63-420: A flag day is a flag -related holiday, a day designated for flying a certain flag (such as a national flag ) or a day set aside to celebrate a historical event such as a nation's adoption of its flag. Flag days are usually codified in national statutes passed by legislative bodies or parliaments ; however, in some countries a decree or proclamation by the head of state or chief executive can also order
126-625: A heraldic device in battle, allowing easier identification of a knight over only the heraldic icon painted on the shield. Already during the high medieval period, and increasingly during the Late Middle Ages , city states and communes such as those of the Old Swiss Confederacy also began to use flags as field signs. Regimental flags for individual units became commonplace during the Early Modern period . During

In Ireland, a red and yellow flag indicates that it is safe to swim; a red flag that it is unsafe; and no flag indicates that there are no lifeguards on duty. Blue flags may also be used away from the yellow-red lifesaver area to designate
252-410: A flag day. The statute, or the proclamation or decree, may specify locations where flags are to be flown and how (for example, at full- or half-staff ); alternatively, custom may prevail. The flag day is naturally a flag flying day . Nations that are not broadly recognized sovereign states are shown in pink . Defunct states are highlighted in light grey . Saudi Flag Day Flag A flag

In times of war waving a white flag is a banner of truce, talks/negotiations or surrender. Four distinctive African flags currently in the collection of the National Maritime Museum in Britain were flown in action by Itsekiri ships under
441-495: A military or naval context began with the rise of nationalism by the end of the 18th century, although some flags date back earlier. The flags of countries such as Austria, Denmark or Turkey have legendary origins while many others, including those of Poland and Switzerland, grew out of the heraldic emblems of the Middle Ages. The 17th century saw the birth of several national flags through revolutionary struggle. One of these
504-1094: A mixture of both taurine and zebu types of cattle ( B. p. taurus and B. p. indicus ) with yak. According to the International Veterinary Information Service , the low productivity of second-generation cattle–yak crosses makes them suitable only as meat animals. Crosses between yaks and domestic cattle ( Bos primigenius taurus ) have been recorded in Chinese literature for at least 2,000 years. Successful crosses have also been recorded between yak and American bison , gaur , and banteng , generally with similar results to those produced with domestic cattle. Jacques et al. (2021) show that most elaborate yak-related terminologies are found within Tibetic and Gyalrongic languages. Both branches also have native terms for yak-cattle hybrids , suggesting that Tibetic and Gyalrongic speakers may have independently cross-bred yaks and cattle, predating

The de jure flag of Libya under Muammar Gaddafi , which consisted of a rectangular field of green, was for a long period the only national flag using a single colour and no design or insignia. However, other historical states have also used flags without designs or insignia, such as the short-lived Soviet Republic of Hungary and
1071-616: Is equivalent to a brigade in Arab countries. In Spain, a flag (Spanish: bandera ) is a battalion -equivalent in the Spanish Legion . The origin of the flag is unknown and it remains unclear when the first flag was raised. Ships with vexilloids were represented on predynastic Egyptian pottery c. 3500 BC . In antiquity, field signs that can be categorised as vexilloid or "flag-like" were used in warfare, originating in ancient Egypt or Assyria . Examples include

1197-687: Is likely that this may be somewhat shorter in the wild. For thousands of years, domesticated yaks have been kept in Mongolia and Tibet, primarily for their milk, fibre (wool), and meat, and as beasts of burden . Their dried droppings are an important fuel, used all over Tibet, and are often the only fuel available on the high, treeless Tibetan Plateau . Yaks transport goods across mountain passes for local farmers and traders and are an attraction for climbing and trekking expeditions: "Only one thing makes it hard to use yaks for long journeys in barren regions. They will not eat grain , which could be carried on

In Nepal , Tibet , and Mongolia , domestic cattle are crossbred with yaks. This gives rise to the infertile male dzo མཛོ། as well as fertile females known as dzomo or zhom མཛོ་མོ།, which may be crossed again with cattle. The Dwarf Lulu breed, "the only Bos primigenius taurus type of cattle in Nepal" has been tested for DNA markers and found to be

#17327768934961386-401: Is used to mark the limits of the bathing area on a beach, usually guarded by surf lifesavers . If the beach is closed, the poles of the flags are crossed. The flags are coloured with a red triangle and a yellow triangle making a rectangular flag, or a red rectangle over a yellow rectangle. On many Australian beaches there is a slight variation with beach condition signalling. A red flag signifies
1449-604: Is used). Many flags fall into groups of similar designs called flag families . The study of flags is known as " vexillology " from the Latin vexillum , meaning "flag" or " banner ". National flags are patriotic symbols with widely varied interpretations that often include strong military associations because of their original and ongoing use for that purpose. Flags are also used in messaging , advertising , or for decorative purposes. Some military units are called "flags" after their use of flags. A flag (Arabic: لواء )
1512-439: The 5 October 1910 revolution which brought this party to power. Throughout history, monarchs have often had personal flags (including royal standards ), representing the royal person, including in personal union of national monarchies. Flags are often representative of an individual's affinity or allegiance to a country, team or business and can be presented in various ways. A popular trend that has surfaced revolves around
1575-577: The Indian subcontinent or the Zhou dynasty of Ancient China . Chinese flags had iconography such as a red bird, a white tiger, or a blue dragon, and royal flags were to be treated with a level of respect similar to that given to the ruler. Indian flags were often triangular and decorated with attachments such as a yak 's tail and the state umbrella. Silk flags either spread to the Near East from China or it

