Deer (singular and plural) are the hoofed ruminant mammals forming the family Cervidae. The two main groups are the Cervinae, including the muntjac, the elk (wapiti), the fallow deer, and the chital; and the Capreolinae, including the reindeer (caribou), the roe deer, and the moose. Female reindeer, and male deer of all species except the Chinese water deer, grow and shed new antlers each year. In this they differ from permanently horned antelope, which are part of a different family (Bovidae) within the same order of even-toed ungulates (Artiodactyla).

The musk deer of Asia and chevrotains of tropical African and Asian forests are not usually regarded as true deer and form their own families: Moschidae and Tragulidae, respectively.

Deer appear in art from Paleolithic cave paintings onwards, and they have played a role in mythology, religion, and literature throughout history, as well as in heraldry. Their economic importance includes the use of their meat as venison, their skins as soft, strong buckskin, and their antlers as handles for knives. Deer hunting has been a popular activity since at least the Middle Ages and remains a resource for many families today.

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.

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. 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 niches of the ibex and 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, Iberian 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 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, 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.[1]


Life Histories of Northern Mammals (1909) Cervidae tails
Tails of I) white-tailed deer, II) mule deer, III) black-tailed deer, IV) elk, V) red deer

Deer constitute the second most diverse family of artiodactyla after bovids.[2] Though of a similar build, deer are strongly distinguished from antelopes by their antlers, which are temporary and regularly regrown unlike the permanent horns of bovids.[3] Characteristics typical of deer include long, powerful legs, a diminutive tail and long ears.[4] Deer exhibit a broad variation in physical proportions. The largest extant deer is the moose, which is nearly 2.6 metres (8.5 ft) tall and weighs up to 800 kilograms (1,800 lb).[5][6] The elk stands 1.4–2 metres (4.6–6.6 ft) at the shoulder and weighs 240–450 kilograms (530–990 lb).[7] On the contrary, the northern pudu is the smallest deer in the world; it reaches merely 32–35 centimetres (13–14 in) at the shoulder and weighs 3.3–6 kilograms (7.3–13.2 lb). The southern pudu is only slightly taller and heavier.[8] Sexual dimorphism is quite pronounced – in most species males tend to be larger than females,[9] and, except for the reindeer, only males possess antlers.[10]

Coat colour generally varies between red and brown,[11] though it can be as dark as chocolate brown in the tufted deer[12] or have a grayish tinge as in elk.[7] Different species of brocket deer vary from gray to reddish brown in coat colour.[13] Several species such as the chital,[14] the fallow deer[15] and the sika deer[16] feature white spots on a brown coat. Coat of reindeer shows notable geographical variation.[17] Deer undergo two moults in a year;[11][18] for instance, in red deer the red, thin-haired summer coat is gradually replaced by the dense, greyish brown winter coat in autumn, which in turn gives way to the summer coat in the following spring.[19] Moulting is affected by the photoperiod.[20]

Deer are also excellent jumpers and swimmers. Deer are ruminants, or cud-chewers, and have a four-chambered stomach. Some deer, such as those on the island of Rùm,[21] do consume meat when it is available.[22]

A fawn's first steps

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.


All male deer possess antlers, with the exception of the water deer, in which males have long tusk-like canines that reach below the lower jaw.[23] Females generally lack antlers, though female reindeer bear antlers smaller and less branched than those of the males.[24] Occasionally females in other species may develop antlers, especially in telemetacarpal deer such as European roe deer, red deer, white-tailed deer and mule deer and less often in plesiometacarpal deer. A study of antlered female white-tailed deer noted that antlers tend to be small and malformed, and are shed frequently around the time of parturition.[25]

The fallow deer and the various subspecies of the reindeer have the largest as well as the heaviest antlers, both in absolute terms as well as in proportion to body mass (an average of 8 grams (0.28 oz) per kilogram of body mass);[24][26] the tufted deer, on the other hand, has the smallest antlers of all deer, while the pudú has the lightest antlers with respect to body mass (0.6 grams (0.021 oz) per kilogram of body mass).[24] The structure of antlers show considerable variation; while fallow deer and elk antlers are palmate (with a broad central portion), white-tailed deer antlers include a series of tines sprouting upward from a forward-curving main beam, and those of the pudú are mere spikes.[8] Antler development begins from the pedicel, a bony structure that appears on the top of the skull by the time the animal is a year old. The pedicel gives rise to a spiky antler the following year, that is replaced by a branched antler in the third year. This process of losing a set of antlers to develop a larger and more branched set continues for the rest of the life.[24] The antlers emerge as soft tissues (known as velvet antlers) and progressively harden into bony structures (known as hard antlers), following mineralisation and blockage of blood vessels in the tissue, from the tip to the base.[27]

