Binomial nomenclature called binominal nomenclature or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomen, binominal name or a scientific name; the first part of the name – the generic name – identifies the genus to which the species belongs, while the second part – the specific name or specific epithet – identifies the species within the genus. For example, humans belong within this genus to the species Homo sapiens. Tyrannosaurus rex is the most known binomial; the formal introduction of this system of naming species is credited to Carl Linnaeus beginning with his work Species Plantarum in 1753. But Gaspard Bauhin, in as early as 1623, had introduced in his book Pinax theatri botanici many names of genera that were adopted by Linnaeus; the application of binomial nomenclature is now governed by various internationally agreed codes of rules, of which the two most important are the International Code of Zoological Nomenclature for animals and the International Code of Nomenclature for algae and plants.
Although the general principles underlying binomial nomenclature are common to these two codes, there are some differences, both in the terminology they use and in their precise rules. In modern usage, the first letter of the first part of the name, the genus, is always capitalized in writing, while that of the second part is not when derived from a proper noun such as the name of a person or place. Both parts are italicized when a binomial name occurs in normal text, thus the binomial name of the annual phlox is now written as Phlox drummondii. In scientific works, the authority for a binomial name is given, at least when it is first mentioned, the date of publication may be specified. In zoology "Patella vulgata Linnaeus, 1758"; the name "Linnaeus" tells the reader who it was that first published a description and name for this species of limpet. "Passer domesticus". The original name given by Linnaeus was Fringilla domestica; the ICZN does not require that the name of the person who changed the genus be given, nor the date on which the change was made, although nomenclatorial catalogs include such information.
In botany "Amaranthus retroflexus L." – "L." is the standard abbreviation used in botany for "Linnaeus". "Hyacinthoides italica Rothm. – Linnaeus first named this bluebell species Scilla italica. The name is composed of two word-forming elements: "bi", a Latin prefix for two, "-nomial", relating to a term or terms; the word "binomium" was used in Medieval Latin to mean a two-term expression in mathematics. Prior to the adoption of the modern binomial system of naming species, a scientific name consisted of a generic name combined with a specific name, from one to several words long. Together they formed a system of polynomial nomenclature; these names had two separate functions. First, to designate or label the species, second, to be a diagnosis or description. In a simple genus, containing only two species, it was easy to tell them apart with a one-word genus and a one-word specific name; such "polynomial names" may sometimes look like binomials, but are different. For example, Gerard's herbal describes various kinds of spiderwort: "The first is called Phalangium ramosum, Branched Spiderwort.
The other... is aptly termed Phalangium Ephemerum Virginianum, Soon-Fading Spiderwort of Virginia". The Latin phrases are short descriptions, rather than identifying labels; the Bauhins, in particular Caspar Bauhin, took some important steps towards the binomial system, by pruning the Latin descriptions, in many cases to two words. The adoption by biologists of a system of binomial nomenclature is due to Swedish botanist and physician Carl von Linné, more known by his Latinized name Carl Linnaeus, it was in his 1753 Species Plantarum that he first began using a one-word "trivial name" together with a generic name in a system of binomial nomenclature. This trivial name is what is now known as specific name; the Bauhins' genus names were retained in many of these, but the descriptive part was reduced to a single word. Linnaeus's trivial names introduced an important new idea, namely that the function of a name could be to give a species a unique label; this meant. Thus Gerard's Phalangium ephemerum virginianum became Tradescantia virgi
A passerine is any bird of the order Passeriformes, which includes more than half of all bird species. Sometimes known as perching birds or – less – as songbirds, passerines are distinguished from other orders of birds by the arrangement of their toes, which facilitates perching. With more than 110 families and some 6,409 identified species, Passeriformes is the largest order of birds and among the most diverse orders of terrestrial vertebrates. Passerines are divided into three clades, Acanthisitti and Passeri; the passerines contain several groups of brood parasites such as the viduas, cuckoo-finches, the cowbirds. Most passerines are omnivorous; the terms "passerine" and "Passeriformes" are derived from the scientific name of the house sparrow, Passer domesticus, from the Latin term passer, which refers to sparrows and similar small birds. The order is divided into three suborders, Tyranni and the basal Acanthisitti. Oscines have the best control of their syrinx muscles among birds, producing a wide range of songs and other vocalizations.
