Alexandrinus (genus)
''Psittacula'', also known as Afro-Asian ring-necked parrots, is a genus of parrots from Africa and Southeast 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 considered more Australasian than Asian. These ...

Rose-ringed Parakeet
The rose-ringed parakeet (''Psittacula krameri''), also known as the ring-necked parakeet, ringneck parrot (in aviculture) or the Kramer parrot, is a medium-sized parrot in the genus ''Psittacula'', of the Family (biology), family Psittacidae. It has disjunct native ranges in Africa and the Indian subcontinent, and is now introduced into many other parts of the world where feral populations have established themselves or are bred for the exotic pet trade. One of the few parrot species that have successfully adapted to living in disturbed habitats, it has withstood the onslaught of urbanization and deforestation. As a popular pet species, feral parrot, escaped birds have colonised a number of cities around the world, including populations in Northern and Western Europe. They can live in a variety of climates outside their native range, and are able to survive low winter temperatures in Northern Europe. The species is listed as least concern by the International Union for Conservat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type Species
In International_Code_of_Zoological_Nomenclature, zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological Type (biology), type wiktionary:en:specimen, specimen (or specimens). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the International Code of Nomenclature for algae, fungi, and plants, code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name with that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have suc ...

Slaty-headed Parakeet
The slaty-headed parakeet (''Psittacula himalayana'') is the only psittacid species to exhibit altitudinal migration. The species' range extends from Pakistan, to Western Himalayas in India through Nepal and Bhutan and up to the Eastern Himalayas in the northeastern Indian state of Arunachal Pradesh. They descend to the valleys in winter, approximately during the last week of October. Description Adults of both sexes have green (tinted with blue) feathers on most of their body. It has a dark grey (slate colored) head with a light blue tint where head meets the neck. Males feature dark maroon patches on inner wing coverts. Females do not feature these maroon patches. Males have long central tail feathers which are shorter in female birds. The tail is green at base and becomes deep blue and widely tipped with bright yellow. The parakeet features a bright red-orange upper mandible with a pale yellow lower. It also has a pale yellow eye. Distribution and population The slaty-head ...

