Tetri
–
Tetri is a fractional currency used in the country of Georgia. It was put into circulation in 1995, the name tetri was adopted from the term describing golden, silver or copper coins known in ancient and medieval Georgia. The plural of the term tetri is tetrebi, however, the Georgian language uses the singular form when the quantity is specified, so in practice the plural of tetri is just tetri. Modern coins minted in the Republic of Georgia

Georgia (country)
–
Georgia is a country in the Caucasus region of Eurasia. The capital and largest city is Tbilisi, Georgia covers a territory of 69,700 square kilometres, and its 2016 population is about 3.72 million. Georgia is a unitary, semi-presidential republic, with the government elected through a representative democracy, during the classical era, several independent kingdoms became established in what is now Georgia. The kingdoms of Colchis and Iberia adopted Christianity in the early 4th century, a unified Kingdom of Georgia reached the peak of its political and economic strength during the reign of King David IV and Queen Tamar in the 12th and early 13th centuries. Thereafter the kingdom declined and eventually disintegrated under hegemony of various powers, including the Mongols, the Ottoman Empire. Russian rule over Georgia was eventually acknowledged in various treaties with Iran. Since the establishment of the modern Georgian republic in April 1991, post-communist Georgia suffered from civil, the countrys Western orientation soon led to the worsening of relations with Russia, culminating in the brief Russo-Georgian War in August 2008. Georgia is a member of the United Nations, the Council of Europe, and it contains two de facto independent regions, Abkhazia and South Ossetia, which gained limited international recognition after the 2008 Russo-Georgian War. Georgia and a part of the international community consider the regions to be part of Georgias sovereign territory under Russian military occupation. Georgia probably stems from the Persian designation of the Georgians – gurğān, in the 11th and 12th centuries adapted via Syriac gurz-ān/gurz-iyān, starting with the Persian word gurğ/gurğān, the word was later adopted in numerous other languages, including Slavic and West European languages. This term itself might have established through the ancient Iranian appellation of the near-Caspian region. The self-designation used by ethnic Georgians is Kartvelebi, the medieval Georgian Chronicles present an eponymous ancestor of the Kartvelians, Kartlos, a great-grandson of Japheth. However, scholars agree that the word is derived from the Karts, the name Sakartvelo consists of two parts. Its root, kartvel-i, specifies an inhabitant of the core central-eastern Georgian region of Kartli, ancient Greeks and Romans referred to early western Georgians as Colchians and eastern Georgians as Iberians. Today the full, official name of the country is Georgia, before the 1995 constitution came into force the countrys name was the Republic of Georgia. The territory of modern-day Georgia was inhabited by Homo erectus since the Paleolithic Era, the proto-Georgian tribes first appear in written history in the 12th century BC. The earliest evidence of wine to date has found in Georgia. In fact, early metallurgy started in Georgia during the 6th millennium BC, the classical period saw the rise of a number of early Georgian states, the principal of which was Colchis in the west and Iberia in the east

South Ossetia
–
It has a population of 53,000 people which live in an area of 3,900 km2, south of the Russian Caucasus, with 30,000 living in its capital city of Tskhinvali. South Ossetia declared independence from the Georgian Soviet Socialist Republic in 1991, the Georgian government responded by abolishing South Ossetias autonomy and trying to re-establish its control over the region by force. The crisis escalation led to the 1991–92 South Ossetia War, Georgian fighting against those controlling South Ossetia occurred on two other occasions, in 2004 and 2008. The latter conflict led to the Russo–Georgian War, during which Ossetian and Russian forces gained full de facto control of the territory of the former South Ossetian Autonomous Oblast. In the wake of the 2008 war, Russia, followed by Nicaragua, Venezuela, Georgia and a significant part of the international community consider South Ossetia to be occupied by the Russian military. South Ossetia relies heavily on military, political and financial aid from Russia, Russia does not allow European Union Monitoring Mission monitors to enter South Ossetia. South Ossetia, Transnistria, Nagorno-Karabakh, and Abkhazia are sometimes referred to as post-Soviet frozen conflict zones, the Ossetians are believed to originate from the Alans, a Sarmatian Iranian tribe. In the 17th century, Ossetians started migration from the North Caucasus to Georgia, Ossetian peasants, who were migrating to the mountainous areas of the South Caucasus, often settled in the lands of Georgian feudal lords. The Georgian King of the Kingdom of Kartli permitted Ossetians to immigrate, in the 1770s there were more Ossetians living in Kartli than ever before. This period has been documented in the diaries of Johann Anton Güldenstädt who visited Georgia in 1772. The Baltic German explorer called modern North Ossetia simply Ossetia, while he wrote that Kartli was populated by Georgians, Güldenstädt also wrote that the northernmost border of Kartli is the Major Caucasus Ridge. The Georgian Kingdom of Kartli-Kakheti, part of which was the territory of modern South Ossetia, was annexed by the Russian Empire in 1801. Following the Russian revolution, the area of modern South Ossetia became part of the Democratic Republic of Georgia, although the Ossetians were initially discontented with the economic policies of the central government, the tension soon transformed into ethnic conflict. The first Ossetian rebellion began in February 1918, when three Georgian princes were killed and their land was seized by the Ossetians, the central government of Tiflis retaliated by sending the National Guard to the area. However, the Georgian unit retreated after they had engaged the Ossetians, Ossetian rebels then proceeded to occupy the town of Tskhinvali and began attacking ethnic Georgian civilian population. During uprisings in 1919 and 1920, the Ossetians were covertly supported by Soviet Russia, but even so, were defeated. Between 3,000 and 7,000 Ossetians were killed during the crushing of the 1920 uprising, according to Ossetian sources ensuing hunger, the drawing of administrative boundaries of the South Ossetian AO was quite a complicated process. Many Georgian villages were included within the South Ossetian AO despite numerous protests by the Georgian population, while the city of Tskhinvali did not have a majority Ossetian population, it was made the capital of the South Ossetian AO