The acanthisittids or New Zealand wrens are tiny birds restricted to New Zealand, at least in modern times. Most passerines are smaller than typical members of other avian orders; the heaviest and altogether largest passerines are the thick-billed raven and the larger races of common raven, each exceeding 1.5 kg and 70 cm. The superb lyrebird and some birds-of-paradise, due to long tails or tail coverts, are longer overall; the smallest passerine is the short-tailed pygmy tyrant, at 4.2 g. The foot of a passerine has three toes directed forward and one toe directed backward, called anisodactyl arrangement; this arrangement enables the passerine birds to perch upon vertical surfaces, such as trees and cliffs. The toes have no webbing or joining, but in some cotingas, the second and third toes are united at their basal third; the hind toe joins the leg at the same level as the front toes. The passeriformes have this toe arrangement in common with hunting birds like falcons; the leg arrangement of passerine birds contains a special adaptation for perching.
A tendon in the rear of the leg running from the underside of the toes to the muscle behind the tibiotarsus will automatically be pulled and tighten when the leg bends, causing the foot to curl and become stiff when the bird lands on a branch. This enables passerines to sleep. Most passerine birds develop 12 tail feathers, although the superb lyrebird has 16. Certain species of passerines have stiff tail feathers, which help the birds balance themselves when perching upon vertical surfaces; some passerines in the family Ploceidae, are well known for their elaborate sexual ornaments, including long tails. A well-known example is the long-tailed widowbird; the chicks of passerines are altricial: blind and helpless when hatched from their eggs. Hence, the chicks require extensive parental care. Most passerines lay coloured eggs, in contrast with nonpasserines, most of whose eggs are white except in some ground-nesting groups such as Charadriiformes and nightjars, where camouflage is necessary, in some parasitic cuckoos, which match the passerine host's egg.
Vinous-throated parrotbill has two egg colours and blue. This can prevent the brood parasitic Common cuckoo. Clutches vary in size: some larger passerines of Australia such as lyrebirds and scrub-robins lay only a single egg, most smaller passerines in warmer climates lay between two and five, while in the higher latitudes of the Northern Hemisphere, hole-nesting species like tits can lay up to a dozen and other species around five or six; the family Viduidae do not build their own nests, they lay eggs in other birds' nests. The evolutionary history of the passerine families and the relationships among them remained rather mysterious until the late 20th century. In many cases, passerine families were grouped together on the basis of morphological similarities that, it is now believed, are the result of convergent evolution, not a close genetic relationship. For example, the wrens of the Eurasia. Much research remains to be done, but advances in molecular biology and improved paleobiogeographical data are revealing a clearer picture of passerine origins and evolution that reconciles molecular affinities, the constraints of morphology and the specifics of the fossil record.
The first passerines are now thought to have evolved in the Southern Hemisphere in the late Paleocene or early Eocene, around 50 million years ago. The initial split was between the New Zealand wrens and all other passerines, the second split involved the Tyranni and the Passeri; the latter experienced a great radiation of forms out of the Australian continent. A major branch of the Passeri, parvorder Passerida, expanded deep into Eurasia and Africa, where a further explosive radiation of new lineages occurred; this led to three major Passerida lineages comprising about 4,000 species, which in addition to the Corvida and numerous minor linea
Systema Naturae is one of the major works of the Swedish botanist and physician Carl Linnaeus and introduced the Linnaean taxonomy. Although the system, now known as binomial nomenclature, was developed by the Bauhin brothers and Johann, 200 years earlier, Linnaeus was first to use it throughout his book; the first edition was published in 1735. The full title of the 10th edition, the most important one, was Systema naturæ per regna tria naturæ, secundum classes, genera, cum characteribus, synonymis, locis or translated: "System of nature through the three kingdoms of nature, according to classes, orders and species, with characters, synonyms, places"; the tenth edition of this book is considered the starting point of zoological nomenclature. In 1766 -- 1768 Linnaeus published the last under his authorship. Another again enhanced work in the same style and titled "Systema Naturae" was published by Johann Friedrich Gmelin between 1788 and 1793. Since at least the early 1900s zoologists recognized this as the last edition belonging to this series.
