Sulfur-crested Cockatoo
The sulphur-crested cockatoo (''Cacatua galerita'') is a relatively large white cockatoo found in wooded habitats in Australia, New Guinea, and some of the islands of Indonesia. They can be locally very numerous, leading to them sometimes being considered pests. A highly intelligent bird, they are well known in aviculture, although they can be demanding pets. Subspecies There are four recognised subspecies: A 2024 genetic study found that the Triton cockatoo is genetically distinct from the two Australian forms of sulphur-crested cockatoo and should therefore be considered a separate species, ''Cacatua triton''. Description Sulphur-crested cockatoos are long, with the Australian subspecies larger than subspecies from New Guinea and nearby islands. The plumage is overall white, while the underwing and -tail are tinged yellow. The expressive crest is yellow. The bill is black, the legs are grey, and the eye-ring is whitish. Males typically have almost black eyes, whereas the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pleistocene
The Pleistocene ( ; referred to colloquially as the ''ice age, Ice Age'') is the geological epoch (geology), epoch that lasted from to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek () 'most' and (; Latinized as ) 'new'. The aridification and cooling trends of the preceding Neogene were continued in the Pleistocene. The climate was strongly variable depending on the glacial cycle, oscillating between cold Glacial period, glacial periods and warmer Interglacial, int ...

Cacatua Galerita Fitzroyi 1
''Cacatua'' is a genus of cockatoos found from the Philippines, Indonesia, Papua New Guinea, and Solomon Islands 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 and capture for the wild-bird trade, with the blue-eyed cockatoo considered vulnerable, Moluccan cockatoo, and umbrella cockatoo considered endangered, and the red-vented cockatoo and yellow-crested cockatoo considered critically endangered. Taxonomy Although the name ''Cacatua'' was used in 1760 by French zoologist Mathurin Jacques Brisson, he did not include it in his table of genera and Brisson is not recognised as the authority by the International Commission on Zoological Nomenclature (ICZN). The genus ''Kakatoe'' was introduced by Georges Cuvier in 1801 but this name has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yellow-crested Cockatoo
The yellow-crested cockatoo (''Cacatua sulphurea'') also known as the lesser sulphur-crested cockatoo, is a medium-sized (about 34-cm-long) cockatoo with white plumage, bluish-white bare orbital skin, grey feet, a black bill, and a retractile yellow or orange crest. The sexes are similar. The yellow-crested cockatoo is found in wooded and cultivated areas of East Timor and Indonesia's islands of Sulawesi and the Lesser Sundas. It is easily confused with the largerBirdLife Species Factsheet retrieved 10 February 2010 and more common , which has a more easterly distribution and can be distinguished b ...

Corella (bird)
''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 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 t ...s 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.

Crest (feathers)
The crest is a prominent feature exhibited by several bird species on their heads. It is distinct from features such as casques and cockscombs - sometimes erroneously referred to as "crests", which are bony and fleshy structures respectively. The crest is made up of semiplume feathers: a long rachis with barbs on either side. These are plumulaceous feathers, meaning that they are soft and bendable. In birds, these semiplumes are common along the head, neck, and upper back, and may be used for buoyancy and sensing vibrations. Crests on birds are generally used for display purposes. Cockatoos (a family that also includes corellas and the cockatiel) are part of the parrot family Cacatuidae found in Australia, the Bismarck Archipelago and the Philippines, and are probably the most recognizable birds to feature crests. Cockatoos and cockatiels possess crests which may be raised or lowered at will. Their crests are used to communicate with fellow members of their species, or as a ...

Plumage
Plumage () is a layer of feathers that covers a bird and the pattern, colour, and arrangement of those feathers. The pattern and colours of plumage differ between species and subspecies and may vary with age classes. Within species, there can be different colour morph (zoology), morphs. The placement of feathers on a bird is not haphazard but rather emerges in organized, overlapping rows and groups, and these are known by standardized names. Most birds moult twice a year, resulting in a breeding or ''nuptial plumage'' and a ''basic plumage''. Many ducks and some other species such as the red junglefowl have males wearing a bright nuptial plumage while breeding and a drab ''eclipse plumage'' for some months afterward. The painted bunting's juveniles have two inserted moults in their first autumn, each yielding plumage like an adult female. The first starts a few days after fledging replacing the ''juvenile plumage'' with an ''auxiliary formative plumage''; the second a month o ...

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] |
Greater Sulphur-crested Cockatoo
The greater sulphur-crested cockatoo (''Cacatua galerita galerita'') is the nominate subspecies of the sulphur-crested cockatoo. Its length is up to 50 cm (20 in) and weighs 0.91 kg (2 lb), making it one of the largest cockatoo species. Description The greater sulphur-crested cockatoo is the largest of four sulphur-crested cockatoo subspecies, being significantly heavier than the closely related Eleonora and Triton cockatoos. Its head is white, with a long yellow crest on top of its head. Its body is almost entirely white as well, with a yellow tint on the terminal ends of their head and neck feathers, and on the underside of their wing and tail feathers. They have a downward-curved black beak, which often appears grey from the white powder they produce for grooming. The sexes are nearly identical, with the only difference being the irises of their eyes, which are red in females and very dark brown in males. Taxonomy The greater sulphur-crested cockatoo is also known b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