Central bank
–
A central bank, reserve bank, or monetary authority is an institution that manages a states currency, money supply, and interest rates. Central banks also usually oversee the commercial banking system of their respective countries, Central banks in most developed nations are institutionally designed to be independent from political interference. Still, limited control by the executive and legislative bodies usually exists, prior to the 17th century most money was commodity money, typically gold or silver. However, promises to pay were widely circulated and accepted as value at least five hundred years earlier in both Europe and Asia. The Song dynasty was the first to issue generally circulating paper currency, in 1455, in an effort to control inflation, the succeeding Ming Dynasty ended the use of paper money and closed much of Chinese trade. The Bank of Amsterdam, established in the Dutch Republic in 1609, is considered to be the forerunner to modern central banks. The Wisselbanks innovations helped lay the foundations for the birth and development of the banking system that now plays a vital role in the worlds economy. Along with a number of local banks, it performed many functions of a central banking system. Lucien Gillard calls it the European guilder, and Adam Smith devotes many pages to explaining how the bank guilder works, the model of the Wisselbank as a state bank was adapted throughout Europe, including the Bank of Sweden and the Bank of England. Established by Dutch-Latvian Johan Palmstruch in 1668, Sveriges Riksbank is often considered by many as the worlds oldest central bank, the lenders would give the government cash and also issue notes against the government bonds, which could be lent again. A Royal Charter was granted on 27 July through the passage of the Tonnage Act 1694, the bank was given exclusive possession of the governments balances, and was the only limited-liability corporation allowed to issue banknotes. The £1. 2M was raised in 12 days, half of this was used to rebuild the Navy and these modern central banking functions evolved slowly through the 18th and 19th centuries. The currency crisis of 1797, caused by panicked depositors withdrawing from the Bank led to the government suspending convertibility of notes into specie payment. The bank was accused by the bullionists of causing the exchange rate to fall from over issuing banknotes. Nevertheless, it was clear that the Bank was being treated as an organ of the state, henry Thornton, a merchant banker and monetary theorist has been described as the father of the modern central bank. An opponent of the real bills doctrine, he was a defender of the bullionist position, thorntons process of monetary expansion anticipated the theories of Knut Wicksell regarding the cumulative process which restates the Quantity Theory in a theoretically coherent form. Until the mid-nineteenth century, commercial banks were able to issue their own banknotes, many consider the origins of the central bank to lie with the passage of the Bank Charter Act of 1844. Under this law, authorisation to issue new banknotes was restricted to the Bank of England, at the same time, the Bank of England was restricted to issue new banknotes only if they were 100% backed by gold or up to £14 million in government debt