It was officially regarded by the ICZN in Opinion 296 as the 13th edition of Systema Naturae. Linnaeus published the first edition of Systema Naturae in the year 1735, during his stay in the Netherlands; as was customary for the scientific literature of its day, the book was published in Latin. In it, he outlined his ideas for the hierarchical classification of the natural world, dividing it into the animal kingdom, the plant kingdom, the "mineral kingdom". Linnaeus's Systema Naturae lists only about 10,000 species of organisms, of which about 6,000 are plants and 4,236 are animals. According to the historian of botany William T. Stearn, "Even in 1753 he believed that the number of species of plants in the whole world would hardly reach 10,000, his sexual system, where species with the same number of stamens were treated in the same group, was convenient but in his view artificial. Linnaeus believed in God's creation, that there were no deeper relationships to be expressed, he is quoted to have said: "God created, Linnaeus organized".
The classification of animals was more natural. For instance, humans were for the first time placed together as Anthropomorpha; as a result of the popularity of the work, the number of new specimens sent to him from around the world, Linnaeus kept publishing new and ever-expanding editions of his work. It grew from eleven large pages in the first edition to 2,400 pages in the 12th edition; as the work progressed, he made changes: in the first edition, whales were classified as fishes, following the work of Linnaeus' friend and "father of ichthyology" Peter Artedi. In this same edition, he introduced two-part names for animal species, something that he had done for plant species in the 1753 publication of Species Plantarum; the system developed into modern Linnaean taxonomy, a hierarchically organized biological classification. After Linnaeus' health declined in the early 1770s, publication of editions of Systema Naturae went in two directions. Another Swedish scientist, Johan Andreas Murray issued the Regnum Vegetabile section separately in 1774 as the Systema Vegetabilium, rather confusingly labelled the 13th edition.
Meanwhile, a 13th edition of the entire Systema appeared in parts between 1788 and 1793. It was as the Systema Vegetabilium that Linnaeus' work became known in England following translation from the Latin by the Lichfield Botanical Society, as A System of Vegetables. In his Imperium Naturæ, Linnaeus established three kingdoms, namely Regnum Animale, Regnum Vegetabile and Regnum Lapideum; this approach, the Animal and Mineral Kingdoms, survives until today in the popular mind, notably in the form of parlour games: "Is it animal, vegetable or mineral?". The classification was based on five levels: kingdom, order and species. While species and genus was seen as God-given, the three higher levels were seen by Linnaeus as constructs; the concept behind the set ranks being applied to all groups was to make a system, easy to remember and navigate, a task which most say he succeeded in. Linnaeus's work had a huge impact on science. Two of his works, the first edition of the Species Plantarum for plants and the 10th edition of the Systema Naturæ, are accepted among the starting points of nomenclature.
Most of his names for species and genera were published at early dates, thus take priority over those of other works. In zoology there is one exception, a monograph on Swedish spiders, Svenska Spindlar, published by Carl Clerck in 1757, so the names established there take priority over the Linnean names. However, his impact on science was not because of the value of his taxonomy, his talent for attracting skillful young students and sending them abroad to collect made his work far more influential than that of his contemporaries. At the close of the 18th century, his syste
Germany the Federal Republic of Germany, is a country in Central and Western Europe, lying between the Baltic and North Seas to the north, the Alps to the south. It borders Denmark to the north and the Czech Republic to the east and Switzerland to the south, France to the southwest, Luxembourg and the Netherlands to the west. Germany includes 16 constituent states, covers an area of 357,386 square kilometres, has a temperate seasonal climate. With 83 million inhabitants, it is the second most populous state of Europe after Russia, the most populous state lying in Europe, as well as the most populous member state of the European Union. Germany is a decentralized country, its capital and largest metropolis is Berlin, while Frankfurt serves as its financial capital and has the country's busiest airport. Germany's largest urban area is the Ruhr, with its main centres of Essen; the country's other major cities are Hamburg, Cologne, Stuttgart, Düsseldorf, Dresden, Bremen and Nuremberg. Various Germanic tribes have inhabited the northern parts of modern Germany since classical antiquity.
