Licmetis
''Licmetis'' is a subgenus of the white cockatoos (genus ''Cacatua''). They are collectively known as corellas in Australia. Three of the six species are primarily – or only – found in Australia, while the Philippines, Indonesia, and the Solomons each have an endemic species. They are relatively small cockatoos and – unlike the members of the subgenus ''Cacatua'' – all have pale bills. While most show yellow-tinged underwings and some red to the face, none has conspicuously coloured crests.

Cacatua
''Cacatua'' is a genus of cockatoos found from the Philippines and Wallacea east to the Solomon Islands and south to Australia. They have a primarily white plumage (in some species tinged pinkish or yellow), an expressive crest, and a black (subgenus '' Cacatua'') or pale (subgenus '' Licmetis'') bill. Today, several species from this genus are considered threatened due to a combination of habitat loss Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby ... and capture for the wild bird trade, with the blue-eyed cockatoo, Moluccan cockatoo, and umbrella cockatoo considered vulnerable, and the red-vented cockatoo and yellow-crested cockatoo considered critically endangered. The genus was first described by Brisson in 1790, with the white cockatoo (''C. alba'') subsequently designa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Western Corella
The western corella (''Cacatua pastinator'') also known as the western long-billed corella, is a species of white cockatoo endemic to south-western Australia. Taxonomy Cacatuidae is one of three families of the large and diverse avian order Psittaciformes which consists of 370 species. Cockatoos are distinguished from other parrots by five main morphological features – a crest, lack of "green" dyck-texture in the plumage, yellow natal down, a gall bladder, and bridge temporal fossa The western corella (also known as the western long-billed corella) ''Cacatua pastinator'' consists of two geographically isolated sub-species, Butler's corella (''Cacatua pastinator butleri'') and Muir's corella (''Cacatua pastinator pastinator'')Chapman, T., Cale, B. (2008). Muir’s Corella (''Cacatua pastinator pastinator'') Recovery Plan. Department of Environment and Conservation, Western Australia.

Cockatoo
A cockatoo is any of the 21 parrot species 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 the 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 a small bird. The phylogenetic position of the cockatiel remains unresolved, other than that it is one of the earliest offshoots of the cockatoo lineage. The remaining species are in two main clades.

Long-billed Corella
The long-billed corella or slender-billed corella (''Cacatua tenuirostris'') is a cockatoo native to Australia, which is similar in appearance to the little corella. This species is mostly white, with a reddish-pink face and forehead, and has a long, pale beak, which is used to dig for roots and seeds. It has reddish-pink feathers on the breast and belly. Taxonomy The long-billed corella does not have any recognized subspecies. The first formal written description was by German naturalist Heinrich Kuhl in 1820. It is one of several related species of cockatoos called corellas and classified in the subgenus ''Licmetis'' within the genus ''Cacatua'', members of which are known as "white cockatoos". Description The adult long-billed corella measures from 38 to 41 cm in length, has a wingspan around 80–90 cm, and averages 567 g in weight. It has a long, bone-coloured beak, and a rim of featherless, bluish skin around the eyes. The plumage is predominantly white ...

Solomons Cockatoo
The Solomons cockatoo (''Cacatua ducorpsii''), also known as the Ducorps's cockatoo, Solomons corella or broad-crested corella, is a species of cockatoo endemic to the Solomon Islands archipelago. This small white cockatoo is larger than the Tanimbar corella yet smaller than the umbrella cockatoo. The species is common across most of the Solomons, absent only from Makira in the south. It inhabits lowland rainforests, secondary forests, cleared areas and gardens. Description The Solomons cockatoo is about long. They are predominantly white. They have a blue eye ring and a recumbent crest which resembles a sail in its raised state. As other members of the subgenus ''Licmetis'', it has a pale bill. Distribution & population The Solomons cockatoo is abundant on all islands in the archipelago except Makira and surrounding islands. Ornithologists estimate that the bird has a population of around 100,000 individual birds. It has been listed as Least Concern by the International ...

Tanimbar Corella
The Tanimbar corella (''Cacatua goffiniana''), also known as Goffin's cockatoo, is a species of cockatoo endemic to forests of Yamdena, Larat and Selaru, all islands in the Tanimbar Islands archipelago in Indonesia. It has been introduced to the Kai Islands, Indonesia, Puerto Rico and Singapore. This species was only formally described in 2004, after it was discovered that the previous formal descriptions pertained to individuals of a different cockatoo species, the Ducorps' or Solomons cockatoo (''Cacatua ducorpsii''). Tanimbar corellas are the smallest of the white cockatoos. It is classified as Near Threatened due to deforestation and bird trade. It breeds well in captivity and there is a large avicultural population. Description Tanimbar corellas weigh, on average, about for females and for males. They are about from head to tail. Like all members of the family Cacatuidae, the Tanimbar corella is crested, meaning it has a collection of feathers on its head that it can ...

Red-vented Cockatoo
The red-vented cockatoo (''Cacatua haematuropygia''), also known as the Philippine cockatoo and locally katala, abukay, agay or kalangay, is a species of cockatoo. It is endemic to the Philippines though pressured by various environmental degradation and illegal pet trades, the population of the Philippine cockatoo is somehow growing owing to Katala Organization.It is roughly the size and shape of the Tanimbar corella, but is easily distinguished by the red feathers around the vent. It is threatened by habitat loss and the cage-bird trade. Description The plumage is all white with red undertail coverts tipped white, yellowish undertail and pale yellow underwings. It is long and has an wingspan. Ebird describes it is "A rare large parrot of forest on Palawan and several other scattered islands. Heavily persecuted. Can roost on small islets or in mangroves and forage in more open areas, including agricultural fields. Mostly white with a pale yellowish cheek, undertail, and u ...

Little Corella
The little corella (''Cacatua sanguinea''), also known as the short-billed corella, bare-eyed cockatoo, blood-stained cockatoo, and little cockatoo is a white cockatoo native to Australia and southern New Guinea. It was known as ''Birdirra'' among the Yindjibarndi people of the central and western Pilbara. They would keep them as pets, or traditionally cook and eat them. The downy feathers are used in traditional ceremonies and dances where they adorn head and armbands. Taxonomy The first recorded description of the species was by English ornithologist John Gould in 1843. There are four subspecies as follows: * ''C. s. sanguinea'' * ''C. s. normantoni'' * ''C. s. transfreta'' * ''C. s. gymnopis'' * ''C. s. westralensis'' (Mathews 1917) Description The little corella is a small white cockatoo growing to in length and weighs , with a mean weight of . It is similar in appearance to both the long-billed corella and the western corella, but the little corella is smaller, and unl ...

Cacatua (subgenus)
''Cacatua'' is a subgenus of the white cockatoos (genus ''Cacatua''). They are found in wooded habitats from Wallacea east to the Bismarck Archipelago and south to Australia. With the exception of the yellow-crested cockatoo, all are relatively large cockatoos with a total length of 45–55 cm (18–22 in). Their plumage is mainly white (tinged pinkish in the salmon-crested cockatoo), and the underwing and -tail have a yellowish tinge. Their crest is expressive and brightly coloured in most species. Unlike the members of the subgenus ''Licmetis'', the members of the subgenus ''Cacatua'' have a black bill. The sulphur-crested cockatoo is relatively widespread and can even be seen in suburban habitats in some parts of its range, but the remaining members of this subgenus all have relatively small distributions and are considered threatened by the IUCN due to a combination of habitat loss and capture for the wild bird trade.

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