Antlers might be one of the most exaggerated male secondary sexual characteristics,[28] and are intended primarily for reproductive success through sexual selection and for combat. The tines (forks) 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.[29] Antlers are correlated to an individual's position in the social hierarchy and its behaviour. For instance, the heavier the antlers, the higher the individual's status in the social hierarchy, and the greater the delay in shedding the antlers;[24] males with larger antlers tend to be more aggressive and dominant over others.[30] Antlers can be an honest signal of genetic quality; males with larger antlers relative to body size tend to have increased resistance to pathogens[31] and higher reproductive capacity.[32]

In elk in Yellowstone National Park, antlers also provide protection against predation by wolves.[33]


Most deer bear 32 teeth; the corresponding dental formula is: The elk and the reindeer may be exceptions, as they may retain their upper canines and thus have 34 teeth (dental formula:[34] 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.[35] 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.


Fawn in Forest edit


Deer are browsers, and feed primarily 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. The low-fibered food, after minimal fermentation and shredding, passes rapidly through the alimentary canal. The deer require a large amount of minerals such as calcium and phosphate in order to support antler growth, and this further necessitates a nutrient-rich diet. There are, however, some reports of deer engaging in carnivorous activity, such as depredating the nests of Northern bobwhites.[36]

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). Mating season typically begins in later August and lasts until December. Some species mate until early March. 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.[37] 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.


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,[38][39] a disease which in the UK in 2005 cost £90 million in attempts to eradicate.[40] 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.[41] 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.[42]

Moose and deer can carry rabies.[43]

Docile moose may suffer from brain worm, a helminth which drills holes through the brain in its search for a suitable place to lay its eggs. A government biologist states that "They move around looking for the right spot and never really find it." Deer appear to be immune to this parasite; it passes through the digestive system and is excreted in the feces. The parasite is not screened by the moose intestine, and passes into the brain where damage is done that is externally apparent, both in behaviour and in gait.[43]

Dear, elk and moose in North America may suffer from chronic wasting disease, which was identified at a Colorado laboratory in the 1960s and is believed to be a prion disease. Out of an abundance of caution hunters are advised to avoid contact with specified risk material (SRM) such as the brain, spinal column or lymph nodes. Deboning the meat when butchering and sanitizing the knives and other tools used to butcher are amongst other government recommendations.[44]


Deer are believed to have evolved from antlerless, tusked ancestors that resembled modern duikers and diminutive deer in the early Eocene, and gradually developed into the first antlered cervoids (the superfamily of cervids and related extinct families) in the Miocene. Eventually, with the development of antlers, the tusks as well as the upper incisors disappeared. Thus evolution of deer took nearly 30 million years. Biologist Valerius Geist suggests evolution to have occurred in stages. There are not many prominent fossils to trace this evolution, but only fragments of skeletons and antlers that might be easily confused with false antlers of non-cervid species.[8][45]

Eocene epoch

The ruminants, ancestors of the Cervidae, are believed to have evolved from Diacodexis, the earliest known artiodactyl (even-toed ungulate), 50–55 Mya in the Eocene.[46] Diacodexis, nearly the size of a rabbit, featured the talus bone characteristic of all modern even-toed ungulates. This ancestor and its relatives occurred throughout North America and Eurasia, but were on the decline by at least 46 Mya.[46][47] Analysis of a nearly complete skeleton of Diacodexis discovered in 1982 gave rise to speculation that this ancestor could be closer to the non-ruminants than the ruminants.[48] Andromeryx is another prominent prehistoric ruminant, but appears to be closer to the tragulids.[49]

