Parrot
Parrots, also known as psittacines (), are birds of the roughly 398 species in 92 genera comprising the order Psittaciformes (), found mostly in tropical and subtropical regions. The order is subdivided into three superfamilies: the Psittacoidea ("true" parrots), the Cacatuoidea (cockatoos), and the Strigopoidea (New Zealand parrots). One-third of all parrot species are threatened by extinction, with higher aggregate extinction risk ( IUCN Red List Index) than any other comparable bird group. Parrots have a generally pantropical distribution with several species inhabiting temperate regions in the Southern Hemisphere, as well. The greatest diversity of parrots is in South America and Australasia. Characteristic features of parrots include a strong, curved bill, an upright stance, strong legs, and clawed zygodactyl feet. Many parrots are vividly coloured, and some are multi-coloured. Most parrots exhibit little or no sexual dimorphism in the visual spectrum. They form the most ...

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.

Psittacoidea
The true parrots are about 350 species of hook-billed, mostly herbivorous birds forming the superfamily Psittacoidea, one of the three superfamilies in the biological order Psittaciformes (parrots). True parrots are widespread, with species in Mexico, Central and South America, sub-Saharan Africa, India, Southeast Asia, Australia, and eastwards across the Pacific Ocean as far as Polynesia. The true parrots include many of the familiar parrots including macaws, conures, lorikeets, eclectus, Amazon parrots, grey parrot, and budgerigar. Most true parrots are colourful and flighted, with a few notable exceptions. Overview True parrots have a beak with a characteristic curved shape, the jaw with a mobility slightly higher than where it connects with the skull, and a generally upright position. They also have a large cranial capacity and are one of the most intelligent bird groups. They are good fliers and skillful climbers on branches of trees. Some species can imitat ...

Lesser Vasa Parrot
The lesser vasa parrot or black parrot (''Coracopsis nigra'') is a black coloured parrot endemic to most of Madagascar. It is one of four species of vasa parrots, the others being the greater vasa parrot ''C. vasa'', the Seychelles black parrot (''C. barklyi''), and the Comoros black parrot (''C. sibilans''). The latter two were formerly considered conspecific with the lesser vasa parrot. Lesser vasa parrots inhabit the mangrove swamps and evergreen forests of Madagascar. They eat seeds, blossoms and fruit - especially berries and mangos. They build their nests in tree hollows and go through courtship in February. During this time, the female may shed the feathers on her head giving it a yellowish tone. The male's beak may also turn white during this time. Taxonomy In 1743 the English naturalist George Edwards included a picture and a description of the lesser vasa parrot in his ''A Natural History of Uncommon Birds''. He used the English name "Black Parrot from Madag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Australian Ringneck
The Australian ringneck (''Barnardius zonarius'') is a parrot native to Australia. Except for extreme tropical and highland areas, the species has adapted to all conditions. Treatments of genus ''Barnardius'' have previously recognised two species, the Port Lincoln parrot (''Barnardius zonarius'') and the mallee ringneck (''Barnardius barnardi''), but due to these readily interbreeding at the contact zone they are usually regarded as a single species ''B. zonarius'' with subspecific descriptions. Currently, four subspecies are recognised, each with a distinct range. In Western Australia, the ringneck competes for nesting space with the rainbow lorikeet, an introduced species. To protect the ringneck, culls of the lorikeet are sanctioned by authorities in this region. Overall, though, the ringneck is not a threatened species. Description The subspecies of the Australian ringneck differ considerably in colouration. It is a medium size species around 33 cm (11 in ...

Palm Cockatoo
The palm cockatoo (''Probosciger aterrimus''), also known as the goliath cockatoo or great black cockatoo, is a large smoky-grey or black parrot of the cockatoo family native to New Guinea, Aru Islands, and Cape York Peninsula. It has a very large black beak and prominent red cheek patches. Taxonomy The palm cockatoo was originally described by German naturalist Johann Friedrich Gmelin in 1788 as ''Psittacus aterrimus''. Its specific name, ''Probosciger aterrimus'', is from Latin ''proboscis'', long thin nose + ''-ger'', carry, and Latin superlative adjective for ''ater'', black, hence a "black irdwith a long thin nose (beak)". The only member of the monotypic genus, ''Probosciger'', the palm cockatoo is a member of the white cockatoo subfamily Cacatuinae. Earlier limited genetic studies found it to be the earliest offshoot from the ancestors of what have become the cockatoo family. Four subspecies are recognized, three poorly differentiated and one distinctive. The Cape ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blue-and-yellow Macaw
The blue-and-yellow macaw (''Ara ararauna''), also known as the blue-and-gold macaw, is a large South American parrot with mostly blue top parts and light orange underparts, with gradient hues of green on top of its head. It is a member of the large group of neotropical parrots known as macaws. It inhabits forest (especially varzea, but also in open sections of ''terra firme'' or unflooded forest), woodland and savannah of tropical South America. They are popular in aviculture because of their striking color, ability to talk, ready availability in the marketplace, and close bonding to humans. They can also live for 65–70 years. Taxonomy The blue-and-yellow macaw was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his '' Systema Naturae''. He placed it with all the other parrots in the genus ''Psittacus'' and coined the binomial name ''Psittacus ararauna''. This macaw is now one of the eight extant species placed in the genus '' A ...

Bird
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 swim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beak
The beak, bill, or rostrum is an external anatomical structure found mostly in birds, but also in turtles, non-avian dinosaurs and a few mammals. A beak is used for eating, preening, manipulating objects, killing prey, fighting, probing for food, courtship, and feeding young. The terms ''beak'' and ''rostrum'' are also used to refer to a similar mouth part in some ornithischians, pterosaurs, cetaceans, dicynodonts, anuran tadpoles, monotremes (i.e. echidnas and platypuses, which have a beak-like structure), sirens, pufferfish, billfishes and cephalopods. Although beaks vary significantly in size, shape, color and texture, they share a similar underlying structure. Two bony projections – the upper and lower mandibles – are covered with a thin keratinized layer of epidermis known as the rhamphotheca. In most species, two holes called ''nares'' lead to the respiratory system. Etymology Although the word "beak" was, in the past, generally restricted to the sharpened b ...