A region named Germania was documented before 100 AD. During the Migration Period, the Germanic tribes expanded southward. Beginning in the 10th century, German territories formed a central part of the Holy Roman Empire. During the 16th century, northern German regions became the centre of the Protestant Reformation. After the collapse of the Holy Roman Empire, the German Confederation was formed in 1815; the German revolutions of 1848–49 resulted in the Frankfurt Parliament establishing major democratic rights. In 1871, Germany became a nation state when most of the German states unified into the Prussian-dominated German Empire. After World War I and the revolution of 1918–19, the Empire was replaced by the parliamentary Weimar Republic; the Nazi seizure of power in 1933 led to the establishment of a dictatorship, the annexation of Austria, World War II, the Holocaust. After the end of World War II in Europe and a period of Allied occupation, Austria was re-established as an independent country and two new German states were founded: West Germany, formed from the American and French occupation zones, East Germany, formed from the Soviet occupation zone.
Following the Revolutions of 1989 that ended communist rule in Central and Eastern Europe, the country was reunified on 3 October 1990. Today, the sovereign state of Germany is a federal parliamentary republic led by a chancellor, it is a great power with a strong economy. As a global leader in several industrial and technological sectors, it is both the world's third-largest exporter and importer of goods; as a developed country with a high standard of living, it upholds a social security and universal health care system, environmental protection, a tuition-free university education. The Federal Republic of Germany was a founding member of the European Economic Community in 1957 and the European Union in 1993, it is part of the Schengen Area and became a co-founder of the Eurozone in 1999. Germany is a member of the United Nations, NATO, the G7, the G20, the OECD. Known for its rich cultural history, Germany has been continuously the home of influential and successful artists, musicians, film people, entrepreneurs, scientists and inventors.
Germany has a large number of World Heritage sites and is among the top tourism destinations in the world. The English word Germany derives from the Latin Germania, which came into use after Julius Caesar adopted it for the peoples east of the Rhine; the German term Deutschland diutisciu land is derived from deutsch, descended from Old High German diutisc "popular" used to distinguish the language of the common people from Latin and its Romance descendants. This in turn descends from Proto-Germanic *þiudiskaz "popular", derived from *þeudō, descended from Proto-Indo-European *tewtéh₂- "people", from which the word Teutons originates; the discovery of the Mauer 1 mandible shows that ancient humans were present in Germany at least 600,000 years ago. The oldest complete hunting weapons found anywhere in the world were discovered in a coal mine in Schöningen between 1994 and 1998 where eight 380,000-year-old wooden javelins of 1.82 to 2.25 m length were unearthed. The Neander Valley was the location where the first non-modern human fossil was discovered.
The Neanderthal 1 fossils are known to be 40,000 years old. Evidence of modern humans dated, has been found in caves in the Swabian Jura near Ulm; the finds included 42,000-year-old bird bone and mammoth ivory flutes which are the oldest musical instruments found, the 40,000-year-old Ice Age Lion Man, the oldest uncontested figurative art discovered, the 35,000-year-old Venus of Hohle Fels, the oldest uncontested human figurative art discovered. The Nebra sky disk is a bronze artefact created during the European Bronze Age attributed to a site near Nebra, Saxony-Anhalt, it is part of UNESCO's Memory of the World Programme. The Germanic tribes are thought to date from the Pre-Roman Iron Age. From southern Scandinavia and north Germany, they expanded south and west from the 1st century BC, coming into contact with the Celtic tribes of Gaul as well
The Middle East is a transcontinental region centered on Western Asia and Egypt. Saudi Arabia is geographically the largest Middle Eastern nation; the corresponding adjective is Middle Eastern and the derived noun is Middle Easterner. The term has come into wider usage as a replacement of the term Near East beginning in the early 20th century. Arabs, Persians and Azeris constitute the largest ethnic groups in the region by population. Arabs constitute the largest ethnic group in the region by a clear margin. Indigenous minorities of the Middle East include Jews, Assyrians, Copts, Lurs, Samaritans, Shabaks and Zazas. European ethnic groups that form a diaspora in the region include Albanians, Circassians, Crimean Tatars, Franco-Levantines, Italo-Levantines. Among other migrant populations are Chinese, Indians, Pakistanis, Pashtuns and sub-Saharan Africans; the history of the Middle East dates back to ancient times, with the importance of the region being recognized for millennia. Several major religions have their origins in the Middle East, including Judaism and Islam.