Oligocene epoch

The formation of the Himalayas and the Alps brought about significant geographic changes. This was the chief reason behind the extensive diversification of deer-like forms and the emergence of cervids from the Oligocene to the early Pliocene.[50] The latter half of the Oligocene (28–34 Mya) saw the appearance of the European Eumeryx and the North American Leptomeryx. The latter resembled modern-day bovids and cervids in dental morphology (for instance, it had brachyodont molars), while the former was more advanced.[51] Other deer-like forms included the North American Blastomeryx and the European Dremotherium; these sabre-toothed animals are believed to have been the direct ancestors of all modern antlered deer, though they themselves lacked antlers.[52] Another contemporaneous form was the four-horned protoceratid Protoceras, that was replaced by Syndyoceras in the Miocene; these animals were unique in having a horn on the nose.[45] Late Eocene fossils dated approximately 35 million years ago, which were found in North America, show that Syndyoceras had bony skull outgrowths that resembled non-deciduous antlers.[53]

Miocene epoch

Fossil evidence suggests that the earliest members of the superfamily Cervoidea appeared in Eurasia in the Miocene. Dicrocerus, Euprox and Heteroprox were probably the first antlered cervids.[54] Dicrocerus featured single-forked antlers that were shed regularly.[55] Stephanocemas had more developed and diffuse ("crowned") antlers.[56] Procervulus (Palaeomerycidae), in addition to the tusks of Dremotherium, possessed antlers that were not shed.[57] Contemporary forms such as the merycodontines eventually gave rise to the modern pronghorn.[58]

The Cervinae emerged as the first group of extant cervids around 7–9 Mya, during the late Miocene in central Asia. The tribe Muntiacini made its appearance as Muntiacus leilaoensis around 7–8 Mya;[59] The early muntjacs varied in size–as small as hares or as large as fallow deer. They had tusks for fighting and antlers for defence.[8] Capreolinae followed soon after; Alceini appeared 6.4–8.4 Mya.[60] Around this period, the Tethys Ocean disappeared to give way to vast stretches of grassland; these provided the deer with abundant protein-rich vegetation that led to the development of ornamental antlers and allowed populations to flourish and colonise areas.[8][50] As antlers had become pronounced, the canines were no more retained or were poorly represented (as in elk), probably because diet was no more browse-dominated and antlers were better display organs. In muntjac and tufted deer, the antlers as well as the canines are small. The tragulids, however, possess long canines to this day.[47]

Pliocene epoch

With the onset of the Pliocene, the global climate became cooler. A fall in the sea-level led to massive glaciation; consequently, grasslands abounded in nutritious forage. Thus a new spurt in deer populations ensued.[8][50] The oldest member of Cervini, Cervocerus novorossiae, appeared around the transition from Miocene to Pliocene (4.2–6 Mya) in Eurasia;[61] cervine fossils from early Pliocene to as late as the Pleistocene have been excavated in China[62] and the Himalayas.[63] While Cervus and Dama appeared nearly 3 Mya, Axis emerged during the late Pliocene–Pleistocene. The tribes Capreolini and Rangiferini appeared around 4–7 Mya.[60]

Around 5 Mya, the rangiferines Bretzia and Eocoileus were the first cervids to reach North America.[60] This implies the Bering Strait could be crossed during the late Miocene–Pliocene; this appears highly probable as the camelids migrated into Asia from North America around the same time.[64] Deer invaded South America in the late Pliocene (2.5–3 Mya) as part of the Great American Interchange, thanks to the recently formed Isthmus of Panama, and emerged successful due to the small number of competing ruminants in the continent.[65]

Pleistocene epoch

Large deer with impressive antlers evolved during the early Pleistocene, probably as a result of abundant resources to drive evolution.[8] The early Pleistocene cervid Eucladoceros was comparable in size to the modern elk.[66] Megaloceros (Pliocene–Pleistocene) featured the Irish elk (M. giganteus), one of the largest known cervids. The Irish elk reached 2 metres (6.6 ft) at the shoulder and had heavy antlers that spanned 3.6 metres (12 ft) from tip to tip.[67] These large animals are thought to have faced extinction due to conflict between sexual selection for large antlers and body and natural selection for a smaller form.[68] Meanwhile, the moose and reindeer radiated into North America from Siberia.[69]

