Gang-gang Cockatoo
The gang-gang cockatoo (''Callocephalon fimbriatum'') is a parrot found in the cooler and wetter forests and woodlands of Australia, particularly alpine bushland. It is the only species placed in the genus ''Callocephalon''. Mostly mild grey in colour with some lighter scalloping (more pronounced and buffy in females), the male has a red head and crest, while the female has a small fluffy grey crest. It ranges throughout south-eastern Australia. The gang-gang cockatoo is the faunal emblem of the Australian Capital Territory. It is easily identified by its distinctive call, which is described as resembling a creaky gate, or the sound of a cork being pulled from a wine bottle. The name ''gang-gang'' comes from a New South Wales Aboriginal language, probably from one of the coastal languages, although possibly from Wiradjuri. It is probably an onomatopoeic name. Taxonomy In 1803 the British Royal Navy officer James Grant included an illustration of the gang-gang cockatoo in hi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
René Primevère Lesson
René (''Born again (Christianity), born again'' or ''reborn'' in French language, French) is a common given name, first name in French-speaking, Spanish-speaking, and German-speaking countries. It derives from the Latin name Renatus. René is the masculine form of the name (Renée being the feminine form). In some non-Francophone countries, however, there exists the habit of giving the name René (sometimes spelled without an accent) to girls as well as boys. In addition, both forms are used as surnames (family names). René as a first name given to boys in the United States reached its peaks in popularity in 1969 and 1983 when it ranked 256th. Since 1983 its popularity has steadily declined and it ranked 881st in 2016. René as a first name given to girls in the United States reached its peak in popularity in 1962 when it ranked 306th. The last year for which René was ranked in the top 1000 names given to girls in the United States was 1988. Persons with the given name * Ren ...

Bass River (Victoria)
The Bass River, a perennial stream, perennial river of the Western Port catchment, is located in the West Gippsland region of the Australian state of Victoria (Australia), Victoria. Location and features The Bass River rises below the locale of Woodleigh, west of the South Gippsland Highway, with its headwaters drawn from the Strzelecki Ranges, north of the town of .

Tree
In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, e.g., including only woody plants with secondary growth, only plants that are usable as lumber, or only plants above a specified height. But wider definitions include taller palms, tree ferns, bananas, and bamboos. Trees are not a monophyletic taxonomic group but consist of a wide variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some trees reaching several thousand years old. Trees evolved around 400 million years ago, and it is estimated that there are around three trillion mature trees in the world currently. A tree typically has many secondary branches supported cle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cockatoo
A cockatoo is any of the 21 species of parrots belonging to the family Cacatuidae, the only family in the superfamily Cacatuoidea. Along with the Psittacoidea ( true parrots) and the Strigopoidea (large New Zealand parrots), they make up the order Psittaciformes. The family has a mainly Australasian distribution, ranging from the Philippines and the eastern Indonesian islands of Wallacea to New Guinea, the Solomon Islands and Australia. Cockatoos are recognisable by their prominent crests and curved bills. Their plumage is generally less colourful than that of other parrots, being mainly white, grey, or black and often with coloured features in the crest, cheeks, or tail. On average, they are larger than other parrots; however, the cockatiel, the smallest cockatoo species, is medium-sized. The phylogenetic position of the cockatiel remains unresolved, except that it is one of the earliest offshoots of the cockatoo lineage. The remaining species are in two main clades. ...

Kangaroo Island
Kangaroo Island (, ) is Australia's third-largest island, after Tasmania and Melville Island, Northern Territory, Melville Island. It lies in the state of South Australia, southwest of Adelaide. Its closest point to the mainland is Snapper Point in Backstairs Passage, which is from the Fleurieu Peninsula. The native population of Aboriginal Australians that once occupied the island (sometimes referred to as the Kartan people) disappeared from the archaeological record sometime after the land became an island following the sea level rise, rising sea levels associated with the Last Glacial Period around 10,000 years ago. It was subsequently settled intermittently by sealers and whalers in the early 19th century, and from 1836 on a permanent basis during the British colonisation of South Australia. Since then the island's economy has been principally agricultural, with a Jasus edwardsii, southern rock lobster fishery and with tourism growing in importance. The largest town, and ...

Galah
The galah (; ''Eolophus roseicapilla''), less commonly known as the pink and grey cockatoo or rose-breasted cockatoo, is an Australian species of cockatoo and the only member of the genus ''Eolophus''. The galah is adapted to a wide variety of modified and unmodified habitats and is one of Australia's most abundant and widespread bird species. The species is endemic to mainland Australia. It was introduced species, introduced to Tasmania, where it is now widespread, in the mid-19th century and much more recently to New Zealand. Etymology The term galah is derived from ''gilaa'', a word from the Yuwaalaraay and neighbouring Australian Aboriginal languages, Aboriginal languages spoken in north-western New South Wales.

Palm Cockatoo
The palm cockatoo (''Probosciger aterrimus''), also known as the goliath cockatoo or great black cockatoo, is a large, smoky-grey/black Psittaciformes, parrot of the cockatoo family native to New Guinea, the Aru Islands Regency, Aru Islands and the Cape York Peninsula in Queensland, Australia. It has a crest of long feathers atop its head, with a very large and strong, sharply-hooked black beak (with which it can easily open nuts and seeds), and prominent bright-red cheek patches. Taxonomy The palm cockatoo was Species description, formally described in 1788 by naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's ''Systema Naturae'', in which he classified the bird with other parrots in the genus ''Psittacus'' and coined the binomial nomenclature, binomial name ''Psittacus aterrimus''. Gmelin based his description on the "black cockatoo" that had been described and illustrated in 1764 by English naturalist George Edwards (naturalist), George ...

Sexual Dichromatism
Sexual dimorphism is the condition where sexes of the same species exhibit different morphological characteristics, including characteristics not directly involved in reproduction. The condition occurs in most dioecious species, which consist of most animals and some plants. Differences may include secondary sex characteristics, size, weight, color, markings, or behavioral or cognitive traits. Male-male reproductive competition has evolved a diverse array of sexually dimorphic traits. Aggressive utility traits such as "battle" teeth and blunt heads reinforced as battering rams are used as weapons in aggressive interactions between rivals. Passive displays such as ornamental feathering or song-calling have also evolved mainly through sexual selection. These differences may be subtle or exaggerated and may be subjected to sexual selection and natural selection. The opposite of dimorphism is ''monomorphism'', when both biological sexes are phenotypically indistinguishable from e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subspecies
In Taxonomy (biology), biological classification, subspecies (: subspecies) is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (Morphology (biology), morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated as subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific name, infraspecific ranks, such as variety (botany), variety, may be named. In bacteriology and virology, under standard International Code of Nomenclature of Prokaryotes, bacterial nomenclature and virus clas ...

Monotypic
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. Theoretical implications Monotypic taxa present several important theoretical challenges in biological classification. One key issue is known as "Gregg's Paradox": if a single species is the only member of multiple hierarchical levels (for example, being the only species in its genus, which is the only genus in its family), then each level needs a distinct definition to maintain logical structure. Otherwise, the different taxonomic ranks become effectively identical, which creates problems for organizing biological diversity in a hierarchical syste ...
