Budgerigar Colour Mutations
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 ... [...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 bills o ...

Liverpool Plains
The Liverpool Plains are an extensive agricultural area covering about of the north-western slopes of New South Wales in Australia. These plains are a region of prime agricultural land bounded to the east by the Great Dividing Range, to the south by the Liverpool Range and on the west by the Warrumbungle Range. The area is drained by the Namoi River and its tributaries, the Mooki River and the Peel River. There are many depressions, across the plains, which remain as lakes for long periods after heavy rain. These plains are unusual in that many steep hills arise suddenly from the plains. Towns in the Liverpool Plains include Gunnedah, Narrabri, Quirindi, Werris Creek and Tamworth. Smaller villages include Breeza, Carroll, Mullaley and Willow Tree. Most of the region nowadays comes under the jurisdiction of Liverpool Plains Shire Council. However substantial parts of the region also form part of the Gunnedah and Tamworth local government areas. History The Liverpool Pla ...

Phylogenetic
In biology, phylogenetics (; from Greek φυλή/ φῦλον [] "tribe, clan, race", and wikt:γενετικός, γενετικός [] "origin, source, birth") is the study of the evolutionary history and relationships among or within groups of organisms. These relationships are determined by Computational phylogenetics, phylogenetic inference methods that focus on observed heritable traits, such as DNA sequences, protein amino acid sequences, or morphology. The result of such an analysis is a phylogenetic tree—a diagram containing a hypothesis of relationships that reflects the evolutionary history of a group of organisms. The tips of a phylogenetic tree can be living taxa or fossils, and represent the "end" or the present time in an evolutionary lineage. A phylogenetic diagram can be rooted or unrooted. A rooted tree diagram indicates the hypothetical common ancestor of the tree. An unrooted tree diagram (a network) makes no assumption about the ancestral line, and does ...

Pezoporus
The genus ''Pezoporus'' contains three Australian species: the night parrot (''Pezoporus occidentalis'') and the cryptic ground parrots, the eastern ground parrot (''Pezoporus wallicus'') and the western ground parrot (''Pezoporus flaviventris''). The night parrot was previously separated in a distinct genus, ''Geopsittacus''. The genus is part of the tribe The term tribe is used in many different contexts to refer to a category of human social group. The predominant worldwide usage of the term in English is in the discipline of anthropology. This definition is contested, in part due to confli ... Pezoporini.

Neophema
The genus ''Neophema'' is an Australian genus with six or seven species. They are small, basically dull green parrots differentiated by patches of other colours, and are commonly known as grass parrots. The genus has some sexual dichromatism, with males having brighter hues. Taxonomy Sometimes the broad-tailed parrots are considered a subfamily. In this case, ''Neophema'' and Bourke's parrot are united in the tribe Neophemini. mtDNA sequence data (Miyaki ''et al.'' 1998) suggests that the former may be correct, but the latter almost certainly is not. Rather, it appears, the group would need to include more closely related forms, such as the budgerigar and the ''Pezoporus'' ground-parrots. However, while Joseph ''et al.'' (2011) also found ''Neophema'' to be related both Bourke's parrot and ground-parrots and form part of the tribe Pezoporini, they are not related to the budgerigar. Analysis of mitochondrial DNA published in 2021 indicated the ancestors of Bourke's parrot and the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Latin Language
Latin (, or , ) is a classical language belonging to the Italic languages, Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italy (geographical region), Italian region and subsequently throughout the Roman Empire. Even after the Fall of the Western Roman Empire, fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a fusional language, highly inflected language, with three distinct grammatical gender, genders (masculine, feminine, and neuter), six or seven ...

Ancient Greek Language
Ancient Greek includes the forms of the Greek language used in ancient Greece and the classical antiquity, ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Greek Dark Ages, Dark Ages (), the Archaic Greece, Archaic period (), and the Classical Greece, Classical period (). Ancient Greek was the language of Homer and of fifth-century Athens, fifth-century Athenian historians, playwrights, and Ancient Greek philosophy, philosophers.

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 namesak ...

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 describing hi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