Blossom-headed Parakeet
The Blossom-headed parakeet, ''Psittacula roseata'' or ''Himalayapsitta roseata,'' is a parrot in the family Psittaculidae. It has a lime green body and a pink or bluish grey-head and is found in Southeast Asia. This species is sometimes also referred to as Rosy-headed parakeet. Description ''Psittacula roseata'' is a lime-green parrot, long with a tail up to . It weighs on average 2.9 - 3.1 oz (85 - 90 g). The male's head, cheeks, and ears are pink becoming pale blue towards the back of the crown and nape. There is a narrow black neck collar and a black chin stripe. There is a reddish brown shoulder spot on the inner middle wing coverts. Long, central tail feathers are blue and tipped with pale yellow. Side tail feathers are yellow green and tipped with pale yellow. The upper mandible is orange yellow, and the lower mandible is a dark grey. Eyes are pale yellow. The female ''Psittacula roseata'' differs with a pale blue grey head and the black neck collar is instead yellow gre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plum-headed Parakeet
The plum-headed parakeet (''Psittacula cyanocephala'') is a species of parakeet in the family Psittacidae. It is endemic to the Indian Subcontinent and was once thought to be conspecific with the blossom-headed parakeet (''P. roseata'') before being elevated to a full species. Plum-headed parakeets are found in flocks, the males having a pinkish purple head and the females, a grey head. They fly swiftly with twists and turns accompanied by their distinctive calls. Taxonomy In 1760 the French zoologist Mathurin Jacques Brisson included a description of the plum-headed parakeet in his ''Ornithologie'' based on a specimen collected in India. He used the French name ''Le perruche a teste bleu'' and the Latin name ''Psittaca cyanocephalos''. The two stars (**) at the start of the section indicates that Brisson based his description on the examination of a specimen. Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the Internati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seychelles Parakeet
The Seychelles parakeet or Seychelles Island parrot (''Psittacula wardi'') is an extinct species of parrot that was endemic to the Seychelles in the Indian Ocean. It was scientifically named ''Palaeornis wardi'' by the British ornithologist Edward Newton in 1867, and the specific name honours the British civil commissioner Swinburne Ward who procured the specimens that formed the basis for the description. It was found on the islands of Mahé, Silhouette, and possibly Praslin. Ten skin specimens exist today, but no skeletons. Though the species was later moved to the genus ''Psittacula'', genetic studies have led some researchers to suggest it should belong in a reinstated '' Palaeornis'' along with the closely related Alexandrine parakeet (''P. eupatria'') of Asia. This parakeet was about in length, with a long, pointed tail. The male was mainly green, with blue on parts of the head, and a black stripe on the cheek. The underside was yellowish, and the bird had a purple ... [...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, native to South Asia and Southeast Asia. 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 Turkey, Iraq, Kuwait, Saudi Arabia, Bahrain, Qatar, the United Arab Emirates, Iran, and Pakistan, 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, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mascarene Grey Parakeet
The Mascarene grey parakeet, Mauritius grey parrot, or Thirioux's grey parrot (''Psittacula bensoni''), is an extinct species of parrot which was endemic to the Mascarene Islands of Mauritius and Réunion in the western Indian Ocean. It has been classified as a member of the tribe Psittaculini, along with other parrots from the Islands. Subfossil bones of the Mascarene grey parakeet found on Mauritius were first described in 1973 as belonging to a smaller relative of the broad-billed parrot in the genus ''Lophopsittacus''. Apart from their size, the bones were very similar to those of other Mascarene parrots. The subfossils were later connected with 17th- and 18th-century descriptions of small grey parrots on Mauritius and Réunion, together with a single illustration published in a journal describing a voyage in 1602, and the species was instead reassigned to the genus ''Psittacula''. The Mascarene grey parakeet was grey, had a long tail, and was larger than other species of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Réunion Parrot
The Rodrigues parrot or Leguat's parrot (''Necropsittacus rodricanus'') is an extinct species of parrot that was endemism in birds, endemic to the Mascarene island of Rodrigues. The species is known from subfossil bones and from mentions in contemporary accounts. It is unclear to which other species it is most closely related, but it is classified as a member of the Tribe (biology), tribe Psittaculini, along with other Mascarene parrots. The Rodrigues parrot bore similarities to the broad-billed parrot of Mauritius, and may have been related. Two additional species have been assigned to its genus (''N. francicus'' and ''N. borbonicus''), based on descriptions of parrots from the other Mascarene islands, but their identities and validity have been debated. The Rodrigues parrot was green, and had a proportionally large head and beak and a long tail. Its exact size is unknown, but it may have been around long. It was the largest parrot on Rodrigues, and it had the largest head of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Echo Parakeet
The echo parakeet (''Psittacula eques'') is a species of parrot endemic to the Mascarene Islands of Mauritius and formerly Réunion. It is the only living native parrot of the Mascarene Islands; all others have become extinct due to human activity. Two subspecies have been recognised, the extinct Réunion parakeet (for a long time known only from descriptions and illustrations) and the living echo parakeet, sometimes known as the Mauritius parakeet. The relationship between the two populations was historically unclear, but a 2015 DNA study determined them to be subspecies of the same species by comparing the DNA of echo parakeets with a single skin thought to be from a Réunion parakeet, but it has also been suggested they did not constitute different subspecies. As it was named first, the binomial name of the Réunion parakeet is used for the species; the Réunion subspecies thereby became ''P. eques eques'', while the Mauritius subspecies became ''P. eques echo''. Their closest r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extinct
Extinction is the termination of an organism by the death of its Endling, last member. A taxon may become Functional extinction, functionally extinct before the death of its last member if it loses the capacity to Reproduction, reproduce and recover. As a species' potential Range (biology), range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxon, Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the Fossil, fossil record) after a period of apparent absence. Over five billion species are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryotes globally, possibly many times more if microorganisms are included. Notable extinct animal species include Dinosaur, non-avian dinosaurs, Machairodontinae, saber-toothed cats, and mammoths. Through evolution, species arise through the process of specia ...