While the origin of the flag remains
1764-568: The cross , the crescent , or a reference to a patron saint. Flags are also adopted by religious groups and flags such as the Jain flag , Nishan Sahib ( Sikhism ), the Saffron flag ( Hindu ) and the Christian flag are used to represent a whole religion. Because of their ease of signalling and identification, flags are often used in sports . Some countries use diplomatic flags, such as
1827-583: The national flag . Other countries' armed forces (such as those of the United States or Switzerland) use their standard national flag ; in addition, the U.S. has alongside flags and seals designed from long tradition for each of its six uniformed military services/military sub-departments in the Department of Defense and the Department of Homeland Security . The Philippines' armed forces may use their standard national flag , but during times of war
1890-674: The rainbow flag was adopted as a symbol of the LGBT social movements . Its derivatives include the Bisexual pride and Transgender pride flags . Some of these political flags have become national flags, such as the red flag of the Soviet Union and national socialist banners for Nazi Germany . The present Flag of Portugal is based on what had been the political flag of the Portuguese Republican Party previous to
1953-652: The United Kingdom (see image of the Embassy flag ) and the Kingdom of Thailand (see image of the Embassy flag ). The socialist movement uses red flags to represent their cause. The anarchist movement has a variety of different flags, but the primary flag associated with them is the black flag . In the Spanish Civil War , the anarchists used the red-and-black bisected flag. In the 20th century,

2016-587: The United States, Canada, New Zealand, and some parts of Europe. Yaks have generated interest outside the Himalayas as a commercial crop and by cattle breeders. The main interest of North American yak breeders is lean meat production by hybridizing with other cattle, followed by wool production. The Indian government established a dedicated centre for research into yak husbandry, the ICAR-National Research Centre on Yak, in 1989. It
2079-490: The alphabet. Each flag or pennant has a specific meaning when flown individually. As well, semaphore flags can be used to communicate on an ad hoc basis from ship to ship over short distances. Another category of maritime flag flown by some United States government ships is the distinctive mark . Although the United States Coast Guard has its own service ensign, all other U.S. government ships fly
2142-523: The belly. While wild yaks are generally dark, blackish to brown in colouration, domestic yaks can be quite variable, often having rusty brown and cream patches. They have small ears and broad foreheads, with smooth horns that are generally dark in colour. In males (bulls), the horns sweep out from the sides of the head and then curve backwards; they typically range from 48 to 99 cm (19 to 39 in) in length. The horns of females (cows) are smaller, at 27 to 64 cm (11 to 25 in) in length, and have
2205-606: The cold include a thick layer of subcutaneous fat and an almost complete lack of functional sweat glands . Compared with domestic cattle, the rumen of yaks is unusually large, relative to the omasum . This likely allows them to consume greater quantities of low-quality food at a time, and to ferment it longer to extract more nutrients. Yak consume the equivalent of 1% of their body weight daily while cattle require 3% to maintain condition. They are grazing herbivores, with their wild ancestors feeding primarily on grass and sedges , with some herbs and dwarf shrubs. Yaks mate in

A civil flag is a version of the national flag that is flown by civilians on non-government installations or craft. The use of civil flags was more common in the past, in order to denote buildings or ships that were not crewed by
2394-621: The domestic yak variant, Bos grunniens (grunting bull). Nikolay Przhevalsky named the wild variant Bos mutus (silent bull), believing that it did not make a sound at all, but it does. Yak physiology is well adapted to high altitudes , having larger lungs and heart than cattle found at lower altitudes, as well as greater capacity for transporting oxygen through their blood, due to the persistence of foetal haemoglobin throughout life. Conversely, yaks have trouble thriving at lower altitudes, and are prone to suffering from heat exhaustion above about 15 °C (59 °F). Further adaptations to

As of 2009 , this custom is still taken seriously by many naval and port authorities and is readily enforced in many parts of the world by boarding, confiscation and other civil penalties. In some countries yacht ensigns are different from merchant ensigns in order to signal that
2520-400: The flag is turned upside down. Bulgaria's flag is also turned upside down during times of war. These are also considered war flags, though the terminology only applies to the flag's military usage. Large versions of the war flag flown on the warships of countries' navies are known as battle ensigns . In addition, besides flying the national standard or a military services' emblem flag at
2583-423: The genus Bos , Yaks are related to cattle ( Bos primigenius ). Mitochondrial DNA analyses to determine the evolutionary history of yaks have been inconclusive. The yak may have diverged from cattle at any point between one and five million years ago, and there is some suggestion that it may be more closely related to bison than to the other members of its designated genus. Apparent close fossil relatives of

Yaks' milk is often processed to a cheese called chhurpi in Tibetan and Nepali languages, and byaslag in Mongolia. Butter made from yaks' milk is an ingredient of the butter tea that Tibetans consume in large quantities, and is also used in lamps and made into butter sculptures used in religious festivities. Small numbers of herds can be found in

