Parakeet Outside Its Nest (Hampstead Heath)
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 ...

Male And Female Parakeet 1
Male (symbol: ♂) is the sex of an organism that produces the gamete (sex cell) known as sperm, which fuses with the larger female gamete, or ovum, in the process of fertilization. A male organism cannot reproduce sexually without access to at least one ovum from a female, but some organisms can reproduce both sexually and asexually. Most male mammals, including male humans, have a Y chromosome, which codes for the production of larger amounts of testosterone to develop male reproductive organs. Not all species share a common sex-determination system. In most animals, including humans, sex is determined genetically; however, species such as ''Cymothoa exigua'' change sex depending on the number of females present in the vicinity. In humans, the word ''male'' can also be used to refer to gender in the social sense of gender role or gender identity. Overview The existence of separate sexes has evolved independently at different times and in different lineages, an example of ...

Psittacula
Members of the parrot genus ''Psittacula'' or Afro-Asian ring-necked parrots they are commonly known in aviculture originate from Africa to South-East Asia. It is a widespread group with a clear concentration of species in south Asia, but also with representatives in Africa and the islands of the Indian Ocean. This is the only genus of Parrot which has the majority of its species in continental Asia. Of all the extant species only '' Psittacula calthropae'', ''Psittacula caniceps'' and ''Psittacula echo'' do not have a representative subspecies in any part of mainland continental Asia. The rose-ringed parakeet, ''Psittacula krameri'', is one of the most widely distributed of all parrots. The other two Asian genera, '' Loriculus'' and ''Psittinus'' are represented by only two species each, which occur in the mainland part of Asia. The majority of the ''Loriculus'' species occur on islands. Moreover, since ''Loriculus'' is spread across both sides of the Wallace Line it can be consi ...

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 and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alexandrine Parakeet
The Alexandrine parakeet (''Psittacula eupatria''), also known as the Alexandrine parrot, is a medium-sized parrot in the genus Psittacula of the family Psittaculidae. It is named after Alexander the Great, who transported numerous birds from Punjab to various European and Mediterranean countries and regions, where they were prized by the royalty, nobility and warlords. The Alexandrine parakeet has established feral populations in Iraq, Kuwait Saudi Arabia, Bahrain, Qatar, the United Arab Emirates, Iran where it lives alongside feral populations of its close relative, the rose-ringed parakeet (''Psittacula krameri''). Taxonomy and etymology The Alexandrine parakeet was first described by French zoologist Mathurin Jacques Brisson as ''Psittaca Ginginiana'' or "La Perruche de Gingi" (The Gingi's Parakeet) in 1760; after the town of Gingee in southeastern India, which was a French outpost then. The birds may, however, merely have been held in captivity there. Carl Linnaeus redescrib ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lineolated Parakeet
The barred parakeet (''Bolborhynchus lineola''), also known as the lineolated parakeet or the Catherine parakeet, is a small parrot found disjunctly in highland forests from southern Mexico to Panama, in the Andes from western Venezuela to southern Peru and Bolivia, the Santa Marta Mountains in Colombia and the Venezuelan Coastal Range. Its plumage is mostly green with multiple black and dark green stripes or bars, and it has a pale-horn coloured beak. The dark stripes vary in prominence between its two subspecies. Several colour mutants are available in aviculture. Taxonomy There are two subspecies of the barred parakeet: *''Bolborhynchus lineola'' (Cassin 1853) **''Bolborhynchus lineola lineola'' (Cassin 1853) **''Bolborhynchus lineola tigrinus'' (Souance 1856) – which has more prominent dark stripes Description The barred parakeet is about 16 cm (6.5 in) in length and has a weight of about 42 to 52 grams.Forshaw (2006). plate 92.

Monk Parakeet
The monk parakeet (''Myiopsitta monachus''), also known as the Quaker parrot, is a species of true parrot in the family Psittacidae. It is a small, bright-green parrot with a greyish breast and greenish-yellow abdomen. Its average lifespan is 20–30 years. It originates from the temperate to subtropical areas of Argentina and the surrounding countries in South America. Self-sustaining feral populations occur in many places, mainly in North America and Europe. Taxonomy The monk parakeet was described by French polymath Georges-Louis Leclerc, Comte de Buffon, in 1780 in his ''Histoire Naturelle des Oiseaux''. The bird was also illustrated in a hand-coloured plate engraved by François-Nicolas Martinet in the ''Planches Enluminées D'Histoire Naturelle'', which was produced under the supervision of Edme-Louis Daubenton to accompany Buffon's text. Neither the plate caption nor Buffon's description included a scientific name, but in 1783, Dutch naturalist Pieter Boddaert coined the b ...