The Middle East has a hot, arid climate, with several major rivers providing irrigation to support agriculture in limited areas such as the Nile Delta in Egypt, the Tigris and Euphrates watersheds of Mesopotamia, most of what is known as the Fertile Crescent. Most of the countries that border the Persian Gulf have vast reserves of crude oil, with monarchs of the Arabian Peninsula in particular benefiting economically from petroleum exports; the term "Middle East" may have originated in the 1850s in the British India Office. However, it became more known when American naval strategist Alfred Thayer Mahan used the term in 1902 to "designate the area between Arabia and India". During this time the British and Russian Empires were vying for influence in Central Asia, a rivalry which would become known as The Great Game. Mahan realized not only the strategic importance of the region, but of its center, the Persian Gulf, he labeled the area surrounding the Persian Gulf as the Middle East, said that after Egypt's Suez Canal, it was the most important passage for Britain to control in order to keep the Russians from advancing towards British India.
Mahan first used the term in his article "The Persian Gulf and International Relations", published in September 1902 in the National Review, a British journal. The Middle East, if I may adopt a term which I have not seen, will some day need its Malta, as well as its Gibraltar. Naval force has the quality of mobility; the British Navy should have the facility to concentrate in force if occasion arise, about Aden and the Persian Gulf. Mahan's article was reprinted in The Times and followed in October by a 20-article series entitled "The Middle Eastern Question," written by Sir Ignatius Valentine Chirol. During this series, Sir Ignatius expanded the definition of Middle East to include "those regions of Asia which extend to the borders of India or command the approaches to India." After the series ended in 1903, The Times removed quotation marks from subsequent uses of the term. Until World War II, it was customary to refer to areas centered around Turkey and the eastern shore of the Mediterranean as the "Near East", while the "Far East" centered on China, the Middle East meant the area from Mesopotamia to Burma, namely the area between the Near East and the Far East.
In the late 1930s, the British established the Middle East Command, based in Cairo, for its military forces in the region. After that time, the term "Middle East" gained broader usage in Europe and the United States, with the Middle East Institute founded in Washington, D. C. in 1946, among other usage. The description Middle has led to some confusion over changing definitions. Before the First World War, "Near East" was used in English to refer to the Balkans and the Ottoman Empire, while "Middle East" referred to Iran, the Caucasus, Central Asia, Turkestan. In contrast, "Far East" referred to the countries of East Asia With the disappearance of the Ottoman Empire in 1918, "Near East" fell out of common use in English, while "Middle East" came to be applied to the re-emerging countries of the Islamic world. However, the usage "Near East" was retained by a variety of academic disciplines, including archaeology and ancient history, where it describes an area identical to the term Middle East, not used by these disciplines.
The first official use of the term "Middle East" by the United States government was in the 1957 Eisenhower Doctrine, which pertained to the Suez Crisis. Secretary of State John Foster Dulles defined the Middle East as "the area lying between and including Libya on the west and Pakistan on the east and Iraq on the North and the Arabian peninsula to the south, plus the Sudan and Ethiopia." In 1958, the State Department explained that the terms "Near East" and "Middle East" were interchangeable, defined the region as including only Egypt, Israel, Jordan, Saudi Arabia, Kuwait and Qatar.