Taxonomy and classification

Cervid skull-FMVZ USP-21.jpeg
Cervid skull

Deer constitute the artiodactyl family Cervidae. This family was first described by German zoologist Georg August Goldfuss in Handbuch der Zoologie (1820). Three subfamilies are recognised: Capreolinae (first described by the English zoologist Joshua Brookes in 1828), Cervinae (described by Goldfuss) and Hydropotinae (first described by French zoologist Édouard Louis Trouessart in 1898).[2][70]

Other attempts at the classification of deer have been based on morphological and genetic differences.[45] The Anglo-Irish naturalist Victor Brooke suggested in 1878 that deer could be bifurcated into two classes on the according to the features of the second and fifth metacarpal bones of their forelimbs: Plesiometacarpalia (most Old World deer) and Telemetacarpalia (most New World deer). He treated the musk deer as a cervid, placing it under Telemetacarpalia. While the telemetacarpal deer showed only those elements located far from the joint, the plesiometacarpal deer retained the elements closer to the joint as well.[71] Differentiation on the basis of diploid number of chromosomes in the late 20th century has been flawed by several inconsistencies.[45]

In 1987, the zoologists Colin Groves and Peter Grubb identified three subfamilies: Cervinae, Hydropotinae and Odocoileinae; they noted that the hydropotines lack antlers, and the other two subfamilies differ in their skeletal morphology.[72] However, they reverted from this classification in 2000.[73]

External relationships

Until the beginning of the 21st century it was understood that the family Moschidae (musk deer) is sister to Cervidae. However, a 2003 phylogenetic study by Alexandre Hassanin (of National Museum of Natural History, France) and colleagues, based on mitochondrial and nuclear analyses, revealed that Moschidae and Bovidae form a clade sister to Cervidae. According to the study, Cervidae diverged from the Bovidae-Moschidae clade 27 to 28 million years ago.[74] A similar study in 2013 echoed the findings of this study.[75] The following cladogram is based on the 2003 study.[74]

Internal relationships

A 2006 phylogenetic study of the internal relationships in Cervidae by Clément Gilbert and colleagues divided the family into two major clades: Capreolinae (telemetacarpal or New World deer) and Cervinae (plesiometacarpal or Old World deer). Studies in the late 20th century suggested a similar bifurcation in the family. This as well as previous studies support monophyly in Cervinae, while Capreolinae appears paraphyletic. The 2006 study identified two lineages in Cervinae, Cervini (comprising the genera Axis, Cervus, Dama and Rucervus) and Muntiacini (Muntiacus and Elaphodus). Capreolinae featured three lineages, Alceini (Alces species), Capreolini (Capreolus and the subfamily Hydropotinae) and Rangiferini (Blastocerus, Hippocamelus, Mazama, Odocoileus, Pudu and Rangifer species). The following cladogram is based on the 2006 study.[60]

Extant subfamilies, genera and species

The subfamily Capreolinae consists of 9 genera and 36 species, while Cervinae comprises 10 genera and 55 species.[70] Hydropotinae consists of a single species, the water deer (H. inermis); however, a 1998 study placed it under Capreolinae.[76] The following list is based on molecular and phylogenetic studies by zoologists such as Groves and Grubb.[77][78][79][80][81]

In prehistory

Deer were an important source of food for early hominids. In China, Homo erectus fed upon the sika deer, while the red deer was hunted in Germany. In the Upper Palaeolithic, the reindeer was the staple food for Cro-Magnon people,[93] while the cave paintings at Lascaux in southwestern France include some 90 images of stags.[94]

In history

Deer had a central role in the ancient art, culture and mythology of the Hittites, the ancient Egyptians, the Celts, the ancient Greeks, the Asians and several others. For instance, the Stag Hunt Mosaic of ancient Pella, under the Kingdom of Macedonia (4th century BC), possibly depicts Alexander the Great hunting a deer with Hephaistion.[95] In Japanese Shintoism, the sika deer is believed to be a messenger to the gods. In China, deer are associated with great medicinal significance; deer penis is thought by some in China to have aphrodisiac properties.[96] Spotted deer are believed in China to accompany the god of longevity. Deer was the principal sacrificial animal for the Huichal Indians of Mexico. In medieval Europe, deer appeared in hunting scenes and coats-of-arms. Deer are depicted in many materials by various pre-Hispanic civilizations in the Andes.[93][97]

The common male first name Oscar is taken from the Irish Language, where it is derived from two elements: the first, os, means "deer"; the second element, cara, means "friend". The name is borne by a famous hero of Irish mythologyOscar, grandson of Fionn Mac Cumhail. The name was popularised in the 18th century by James Macpherson, creator of 'Ossianic poetry'.

