Deer are the ruminant mammals forming the family Cervidae. They include for example Moose, Red Deer, Reindeer, Roe and Chital. Animals from related families within the order Artiodactyla (even-toed ungulates) are often also considered to be deer – these include muntjac and water deer. Male deer of all species but the Chinese Water deer and female reindeer grow and shed new antlers each year. In this they differ from permanently horned animals such as antelope; these are in the same order as deer and may bear a superficial resemblance. The musk deer of Asia and Water Chevrotain (or Mouse Deer) of tropical African and Asian forests are not usually regarded as true deer and form their own families, Moschidae and Tragulidae, respectively.

Terminology

The word "deer" was originally quite broad in meaning, but became more specific over time. In Middle English der (O.E. dēor) meant a wild animal of any kind (as opposed to cattle, which then meant any domestic livestock, from the idea of ownership and related to chattle and capital).[1] This general sense gave way to the modern sense by the end of the Middle English period, around 1500. Cognates of English "deer" in several other languages still have the general sense of "animal" – for example German Tier, Dutch dier, and Scandinavian djur, dyr, dýr. "Deer" is the same in the plural as in the singular.

For most deer the male is called a buck and the female is a doe, but the terms vary with dialect, and especially according to the size of the species. For many larger deer the male is a stag and the female a hind, while for other larger deer the same words are used as for cattle: bull and cow. Terms for young deer vary similarly, with that of most being called a fawn and that of the larger species calf; young of the smallest kinds may be a kid. A group of deer of any kind is a herd.The adjective of relation pertaining to deer is cervine; like the family name "Cervidae" this is from Latin: cervus, "deer".

The word 'hart' is an old alternative word for "stag", especially in a (British) Medieval hunting context.

Habitat

Deer are widely distributed, and hunted, with indigenous representatives in all continents except Antarctica and Australia, though Africa has only one native species, the Red Deer, confined to the Atlas Mountains in the northwest of the continent.

Deer live in a variety of biomes ranging from tundra to the tropical rainforest. While often associated with forests, many deer are ecotone species that live in transitional areas between forests and thickets (for cover) and prairie and savanna (open space). The majority of large deer species inhabit temperate mixed deciduous forest, mountain mixed coniferous forest, tropical seasonal/dry forest, and savanna habitats around the world. Clearing open areas within forests to some extent may actually benefit deer populations by exposing the understory and allowing the types of grasses, weeds, and herbs to grow that deer like to eat. Additionally, access to adjacent croplands may also benefit deer. However, adequate forest or brush cover must still be provided for populations to grow and thrive.

Small species of brocket deer and pudús of Central and South America, and muntjacs of Asia generally occupy dense forests and are less often seen in open spaces, with the possible exception of the Indian Muntjac. There are also several species of deer that are highly specialized, and live almost exclusively in mountains, grasslands, swamps, and "wet" savannas, or riparian corridors surrounded by deserts. Some deer have a circumpolar distribution in both North America and Eurasia. Examples include the caribou that live in Arctic tundra and taiga (boreal forests) and moose that inhabit taiga and adjacent areas. Huemul Deer (taruca and Chilean Huemul) of South America's Andes fill an ecological niche of the ibex or Wild Goat, with the fawns behaving more like goat kids.

The highest concentration of large deer species in temperate North America lies in the Canadian Rocky Mountain and Columbia Mountain Regions between Alberta and British Columbia where all five North American deer species (White-tailed deer, Mule deer, Caribou, Elk, and Moose) can be found. This region has several clusters of national parks including Mount Revelstoke National Park, Glacier National Park (Canada), Yoho National Park, and Kootenay National Park on the British Columbia side, and Banff National Park, Jasper National Park, and Glacier National Park (U.S.) on the Alberta and Montana sides. Mountain slope habitats vary from moist coniferous/mixed forested habitats to dry subalpine/pine forests with alpine meadows higher up. The foothills and river valleys between the mountain ranges provide a mosaic of cropland and deciduous parklands. The rare woodland caribou have the most restricted range living at higher altitudes in the subalpine meadows and alpine tundra areas of some of the mountain ranges. Elk and Mule Deer both migrate between the alpine meadows and lower coniferous forests and tend to be most common in this region. Elk also inhabit river valley bottomlands, which they share with White-tailed deer. The White-tailed deer have recently expanded their range within the foothills and river valley bottoms of the Canadian Rockies owing to conversion of land to cropland and the clearing of coniferous forests allowing more deciduous vegetation to grow up the mountain slopes. They also live in the aspen parklands north of Calgary and Edmonton, where they share habitat with the moose. The adjacent Great Plains grassland habitats are left to herds of Elk, American Bison, and pronghorn antelope.

The Eurasian Continent (including the Indian Subcontinent) boasts the most species of deer in the world, with most species being found in Asia. Europe, in comparison, has lower diversity in plant and animal species. However, many national parks and protected reserves in Europe do have populations of Red Deer, Roe Deer, and Fallow Deer. These species have long been associated with the continent of Europe, but also inhabit Asia Minor, the Caucasus Mountains, and Northwestern Iran. "European" Fallow Deer historically lived over much of Europe during the Ice Ages, but afterwards became restricted primarily to the Anatolian Peninsula, in present-day Turkey. Present-day Fallow deer populations in Europe are a result of historic man-made introductions of this species first to the Mediterranean regions of Europe, then eventually to the rest of Europe. They were initially park animals that later escaped and reestablished themselves in the wild. Historically, Europe's deer species shared their deciduous forest habitat with other herbivores such as the extinct tarpan (forest horse), extinct aurochs (forest ox), and the endangered wisent (European bison). Good places to see deer in Europe include the Scottish Highlands, the Austrian Alps, and the wetlands between Austria, Hungary, and Czech Republic. Some fine National Parks include Doñana National Park in Spain, the Veluwe in the Netherlands, the Ardennes in Belgium, and Białowieża National Park of Poland. Spain, Eastern Europe, and the Caucasus Mountains still have virgin forest areas that are not only home to sizable deer populations but also for other animals that were once abundant such as the wisent, Eurasian Lynx, Spanish lynx, wolves, and Brown Bears.

The highest concentration of large deer species in temperate Asia occurs in the mixed deciduous forests, mountain coniferous forests, and taiga bordering North Korea, Manchuria (Northeastern China), and the Ussuri Region (Russia). These are among some of the richest deciduous and coniferous forests in the world where one can find Siberian Roe Deer, Sika Deer, Elk, and Moose. Asian Caribou occupy the northern fringes of this region along the Sino-Russian border.

Deer such as the Sika Deer, Thorold's deer, Central Asian Red Deer, and Elk have historically been farmed for their antlers by Han Chinese, Turkic peoples, Tungusic peoples, Mongolians, and Koreans. Like the Sami people of Finland and Scandinavia, the Tungusic peoples, Mongolians, and Turkic peoples of Southern Siberia, Northern Mongolia, and the Ussuri Region have also taken to raising semi-domesticated herds of Asian Caribou.

The highest concentration of large deer species in the tropics occurs in Southern Asia in Northern India's Indo-Gangetic Plain Region and Nepal's Terai Region. These fertile plains consist of tropical seasonal moist deciduous, dry deciduous forests, and both dry and wet savannas that are home to Chital, Hog Deer, Barasingha, Indian Sambar, and Indian Muntjac. Grazing species such as the endangered Barasingha and very common Chital are gregarious and live in large herds. Indian Sambar can be gregarious but are usually solitary or live in smaller herds. Hog Deer are solitary and have lower densities than Indian Muntjac. Deer can be seen in several national parks in India, Nepal, and Sri Lanka of which Kanha National Park, Dudhwa National Park, and Chitwan National Park are most famous. Sri Lanka's Wilpattu National Park and Yala National Park have large herds of Indian Sambar and Chital. The Indian sambar are more gregarious in Sri Lanka than other parts of their range and tend to form larger herds than elsewhere.

The Chao Praya River Valley of Thailand was once primarily tropical seasonal moist deciduous forest and wet savanna that hosted populations of Hog Deer, the now-extinct Schomburgk's Deer, the Eld's Deer, Indian Sambar, and Indian Muntjac. Both the Hog Deer and Eld's Deer are rare, whereas Indian Sambar and Indian Muntjac thrive in protected national parks such as Khao Yai.

Many of these South Asian and Southeast Asian deer species also share their habitat with various herbivores such as Asian Elephants, various Asian rhinoceros species, various antelope species (such as nilgai, Four-horned Antelope, blackbuck, and Indian gazelle in India), and wild oxen (such as Wild Asian Water Buffalo, gaur, banteng, and kouprey). How different herbivores can survive together in a given area is each species have different food preferences, although there may be some overlap.