Colchis
–
Colchis was an ancient kingdom and region on the coast of the Black Sea, centered in present-day western Georgia. Internationally, Colchis is perhaps best known for its role in Greek mythology, most notably as the destination of the Argonauts, as well as the home to Medea and the Golden fleece. Colchis was populated by Colchians, an early Kartvelian-speaking tribe, ancestral to the contemporary Western Georgians, namely Svans and Mingrelians, the kingdom of Colchis, Kolkhis or Qulha which existed from the c. According to the scholar of Caucasian studies Cyril Toumanoff, Colchis appears as the first Caucasian State to have achieved the coalescence of the newcomer. Colchis can be regarded as not a proto-Georgian, but a Georgian kingdom. It would seem natural to seek the beginnings of Georgian social history in Colchis. A second South Caucasian tribal union emerged in the 13th century BC on the Black Sea coast. There is some difference in authors as to the extent of the country westward, thus Strabo makes Colchis begin at Trabzon, while Ptolemy, on the other hand. The name of Colchis first appears in Aeschylus and Pindar, the earlier writers only speak about it under the name of Aea, the residence of the mythical king Aeëtes, Kolchian Aia lies at the furthest limits of sea and earth, wrote Apollonius of Rhodes. Scylax mentions also Mala or Male, which he, in contradiction to other writers, the central part of the region is Colchis Plain, stretching between Sokhumi and Kobuleti, most of that lies on the elevation below 20 m above sea level. Marginal parts of the region are mountains of the Great and the Lesser Caucasus, the climate is mild humid, near Batumi, annual rainfall level reaches 4,000 mm, which is the absolute maximum for the continental western Eurasia. The dominating natural landscapes of Colchis are temperate rainforests, yet degraded in the part of the region, wetlands. In at least some parts of Colchis, the process of urbanization seems to have been advanced by the end of the 2nd millennium BC. The Colchian Late Bronze Age saw the development of significant skill in the smelting and casting of metals, sophisticated farming implements were made, and fertile, well-watered lowlands and a mild climate promoted the growth of progressive agricultural techniques. Colchis was inhabited by a number of related but distinct tribes whose settlements lay along the shore of the Black Sea and these Colchian tribes differed so completely in language and appearance from the surrounding Indo-European nations that the ancients provided various wild theories to account for the phenomenon. Herodotus regarded the Colchians as Ancient Egyptian race, Apollonius of Rhodes states that the Egyptians of Colchis preserved as heirlooms a number of wooden tablets, which show, with considerable accuracy, seas and highways. Detlev Fehling regards the link between Colchis and Egypt as a clear example of the way Herodotus used spurious sources to back up stories he had made up himself. In the 13th century BC, the Kingdom of Colchis was formed as a result of the consolidation of the tribes inhabiting the region. This power, celebrated in Greek mythology as the destination of the Argonauts, the home of Medea, the kingdom of Tabal was conquered by the Assyrian emperor Shalmaneser III in the 830s BC

Georgian scripts
–
The Georgian scripts are the three writing systems used to write the Georgian language, Asomtavruli, Nuskhuri and Mkhedruli. Although the systems differ in appearance, all three are unicase, their letters share the names and alphabetical order, and are written horizontally from left to right. Of the three scripts, Mkhedruli was the civilian royal script of the Kingdom of Georgia mostly used for the royal charters, originally consisting of 38 letters, Georgian is presently written in a 33-letter alphabet, as five letters are currently obsolete in that language. The number of Georgian letters used in other Kartvelian languages varies, the Mingrelian language uses 36,33 of which are current Georgian letters, one obsolete Georgian letter, and two additional letters specific to Mingrelian and Svan. That same obsolete letter, plus a letter borrowed from Greek, are used in writing the Laz language, Georgian scripts were granted the national status of cultural heritage in Georgia in 2015 and inscribed on the UNESCO Representative List of the Intangible Cultural Heritage of Humanity in 2016. The first version of the script attested is Asomtavruli which dates back to at least the 5th century, most scholars link the creation of the Georgian script to the process of Christianization of Iberia, a core Georgian kingdom of Kartli. The alphabet was therefore most probably created between the conversion of Iberia under King Mirian III and the Bir el Qutt inscriptions of 430 and it was first used for translation of the Bible and other Christian literature into Georgian, by monks in Georgia and Palestine. This account is now considered legendary, and is rejected by scholarly consensus, a point of contention among scholars is the role played by Armenian clerics in that process. Other scholars quote Koryuns claims without taking a stance on its validity, many agree, however, that Armenian clerics, if not Mashtots himself, must have played a role in the creation of the Georgian script. Another controversy regards the main influences at play in the Georgian alphabet, as scholars have debated whether it was inspired more by the Greek alphabet, or by Semitic alphabets such as Aramaic. Recent historiography focuses on greater similarities with the Greek alphabet than in the other Caucasian writing systems, most notably the order, some scholars have also suggested as a possible inspiration for particular letters certain pre-Christian Georgian cultural symbols or clan markers. Asomtavruli is the oldest Georgian script, the name Asomtavruli means capital letters, from aso letter and mtavari principal/head. It is also known as Mrgvlovani rounded, from mrgvali round, despite its name, this capital script is unicameral, just like the modern Georgian script, Mkhedruli. The oldest Asomtavruli inscriptions found so far date from the 5th century and are Bir el Qutt, from the 9th century, Nuskhuri script starting becoming dominant, and the role of Asomtavruli was reduced. However, epigraphic monuments of the 10th to 18th centuries continued to be written in Asomtavruli script, Asomtavruli in this later period became more decorative. In the majority of 9th-century Georgian manuscripts which were written in Nuskhuri script, Asomtavruli was used for titles, although, some manuscripts written completely in Asomtavruli can be found until the 11th century. In early Asomtavruli, the letters are of equal height, in most Asomtavruli letters, straight lines are horizontal or vertical and meet at right angles. The only letter with acute angles is Ⴟ, there have been various attempts to explain this exception