In literature

Deer have been an integral part of fables and other literary works since the inception of writing. Stags were used as symbols in the latter Sumerian writings. For instance, the boat of Sumerian god Enki is named the Stag of Azbu. There are several mentions of the animal in the Rigveda as well as the Bible. In the Indian epic Ramayana, Sita is lured by a golden deer which Rama tries to catch. In the absence of both Rama and Lakshman, Ravana kidnaps Sita. Many of the allegorical Aesop's fables, such as "The Stag at the Pool", "The One-Eyed Doe" and "The Stag and a Lion", personify deer to give moral lessons. For instance, "The Sick Stag" gives the message that uncaring friends can do more harm than good.[93] 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 would perform at religious and social functions many times of the year, especially during Lent and Easter.[93][98]

In one of Rudolf Erich Raspe's 1785 stories of Baron Munchausen's Narrative of his Marvellous Travels and Campaigns in Russia, 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 Christmas lore (such as in the narrative poem "A Visit from St. Nicholas"), reindeer are often depicted pulling the sleigh of Santa Claus.[99] Marjorie Kinnan Rawlings's Pulitzer Prize-winning 1938 novel The Yearling was about a boy's relationship with a baby deer. The fiction book Fire Bringer is about a young fawn who goes on a quest to save the Herla, the deer kind.[100] In the 1942 Walt Disney Pictures film, Bambi is a white-tailed deer, while in Felix Salten's original 1923 book Bambi, a Life in the Woods, he is a roe deer. In C. S. Lewis's 1950 fantasy novel The Lion, the Witch and the Wardrobe 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 1979 book The Animals of Farthing Wood, The Great White Stag is the leader of all the animals.

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. A deer appears on the arms of the Israeli Postal Authority (see Hebrew language Wikipedia page).[101] Coats of arms featuring deer include those of Dotternhausen, Thierachern, Friolzheim, Bauen, Albstadt, and Dassel in Germany; of the Earls Bathurst in England; of Balakhna, Russia; of Åland, Finland; of Gjemnes, Hitra, Hjartdal, Rendalen and Voss in Norway; of Jelenia Góra, Poland; of Umeå, Sweden; of Cervera, Catalonia; of Northern Ireland; and of Chile.

Economic significance

Deer have long had economic significance to humans. Deer meat, known as venison, is highly nutritious and beneficial for human consumption. Due to the inherently wild nature and diet of deer, venison is most often obtained through deer hunting. In the United States, it is produced in small amounts compared to beef but still represents a significant trade. By 2012, some 25,000 tons of red deer were raised on farms in North America. The major deer-producing countries are New Zealand, the market leader, with Ireland, Great Britain and Germany. The trade earns over $100 million annually for these countries.[102]

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".[103] Among the Inuit, the traditional ulu women's knife was made with an antler, horn, or ivory handle.[104]

Deer have long been bred in captivity as ornaments for parks, but only in the case of reindeer has thorough domestication succeeded.[103] 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.[105] In North America, the reindeer, known there as caribou, is not domesticated or herded, but it is important as a quarry animal to the Caribou Inuit.[106]

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.[107] 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.[108]

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,[38][39] a disease which in the UK in 2005 cost £90 million in attempts to eradicate.[40] 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.[41] 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 killed approximately 489,922 white-tailed deer to procure venison, control the deer population, and minimize the spread of disease. 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.[42]

Deer hunting is a popular activity in the U.S. that provides the hunter's family with high quality meat 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.[109]


The word deer was originally broad in meaning, becoming more specific with time. Old English dēor and Middle English der meant a wild animal of any kind. 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.[110] This general sense gave way to the modern English sense by the end of the Middle English period, around 1500. However, all modern Germanic languages save English and Scots retain the more general sense: for example, German Tier and Norwegian dyr mean animal.[111]


For many types of deer in modern English usage, the male is a buck and the female a doe, but the terms vary with dialect, and according to the size of the species. The male red deer is a stag, while for other large species the male is a bull, the female a cow, as in cattle. In older usage, the male of any species is a hart, especially if over five years old, and the female is a hind, especially if three or more years old.[112] The young of small species is a fawn and of large species a calf; a very small young may be a kid. A castrated male is a havier.[113] A group of any species is a herd. The adjective of relation is cervine; like the family name Cervidae, this is from Latin: cervus, meaning stag or deer.