Australia has six introduced species of deer that have established sustainable wild populations from acclimatisation society releases in the 19th century. These are Fallow Deer, Red Deer, Sambar Deer, Hog Deer, Rusa deer, and Chital. Red Deer introduced into New Zealand in 1851 from English and Scottish stock were domesticated in deer farms by the late 1960s and are common farm animals there now. Seven other species of deer were introduced into New Zealand but none are as widespread as Red Deer.

Biology

Deer weights generally range from 40 to 200 kilograms. They generally have lithe, compact bodies and long, powerful legs suited for rugged woodland terrain. Deer are also excellent jumpers and swimmers. Deer are ruminants, or cud-chewers, and have a four-chambered stomach. The teeth of deer are adapted to feeding on vegetation, and like other ruminants, they lack upper incisors, instead having a tough pad at the front of their upper jaw. Some deer, such as those on the island of Rùm[, do consume meat when it is available. The Chinese water deer, Tufted deer and muntjac have enlarged upper canine teeth forming sharp tusks, while other species often lack upper canines altogether. The cheek teeth of deer have crescent ridges of enamel, which enable them to grind a wide variety of vegetation. The dental formula for deer is:
Dentition
0.0-1.3.3
3.1.3.3

Nearly all deer have a facial gland in front of each eye. The gland contains a strongly scented pheromone, used to mark its home range. Bucks of a wide range of species open these glands wide when angry or excited. All deer have a liver without a gallbladder. Deer also have a tapetum lucidum which gives them sufficiently good night vision.

Nearly all cervids are so-called uniparental species: the fawns are cared for by the mother only. A doe generally has one or two fawns at a time (triplets, while not unknown, are uncommon). The gestation period is anywhere up to ten months for the European Roe Deer. Most fawns are born with their fur covered with white spots, though in many species they lose these spots by the end of their first winter. In the first twenty minutes of a fawn's life, the fawn begins to take its first steps. Its mother licks it clean until it is almost free of scent, so predators will not find it. Its mother leaves often, and the fawn does not like to be left behind. Sometimes its mother must gently push it down with her foot.[6] The fawn stays hidden in the grass for one week until it is strong enough to walk with its mother. The fawn and its mother stay together for about one year. A male usually never sees his mother again, but females sometimes come back with their own fawns and form small herds.
Fawn

Deer are selective feeders. They are usually browsers, and primarily feed on leaves. They have small, unspecialized stomachs by ruminant standards, and high nutrition requirements. Rather than attempt to digest vast quantities of low-grade, fibrous food as, for example, sheep and cattle do, deer select easily digestible shoots, young leaves, fresh grasses, soft twigs, fruit, fungi, and lichens.

Antlers

With the exception of the Chinese Water Deer, which have tusks, all male deer have antlers. Sometimes a female will have a small stub. The only female deer with antlers are Reindeer (Caribou). Antlers grow as highly vascular spongy tissue covered in a skin called velvet. Before the beginning of a species' mating season, the antlers calcify under the velvet and become hard bone. The velvet is then rubbed off leaving dead bone which forms the hard antlers. After the mating season, the pedicle and the antler base are separated by a layer of softer tissue, and the antler falls off.
White-tailed deer

One way that many hunters are able to track main paths that the deer travel on is because of their "rubs". A rub is used to deposit scent from glands near the eye and forehead and physically mark territory.

During the mating season, bucks use their antlers to fight one another for the opportunity to attract mates in a given herd. The two bucks circle each other, bend back their legs, lower their heads, and charge.

Each species has its own characteristic antler structure – for example white-tailed deer antlers include a series of tines sprouting upward from a forward-curving main beam, while Fallow Deer and Moose antlers are palmate, with a broad central portion. Mule deer (and Black-tailed Deer), species within the same genus as the white-tailed deer, instead have bifurcated (or branched) antlers—that is, the main beam splits into two, each of which may split into two more. Young males of many deer, and the adults of some species, such as brocket deer and pudus, have antlers which are single spikes.

Piebald Deer

A piebald deer is a deer with a brown and white spotting pattern which is not caused by parasites or diseases. They can appear to be almost entirely white. In addition to the non-standard coloration, other differences have been observed: bowing or Roman nose, overly arched spine (scoliosis), long tails, short legs, and underbites.

White Deer

Seneca County, New York State maintains the largest herd of white deer. White pigmented White-tailed Deer began populating the deer population in the area now known as the Conservation Area of the former Seneca Army Depot. The U.S. Army gave the white deer protection while managing the normal colored deer through hunting. The white deer coloration is the result of a recessive gene.

Evolution

The earliest fossil deer including Heteroprox date from the Oligocene of Europe, and resembled the modern muntjacs. Later species were often larger, with more impressive antlers. They rapidly spread to the other continents, even for a time occupying much of northern Africa, where they are now almost wholly absent. Some extinct deer had huge antlers, larger than those of any living species. Examples include Eucladoceros, and the giant deer Megaloceros, whose antlers stretched to 3.5 metres across.

Economic significance

Deer have long had economic significance to humans. Deer meat, for which they are hunted and farmed, is called venison. Deer organ meat is called humble. See humble pie.

The Sami of Scandinavia and the Kola Peninsula of Russia and other nomadic peoples of northern Asia use reindeer for food, clothing, and transport.

The caribou in North America is not domesticated or herded as is the case of reindeer (the same species), reindeer are often found in colder regions in Europe, but is important as a quarry animal to the Inuit. Most commercial venison in the United States is imported from New Zealand.

Deer were originally brought to New Zealand by European settlers, and the deer population rose rapidly. This caused great environmental damage and was controlled by hunting and poisoning until the concept of deer farming developed in the 1960s. Deer farming has advanced into a significant economic activity in New Zealand with more than 3,000 farms running over 1 million deer in total. Deer products are exported to over 50 countries around the world, with New Zealand becoming well recognised as a source of quality venison and co-products.

Automobile collisions with deer can impose a significant cost on the economy. In the U.S., about 1.5 million deer-vehicle collisions occur each year, according to the National Highway Traffic Safety Administration. Those accidents cause about 150 human deaths and $1.1 billion in property damage annually.[

Taxonomy

Note that the terms indicate the origin of the groups, not their modern distribution: the water deer, for example, is a New World species but is found only in China and Korea.

It is thought that the new world group originates from the forests of North America and Siberia, the old world deer in Asia.

Hybrid deer

In On the Origin of Species (1859), Charles Darwin wrote "Although I do not know of any thoroughly well-authenticated cases of perfectly fertile hybrid animals, I have some reason to believe that the hybrids from Cervulus vaginalis and Reevesii [...] are perfectly fertile." These two varieties of muntjac are currently considered the same species.

A number of deer hybrids are bred to improve meat yield in farmed deer. American Elk (or Wapiti) and Red Deer from the Old World can produce fertile offspring in captivity, and were once considered one species. Hybrid offspring, however, must be able to escape and defend themselves against predators, and these hybrid offspring are unable to do so in the wild state. Recent DNA, animal behavior studies, and morphology and antler characteristics have shown there are not one but three species of Red Deer: European Red Deer, Central Asian Red Deer, and American Elk or Wapiti. The European Elk is a different species and is known as moose in North America. The hybrids are about 30% more efficient in producing antlers by comparing velvet to body weight. Wapiti have been introduced into some European Red Deer herds to improve the Red Deer type, but not always with the intended improvement.

In New Zealand, where deer are introduced species, there are hybrid zones between Red Deer and North American Wapiti populations and also between Red Deer and Sika Deer populations. In New Zealand, Red Deer have been artificially hybridized with Pere David Deer in order to create a farmed deer which gives birth in spring. The initial hybrids were created by artificial insemination and back-crossed to Red Deer. However, such hybrid offspring can only survive in captivity free of predators.

In Canada, the farming of European Red Deer and Red Deer hybrids is considered a threat to native Wapiti. In Britain, the introduced Sika Deer is considered a threat to native Red Deer. Initial Sika Deer/Red Deer hybrids occur when young Sika stags expand their range into established red deer areas and have no Sika hinds to mate with. They mate instead with young Red hinds and produce fertile hybrids. These hybrids mate with either Sika or Red Deer (depending which species is prevalent in the area), resulting in mongrelization. Many of the Sika Deer which escaped from British parks were probably already hybrids for this reason. These hybrids do not properly inherit survival strategies and can only survive in either a captive state or when there are no predators.

