrubs that rarely grow to more than high, to trees up to . Their flowers generally occur in groups, forming a "head" or "spike" resembling a brush used for cleaning bottles, containing up to 80 individual flowers. Melaleucas are an important food source for nectarivorous insects, birds, and mammals. Many are popular garden plants, either for their attractive flowers or as dense screens and a few have economic value for producing fencing and oils such as "tea tree" oil. Most melaleucas are endemic to Australia, with a few also occurring in Malesia. Seven are endemic to New Caledonia, and one is found only on Australia's Lord Howe Island. Melaleucas are found in a wide variety of habitats. Many are adapted ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Melaleuca Linariifolia
''Melaleuca linariifolia'' is a plant in the myrtle Family (biology), family Myrtaceae, and is endemic to eastern Australia.