Stainless steel
–
In metallurgy, stainless steel, also known as inox steel or inox from French inoxydable, is a steel alloy with a minimum of 10. 5% chromium content by mass. Stainless steel is notable for its resistance, and it is widely used for food handling. Stainless steel does not readily corrode, rust or stain with water as ordinary steel does, however, it is not fully stain-proof in low-oxygen, high-salinity, or poor air-circulation environments. There are various grades and surface finishes of stainless steel to suit the environment the alloy must endure, Stainless steel is used where both the properties of steel and corrosion resistance are required. Stainless steel differs from carbon steel by the amount of chromium present, unprotected carbon steel rusts readily when exposed to air and moisture. This iron oxide film is active and accelerates corrosion by making it easier for more iron oxide to form, since iron oxide has lower density than steel, the film expands and tends to flake and fall away. In comparison, stainless steels contain sufficient chromium to undergo passivation and this layer prevents further corrosion by blocking oxygen diffusion to the steel surface and stops corrosion from spreading into the bulk of the metal. Passivation occurs only if the proportion of chromium is high enough, Stainless steel’s resistance to corrosion and staining, low maintenance, and familiar lustre make it an ideal material for many applications. Storage tanks and tankers used to transport orange juice and other food are made of stainless steel. This also influences its use in kitchens and food processing plants, as it can be steam-cleaned and sterilized. High oxidation resistance in air at ambient temperature is achieved with addition of a minimum of 13% chromium. The chromium forms a layer of chromium oxide when exposed to oxygen. The layer is too thin to be visible, and the metal remains lustrous, the layer is impervious to water and air, protecting the metal beneath, and this layer quickly reforms when the surface is scratched. This phenomenon is called passivation and is seen in other metals, corrosion resistance can be adversely affected if the component is used in a non-oxygenated environment, a typical example being underwater keel bolts buried in timber. When stainless steel parts such as nuts and bolts are forced together, when forcibly disassembled, the welded material may be torn and pitted, a destructive effect known as galling. Galling can be avoided by the use of materials for the parts forced together, for example bronze and stainless steel. However, two different alloys electrically connected in a humid, even mildly acidic environment may act as a voltaic pile, nitronic alloys, made by selective alloying with manganese and nitrogen, may have a reduced tendency to gall. Additionally, threaded joints may be lubricated to provide a film between the two parts and prevent galling, low-temperature carburizing is another option that virtually eliminates galling and allows the use of similar materials without the risk of corrosion and the need for lubrication

Borjgali
–
Borjgali is a Georgian symbol of the Sun with seven rotating wings over the Christian Tree of Life and is related to the Mesopotamian symbols of eternity. It is also related to the Triskelion, another symbol of eternity. It is usually depicted within the circle symbolizes the Universe. The roots of the Tree go into the past and its branches are for the future. The Tree itself symbolizes the continuity between past, present and the future, the Borjgali is usually placed above the tree and symbolizes the Sun, eternal movement and life. The term Borjgali is believed to derive from Megrelian word ბარჩხალი, some other scholars believe that it has different origins. In old Megrelian borj means time and gal means pass or flow, so the whole phrase would mean the flow of time. Nowadays, the symbol is used in Georgian IDs and passports, as well as on currency, Georgian rugby team players are called ბორჯღალოსნები, which means Men bearing Borjgali