In captivity, Mule Deer have been mated to White-tail Deer. Both male Mule Deer/female White-tailed Deer and male White-tailed Deer/female Mule Deer matings have produced hybrids. Less than 50% of the hybrid fawns survived their first few months. Hybrids have been reported in the wild but are disadvantaged because they don't properly inherit survival strategies. Mule Deer move with bounding leaps (all 4 hooves hit the ground at once, also called "stotting") to escape predators. Stotting is so specialized that only 100% genetically pure Mule Deer seem able to do it. In captive hybrids, even a one-eighth White-tail/seven-eighths Mule Deer hybrid has an erratic escape behaviour and would be unlikely to survive to breeding age. Hybrids do survive on game ranches where both species are kept and where predators are controlled by man.

Cultural significance

Heraldry

Deer are represented in heraldry by the stag or hart, or less often, by the hind, and the brocket (a young stag up to two years), respectively. Stag's heads and antlers also appear as charges. The old name for deer was simply cerf, and it is chiefly the head which appears on the ancient arms. Examples of deer in heraldry can be found in the arms of Hertfordshire, England and its county town of Hertford; both are examples of canting arms.

Several Norwegian municipalities have a stag or stag's head in their arms: Gjemnes, Hitra, Hjartdal, Rendalen and Voss. A deer appears on the arms of the Israeli Postal Authority (see Hebrew Wikipedia page.

Literature and art
For the role of deer in mythology, see deer in mythology.
The Golden Hind was an English galleon best known for its global circumnavigation between 1577 and 1580, captained by Sir Francis Drake.
The deer plays a large role in Scottish Gaelic poetry (fiadh) of the Highlands of Scotland, where it is seen as a noble creature, and ofter used as a flattering simile or metaphor when used in comparison to a famous warrior, hero or chief. Other animals include the salmon and golden eagle. In Cead deirranach nam beinn by Duncan MacIntyre, the bard has a feeling of sadness due to the fact that the slopes upon which he had hunted the noble deer had gone fo chaoraibh (under sheep: become sheep grazing hills, a animal of derision and metaphor since it was the sheep which replaced many Scottish Highlanders in the glens and straths).
The fiction book Fire Bringer is about a young fawn who is born and goes on a quest to save the deer kind who are called the Herla in the novel.
In Christmas lore (such as in the narrative poem "A Visit from St. Nicholas"), reindeer are often depicted pulling the sleigh of Santa Claus.
One famous fictional deer is Bambi. In the Disney film Bambi, he is a white-tailed deer, while in Felix Salten's original book Bambi, A Life in the Woods, he is a roe deer.
The Pulitzer Prize-winning 1938 novel The Yearling, written by Marjorie Kinnan Rawlings, was about a boy's relationship with a baby deer, later adapted to a children's film that was nominated for an Academy Award for Best Picture.
Saint Hubertus saw a stag with a crucifix between its antlers while hunting on Good Friday and was converted to Christianity by the vision. This story was transferred to Hubert from St Eustace, of whom it was originally told.
In The Lion, the Witch and the Wardrobe, the first book in The Chronicles of Narnia series, the adult Pevensies, now kings and queens of Narnia, chase the White Stag on a hunt, as the Stag is said to grant its captor a wish. The hunt is key in returning the Pevensies to their home in England.
In the Harry Potter series, the Patronus Charm that Harry Potter conjures to repel Dementors is a silver stag. James Potter, Harry's father, had an Animagus form as a stag. Also, Harry's mother Lily Potter, and subsequently Severus Snape's, Patronus form was a doe.
In one of the stories of Baron Münchhausen, the baron encounters a stag while eating cherries and without ammunition, fires the cherry-pits at the stag with his musket, but it escapes. The next year, the baron encounters a stag with a cherry tree growing from its head; presumably this is the animal he had shot at the previous year.
A Samurai warrior named Honda Tadakatsu famously adorned deer antlers on his helmet.
Deer have been a subject in Chinese paintings numerous times as a tranquility symbol.

In The Animals of Farthing Wood, a deer called The Great White Stag is the leader of all the animal residents of the nature reserve White Deer Park.
In The Queen, a 14 point "Imperial" stag plays a role in the film.
The Yaqui deer song (maso bwikam) accompanies the deer dance which is performed by a pascola [from the Spanish 'pascua', Easter] dancer (also known as a deer dancer). Pascolas will perform at religio-social functions many times of the year, but especially during Lent and Easter.
Deer are depicted in many materials by various pre-Hispanic civilizations in the Andes.
Several German towns are called "Hirschberg", a name composed of Hirsch (deer) and Berg (hill or mountain).
The given name "Oscar" is considered to be derived from Gaelic, meaning "deer lover."
Among East European Jews, "Hirsh"—Yiddish for "stag"—was a common male name, and was among other others the name of several prominent Rabbis; in this community there was, however, no equivalent female name. In contemporary Israel, several Hebrew names for this animal are commonly used as both male and female names. These include "Tzvi" and "Eyal" two synonymous words for "stag"; "Tzviya" and "Ayala" the respective parallel words for "Hind" or "Doe"; as well as "Ofer" (עופר) and "Ofra"(עפרה), respectively the male and female words for the young of this animal—which are all commonly used as first names among the Israeli population. In addition, there are Israelis having as their first name "Bambi", derived from the well-known Disney animated film.


Among the native Tlingit of southeast Alaska the deer is a symbol of peace, because a deer does not bite, get angry and is gentle. When peace was to be made a "hostage" from opposing clans would be taken to the opposite clan of those making peace and each opposing faction would have a hostage, called Ghuwukaan in a ceremony lasting several months. The name for [Sitka Blacktail] deer is Ghuwukaan. Making peace is called Ghuwukaan Khuwdzitee or "there will be a peace party." A name given to the "hostage" by his captors would be with the term "ghuwukaan" added such as Aank'weiyi Ghuwukaan (Flag Deer) or Dzagitgayaa Ghuwukaan (Hummingbird Deer).

Bear

Bears are mammals of the family Ursidae. Bears are classified as caniforms, or doglike carnivorans, with the pinnipeds being their closest living relatives. Although there are only eight living species of bear, they are widespread, appearing in a wide variety of habitats throughout the Northern Hemisphere and partially in the Southern Hemisphere. Bears are found in the continents of North America, South America, Europe, and Asia.

Common characteristics of modern bears include a large body with stocky legs, a long snout, shaggy hair, plantigrade paws with five nonretractile claws, and a short tail. While the polar bear is mostly carnivorous and the giant panda feeds almost entirely on bamboo, the remaining six species are omnivorous, with largely varied diets including both plants and animals.

With the exceptions of courting individuals and mothers with their young, bears are typically solitary animals. They are generally diurnal, but may be active during the night (nocturnal) or twilight (crepuscular), particularly around humans. Bears are aided by an excellent sense of smell, and despite their heavy build and awkward gait, they can run quickly and are adept climbers and swimmers. In autumn some bear species forage large amounts of fermented fruits which affects their behaviour. Bears use shelters such as caves and burrows as their dens, which are occupied by most species during the winter for a long period of sleep similar to hibernation.

Bears have been hunted since prehistoric times for their meat and fur. To this day, they play a prominent role in the arts, mythology, and other cultural aspects of various human societies. In modern times, the bear's existence has been pressured through the encroachment on its habitats and the illegal trade of bears and bear parts, including the Asian bile bear market. The IUCN lists six bear species as vulnerable or endangered, and even least concern species such as the brown bear are at risk of extirpation in certain countries. The poaching and international trade of these most threatened populations is prohibited, but still ongoing.
Evolutionary history

The family Ursidae is one of nine families in the suborder Caniformia, or "doglike" carnivors, within the order Carnivora. Bears' closest living relatives are the pinnipeds (seals and kin).

The following synapomorphic (derived) traits set bears apart from related families:

presence of an alisphenoid canal
paroccipital processes that are large and not fused to the auditory bullae
auditory bullae are not enlarged
lacrimal bone is vestigial
cheek teeth are bunodont and hence indicative of a broad, hypocarnivorous (non-strictly meat-eating) diet (although hypercarnivorous (strictly meat-eating) taxa are known from the fossil record)
carnassials are flattened

Additionaly, members of this family possess posteriorly oriented M2 postprotocrista molars, elongated m2 molars, and a reduction of the premolars.

Modern bears comprise eight species in three subfamilies: Ailuropodinae (monotypic with the giant panda), Tremarctinae (monotypic with the Spectacled Bear), and Ursinae (containing six species divided into one to three genera, depending upon authority).