Andrew Wakefield

Andrew Jeremy Wakefield (born 1957) is a discredited former British doctor who became an anti-vaccine activist. He was a gastroenterologist until he was struck off the UK medical register for unethical behaviour, misconduct and dishonesty. In 1998 he was the lead author of a fraudulent research paper claiming that there was a link between the measles, mumps and rubella (MMR) vaccine and autism and bowel disease.After the publication of the paper, other researchers were unable to reproduce Wakefield's findings or confirm his hypothesis of an association between the MMR vaccine and autism, or autism and gastrointestinal disease. A 2004 investigation by Sunday Times reporter Brian Deer identified undisclosed financial conflicts of interest on Wakefield's part, and most of his co-authors then withdrew their support for the study's interpretations. The British General Medical Council (GMC) conducted an inquiry into allegations of misconduct against Wakefield and two former colleagues. The investigation centred on Deer's numerous findings, including that children with autism were subjected to unnecessary invasive medical procedures such as colonoscopies and lumbar punctures, and that Wakefield acted without the required ethical approval from an institutional review board.

On 28 January 2010, a five-member statutory tribunal of the GMC found three dozen charges proved, including four counts of dishonesty and 12 counts involving the abuse of developmentally delayed children. The panel ruled that Wakefield had "failed in his duties as a responsible consultant", acted both against the interests of his patients, and "dishonestly and irresponsibly" in his published research. The Lancet fully retracted the 1998 publication on the basis of the GMC's findings, noting that elements of the manuscript had been falsified. The Lancet's editor-in-chief Richard Horton said the paper was "utterly false" and that the journal had been "deceived". Three months following The Lancet's retraction, Wakefield was struck off the UK medical register, with a statement identifying deliberate falsification in the research published in The Lancet, and was thereby barred from practising medicine in the UK.In January 2011, an editorial accompanying an article by Brian Deer in BMJ described Wakefield's work as an "elaborate fraud". In a follow-up article, Deer said that Wakefield had planned to launch a venture on the back of an MMR vaccination scare that would profit from new medical tests and "litigation driven testing". In November 2011, another report in BMJ revealed original raw data indicating that, contrary to Wakefield's claims in The Lancet, children in his research did not have inflammatory bowel disease.Wakefield's study and his claim that the MMR vaccine might cause autism led to a decline in vaccination rates in the United States, United Kingdom and Ireland and a corresponding rise in measles and mumps, resulting in serious illness and deaths, and his continued claims that the vaccine is harmful have contributed to a climate of distrust of all vaccines and the reemergence of other previously controlled diseases. Wakefield has continued to defend his research and conclusions, saying there was no fraud, hoax or profit motive. In February 2015, he publicly repeated his denials and refused to back down from his assertions, even though—as stated by a British Administrative Court Justice in a related decision—"There is now no respectable body of opinion which supports (Dr. Wakefield's) hypothesis, that MMR vaccine and autism/enterocolitis are causally linked".


The biological subfamily Bovinae includes a diverse group of 10 genera of medium to large-sized ungulates, including domestic cattle, bison, African buffalo, the water buffalo, the yak, and the four-horned and spiral-horned antelopes. The evolutionary relationship between the members of the group is still debated, and their classification into loose tribes rather than formal subgroups reflects this uncertainty. General characteristics include cloven hooves and usually at least one of the sexes of a species having true horns. The largest extant bovine is the gaur.

In many countries, bovid milk and meat is used as food. Cattle are kept as livestock almost everywhere except in parts of India and Nepal where they are considered sacred by most Hindus. Bovids are used as draft animals and as riding animals. Small breeds of bovid, such as the Miniature Zebu, are kept as pets.