Colours are normally described with common names, such as "red", but may be further specified using colourimetry . The largest flag flown from a flagpole worldwide, according to Guinness World Records, is the flag of the United Arab Emirates flown in Sharjah . This flag was 2,448.56 m (26,356.1 sq ft). The largest flag ever made
2961-610: The national ensign as their service ensign, following United States Navy practice. To distinguish themselves from ships of the Navy, such ships historically have flown their parent organisation's flag from a forward mast as a distinctive mark. Today, for example, commissioned ships of the National Oceanic and Atmospheric Administration (NOAA) fly the NOAA flag as a distinctive mark. Flags are usually rectangular in shape (often in
3024-584: The pair soon rejoin the herd. Females of both the wild and domestic forms typically give birth only once every other year, although more frequent births are possible if the food supply is good. Calves are weaned at one year and become independent shortly thereafter. Wild calves are initially brown in color and only later develop darker adult hair. Females generally give birth for the first time at three or four years of age, and reach their peak reproductive fitness at around six years. Yaks may live for more than twenty years in domestication or captivity, although it
3087-437: The peak of the sailing age , beginning in the early 17th century, it was customary (and later a legal requirement) for ships to fly flags designating their nationality; these flags eventually evolved into the national flags and maritime flags of today. Flags also became the preferred means of communications at sea, resulting in various systems of flag signals; see, International maritime signal flags . Use of flags beyond
3150-588: The preferred name for the wild species. Although some authors still consider the wild yak to be a subspecies , Bos grunniens mutus , the ICZN made an official ruling in 2003 permitting the use of the name Bos mutus for wild yaks , and this is now the more common usage. There are no recognised subspecies of yak except where the wild yak is considered a subspecies of Bos grunniens . Yaks are heavily built animals with bulky frames, sturdy legs, rounded, cloven hooves, and extremely dense, long fur hanging lower than
3213-652: The proto-Gyalrongic split (3221 [2169–4319] BP ) from Tibeto-Gyalrongic. The oldest dated physical evidence of yak domestication is from 2,500 years BP. In parts of Tibet and Karakorum, yak racing is a form of entertainment at traditional festivals and an important part of their culture. More recently, sports involving domesticated yaks, such as yak skiing or yak polo , are being marketed as tourist attractions in South Asian countries, including in Gilgit-Baltistan , Pakistan.

A more unusual flag shape is that of the flag of Nepal , which is in the shape of two stacked triangles. Other unusually shaped flags include the civil flags of Ohio (a swallowtail ); Tampa, Florida ; and Pike County, Ohio . Many flags are dyed through and through to be inexpensive to manufacture, such that
3339-415: The reverse side is the mirror image of the obverse (front) side, generally the side displayed when, from the observer's point of view, the flag flies from pole-side left to right. This presents two possibilities: Some complex flag designs are not intended to be shown on both sides, requiring separate obverse and reverse sides if made correctly. In these cases there is a design element (usually text) which
3402-412: The rules and regulations for the flying of flags are strictly enforced. A national flag flown at sea is known as an ensign . A courteous, peaceable merchant ship or yacht customarily flies its ensign (in the usual ensign position), together with the flag of whatever nation it is currently visiting at the mast (known as a courtesy flag ). To fly one's ensign alone in foreign waters, a foreign port or in
3465-414: The rut, often while scent-marking with urine or dung. Females enter oestrus up to four times a year, and females are receptive only for a few hours in each cycle. Gestation lasts between 257 and 270 days, so that the young are born between May and June, and results in the birth of a single calf. The cow finds a secluded spot to give birth, but the calf can walk within about ten minutes of birth, and
3528-514: The standard horizontal flag in central and eastern Europe, particularly in the German-speaking countries. This practice came about because the relatively brisk wind needed to display horizontal flags is not common in these countries. The standard horizontal flag (no. 1 in the preceding illustration) is nonetheless the form most often used even in these countries. The vertical flag (German: Hochformatflagge or Knatterflagge ; no. 2)
3591-579: The summer, typically between July and September, depending on the local environment. For the remainder of the year, many bulls wander in small bachelor groups away from the large herds. Still, as the rut approaches, they become aggressive and regularly fight with each other to establish dominance. In addition to non-violent threat displays, bellowing, and scraping the ground with their horns, bull yaks compete more directly, repeatedly charging at each other with heads lowered or sparring with their horns. Like bison , but unlike cattle, males wallow in dry soil during

Traditionally, a vessel flying under the courtesy flag of a specific nation, regardless of the vessel's country of registry, is considered to be operating under the law of her 'host' nation. There is a system of international maritime signal flags for numerals and letters of
3780-481: The yak, such as Bos baikalensis , have been found in eastern Russia, suggesting a possible route by which yak-like ancestors of the modern American bison could have entered the Americas. The species was originally designated as Bos grunniens ("grunting ox") by Linnaeus in 1766. Still, this name is now generally considered to refer only to the domesticated form of the animal, with Bos mutus ("mute ox") being