Isfahan is a city in Iran. It is located 406 kilometres south of Tehran, is the capital of Isfahan Province. Isfahan has a population of 1.6 million, making it the third largest city in Iran after Tehran and Mashhad, but was once one of the largest cities in the world. Isfahan is an important city as it is located at the intersection of the two principal north–south and east–west routes that traverse Iran. Isfahan flourished from 1050 to 1722 in the 16th and 17th centuries under the Safavid dynasty when it became the capital of Persia for the second time in its history under Shah Abbas the Great. Today the city retains much of its past glory, it is famous for its Perso–Islamic architecture, grand boulevards, covered bridges, tiled mosques, minarets. Isfahan has many historical buildings, monuments and artefacts; the fame of Isfahan led to the Persian pun and proverb "Esfahān nesf-e- jahān ast": Isfahan is half the world. The Naghsh-e Jahan Square in Isfahan is one of the largest city squares in the world.
UNESCO has designated it a World Heritage Site. See also: Names of Isfahan"Isfahan" is derived from Middle Persian Spahān. Spahān is attested in various Middle Persian seals and inscriptions, including that of Zoroastrian Magi Kartir, is the Armenian name of the city; the present-day name is the Arabicized form of Ispahan. The region appears with the abbreviation GD on Sasanian numismatics. In Ptolemy's Geographia it appears as Aspadana, translating to "place of gathering for the army", it is believed. Human habitation of the Isfahan region can be traced back to the Palaeolithic period. Recent discoveries archaeologists have found artifacts dating back to the Palaeolithic, Neolithic and Iron ages. What was to become the city of Isfahan in historical periods emerged as a locality and settlement that developed over the course of the Elamite civilisation. Under Median rule, this commercial entrepôt began to show signs of a more sedentary urbanism growing into a noteworthy regional centre that benefited from the exceptionally fertile soil on the banks of the Zayandehrud River in a region called Aspandana or Ispandana.
Once Cyrus the Great had unified Persian and Median lands into the Achaemenid Empire, the religiously and ethnically diverse city of Isfahan became an early example of the king's fabled religious tolerance. It was Cyrus who, having just taken Babylon, made an edict in 538 BCE, declaring that the Jews in Babylon could return to Jerusalem. Now it seems that some of these freed Jews settled in Isfahan instead of returning to their homeland; the 10th-century Persian historian Ibn al-Faqih wrote:"When the Jews emigrated from Jerusalem, fleeing from Nebuchadnezzar, they carried with them a sample of the water and soil of Jerusalem. They did not settle down anywhere or in any city without examining the water and the soil of each place, they did all along. There they rested, found that both resembled Jerusalem. Thereupon they settled there, cultivated the soil, raised children and grandchildren, today the name of this settlement is Yahudia." The Parthians in the period 250–226 BCE continued the tradition of tolerance after the fall of the Achaemenids, fostering the Hellenistic dimension within Iranian culture and the political organisation introduced by Alexander the Great's invading armies.
Under the Parthians, Arsacid governors administered the provinces of the nation from Isfahan, the city's urban development accelerated to accommodate the needs of a capital city. The next empire to rule Persia, the Sassanids, presided over massive changes in their realm, instituting sweeping agricultural reform and reviving Iranian culture and the Zoroastrian religion. Both the city and region were called by the name Aspahan or Spahan; the city was governed by a group called the Espoohrans, who came from seven noble and important Iranian royal families. Extant foundations of some Sassanid-era bridges in Isfahan suggest that the Sasanian kings were fond of ambitious urban planning projects. While Isfahan's political importance declined during the period, many Sassanid princes would study statecraft in the city, its military role developed rapidly, its strategic location at the intersection of the ancient roads to Susa and Persepolis made it an ideal candidate to house a standing army, ready to march against Constantinople at any moment.