Fossil bears

The earliest members of Ursidae belong to the extinct subfamily Amphicynodontinae, including Parictis (late Eocene to early middle Miocene, 38-18 million years (Ma) ago) and the slightly younger Allocyon (early Oligocene, 34-30 Ma), both from North America. These animals looked very different from today's bears, being small and raccoon-like in overall appearance, and a diet perhaps more similar to that of a badger. Parictis does not appear in Eurasia and Africa until the Miocene. It is unclear whether late Eocene ursids were also present in Eurasia, although faunal exchange across the Bering land bridge may have been possible during a major sea level low stand as early as the late Eocene (~37 Ma) and continuing into the early Oligocene.[4] European genera morphologically very similar to Allocyon, and also the much younger American Kolponomos (~18 Ma), are known from the Oligocene, including Amphicticeps and Amphicynodon.
Plithocyon armagnacensis skull

The raccoon-sized, dog-like Cephalogale is the oldest-known member of the subfamily Hemicyoninae which first appeared during the middle Oligocene in Eurasia ~30 Ma ago. The subfamily also includes the younger genera Phoberocyon (~20-15 Ma), and Plithocyon (~15-7 Ma).

A Cephalogale-like species gave rise to the genus Ursavus during the early Oligocene (30-28 Ma); this genus proliferated into many species in Asia and is ancestral to all living bears. Species of Ursavus subsequently entered North America together with Amphicynodon and Cephalogale during the early Miocene (21-18 Ma).

Members of living lineages of bears diverged from Ursavus ~20 Ma ago, likely via the species Ursavus elmensis. Based on genetic and morphological data, the subfamily Ailuropodinae (pandas) was the first to diverge from other living bears ~19 Ma ago, although no fossils of this group have been found pre-dating about 5 Ma.

The New World short-faced bears (Tremarctinae) differenciated from Ursinae following a dispersal event into the Americas during the mid Miocene (~13 Ma).[5] Their earliest fossil representative is Plionarctos in North America (~10-2 Ma). This genus is probably the direct ancestor to the North American short-faced bears (genus Arctodus), the South American short-faced bear (Pararctotherium and Arctotherium), and the spectacled bears, Tremarctos, represented by both an extinct North American species (T. floridanus), and the lone surviving representative of the Tremarctinae, the South American spectacled bear (T. ornatus).

The subfamily Ursinae experienced a dramatic proliferation of taxa ~5.3-4.5 Ma ago coincident with major environmental changes, with the first members of the genus Ursus also appearing around this time. The sloth bear is a modern survivor of one of the earliest lineages to diverge during this radiation event (~5.3 Ma); it took on its peculiar morphology related to its diet on termites and ants no later than by the early Pleistocene. By 3-4 Ma ago, the species Ursus minimus appears in the fossil record of Europe, which apart from size is nearly identical to today's Asiatic black bear. It is likely ancestral to all bears within Ursinae, perhaps aside from the sloth bear. Two lineages evolved from U. minimus, the black bears (including the sun bear, the Asiatic black bear, and the American black bear), and the brown bears. Modern brown bears evolved from U. minimus via Ursus etruscus, which itself is ancestral to both the extinct Pleistocene cave bear and the ancestor of today's brown and polar bears. Species of Ursinae have migrated repeatedly into N. America from Eurasia as early as 4 Ma ago during the early Pliocene.

The fossil record of bears is exceptionally good. Direct ancestor-descendent relationships between individual species are often fairly well-established, with sufficient intermediate forms known to make the precise cut-off between an ancestral and its daughter species subjective.

Other extinct bear genera include Agriarctos, Indarctos, and Agriotherium (sometimes placed within hemicyonids).

Taxonomic revisions of living bear species

The giant panda's taxonomy (subfamily Ailuropodinae) has long been debated. Its original classification by Armand David in 1869 was within the bear genus Ursus, but in 1870 it was reclassified by Alphonse Milne-Edwards to the raccoon family.[8] In recent studies, the majority of DNA analyses suggest that the giant panda has a much closer relationship to other bears and should be considered a member of the family Ursidae.[9] Estimates of divergence dates place the giant panda as the most ancient offshoot among living taxa within Ursidae, having split from other bears 17.9 to 22.1 Ma ago. The red panda was included within Ursidae in the past. However, more recent research does not support such a conclusion and instead places it in its own family Ailuridae, in superfamily Musteloidea along with Mustelidae, Procyonidae, and Mephitidae.[10][11][12] Multiple similarities between the two pandas, including the presence of false thumbs, are thus thought to represent an example of convergent evolution for feeding primarily on bamboo.

There is also evidence that, unlike their neighbors elsewhere, the brown bears of Alaska's ABC islands are more closely related to polar bears than they are to other brown bears in the world. Researchers Gerald Shields and Sandra Talbot of the University of Alaska Fairbanks Institute of Arctic Biology studied the DNA of several samples of the species and found that their DNA is different from that of other brown bears. The researchers discovered that their DNA was unique compared to brown bears anywhere else in the world. The discovery has shown that while all other brown bears share a brown bear as their closest relative, those of Alaska's ABC Islands differ and share their closest relation with the polar bear. There is also the very rare Tibetan Blue Bear, which is a type of brown bear. This animal has never been photographed.

Koalas are often referred to as bears due to their appearance; they are not bears, however, but marsupials.

Biology

Morphology

Bears are generally bulky and robust animals with relatively short legs. Bears are sexually dimorphic with regard to size, with the males being larger. Larger species tend to show increased levels of sexual dimorphism in comparison to smaller species, and where a species varies in size across its distribution individuals from larger sized areas tend also to vary more. Bears are the most massive terrestrial members of the order Carnivora, with some Polar Bears and Brown Bears weighing over 750 kilograms (1,700 lb). As to which species is the largest may depend on whether the assessment is based on which species has the largest individuals (brown bears) or on the largest average size (polar bears). The smallest bears are the Sun Bears of Asia, which weigh an average of 65 kilograms (140 lb) for the males and 45 kilograms (99 lb) for the females.

Unlike other land carnivorans, bears are plantigrade. They distribute their weight toward the hind feet which makes then look lumbering when they walk. They are still quite fast with the brown bear reaching 30 miles per hour (48 km/h) although they are still slower than felines and canines. Bears can stand on their hind feet and sit up straight with remarkable balance. Bears have non-retractable claws which are used for digging, climbing, tearing and catching prey. Their ears are rounded.

Bears have an excellent sense of smell, a better sense of smell in fact than the dogs (Canidae), or possibly any other mammal. This sense of smell is used for signalling between bears (either to warn off rivals or detect mates) and for finding food. Smell is the principal sense used by bears to find most of their diet.

Dentition

Unlike most other members of the Carnivora, bears have relatively undeveloped carnassial teeth, and their teeth are adapted for a diet that includes a significant amount of vegetable matter. The canine teeth are large, and the molar teeth flat and crushing. There is considerable variation in dental formula even within a given species. It has been suggested that this indicates bears are still in the process of evolving from a carnivorous to a predominantly herbivorous diet. Polar bears appear to have secondarily re-evolved fully functional carnassials, as their diet has switched back towards carnivory. The dental formula for living bears is: Upper: 3.1.2-4.2, lower: 3.1.2-4.3

Distribution and habitat
The bears are mostly found in the northern hemisphere, with a single species, the Andean Bear, occurring in South America. The Atlas Bear, a subspecies of the Brown Bear, was the only bear native to Africa. It was distributed in North Africa from Morocco to Libya, but has been extinct since around the 1870s. All the other species are found in North America, Asia and Europe. The most widespread species is the Brown Bear, which occurs from Western Europe eastwards through Asia to the western areas of North America. The American Black Bear is restricted to North America, and the Polar bear is restricted to the Arctic Sea. All the remaining species are Asian.

With the exception of the Polar Bear the bears are mostly forest species. Some species, particularly the Brown Bear, may inhabit or seasonally use other areas such as alpine scrub or tundra.

Behaviour

While many people think that bears are nocturnal, they are in fact generally diurnal, active for the most part during the day. The belief that they are nocturnal apparently comes from the habits of bears that live near humans which engage in some activities, such as raiding trash cans or crops, are nocturnal in order to avoid humans. The sloth bear of Asia is the most nocturnal of the bears, but this varies by individual and females with cubs are often diurnal in order to avoid competition with males and nocturnal predators. Bears are overwhelmingly solitary and are considered to be the most asocial of all the Carnivora. Liaisons between breeding bears are brief, and the only times bears are encountered in small groups are mothers with young or occasional seasonal bounties of rich food (such as salmon runs).

