Budgerigar
The budgerigar ( ; ''Melopsittacus undulatus''), also known as the common parakeet or shell parakeet, is a small, long-tailed, seed-eating parrot usually nicknamed the budgie ( ), or in American English, the parakeet. Budgies are the only species in the genus ''Melopsittacus''. Naturally, the species is green and yellow with black, scalloped markings on the nape, back, and wings. Budgies are bred in captivity with colouring of blues, whites, yellows, greys, and even with small crests. Juveniles and chicks are monomorphic, while adults are told apart by their cere colouring, and their behaviour. The species is the only member of the genus ''Melopsittacus'', which is the only genus in the Melopsittacini tribe. The origin of the budgerigar's name is unclear. First recorded in 1805, budgerigars are popular pets around the world due to their small size, low cost, and ability to mimic human speech. They are likely the third most popular pet in the world, after the domesticated ...

Parakeet
A parakeet is any one of many small to medium-sized species of parrot, in multiple genera, that generally has long tail feathers. Etymology and naming The name ''parakeet'' is derived from the French wor''perroquet'' which is reflected in some older spellings that are still sometimes encountered, including paroquet or paraquet. However, in modern French''perruche''is used to refer to parakeets and similar-sized parrots. In American English, the word ''parakeet'' usually refers to the budgerigar, which is one species of parakeet. Summary Parakeets comprise about 115 species of birds that are seed-eating parrots of small size, slender build, and long, tapering tails. The Australian budgerigar, also known as "budgie", ''Melopsittacus undulatus'', is probably the most common parakeet. It was first described by zoologists in 1891. It is the most popular species of parakeet kept as a pet in North America and Europe. The term "grass parakeet" (or ''grasskeet'') refers to ma ...

Parrots
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 ...

Opportunistic Breeders
Flexible or opportunistic breeders mate whenever the conditions of their environment become favorable. Their ability and motivation to mate are primarily independent of day-length (photoperiod) and instead rely on cues from short-term changes in local conditions like rainfall, food abundance and temperature. Another factor is the presence of suitable breeding sites, which may only form with heavy rain or other environmental changes.WE Duellman, L Trueb. ''Biology of amphibians.'' The Johns Hopkins University Press, 1994, p. 20 Thus, they are distinct from seasonal breeders that rely on changes in day length to induce entry into estrus and to cue mating, and continuous breeders like humans that can mate year-round. Other categories of breeders that perhaps can be subdivided under the heading "opportunistic" have been used to describe many species, such as many that are anurans like frogs. These include sporadic wet and sporadic dry, describing animals that breed sporadically not a ...

Ancient Greek Language
Ancient Greek includes the forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Dark Ages (), the Archaic period (), and the Classical period (). Ancient Greek was the language of Homer and of fifth-century Athenian historians, playwrights, and philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Epic and Classical periods of the language. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regarded as a separate historical stage, although its earliest form closely resembles Attic Greek and its latest form approaches Medieval Greek. There were several regional dialects of Ancient Greek, of which Attic Greek developed into Koine ...

Lories And Lorikeets
Loriini is a tribe of small to medium-sized arboreal parrots characterized by their specialized brush-tipped tongues for feeding on nectar of various blossoms and soft fruits, preferably berries. The species form a monophyletic group within the parrot family Psittaculidae. The group consists of the lories and lorikeets. Traditionally, they were considered a separate subfamily (Loriinae) from the other subfamily ( Psittacinae) based on the specialized characteristics, but recent molecular and morphological studies show that the group is positioned in the middle of various other groups. They are widely distributed throughout the Australasian region, including south-eastern Asia, Polynesia, Papua New Guinea, Timor Leste and Australia, and the majority have very brightly coloured plumage. Etymology The word "lory" comes from the Malay ''lūri'', a name used for a number of species of colourful parrots. The name was used by the Dutch writer Johan Nieuhof in 1682 in a book describin ...

Fig Parrot
Fig parrots (Cyclopsittini) are a small tribe of Australasian parrots in the family Psittaculidae, made up of five species in two genera (''Cyclopsitta'' and ''Psittaculirostris''). Fig parrots are found on and around the island of New Guinea, within the territories of Indonesia, Papua New Guinea, and tropical Australia. Description Fig parrots are small, stocky, arboreal parrots with short, wedge-shaped tails. They possess proportionately large, broad bills and smooth tongues. Sexual dimorphism is typically pronounced, with the exception of Coxen's fig parrot (''Cyclopsitta diopthalma coxeni''). Those in the genus ''Cyclopsitta'' are generally smaller than those in ''Psittaculirostris''. Their preferred habitats are the tropical and subtropical rainforests, though they can also be found foraging in the surrounding biomes. They can usually be seen flying swiftly in straight lines, well above the tree canopy. Their diets consist mainly of fruit, particularly their namesake ...

Cyclopsitta
''Cyclopsitta'' is a genus of parrot in the family Psittaculidae. It contains two species: The genus name ''Cyclopsitta'' is a combination of the Greek name of the mythical Cyclops (a race of one-eyed Sicilian giants, whose name is a combination of the Greek word ''kuklos'', meaning "circle" and ''ōps'', meaning "eye"), and the modern Latin Latin (, or , ) is a classical language belonging to the Italic languages, Italic branch of the Indo-European languages.

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 ...

Oxford University Press
Oxford University Press (OUP) is the university press of the University of Oxford. It is the largest university press in the world, and its printing history dates back to the 1480s. Having been officially granted the legal right to print books by decree in 1586, it is the second oldest university press after Cambridge University Press. It is a department of the University of Oxford and is governed by a group of 15 academics known as the Delegates of the Press, who are appointed by the vice-chancellor of the University of Oxford. The Delegates of the Press are led by the Secretary to the Delegates, who serves as OUP's chief executive and as its major representative on other university bodies. Oxford University Press has had a similar governance structure since the 17th century. The press is located on Walton Street, Oxford, opposite Somerville College, in the inner suburb of Jericho. For the last 500 years, OUP has primarily focused on the publication of pedagogical texts ...
