Plum-headed Parakeet
The plum-headed parakeet (''Psittacula cyanocephala'') is a parakeet in the family Psittacidae. It is endemic to the Indian Subcontinent and was once thought to be conspecific with the blossom-headed parakeet (''Psittacula roseata'') but was later 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 Internationa ...

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ctesias Of Cnidus
Ctesias (; grc-gre, Κτησίας; fl. fifth century BC), also known as Ctesias of Cnidus, was a Greek physician and historian from the town of Cnidus in Caria, then part of the Achaemenid Empire. Historical events Ctesias, who lived in the fifth century BC, was physician to the Achaemenid king, Artaxerxes II, whom he accompanied in 401 BC on his expedition against his brother Cyrus the Younger. Ctesias was part of the entourage of King Artaxerxes at the Battle of Cunaxa (401 BC) against Cyrus the Younger and his Greek mercenaries called the Ten Thousand, when Ctesias provided medical assistance to the king by treating his flesh wound. He reportedly was involved in negotiations with the Greeks after the battle, and also helped their Spartan general Clearchus before his execution at the royal court at Babylon. Ctesias was the author of treatises on rivers and on the Persian revenues as well as an account of India entitled '' Indica'' (Ἰνδικά), and of a history of Assyria ...

Haemoproteus
''Haemoproteus'' is a genus of alveolates that are parasitic in birds, reptiles and amphibians. Its name is derived from Greek: ''Haima'', "blood", and ''Proteus'', a sea god who had the power of assuming different shapes. The name ''Haemoproteus'' was first used in the description of '' H. columbae'' in the blood of the pigeon ''Columba livia'' by Kruse in 1890. This was also the first description of this genus. Two other genera — '' Halteridium'' and '' Simondia'' — are now considered to be synonyms of ''Haemoproteus''. The protozoa are intracellular parasites that infect the erythrocytes. They are transmitted by blood sucking insects including mosquitoes, biting midges (''Culicoides''), louse flies (''Hippoboscidae'') and horse-flies (" tabanids", "tabanid flies"). Infection with this genus is sometimes known as pseudomalaria because of the parasites' similarities with ''Plasmodium'' species. Within the genus there are at least 173 species, 5 varieties and 1 subspecies. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mite
Mites are small arachnids (eight-legged arthropods). Mites span two large orders of arachnids, the Acariformes and the Parasitiformes, which were historically grouped together in the subclass Acari, but genetic analysis does not show clear evidence of a close relationship. Most mites are tiny, less than in length, and have a simple, unsegmented body plan. The small size of most species makes them easily overlooked; some species live in water, many live in soil as decomposers, others live on plants, sometimes creating galls, while others again are Predation, predators or Parasitism, parasites. This last type includes the commercially destructive ''Varroa'' parasite of honey bees, as well as scabies mites of humans. Most species are harmless to humans, but a few are associated with allergies or may transmit diseases. The scientific discipline devoted to the study of mites is called acarology. Evolution and taxonomy The mites are not a defined taxon, but is used for two disti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Egg Incubation
Egg incubation is the process by which an egg, of oviparous (egg-laying) animals, develops an embryo within the egg, after the egg's formation and ovipositional release. Egg incubation is done under favorable environmental conditions, possibly by brooding and hatching the egg. Multiple and various factors are vital to the incubation of various species of animal. In many species of reptile for example, no fixed temperature is necessary, but the actual temperature determines the sex ratio of the offspring. In birds in contrast, the sex of offspring is genetically determined, but in many species a constant and particular temperature is necessary for successful incubation. Especially in poultry, the act of sitting on eggs to incubate them is called brooding. The action or behavioral tendency to sit on a clutch of eggs is also called broodiness, and most egg-laying breeds of poultry have had this behavior selectively bred out of them to increase production. Avian incubation A wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Courtship Feeding
A nuptial gift is a nutritional gift given by one partner in some animals' sexual reproduction practices. Formally, a nuptial gift is a material presentation to a recipient by a donor during or in relation to sexual intercourse that is not simply gametes in order to improve the reproductive fitness of the donor. Often, such a gift will improve the fitness of the recipient as well. This definition implies neutral gifts, costly gifts and beneficial gifts regarding the fitness of the recipient. Nuptial gifting is at the intersection of sexual selection, nutritional ecology, and life history theory, creating a link between the three. Edible and inedible nuptial gifts Many nuptial gifts are a source of nutrition for the recipient. In many species of animals, including birds, insects, and spiders, this takes the form of a food item that is transferred from a male to a female just prior to copulation. This is a behavior known as courtship feeding. Inedible tokens may include item ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plum Headed Parakeet
A plum is a fruit of some species in ''Prunus'' subg. ''Prunus''''.'' Dried plums are called prunes. History Plums may have been one of the first fruits domesticated by humans. Three of the most abundantly cultivated species are not found in the wild, only around human settlements: ''Prunus domestica'' has been traced to East European and Caucasian mountains, while ''Prunus salicina'' and ''Prunus simonii'' originated in China. Plum remains have been found in Neolithic age archaeological sites along with olives, grapes and figs. According to Ken Albala, plums originated in Iran. They were brought to Britain from Asia. An article on plum tree cultivation in Andalusia (southern Spain) appears in Ibn al-'Awwam's 12th-century agricultural work, ''Book on Agriculture''. Etymology and names The name plum derived from Old English ''plume'' "plum, plum tree", borrowed from Germanic or Middle Dutch, derived from Latin ' and ultimately from Ancient Greek ''proumnon'', itself believ ...

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 genders 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-h ...

Psittacula Intermedia
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'' and ''Psittacula cyanocephala The plum-headed parakeet (''Psittacula cyanocephala'') is a parakeet in the family Psittacidae. It is endemic to the Indian Subcontinent and was once thought to be conspecific with the blossom-headed parakeet (''Psittacula roseata'') but was late ...''.
