Cervidae  

Deer (singular and plural) are the ruminant mammals forming the family Cervidae. Species in the family include white-tailed deer, mule deer such as black-tailed deer, elk, moose, red deer, reindeer (caribou), fallow deer, roe deer, pudú and chital. Male deer of all species (except 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, which 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[edit]

The word "deer" was originally broader in meaning, but became more specific over time. In Middle English, der (Old English dēor) meant a wild animal of any kind. This was as opposed to cattle, which then meant any sort of domestic livestock that was easy to collect and remove from the land, from the idea of personal-property ownership (rather than real estate property) and related to modern chattel (property) and capital.^[1] Cognates of Old English dēor in other dead Germanic languages have the general sense of "animal", such as Old High German tior, Old Norse djur or dȳr, Gothic dius, Old Saxon dier, and Old Frisian diar.

This general sense gave way to the modern English sense by the end of the Middle English period, around 1500.^[2] However, all modern Germanic languages save English and Scots retain the more general sense: for example, German Tier, Alemannic Diere or Tiere, Pennsylvania Dutch Gedier, Dutch dier, Afrikaans dier, Limburgish diere, Norwegian dyr, Swedish djur, Danish dyr, Icelandic dýr, Faroese dýr, West Frisian dier, and North Frisian diarten, all of which mean "animal". (However, contrary to south European languages, Dama in Latin and daim in French mean "fallow deer" only).

For most types of deer in modern English usage, the male is called a "buck" and the female is termed a "doe", but the terms vary with dialect, and especially according to the size of the species. For many larger deer, the male is termed a "stag", while for other larger deer the same words are used as for cattle: "bull" and "cow". The male red deer is a "hart", especially if more than five years old, and the female is a "hind", especially if three or more years old; both terms can also be used for any species of deer, and were widely so used in the past.^[3] Terms for young deer vary similarly, with that of most smaller species being called a "fawn" and that of most larger species "calf"; young of the smallest kinds may be a kid. A castrated male deer is a "havier".^[4] 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".

Venison originally described meat of any game animal killed by hunting,^[5] and was applied to any animal from the families Cervidae (deer), Leporidae (hares), and Suidae (wild pigs), and certain species of the genus Capra (goats and ibex). In the northern hemisphere, the usage of this term is now almost entirely restricted to the flesh of various species of deer.^{[citation needed]}

In Southern Africa, venison is used to refer to the meat of antelope.^[6] There are no native Cervidae in sub-Saharan Africa.

Deer are widely distributed, with indigenous representatives in all continents except Antarctica and Australia, though Africa has only one native deer, the Barbary stag, a subspecies of red deer that is confined to the Atlas Mountains in the northwest of the continent. However, fallow deer have been introduced to South Africa.

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 the 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, the wetlands between Austria, Hungary, and the Czech Republic and some fine National Parks, including 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 other herbivores, such as Asian elephants, the 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). One way that different herbivores can survive together in a given area is for each species to 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 the fallow deer, red deer, sambar, hog deer, rusa, 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.^[7]

Deer weights generally range from 30 to 300 kg (70 to 700 lb). The smallest species, the northern pudú, averages 10 kg (20 lb) and the largest, the moose, averages 431 kg (1,000 lb). 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,^[8] do consume meat when it is available.^[9]

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.^[10] The dental formula for deer is: 0.0-1.3.33.1.3.3

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.

Female elk nursing young

Nearly all cervids are so-called uniparental species: the fawns are only cared for by the mother, known as a doe. 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 to graze, and the fawn does not like to be left behind. Sometimes its mother must gently push it down with her foot.^[11] 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 leaves and 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 eating and digesting 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.

Reproduction[edit]

This section requires expansion. (November 2013)

Antlers[edit]

With the exception of the Chinese water deer, which have tusks, all male deer have antlers. Sometimes a female has 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 deer rubs off the velvet, 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". The deer rub trees 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. The tines on the antlers create grooves that allow another male's antlers to lock into place. This allows the males to wrestle without risking injury to the face.^[12]

Antlers can be a sign of genetic quality. Males with larger antlers relative to body size tend to have increased resistance to pathogens ^[13] and higher reproductive capacity.^[14] Necropsy research on wild deer that were killed and eaten by wolves shows that deer with asymmetric antlers are weakened by genetic defects and are less likely to escape being caught by predators.^{[citation needed]}

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, have bifurcated (or branched) antlers—that is, the main beam splits into two, each of which may split into two more.^[15] Young males of many deer, and the adults of some species, such as brocket deer and pudus, have antlers that are single spikes.

Piebald deer[edit]

Piebald doe

A piebald deer is a deer with a brown and white spotting pattern that 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[edit]

Seneca County, New York maintains the largest herd of white deer. White pigmented white-tailed deer began populating the deer population in what is 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.

White tail fawns are born a brown or tan color with a spotted white pattern. Sometimes these fawns can be born with a grey appearance, making them seem dirty. The coats become pure white in the middle of their second year, and they are sometimes mistaken for albino deer.

