Intermediate Parakeet
The intermediate parakeet (''Psittacula intermedia'') or Rothschild's parakeet was a kind of parakeet reported from the sub-Himalayan region of India and was described on the basis of about seven undated specimens. Similar individuals have been noted in captivity and the type specimen is now believed to be a hybrid between '' Psittacula himalayana'' and '' Psittacula cyanocephala''. More recent captive specimens that appeared similar were found to be hybrids produced by crosses between ''Psittacula krameri 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 Psittacidae. It has disjunct na ...'' and '' Psittacula cyanocephala''. An analysis of the characters of the specimens suggests that the originally described ''P. intermedia'' was a hybrid between ''P. cyanocephala'' x ''P. himalayana''.Rasmussen, P. C. & N. J. Coll ...

Walter Rothschild, 2nd Baron Rothschild
Lionel Walter Rothschild, 2nd Baron Rothschild, Baron de Rothschild, (8 February 1868 – 27 August 1937) was a British banker, politician, zoology, zoologist, and soldier, who was a member of the Rothschild family. As a Zionist leader, he was presented with the Balfour Declaration, which pledged United Kingdom, British support for a Jewish national home in Palestine (region), Mandatory Palestine. Rothschild was the president of the Board of Deputies of British Jews from 1925 to 1926. Early life Walter Rothschild was born in London as the eldest son and heir of Emma Louise von Rothschild and Nathan Rothschild, 1st Baron Rothschild, an immensely wealthy financier of the international Rothschild financial dynasty and the first Jewish Peerage, peer in England.

Psittacula Himalayana
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 ...

Psittacula Cyanocephala
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 Internatio ...

Trichoglossus Haematodus Subsp
''Trichoglossus'' is a genus of lorikeet in the Psittaculidae or true parrot superfamily. The genus is distributed widely through Australia, Wallacea and Melanesia, with outliers in the Philippines and Micronesia. Members of the genus are characterised by barring, sometimes prominently, on the upper breast. Taxonomy The genus ''Trichoglossus'' was introduced in 1826 by the English naturalist James Francis Stephens. The name combines the Ancient Greek ''thrix'' meaning "hair" and ''glōssa'' meaning "tongue". The type species was subsequently designated as the coconut lorikeet. Following the publication of a molecular phylogenetic study of the lorikeets in 2020, three species were moved from ''Trichoglossus '' to the newly erected genus ''Saudareos''. These were the Mindanao lorikeet, the ornate lorikeet and the Sula lorikeet (formerly the citrine lorikeet). Species The genus contains ten species: ''Trichoglossus'' sensu lato The Clements taxonomy place ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
India
India, officially the Republic of India, is a country in South Asia. It is the List of countries and dependencies by area, seventh-largest country by area; the List of countries by population (United Nations), most populous country since 2023; and, since its independence in 1947, the world's most populous democracy. Bounded by the Indian Ocean on the south, the Arabian Sea on the southwest, and the Bay of Bengal on the southeast, it shares land borders with Pakistan to the west; China, Nepal, and Bhutan to the north; and Bangladesh and Myanmar to the east. In the Indian Ocean, India is near Sri Lanka and the Maldives; its Andaman and Nicobar Islands share a maritime border with Thailand, Myanmar, and Indonesia. Modern humans arrived on the Indian subcontinent from Africa no later than 55,000 years ago., "Y-Chromosome and Mt-DNA data support the colonization of South Asia by modern humans originating in Africa. ...

Type Specimen
In biology, a type is a particular wikt:en:specimen, specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally associated. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set (mathematics), set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the ''International Code of Nomenclature for algae, fungi, and plants'' (ICN), the ...

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different varieties, subspecies, species or genera through sexual reproduction. Generally, it means that each cell has genetic material from two different organisms, whereas an individual where some cells are derived from a different organism is called a chimera. Hybrids are not always intermediates between their parents such as in blending inheritance (a now discredited theory in modern genetics by particulate inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridization, which include genetic and morph ...

Psittacula Krameri
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 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, 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 Conservation of Nature (IUCN) because ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parakeets
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 word ''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'') ref ...

Psittacula
''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 p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bird Hybrids
A bird hybrid is a bird that has two different species as parents. The resulting bird can present with any combination of characteristics from the parent species, from totally identical to completely different. Usually, the bird hybrid shows intermediate characteristics between the two species. A "successful" hybrid is one demonstrated to produce fertile offspring. According to the most recent estimates, about 16% of all wild bird species have been known to hybridize with one another; this number increases to 22% when captive hybrids are taken into account. Several bird species hybridize with multiple other species. For example, the mallard (''Anas platyrhynchos'') is known to interbreed with at least 40 different species. The ecological and evolutionary consequences of multispecies hybridization remain to be determined. In the wild, some of the most frequently reported hybrids are waterfowl, gulls, hummingbirds, and birds-of-paradise. Mallards, whether of wild or domestic o ...