Sun
–
The Sun is the star at the center of the Solar System. It is a perfect sphere of hot plasma, with internal convective motion that generates a magnetic field via a dynamo process. It is by far the most important source of energy for life on Earth. Its diameter is about 109 times that of Earth, and its mass is about 330,000 times that of Earth, accounting for about 99. 86% of the total mass of the Solar System. About three quarters of the Suns mass consists of hydrogen, the rest is mostly helium, with smaller quantities of heavier elements, including oxygen, carbon, neon. The Sun is a G-type main-sequence star based on its spectral class and it formed approximately 4.6 billion years ago from the gravitational collapse of matter within a region of a large molecular cloud. Most of this matter gathered in the center, whereas the rest flattened into a disk that became the Solar System. The central mass became so hot and dense that it eventually initiated nuclear fusion in its core and it is thought that almost all stars form by this process. The Sun is roughly middle-aged, it has not changed dramatically for more than four billion years and it is calculated that the Sun will become sufficiently large enough to engulf the current orbits of Mercury, Venus, and probably Earth. The enormous effect of the Sun on Earth has been recognized since prehistoric times, the synodic rotation of Earth and its orbit around the Sun are the basis of the solar calendar, which is the predominant calendar in use today. The English proper name Sun developed from Old English sunne and may be related to south, all Germanic terms for the Sun stem from Proto-Germanic *sunnōn. The English weekday name Sunday stems from Old English and is ultimately a result of a Germanic interpretation of Latin dies solis, the Latin name for the Sun, Sol, is not common in general English language use, the adjectival form is the related word solar. The term sol is used by planetary astronomers to refer to the duration of a solar day on another planet. A mean Earth solar day is approximately 24 hours, whereas a mean Martian sol is 24 hours,39 minutes, and 35.244 seconds. From at least the 4th Dynasty of Ancient Egypt, the Sun was worshipped as the god Ra, portrayed as a falcon-headed divinity surmounted by the solar disk, and surrounded by a serpent. In the New Empire period, the Sun became identified with the dung beetle, in the form of the Sun disc Aten, the Sun had a brief resurgence during the Amarna Period when it again became the preeminent, if not only, divinity for the Pharaoh Akhenaton. The Sun is viewed as a goddess in Germanic paganism, Sól/Sunna, in ancient Roman culture, Sunday was the day of the Sun god. It was adopted as the Sabbath day by Christians who did not have a Jewish background, the symbol of light was a pagan device adopted by Christians, and perhaps the most important one that did not come from Jewish traditions

Tree of life
–
The concept of a tree of life is a widespread mytheme or archetype in the worlds mythologies, related to the concept of sacred tree more generally, and hence in religious and philosophical tradition. The expression Tree of Life was used as a metaphor for the tree of common descent in the evolutionary sense in a famous passage by Charles Darwin. Various trees of life are recounted in folklore, culture and fiction and they had their origin in religious symbolism. The Eternal Banyan Tree is located on the bank of the Yamuna inside the courtyard of Allahabad Fort near the confluence of the Yamuna, the eternal and divine nature of this tree has been documented at length in the scriptures. During the cyclic destruction of creation when the earth was enveloped by waters. It is on the leaves of tree that Lord Krishna rested in the form of a baby when land was no longer visible. And it is here that the sage, Markandeya, received the cosmic vision of the Lord. It is under this tree that Buddha meditates eternally, legend also has it that the Bodi tree at Gaya is a manifestation of this tree. In pre-Islamic Persian mythology, the Gaokerena world tree is a large, ahriman created a frog to invade the tree and destroy it, aiming to prevent all trees from growing on the earth. As a reaction, God created two kar fish staring at the frog to guard the tree, the two fishes are always staring at the frog and stay ready to react to it. The sacred plant haoma and the drink made from it, the preparation of the drink from the plant by pounding and the drinking of it are central features of Zoroastrian ritual. Haoma is also personified as a divinity and it bestows essential vital qualities—health, fertility, husbands for maidens, even immortality. The source of the haoma plant is a shining white tree that grows on a paradisiacal mountain. Sprigs of this white haoma were brought to earth by divine birds, Haoma is the Avestan form of the Sanskrit soma. The near identity of the two in ritual significance is considered by scholars to point to a salient feature of an Indo-Iranian religion antedating Zoroastrianism. Another related issue in ancient mythology of Iran is the myth of Mashyа and Mashyane and this myth can be considered as a prototype for the creation myth where living beings are created by Gods. To the Ancient Egyptians, the Tree of Life represented the hierarchical chain of events that brought everything into existence, the spheres of the Tree of Life demonstrate the order, process, and method of creation. In Egyptian mythology, in the Ennead system of Heliopolis, the first couple, apart from Shu and Tefnut and Geb and Nut, are Isis and Osiris