Vocalizations

Bears produce a variety of vocalizations such as:

Moaning: produced mostly as mild warnings to potential threats or in fear.
Barking: produced during times of alarm, excitement or to give away the animal's position.
Huffing: made during courtship or between mother and cubs to warn of danger.
Growling: produced as strong warnings to potential threats or in anger.
Roaring: used much for the same reasons as growls and also to proclaim territory and for intimidation.

Diet and interspecific interactions

Their carnivorous reputation non-withstanding, most bears have adopted a diet of more plant than animal matter and are completely opportunistic omnivores. Some bears will climb trees in order to obtain mast (edible vegatative or reproductive parts such as acorns), smaller species which are more able to climb include a greater amount of this in their diet. Such masts can be very important to the diet of these species, and mast failures may result in long range movements by bears looking for alternate sources of food. One exception is the Polar Bear, which has adopted a diet mainly of marine mammals to survive in the Arctic. The other exception is the Giant Panda which has adopted a diet mainly of bamboo. Stable isotope analysis of the extinct Giant Short-faced Bear (Arctodus simus) shows that it was also an exclusive meat eater, probably a scavenger. The Sloth Bear, though not as specialized as the previous two species, has lost several front teeth usually seen in bears and developed a long, suctioning tongue in order to feed on the ants, termites and other burrowing insects that they favour. At certain times of the year these insects can make up 90% of their diet. All bears will feed on any food source that becomes available, and the nature of that varies seasonally. A study of Asiatic Black Bears in Taiwan found that they would consume large numbers of acorns when they were most common, and switch to ungulates in other times of the year.

When taking warm-blooded animals, bears will typically take small or young animals, as they are easier to catch. Although (besides Polar Bears) both species of black bear and the Brown Bear can sometimes take large prey, such as ungulates. Often, bears will feed on other large animals when they encounter a carcass, whether or not the carcass is claimed by or is the kill of another predator. This competition is the main source of interspecies conflict. Bears are typically the apex predators in their range due to their size and power, and can defend a carcass against nearly all comers. Mother bears also can usually defend their cubs against other predators. The Tiger is the only known predator known to regularly prey on adult bears, including Sloth Bears, Asiatic Black Bears, Giant Pandas, Sun Bears and small Brown Bears.

Breeding

The age at which bears reach sexual maturity is highly variable, both between and within species. Sexual maturity is dependent on body condition, which is in turn dependent upon the food supply available to the growing individual. In the females of smaller species may have young in as little as two years, whereas the larger species may not rear young until they are four or even nine years old. First breeding may be even later in males, where competition for mates may leave younger males without access to females.

The bear's courtship period is very brief. Bears in northern climates reproduce seasonally, usually after a period of inactivity similar to hibernation, although tropical species breed all year round. Cubs are born toothless, blind, and bald. The cubs of brown bears, usually born in litters of 1–3, will typically stay with the mother for two full seasons. They feed on their mother's milk through the duration of their relationship with their mother, although as the cubs continue to grow, nursing becomes less frequent and cubs learn to begin hunting with the mother. They will remain with the mother for approximately three years, until she enters the next cycle of estrus and drives the cubs off. Bears will reach sexual maturity in five to seven years. Male bears, especially Polar and Brown Bears, will kill and sometimes devour cubs born to another father in order to induce a female to breed again. Female bears are often successful in driving off males in protection of their cubs, despite being rather smaller.

Winter dormancy

Many bears of northern regions are assumed to hibernate in the winter. While many bear species do go into a physiological state often colloquially called "hibernation" or "winter sleep", it is not true hibernation. In true hibernators, body temperatures drop to near ambient and heart rate slows drastically, but the animals periodically rouse themselves to urinate or defecate and to eat from stored food. The body temperature of bears, on the other hand, drops only a few degrees from normal and heart rate slows only slightly. They normally do not wake during this "hibernation", and therefore do not eat, drink, urinate or defecate the entire period. Higher body heat and being easily roused may be adaptations, because females give birth to their cubs during this winter sleep.

Relationship with humans

See also: Bear danger
Some species, such as the polar bear, American black bear, Sloth Bear and the brown bear, are dangerous to humans, especially in areas where they have become used to people. All bears are physically powerful and are likely capable of fatally attacking a person, but they, for the most part, are shy, are easily frightened and will avoid humans. Injuries caused by bears are rare, but are often widely reported.[ The danger that bears pose is often vastly exaggerated, in part by the human imagination. However, when a mother feels her cubs are threatened, she will behave ferociously. It is recommended to give all bears a wide berth because they are behaviorally unpredictable.

Bears may also come into conflict with humans where they raid crops or attack livestock. These problems may be the work of only a few bears but create a climate of conflict as farmers and ranchers may perceive all losses as due to bears and advocate the preventive removal of all bears. Mitigation methods may be used to reduce bear damage to crops, and reduce local antipathy towards bears.

Laws have been passed in many areas of the world to protect bears from hunters' habitat destruction. Public perception of bears is often very positive, as people identify with bears due to their omnivorous diet, ability to stand on two legs, and symbolic importance, and there is widespread support for bear protection, at least in more affluent societies. In more rural and poorer regions attitudes may be more shaped by the dangers posed by bears and the economic costs that they incur to farmers and ranchers. Some populated areas with bear populations have also outlawed the feeding of bears, including allowing them access to garbage or other food waste. Bears in captivity have been trained to dance, box, or ride bicycles; however, this use of the animals became controversial in the late 20th century. Bears were kept for baiting in Europe at least since the 16th century.

Bears as food and medicine
Many people enjoy hunting bears and eating them. Their meat is dark and stringy, like a tough cut of beef. In Cantonese cuisine, bear paws are considered a delicacy. The peoples of China, Japan, and Korea use bears' body parts and secretions (notably their gallbladders and bile) as part of traditional Chinese medicine. It is believed more than 12,000 bile bears are kept on farms, farmed for their bile, in China, Vietnam and South Korea. Bear meat must be cooked thoroughly as it can often be infected with trichinellosis.

Culture

Names

The English word "bear" comes from Old English bera and belongs to a family of names for the bear in Germanic languages, in origin from an adjective meaning "brown".[31] In Scandinavia the word for bear is björn (or bjørn), and is a relatively common given name for males. The use of this name is ancient and has been found mentioned in several runestone inscriptions. In Germanic culture, the bear was a symbol of the warrior, as evident from the Old English term beorn which can take the meaning of both "bear" and "warrior".

The reconstructed Proto-Indo-European name of the bear is *h₂ŕ̥tḱos, whence Sanskrit r̥kṣa, Avestan arša, Greek ἄρκτος, Latin ursus, Welsh arth (whence perhaps the given name "Arthur"). Also compared is Hittite ḫartagga-, the name of a monster or predator. In the binomial name of the brown bear, Ursus arctos, Linné simply combined the Latin and Greek names. The female first name "Ursula", originally derived from a Christian saint's name and common in English- and German-speaking countries, means "little she-bear" (dimunitive of Latin ursa). In Switzerland the male first name "Urs" is especially popular.

In Russian and other Slavic languages, the word for bear, "Medved" (медведь), and variants or derivatives such as Medvedev are common surnames.

The Irish family name "McMahon" means "Son of Bear" in Irish.

In East European Jewish communities, the name "Ber" Yiddish cognate of "Bear" has been attested as a common male first name, at least since the 18th century, and was among others the name of several prominent Rabbis. The Yiddish "Ber" is still in use among Orthodox Jewish communities in Israel, the US and other countries.

With the transition from Yiddish to Hebrew under the influence of Zionism, the Hebrew word for "bear", "Dov" , was taken up in contemporary Israel and is at present among the commonly used male first names in that country.

"Ten Bears" (Paruasemana) was the name of a well-known 19th Century chieftain among the Comanche. Also among other Native American tribes, bear-related names are attested.

Myth and legend

There is evidence of prehistoric bear worship, see Arctic, Arcturus, Great Bear, Berserker, Kalevala. Anthropologists such as Joseph Campbell have regarded this as a common feature in most of the fishing and hunting-tribes. The prehistoric Finns, along with most Finno-Ugric peoples, considered the bear as the spirit of one's forefathers. This is why the bear (karhu) was a greatly respected animal, with several euphemistic names (such as otso, mesikämmen and kontio). The bear is the national animal of Finland.

This kind of attitude is reflected in the traditional Russian fairy tale "Morozko", whose arrogant protagonist Ivan tries to kill a mother bear and her cubs and is punished and humbled by having his own head turned magically into a bear's head and being subsequently shunned by human society.

"The Brown Bear of Norway" is a Scottish fairy tale telling the adventures of a girl who married a prince magically turned into a bear, and who managed to get him back into a human form by the force of her love and after many trials and difficulties.