The words'Aspahan' and'Spahan' are derived from the Pahlavi or Middle Persian meaning'the place of the army'. Although many theories have been mentioned about the origin of Isfahan, in fact little is known of it before the rule of the Sasanian dynasty; the historical facts suggest that in the late 4th and early 5th centuries, Queen Shushandukht, the Jewish consort of Yazdegerd I settled a colony of Jews in Yahudiyyeh, a settlement 3 km northwest of the Zoroastrian city of Gabae (its Achaemid and Parthian name. The gradual population decrease of Gay and the simultaneous population increase of Yahudiyyeh and its suburbs
Richard Bowdler Sharpe
Richard Bowdler Sharpe was an English zoologist and ornithologist who worked as curator of the bird collection at the British Museum of natural history. In the course of his career he published several monographs on bird groups and produced a multi-volume catalogue of the specimens in the collection of the museum, he described several new species of bird including Sharpe's longclaw and Sharpe's pied-babbler which are named in his honour. Richard was born in the first son of Thomas Bowdler Sharpe, his grandfather, Reverend Lancelot Sharpe was Rector of All Hallows Staining. His father was a publisher on Skinner Street and was best known for being the publisher of Sharpe's London Magazine, an illustrated periodical, his care from the age of six was under an aunt, Magdalen Wallace, widow of the headmaster at Grammar School in Sevenoaks and went to school in Brighton. At nine he studied at Peterborough receiving a King's Scholarship, he moved to Loughborough Grammar School. He worked as a clerk with W. H. Smith & Sons.
He took an interest in ornithology and was interested in writing a monograph on the kingfishers. After two years, in 1865, he joined the company of the bookseller Bernard Quaritch and had an opportunity to examine ornithological books and began to work in earnest on his monograph, purchasing specimens of kingfishers from a meagre income. At nineteen, in 1867, he became a librarian at the Zoological Society of London on the recommendation of Osbert Salvin and Philip Sclater and he completed his Monograph of the Kingfishers during this period; the book was produced in parts with 121 illustrations. He began to collaborate with Henry Dresser on A History of the Birds of Europe but this had to be abandoned because of his new appointment. On the death of George Robert Gray in 1872 he joined the British Museum as a Senior Assistant in the Department of Zoology, taking charge of the bird collection. On December 3, 1867 he married Emily Eliza, daughter of J. W. Burrows of Cookham dedicating Tanysiptera galatea emiliae to her in 1871.
They had ten daughters and many of them contributed to his books by hand colouring the lithograph plates. One daughter, Emily Mary, worked in the entomology department of the Natural History Museum between 1905 and 1925, he became Assistant Keeper in 1895, a position he held until his death from pneumonia in 1909. He died at his home in Chiswick. In 1911 a ₤100 civil pension was granted to his wife and daughters Emily Mary, Ada Lavinia and Eva Augusta; as curator of the bird collections, Sharpe's main work was in classifying and cataloguing the collections. He played a major role in acquiring private collections by persuading wealthy collectors and travellers to contribute to the museum. In 1872 the museum had 35,000 bird specimens; these included the bequests of Allan Octavian Hume, Osbert Salvin and Frederick DuCane Godman, the industrialist and amateur ornithologist Henry Seebohm, Colonel John Biddulph, C. B. Rickett, F. W. Styan, Alfred Russel Wallace, George Ernest Shelley, Philip Sclater and the bird illustrator John Gould.
Sharpe edited its bulletin. He wrote a half of the 27 volumes of the Catalogue of the Birds in the British Museum, his handsome Birds of Paradise, published in two large volumes in 1891 and 1898, presented these colourful birds to the world: as Sharpe wrote in his preface, "a great number of the species are here figured for the first time". Sharpe was nominated at the International Ornithological Congress at Paris in 1900 to preside over the London Congress in 1905. Sharpe was noted as a humorous person. Richard Meinertzhagen and his brother were introduced to the bird collections by him, he was fond of children. He was known for his practical jokes and pranks; when Eugene Oates was working on the Fauna of British India, he found the notes lying on a table and filled up a stray statement on the call of a white wagtail which went into print. On one occasion, Sharpe ascended the Eiffel tower with friends but became hysterical on reaching the top, with Ernst Hartert and several others having to restrain him and prevent him from jumping off.
A regular at the Savage and Whitefriars Club, he and his wife threw a party in February 1888 with 120 guests and entertainment that included humorous sketches, songs and music. Sharpe was awarded an honorary LL. D. by the University of Aberdeen. He was the Zoological Society of London. A gold medal was awarded to him in 1891 by the Emperor of Austria. Many species and subspecies of birds have been named after him including: Sharpe's Apalis a subspecies of the piping hornbill Sharpe's starling the Burmese subspecies of the sarus crane the Iberian green woodpecker Sharpe's akalat the black-lored or Sharpe's pied-babbler.