Brotogeris
''Brotogeris'' is a genus of small parrots endemic to Central and South America. Their closest relatives are the monk parakeet and the and the cliff parakeet in the genus '' Myiopsitta''. They eat seeds and fruit. The word ''brotogeris'' means "having the voice of a human". In the language of their native countries, which is mostly Spanish, they are called ''pericos'' – the translation of which is "parakeet". Their average lifespan is 15 years, although some have been reported to have lived up to 35 years. Also, the bird was found in Rio Grande do Sul in South America. Taxonomy The genus ''Brotogeris'' was introduced in 1825 by Irish zoologist Nicholas Aylward Vigors with the grey-cheeked parakeet as the type species. The name is from the Ancient Greek ''brotogērus'' meaning "with human voice". The genus contains eight species: * Tui parakeet, ''Brotogeris sanctithomae'' * Plain parakeet, ''Brotogeris tirica'' * White-winged parakeet, ''Brotogeris versicolorus'' * Yellow-c ...

Arini (tribe)
The Arini tribe of the neotropical parrots is a monophyletic clade of macaws and parakeets (commonly called conures in aviculture) characterized by colorful plumage and long, tapering tails. They occur throughout Mexico, Central America, and South America, and formerly the Caribbean and North America. One genus and several species are extinct; another genus is extinct in the wild. Two species are known only through subfossil remains. About a dozen hypothetical extinct species (see Extinct Caribbean macaws) have been described, native to the Caribbean area. Among the Arini are some of the rarest birds in the world, such as Spix's macaw, which is extinct in the wild – fewer than 100 specimens survive in captivity. It also contains the largest flighted parrot in the world, the hyacinth macaw. Some species, such as the blue-and-yellow macaw and sun conure are popular pet parrots. Molecular studies have dated the divergence of the Arini tribe from the ancestral neotropic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tribe (zoology)
In biology, a tribe is a taxonomic rank above genus, but below family and subfamily. It is sometimes subdivided into subtribes. By convention, all taxonomic ranks from genus upwards are capitalized, including both tribe and subtribe. In zoology, the standard ending for the name of a zoological tribe is "-ini". Examples include the tribes Caprini (goat-antelopes), Hominini (hominins), Bombini (bumblebees), and Thunnini (tunas). The tribe Hominini is divided into subtribes by some scientists; subtribe Hominina then comprises "humans". The standard ending for the name of a zoological subtribe is "-ina". In botany, the standard ending for the name of a botanical tribe is "-eae". Examples include the tribes Acalypheae and Hyacintheae. The tribe Hyacintheae is divided into subtribes, including the subtribe Massoniinae. The standard ending for the name of a botanical subtribe is "-inae". In bacteriology, the form of tribe names is as in botany, e.g., Pseudomonadeae, based on the genu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pyrrhura
''Pyrrhura'' (Greek Red/Fire Tail) is a genus of parrots in the Arini tribe. They occur in tropical and subtropical South America and southern Central America (Panama and Costa Rica). Most are restricted to humid forest and adjacent habitats, but one species, the blaze-winged parakeet, prefers deciduous or gallery woodland, and another, the Pfrimer's parakeet, is restricted to dry regions. Some species are highly endangered. Depending on the species, the total length range from . All have long, pointed tails, a mainly green plumage, and a relatively narrow, dark greyish to white eye-ring. Many have scaly or barred chest-patterns and a whitish, pale grey, buff or reddish ear-patch. They typically move around in small, noisy flocks, flying swiftly at or below canopy level. Once settled in a tree they tend to be silent (especially if aware of danger) and difficult to spot. They nest in a tree-crevice. Some species are popular in aviculture, where they are commonly referred to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aratinga
''Aratinga'' is a genus of South American conures. Most are predominantly green, although a few are predominantly yellow or orange. They are social and commonly seen in groups in the wild. In Brazil, the popular name of several species usually is ''jandaia'', sometimes written as ''jandaya'' in the scientific form. Many species from this genus are popular pets, although being larger than the members of the genus ''Pyrrhura'', they need a sizable aviary to thrive. Taxonomy The genus ''Aratinga'' was introduced in 1824 by the German naturalist Johann Baptist von Spix. The type species was subsequently designated as the sun parakeet. The genus name is from the extinct Tupi language of Brasil. ''Ará tinga'' means "bright bird" or "bright parrot". The taxonomy of this genus has recently been resolved by splitting it in four genera, as the genus as previously defined was paraphyletic. The species of the '' Aratinga solstitialis'' complex, were retained in this genus, while other form ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