There has been evidence about early bear worship in China and among the Ainu culture as well (see Iomante). Korean people in their mythology identify the bear as their ancestor and symbolic animal. According to the Korean legend, a god imposed a difficult test on a she-bear, and when she passed it the god turned her into a woman and married her.

In addition, the Proto-Indo-European word for bear, *h₂ŕ̥tḱos (ancestral to the Greek arktos, Latin ursus, Welsh arth (cf. Arthur), Albanian ari, Armenian arj, Sanskrit ṛkṣa, Hittite ḫartagga) seems to have been subject to taboo deformation or replacement in some languages (as was the word for wolf, wlkwos), resulting in the use of numerous unrelated words with meanings like "brown one" (English bruin) and "honey-eater" (Slavic medved). Thus some Indo-European language groups do not share the same PIE root. The theory of the bear taboo is taught to almost all beginning students of Indo-European and historical linguistics; the putative original PIE word for bear is itself descriptive, because a cognate word in Sanskrit is rakṣas, meaning "harm, injury".
The saddled "bear of St. Corbinian" the emblem of Freising, here incorporated in the arms of Pope Benedict

Legends of saints taming bears are common in the Alpine zone. In the arms of the bishopric of Freising (see illustration) the bear is the dangerous totem animal tamed by St. Corbinian and made to carry his civilised baggage over the mountains. A bear also features prominently in the legend of St. Romedius, who is also said to have tamed one of these animals and had the same bear carry him from his hermitage in the mountains to the city of Trento.
Coat of Arms of the Abbey of Saint Gall

Similar stories are told of Saint Gall and Saint Columbanus.

This recurrent motif was used by the Church as a symbol of the victory of Christianity over Paganism, represented by the fiery.
"The Three Bears", Arthur Rackham's illustration to English Fairy Tales, by Flora Annie Steel

Bears are a popular feature of many children's stories including Goldilocks and the Three Bears, the Berenstein Bears, and Winnie the Pooh.

The constellations Ursa Major and Ursa Minor represent bears.

Symbolic use

The Russian bear is a common National personification for Russia (as well as the Soviet Union) and even Germany. The brown bear is Finland's national animal.
The flag of California

In the United States, the black bear is the state animal of Louisiana, New Mexico, and West Virginia; the grizzly bear is the state animal of both Montana and California.

Bears appear in the canting arms of Bern and Berlin.

Also, "bear", "bruin", or specific types of bears are popular nicknames or mascots, e.g. for sports teams (Chicago Bears, California Golden Bears, UCLA Bruins, Boston Bruins); and a bear cub called Misha was mascot of the 1980 Summer Olympics in Moscow, USSR. Smokey Bear

Smokey Bear has become a part of American culture since his introduction in 1944. Known to almost all Americans, he and his message, "Only You Can Prevent Forest Fires" (updated in 2001 to "Only You Can Prevent Wildfires") has been a symbol of preserving woodlands. Smokey wears a hat similar to one worn by many U.S. state police officers, giving rise to the CB slang "bear" or "Smokey" for the highway patrol.

Figures of speech
The physical attributes and behaviours of bears are commonly used in figures of speech in English.

In the stock market, a bear market is a period of declining prices. Pessimistic forecasting or negative activity is said to be bearish (due to the stereotypical posture of bears looking downwards), and one who expresses bearish sentiment is a bear. Its opposite is a bull market, and bullish sentiment from bulls.
In gay slang, the term "bear" refers to male individuals who possess physical attributes much like a bear, such as a heavy build, abundant body hair, and commonly facial hair.
A bear hug is typically a tight hug that involves wrapping one's arms around another person, often leaving that person's arms immobile. It was used in the Ronald Reagan political ad "Bear in the woods."
Bear tracking - in the old Western states of the U.S. and to this day in the former Dakota Territory, the expression, "You ain't just a bear trackin'.", is used to mean "You ain't lying" or "That's for sure" or "You're not just blowing smoke". This expression evolved as an outgrowth of the experience pioneer hunters and mountainmen had when tracking bear. Bears often lay down false tracks and are notorious for doubling back on anything tracking them. If you are not following bear tracks, you are not following false trails or leads in your thoughts, words or deeds.
In Korean culture a person is referred to as being "like a bear" when they are stubborn or not sensitive to what is happening around their surroundings. Used as a phrase to call a person "stubborn bear."
The Bible compares King David's "bitter warriors", who fight with such fury that they could overcome many times their number of opponents, with "a bear robbed of her whelps in the field" (2 Samuel 17:8 s:Bible (King James)/2 Samuel#Chapter 17). The term "a bereaved bear" (דב שכול), derived from this Biblical source, is still used in the literary Hebrew of contemporary Israel.

Cheetah


The cheetah (Acinonyx jubatus) is an atypical member of the cat family (Felidae) that is unique in its speed, while lacking strong climbing abilities. The species is the only living member of the genus Acinonyx. It is the fastest land animal, reaching speeds between 112 and 120 km/h (70 and 75 mph) in short bursts covering distances up to 460 m (1,510 ft), and has the ability to accelerate from 0 to 103 km/h (64 mph) in three seconds, faster than most supercars. Recent studies confirm the cheetah's status as the fastest land animal.

The word "cheetah" is derived from the Sanskrit word citrakāyaḥ, meaning "variegated body", via the Hindi चीता cītā

Genetics and classification

The genus name, Acinonyx, means "no-move-claw" in Greek, while the species name, jubatus, means "maned" in Latin, a reference to the mane found in cheetah cubs.

The cheetah has unusually low genetic variability and a very low sperm count, which also suffers from low motility and deformed flagella. Skin grafts between non-related cheetahs illustrate this point in that there is no rejection of the donor skin. It is thought that it went through a prolonged period of inbreeding following a genetic bottleneck during the last ice age. It probably evolved in Africa during the Miocene epoch (26 million to 7.5 million years ago), before migrating to Asia. New research by a team led by Warren Johnson and Stephen O'Brien of the Laboratory of Genomic Diversity (National Cancer Institute in Frederick, Maryland, United States) has recently placed the last common ancestor of all existing species as living in Asia 11 million years ago, which may lead to revision and refinement of existing ideas about cheetah evolution. Now-extinct species include: Acinonyx pardinensis (Pliocene epoch), much larger than the modern cheetah and found in Europe, India, and China; Acinonyx intermedius (mid-Pleistocene period), found over the same range. The extinct genus Miracinonyx was extremely cheetah-like, but recent DNA analysis has shown that Miracinonyx inexpectatus, Miracinonyx studeri, and Miracinonyx trumani (early to late Pleistocene epoch), found in North America and called the "North American cheetah" are not true cheetahs, instead being close relatives to the cougar.

Subspecies

Although many sources list six or more subspecies of cheetah, the taxonomic status of most of these subspecies is unresolved. Acinonyx rex—the king cheetah (see below)—was abandoned after it was discovered the variation was only a recessive gene. The subspecies Acinonyx jubatus guttatus, the woolly cheetah, may also have been a variation due to a recessive gene. Some of the most commonly recognized subspecies include

Asiatic Cheetah (Acinonyx jubatus venaticus): Asia (Afghanistan, India, Iran, Iraq, Israel, Jordan, Oman, Pakistan, Saudi Arabia, Syria, Russia)
Northwest African Cheetah (Acinonyx jubatus hecki): Northwest Africa (Algeria, Djibouti, Egypt, Mali, Mauritania, Morocco, Niger, Tunisia and Western Sahara) and western Africa (Benin, Burkina Faso, Ghana, Mali, Mauritania, Niger, and Senegal)
Acinonyx jubatus raineyii: eastern Africa (Kenya, Somalia, Tanzania, and Uganda)
Acinonyx jubatus jubatus: southern Africa (Angola, Botswana, Democratic Republic of the Congo, Mozambique, Malawi, South Africa, Tanzania, Zambia, Zimbabwe and Namibia)
Acinonyx jubatus soemmeringii: central Africa (Cameroon, Chad, Central African Republic, Ethiopia, Nigeria, Niger, and Sudan)
Acinonyx jubatus velox

Description

The cheetah's chest is deep and its waist is narrow. The coarse, short fur of the cheetah is tan with round black spots measuring from 2 to 3 cm (0.79 to 1.2 in) across, affording it some camouflage while hunting. There are no spots on its white underside, but the tail has spots, which merge to form four to six dark rings at the end. The tail usually ends in a bushy white tuft. The cheetah has a small head with high-set eyes. Black "tear marks" run from the corner of its eyes down the sides of the nose to its mouth to keep sunlight out of its eyes and to aid in hunting and seeing long distances. Although it can reach high speeds, its body cannot stand long distance running. It is a sprinter.

