Cockatoo Docks
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. Th ...

Sulphur-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 Pest (organism), 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 (feathers), crest is yellow. The bill is black, the legs are grey, and the eye-ring is whitish. Males typically h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
True Parrot
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 imitate the hum ...

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 ...

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 pecking, grasping, and holding (in probing for food, eating, manipulating and carrying objects, killing prey, or fighting), preening, 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, rhynchosaurs, anuran tadpoles, monotremes (i.e. echidnas and platypuses, which have a bill-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 wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Kaka (bird)
The genus ''Nestor'' is one of the two extant genera of the parrot family Strigopidae. Together with the kākāpō, and the extinct parrots in the genus '' Nelepsittacus'', they form the parrot superfamily Strigopoidea. The ''Nestor's'' genus contains two extant parrot species from New Zealand and two extinct species from Norfolk Island, Australia and Chatham Island, New Zealand, respectively. All species are large stocky birds with short squarish tails. A defining characteristic of the genus is the tongue, which is tipped with a hair-like fringe. The superficial resemblance of this tongue to that of lorikeets has led some taxonomists to consider the two groups closely related, but DNA evidence shows they are not. Classification All four species in the genus ''Nestor'' are thought to stem from a 'proto-kaka', dwelling in the forests of New Zealand 5 million years ago. The closest living relative of the genus is the kākāpō (''Strigops habroptilus'').de Kloet, R.S.; de Kloet, S. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Numerous smaller islands are located to the west and east.

The eastern half of the island is the major land mass of the nation of Papua New Guinea.