Albino whitetail deer appear to have pink skin with a pure white coat, and the irises of their eyes are usually pink as well. There is no such thing as a partial albino; true albino deer have little or no melanin in their bodies. Their color is mainly white because it lacks any pigments, making the skin appear pink because the flowing blood can be seen through the skin. Their white coats make them especially vulnerable to predators. ^[17]

Evolution[edit]

The earliest fossil deer date from the Oligocene of Europe,^{[citation needed]} and resembled the modern muntjacs. Later species were often larger, with more impressive antlers, and, in many cases, no upper canine teeth. They rapidly spread to the other continents. For a time they occupied much of northern Africa, but are now almost wholly absent from that continent. 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.

Syndyocera was one of the first animals considered to be related to the deer, sharing similar features common with the deer, horse, giraffe, and antelope. Fossils dated approximately 35 million years ago, which were found in North America, show it had bony skull outgrowths that resembled non-deciduous antlers. Another animal also thought to be related to the deer is the world's oldest known antler-shedding deer, Dicrocerus elegans. This animal's sediment deposits are found in European soil dating back to between 15–30 million years ago.^[18] Yet another distant ancestor is thought to be Archaeomeryx.^{[citation needed]}

Taxonomy[edit]

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 today 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[edit]

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. 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 Père David deer in order to create a farmed deer that 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 that 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 four 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.^{[citation needed]} Hybrids do survive on game ranches where both species are kept and where predators are controlled by man.

Cultural significance[edit]

Heraldry[edit]

Wikimedia Commons has media related to Deer in 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 that appears on the ancient arms. Examples of deer in coats of arms can be found in the arms of Hertfordshire, England, and its county town of Hertford; both are examples of canting arms, and also in the coat of arms of Northern Ireland.

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 language Wikipedia page).^[22]

• 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.
• 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.
• Deer have been a subject in Chinese paintings numerous times as a tranquility symbol.
• The Yaqui deer song 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 considered messengers to the gods in Japan. Deer dance has been traditionally performed in various parts of Japan, especially in Northeastern areas, as a ritual.^[23]
• Deer are depicted in many materials by various pre-Hispanic civilizations in the Andes.^[24]
• 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.
• In The Lion, the Witch and the Wardrobe, the first published 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.
• 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.
• A picture of a stag was used as part of the logo design for the House of Fraser department store until 2006.
• In the Song of Ice and Fire book series and its TV adaptation, Game of Thrones, a crowned stag is the coat of arms of House Baratheon.

Economic significance[edit]

"The Stag Hunt of Frederick III, Elector of Saxony" by Lucas Cranach the Elder

Nicholas Mavrogenes, Phanariote Prince of Wallachia, riding through Bucharest in a deer−drawn carriage (late 1780s)

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 skins make a peculiarly strong, soft leather, known as buckskin. There is nothing special about skins with the fur on since the hair is brittle and soon falls off. The hoofs and horns are used for ornamental purposes, especially the antlers of the roe deer, which are utilized for making umbrella handles, and for similar purposes; elk horn is often employed in making knife handles. In China, a medicine is made from stag horn, and the antlers of certain species are eaten when "in the velvet".^[25]

Deer have long been bred in captivity as ornaments for parks, but only in the case of reindeer has thorough domestication succeeded.^[25] The Sami of Scandinavia and the Kola Peninsula of Russia and other nomadic peoples of northern Asia use reindeer for food, clothing, and transport. Deer bred for hunting are selected based on the size of the antlers.^[26]

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.^[27] In Scotland, several roads including the A82, the A87 and the A835 have had significant enough problems with deer vehicle collisions (DVCs) that sets of vehicle activated automatic warning signs have been installed along these roads.^[28]

The sight of deer standing motionless, caught in headlights gives rise to the phrase "deer in the headlights".

In some areas of the UK, deer (especially fallow deer due to their gregarious behaviour), have been implicated as a possible reservoir for transmission of bovine tuberculosis,^[29][30] a disease which in the UK in 2005 cost £90 million in attempts to eradicate.^[31] In New Zealand, deer are thought to be important as vectors picking up M. bovis in areas where brushtail possums, (Trichosurus vulpecula), are infected, and transferring it to previously uninfected possums when their carcasses are scavenged elsewhere.^[32] The white-tailed deer, (Odocoileus virginianus), has been confirmed as the sole maintenance host in the Michigan outbreak of bovine tuberculosis which remains a significant barrier to the US nationwide eradication of the disease in livestock. In 2008, 733,998 licensed deer hunters harvested approximately 489,922 white-tailed deer in attempts to control the deer population and disease spread. These hunters purchased more than 1.5 million deer harvest tags. The economic value of deer hunting to Michigan’s economy is substantial. For example, in 2006, hunters spent US$507 million hunting white-tailed deer in Michigan.^[33]

Deer hunting is a popular activity in the U.S. and generates revenue for states and the federal government from the sales of licenses, permits and tags. The 2006 survey by the U.S. Fish and Wildlife Service estimates that license sales generate approximately $700 million annually. This revenue generally goes to support conservation efforts in the states where the licenses are purchased. Overall, the U.S. Fish and Wildlife Service estimates that big game hunting for deer and elk generates approximately $11.8 billion annually in hunting-related travel, equipment and related expenditures.^[34]