The adult cheetah weighs from 36 to 65 kg (79 to 140 lb). Its total body length is from 115 to 135 cm (45 to 53 in), while the tail can measure up to 84 cm (33 in) in length. Cheetah are 67 to 94 cm (26 to 37 in) in high at the shoulder. Males tend to be slightly larger than females and have slightly bigger heads, but there is not a great variation in cheetah sizes and it is difficult to tell males and females apart by appearance alone. Compared to a similarly sized leopard, the cheetah is generally shorter-bodied, but is longer tailed and taller (it averages about 90 cm (35 in) tall) and so it appears more streamlined.

Some cheetahs also have a rare fur pattern mutation: cheetahs with larger, blotchy, merged spots are known as "king cheetahs". It was once thought to be a separate subspecies, but it is merely a mutation of the African cheetah. The "king cheetah" has only been seen in the wild a handful of times, but it has been bred in captivity.

The cheetah's paws have semi-retractable claws (known only in three other cat species: the Fishing Cat, the Flat-headed Cat and the Iriomote Cat) offering extra grip in its high-speed pursuits. The ligament structure of the cheetah's claws is the same as those of other cats; it simply lacks the sheath of skin and fur present in other varieties, and therefore the claws are always visible, with the exception of the dewclaw. The dewclaw itself is much shorter and straighter than that of other cats.

Adaptations that enable the cheetah to run as fast as it does include large nostrils that allow for increased oxygen intake, and an enlarged heart and lungs that work together to circulate oxygen efficiently. During a typical chase its respiratory rate increases from 60 to 150 breaths per minute. While running, in addition to having good traction due to its semi-retractable claws, the cheetah uses its tail as a rudder-like means of steering[citation needed] to allow it to make sharp turns, necessary to outflank prey animals that often make such turns to escape.

Unlike "true" big cats, the cheetah can purr as it inhales, but cannot roar. By contrast, the big cats can roar but cannot purr, except while exhaling. However, the cheetah is still considered by some to be the smallest of the big cats. While it is often mistaken for the leopard, the cheetah does have distinguishing features, such as the aforementioned long "tear-streak" lines that run from the corners of its eyes to its mouth. The body frame of the cheetah is also very different from that of the leopard, most notably so in its thinner and longer tail and, unlike the leopard's, its spots are not arranged into rosettes.

The cheetah is a vulnerable species. Out of all the big cats, it is the least able to adapt to new environments. It has always proved difficult to breed in captivity, although recently a few zoos have managed to succeed at this. Once widely hunted for its fur, the cheetah now suffers more from the loss of both habitat and prey.

The cheetah was formerly considered to be particularly primitive among the cats and to have evolved approximately 18 million years ago. New research, however, suggests that the last common ancestor of all 40 existing species of felines lived more recently than that—about 11 million years ago. The same research indicates that the cheetah, while highly derived morphologically, is not of particularly ancient lineage, having separated from its closest living relatives (Puma concolor, the cougar, and Puma yaguarondi, the jaguarundi) around five million years ago. These felids have not changed appreciably since they first appeared in the fossil record.

Morphs and variations

The king cheetah is a rare mutation of cheetah characterized by a distinct fur pattern. It was first noted in what was then Southern Rhodesia (modern-day Zimbabwe) in 1926. In 1927, the naturalist Reginald Innes Pocock declared it a separate species, but reversed this decision in 1939 due to lack of evidence, but in 1928, a skin purchased by Walter Rothschild was found to be intermediate in pattern between the king cheetah and spotted cheetah and Abel Chapman considered it to be a color form of the spotted cheetah. Twenty-two such skins were found between 1926 and 1974. Since 1927, the king cheetah was reported five more times in the wild. Although strangely marked skins had come from Africa, a live king cheetah was not photographed until 1974 in South Africa's Kruger National Park. Cryptozoologists Paul and Lena Bottriell photographed one during an expedition in 1975. They also managed to obtain stuffed specimens. It appeared larger than a spotted cheetah and its fur had a different texture. There was another wild sighting in 1986—the first in seven years. By 1987, thirty-eight specimens had been recorded, many from pelts.

Its species status was resolved in 1981 when king cheetahs were born at the De Wildt Cheetah and Wildlife Centre in South Africa. In May 1981, two spotted sisters gave birth there and each litter contained one king cheetah. The sisters had both mated with a wild-caught male from the Transvaal area (where king cheetahs had been recorded). Further king cheetahs were later born at the Centre. It has been known to exist in Zimbabwe, Botswana and in the northern part of South Africa's Transvaal province. A recessive gene must be inherited from both parents in order for this pattern to appear- which is one reason why it is so rare.

Other color variations

Other rare color morphs of the species include speckles, melanism, albinism and gray coloration. Most have been reported in Indian cheetahs, particularly in captive specimens kept for hunting.

The Mughal Emperor of India, Jahangir, recorded having a white cheetah presented to him in 1608. In the memoirs of Tuzk-e-Jahangiri, the Emperor says that in the third year of his reign: Raja Bir Singh Deo brought a white cheetah to show me. Although other sorts of creatures, both birds and beasts have white varieties .... I had never seen a white cheetah. Its spots, which are (usually) black, were of a blue colour, and the whiteness of the body also inclined to blue-ishness. This suggests a chinchilla mutation which restricts the amount of pigment on the hair shaft. Although the spots were formed of black pigment, the less dense pigmentation gives a hazy, grayish effect. As well as Jahangir's white cheetah at Agra, a report of "incipient albinism" has come from Beaufort West according to Guggisberg.

In a letter to "Nature in East Africa", H. F. Stoneham reported a melanistic cheetah (black with ghost markings) in the Trans-Nzoia District of Kenya in 1925. Vesey Fitzgerald saw a melanistic cheetah in Zambia in the company of a spotted cheetah. Red (erythristic) cheetahs have dark tawny spots on a golden background. Cream (isabelline) cheetahs have pale red spots on a pale background. Some desert region cheetahs are unusually pale; probably they are better-camouflaged and therefore better hunters and more likely to breed and pass on their paler coloration. Blue (Maltese or grey) cheetahs have variously been described as white cheetahs with grey-blue spots (chinchilla) or pale grey cheetahs with darker grey spots (Maltese mutation). A cheetah with hardly any spots was shot in Tanzania on 1921 (Pocock), it had only a few spots on the neck and back and these were unusually small.

Range and habitat

There are several geographically isolated populations of cheetah, all of which are found in Africa or Southwestern Asia. A small population (estimated at about fifty) survive in the Khorasan Province of Iran, where conservationists are taking steps to protect them. It is possible, though doubtful, that some cheetahs remain in India. There have also been several unconfirmed reports of Asiatic Cheetahs in the Balochistan province of Pakistan, with at least one dead animal being discovered recently.

The cheetah thrives in areas with vast expanses of land where prey is abundant. The cheetah likes to live in an open biotope, such as semi-desert, prairie, and thick brush, though it can be found in a variety of habitats. In Namibia, for example, it lives in grasslands, savannahs, areas of dense vegetation, and mountainous terrain.

In much of its former range, the cheetah was tamed by aristocrats and used to hunt antelopes in much the same way as is still done with members of the greyhound group of dogs.

Reproduction and behavior

Females reach maturity in twenty to twenty-four months, and males around twelve months (although they do not usually mate until at least three years old), and mating occurs throughout the year. A study of cheetahs in the Serengeti showed that females are sexually promiscuous and often have cubs by many different males.

Females give birth to up to nine cubs after a gestation period of ninety to ninety-eight days, although the average litter size is three to five. Cubs weigh from 150 to 300 g (5.3 to 11 oz) at birth. Unlike some other cats, the cheetah is born with its characteristic spots. Cubs are also born with a downy underlying fur on their necks, called a mantle, extending to mid-back. This gives them a mane or Mohawk-type appearance; this fur is shed as the cheetah grows older. It has been speculated that this mane gives a cheetah cub the appearance of the Honey Badger (Ratel), to scare away potential aggressors. Cubs leave their mother between thirteen and twenty months after birth. Life span is up to twelve years in the wild, but up to twenty years in captivity.

Unlike males, females are solitary and tend to avoid each other, though some mother/daughter pairs have been known to be formed for small periods of time. The cheetah has a unique, well-structured social order. Females live alone except when they are raising cubs and they raise their cubs on their own. The first eighteen months of a cub's life are important; cubs learn many lessons because survival depends on knowing how to hunt wild prey species and avoid other predators. At eighteen months, the mother leaves the cubs, who then form a sibling, or "sib" group, that will stay together for another six months. At about two years, the female siblings leave the group, and the young males remain together for life.