Vine
–
A vine in the narrowest sense is the grapevine, but more generally it can refer to any plant with a growth habit of trailing or scandent stems, lianas or runners. The word also can refer to such stems or runners themselves, in the United Kingdom, the term vine applies almost exclusively to the grapevine. The term climber is used for all climbing plants, certain plants always grow as vines, while a few grow as vines only part of the time. For instance, poison ivy and bittersweet can grow as low shrubs when support is not available, a vine displays a growth form based on long stems. This has been a successful growth form for plants such as kudzu and Japanese honeysuckle. There are some tropical vines that develop skototropism, and grow away from the light, growth away from light allows the vine to reach a tree trunk, which it can then climb to brighter regions. The vine growth form may also enable plants to large areas quickly. This is the case with periwinkle and ground ivy and it is also an adaptation to life in areas where small patches of fertile soil are adjacent to exposed areas with more sunlight but little or no soil. A vine can root in the soil but have most of its leaves in the brighter, exposed area, the evolution of a climbing habit has been implicated as a key innovation associated with the evolutionary success and diversification of a number of taxonomic groups of plants. It has evolved independently in several plant families, using many different climbing methods such as and it directs its stem into a crevice in the bark of fibrous barked trees where the stem adopts a flattened profile and grows up the tree underneath the host trees outer bark. The fetterbush then sends out branches that emerge near the top of the tree and these may be divided into woody vines or lianas, such as wisteria, kiwifruit, and common ivy, and herbaceous vines, such as morning glory. One odd group of vining plants is the fern genus Lygodium, the stem does not climb, but rather the fronds do. The fronds unroll from the tip, and theoretically never stop growing, they can form thickets as they unroll over other plants, rockfaces, gardeners can use the tendency of climbing plants to grow quickly. If a plant display is wanted quickly, a climber can achieve this, climbers can be trained over walls, pergolas, fences, etc. Climbers can be grown over other plants to provide additional attraction, artificial support can also be provided. Some climbers climb by themselves, others need work, such as tying them in, vines widely differ in size, form and evolutionary origin. Darwin classified climbing groups based on their climbing method and he classified five classes of vines including twining plants, leaf climbers, tendril bearers, root climbers and hook climbers. Vines are unique in that they have multiple origins and a wide range of phenotypic plasticity

Peafowl
–
The peafowl include three species of birds in the genera Pavo and Afropavo of the Phasianidae family, the pheasants and their allies. There are two Asiatic species and one African species, male peafowl are known for their piercing call and their extravagant plumage. The latter is especially prominent in the Asiatic species, who have a tail or train of covert feathers which they display as part of a courtship ritual. The term peacock is properly reserved for the male, the female is known as a peahen, the functions of the elaborate iridescent coloration and large train of peacocks have been the subject of extensive scientific debate. Charles Darwin suggested they served to attract females, and the features of the males had evolved by sexual selection. The Indian peacock has iridescent blue and green plumage, the peacock tail, known as a train, consists not of tail quill feathers, but highly elongated upper tail coverts. These feathers are marked with eyespots, best seen when a peacock fans his tail, both sexes of all species have a crest atop the head. The Indian peahen has a mixture of grey, brown. The female also displays her plumage to ward off female competition or signal danger to her young, the green peafowl differs from the Indian peafowl in that the male has green and gold plumage with black wings with a sheen of blue. Unlike the Indian peafowl, the green peahen is similar to the male, only having shorter upper tail coverts, a more coppery neck, the Congo peacock male does not display his covert feathers, but uses his actual tail feathers during courtship displays. These feathers are shorter than those of the Indian and green species. Females of the Indian and African species are dull grey and/or brown, chicks of both sexes in all the species are cryptically coloured. They vary between yellow and tawny, usually with patches of brown or light tan and dirty white ivory. Occasionally, peafowl appear with white plumage and this can result in the complete lack of coloration of their plumage, while preserving normal eye colour. By contrast, true albino peafowl have a lack of melanin. Leucistic peachicks are born yellow and become white as they mature. As with many birds, vibrant iridescent plumage colours are not primarily pigments, optical interference Bragg reflections based on regular, periodic nanostructures of the barbules of the feathers produce the peacocks colours. Slight changes to the spacing of these result in different colours