Territories

Males

Males are very sociable and will group together for life, usually with their brothers in the same litter; although if a cub is the only male in the litter then two or three lone males may group up, or a lone male may join an existing group. These groups are called coalitions. In one Serengeti study by Caro and Collins (1987), 41% of the adult males were solitary, 40% lived in pairs and 19% lived in trios.

A coalition is six times more likely to obtain an animal territory than a lone male, although studies have shown that coalitions keep their territories just as long as lone males—between four and four and a half years.

Males are very territorial. Females' home ranges can be very large and trying to build a territory around several females' ranges is impossible to defend. Instead, males choose the points at which several of the females' home ranges overlap, creating a much smaller space, which can be properly defended against intruders while maximizing the chance of reproduction. Coalitions will try their best to maintain territories in order to find females with whom they will mate. The size of the territory also depends on the available resources; depending on the part of Africa, the size of a male's territory can vary greatly from 37 to 160 km2 (14 to 62 sq mi).

Males mark their territory by urinating on objects that stand out, such as trees, logs, or termite mounds. The whole coalition contributes to the scent. Males will attempt to kill any intruders and fights result in serious injury or death.

Females

Unlike males and other felines, females do not establish territories. Instead, the area they live in is termed a home range. These overlap with other females' home ranges, often those of their daughters, mothers, or sisters. Females always hunt alone, although cubs will accompany their mothers to learn to hunt once they reach the age of five to six weeks.

The size of a home range depends entirely on the availability of prey. Cheetahs in southern African woodlands have ranges as small as 34 km2 (13 sq mi), while in some parts of Namibia they can reach 1,500 km (580 sq mi).

Vocalizations

The cheetah cannot roar, but does have the following vocalizations:

Chirping - When cheetahs attempt to find each other, or a mother tries to locate her cubs, it uses a high-pitched barking called chirping. The chirps made by a cheetah cub sound more like a bird chirping, and so are termed chirping.
Churring or stuttering - This vocalization is emitted by a cheetah during social meetings. A churr can be seen as a social invitation to other cheetahs, an expression of interest, uncertainty, or appeasement or during meetings with the opposite sex (although each sex churrs for different reasons).
Growling - This vocalization is often accompanied by hissing and spitting and is exhibited by the cheetah during annoyance, or when faced with danger.
Yowling - This is an escalated version of growling, usually displayed when danger worsens.
Purring - This is made when the cheetah is content, usually during pleasant social meetings (mostly between cubs and their mothers). A characteristic of purring is that it is realised on both egressive and ingressive airstream. A purring cheetah can be heard on Robert Eklund's Ingressive Speech website or on Robert Eklund's Wildlife page .

Diet and hunting

The cheetah is a carnivore, eating mostly mammals under 40 kg (88 lb), including the Thomson's Gazelle, the Grant's gazelle, the springbok and the impala. The young of larger mammals such as wildebeests and zebras are taken at times, and adults too, when the cats hunt in groups. Guineafowl and hares are also prey. While the other big cats mainly hunt by night, the cheetah is a diurnal hunter. It hunts usually either early in the morning or later in the evening when it is not so hot, but there is still enough light.

The cheetah hunts by vision rather than by scent. Prey is stalked to within 10–30 m (33–98 ft), then chased. This is usually over in less than a minute, and if the cheetah fails to make a catch quickly, it will give up. The cheetah has an average hunting success rate of around 50% - half of its chases result in capture.

Running at speeds between 112 and 120 km/h (70 and 75 mph) puts a great deal of strain on the cheetah's body. When sprinting, the cheetah's body temperature becomes so high that it would be deadly to continue; this is why the cheetah is often seen resting after it has caught its prey. If it is a hard chase, it sometimes needs to rest for half an hour or more. The cheetah kills its prey by tripping it during the chase, then biting it on the underside of the throat to suffocate it, for the cheetah is not strong enough to break the necks of the four-legged prey it mainly hunts. The bite may also puncture a vital artery in the neck. Then the cheetah proceeds to devour its catch as quickly as possible before the kill is taken by stronger predators.

The diet of a cheetah is dependent upon the area in which it lives. For example, on the East African plains, its preferred prey is the Thomson's Gazelle. This small antelope is shorter than the cheetah (about 53–67 cm (21–26 in) tall and 70–107 cm (28–42 in) long), and also cannot run faster than the cheetah (only up to 80 km/h (50 mph)), which combine to make it an appropriate prey. Cheetahs look for individuals which have strayed some distance from their group, and do not necessarily seek out old or weak ones.

Interspecific predatory relationships

Despite their speed and hunting prowess, cheetahs are largely outranked by other large predators in most of their range. Because they have evolved for short bursts of extreme speed at the expense of both power and the ability to climb trees, they cannot defend themselves against most of Africa's other predator species. They usually avoid fighting and will surrender a kill immediately to even a single hyena, rather than risk injury. Because cheetahs rely on their speed to obtain their meals, any injury that slows them down could essentially be life threatening.

A cheetah has a 50% chance of losing its kill to other predators. Cheetahs avoid competition by hunting at different times of the day and by eating immediately after the kill. Due to the reduction in habitat in Africa, Cheetahs in recent years have faced greater pressure from other native African predators as available range declines.[citation needed]

The cheetah's mortality is very high during the early weeks of its life; up to 90% of cheetah cubs are killed during this time by lions, leopards, hyenas, wild dogs, or even by eagles. Cheetah cubs often hide in thick brush for safety. Mother cheetahs will defend their young and are at times successful in driving predators away from their cubs. Coalitions of male cheetahs can also chase away other predators, depending on the coalition size and the size and number of the predator. Because of its speed, a healthy adult cheetah has few predators.

Relationship with humans

Economic importance

Cheetah fur was formerly regarded as a status symbol. Today, cheetahs have a growing economic importance for ecotourism and they are also found in zoos. Cheetahs are far less aggressive than other felids and can be tamed, so cubs are sometimes illegally sold as pets.

Cheetahs were formerly, and sometimes still are, hunted because many farmers believe that they eat livestock. When the species came under threat, numerous campaigns were launched to try to educate farmers and encourage them to conserve cheetahs. Recent evidence has shown that cheetahs will not attack and eat livestock if they can avoid doing so, as they prefer their wild prey. However, they have no problem with including farmland as part of their territory, leading to conflict.

Taming

Ancient Egyptians often kept cheetahs as pets, and also tamed and trained them for hunting. Cheetahs would be taken to hunting fields in low-sided carts or by horseback, hooded and blindfolded, and kept on leashes while dogs flushed out their prey. When the prey was near enough, the cheetahs would be released and their blindfolds removed. This tradition was passed on to the ancient Persians and brought to India, where the practice was continued by Indian princes into the twentieth century. Cheetahs continued to be associated with royalty and elegance, their use as pets spreading just as their hunting skills were. Other such princes and kings kept them as pets, including Genghis Khan and Charlemagne, who boasted of having kept cheetahs within their palace grounds. Akbar the Great, ruler of the Mughal Empire from 1556 to 1605, kept as many as 1000 cheetahs. As recently as the 1930s the Emperor of Ethiopia, Haile Selassie, was often photographed leading a cheetah by a leash.

Conservation status

Cheetah cubs have a high mortality rate due to genetic factors and predation by carnivores in competition with the cheetah, such as the lion and hyena. Recent inbreeding causes cheetahs to share very similar genetic profiles. This has led to poor sperm, birth defects, cramped teeth, curled tails, and bent limbs. Some biologists now believe that they are too inbred to flourish as a species.

Cheetahs are included on the International Union for Conservation of Nature (IUCN) list of vulnerable species (African subspecies threatened, Asiatic subspecies in critical situation) as well as on the US Endangered Species Act: threatened species - Appendix I of CITES (Convention on International Trade in Endangered Species). Approximately 12,400 cheetahs remain in the wild in twenty-five African countries; Namibia has the most, with about 2,500. Another fifty to sixty critically endangered Asiatic Cheetahs are thought to remain in Iran. There have been successful breeding programs, including the use of in vitro fertilisation, in zoos around the world.

Founded in Namibia in 1990, the Cheetah Conservation Fund's mission is to be an internationally recognized centre of excellence in research and education on cheetahs and their eco-systems, working with all stakeholders to achieve best practice in the conservation and management of the world's cheetahs. The CCF has also set stations throughout South Africa in order to keep the conservation effort going. The Cheetah Conservation Foundation, a South African based organisation, was set up in 1993 for cheetah protection.