Chevrotains, also known as mouse-deer, are small ungulates that make up the family Tragulidae, the only members of the infraorder Tragulina. The 10 extant species are placed in three genera, but several species also are known only from fossils. The extant species are found in forests in South and Southeast Asia, with a single species in the rainforests of Central and West Africa. They are solitary or live in pairs, and feed almost exclusively on plant material. Chevrotains are the smallest hoofed mammals in the world. The Asian species weigh between 0.7 and 8.0 kg (1.5 and 17.6 lb), while the African chevrotain is considerably larger at 7–16 kg (15–35 lb).


The chital () or cheetal (Axis axis), also known as spotted deer or axis deer, is a species of deer that is native in the Indian subcontinent. The species was first described by German naturalist Johann Christian Polycarp Erxleben in 1777. A moderate-sized deer, male chital reach nearly 90 cm (35 in) and females 70 cm (28 in) at the shoulder. While males weigh 30–75 kg (66–165 lb), the lighter females weigh 25–45 kg (55–99 lb). The species is sexually dimorphic; males are larger than females, and antlers are present only on males. The upper parts are golden to rufous, completely covered in white spots. The abdomen, rump, throat, insides of legs, ears, and tail are all white. The antlers, three-pronged, are nearly 1 m (3.3 ft) long.


The elk or wapiti (Cervus canadensis) is one of the largest species within the deer family, Cervidae, in the world, and one of the largest terrestrial mammals in North America and Northeast Asia. This animal should not be confused with the still larger moose (Alces alces) to which the name "elk" applies in British English and in reference to populations in Eurasia.

Elk range in forest and forest-edge habitat, feeding on grasses, plants, leaves, and bark. Male elk have large antlers which are shed each year. Males also engage in ritualized mating behaviors during the rut, including posturing, antler wrestling (sparring), and bugling, a loud series of vocalizations that establishes dominance over other males and attracts females.

Although they are native to North America and eastern Asia, they have adapted well to countries in which they have been introduced, including Argentina and New Zealand. Their great adaptability may threaten endemic species and ecosystems into which they have been introduced.

Elk are susceptible to a number of infectious diseases, some of which can be transmitted to livestock. Efforts to eliminate infectious diseases from elk populations, largely by vaccination, have had mixed success.

Some cultures revere the elk as a spiritual force. In parts of Asia, antlers and their velvet are used in traditional medicines. Elk are hunted as a game species. The meat is leaner and higher in protein than beef or chicken.Elk were long believed to belong to a subspecies of the European red deer (Cervus elaphus), but evidence from many mitochondrial DNA genetic studies beginning in 1998 shows that the two are distinct species. Key morphological differences that distinguish C. canadensis from C. elaphus are the former's wider rump patch and paler-hued antlers.

Even-toed ungulate

The even-toed ungulates (Artiodactyla, from Ancient Greek ἄρτιος (ártios), meaning 'even', and δάκτυλος (dáktylos), meaning 'finger/toe') are ungulates - hoofed animals - which bear weight equally on two (an even number) of the five toes: their third and fourth toes. The other three toes are either present, absent, vestigial, or pointing posteriorly. By contrast, odd-toed ungulates bear weight on one (an odd number) of the five toes: the third toe. Another difference between the two is that even-toed ungulates digest plant cellulose in one or more stomach chambers rather than in their intestine as the odd-toed ungulates do.

The aquatic cetaceans (whales, dolphins, and porpoises) evolved from even-toed ungulates, so modern taxonomic classification sometimes combines the Artiodactyla and Cetacea into the Cetartiodactyla.

The roughly 220 land-based even-toed ungulate species include pigs, peccaries, hippopotamuses, camels, llamas, alpacas, mouse deer, deer, giraffes, antelopes, sheep, goats, and cattle. Many of these are of great dietary, economic, and cultural importance to humans.

Fallow deer

The fallow deer (Dama dama) is a ruminant mammal belonging to the family Cervidae. This common species is native to Europe, but has been introduced to Antigua & Barbuda, Argentina, South Africa, Fernando Pó, São Tomé, Madagascar, Mauritius, Mayotte, Réunion, Seychelles, Comoro Islands, Morocco, Algeria, Tunisia, Cyprus, Israel, Cape Verde, Lebanon, Australia, New Zealand, Canada, the United States, the Falkland Islands, and Peru. Some taxonomers include the rarer Persian fallow deer as a subspecies (D. d. mesopotamica), while others treat it as an entirely different species (D. mesopotamica).


The moose (North America) or elk (Eurasia), Alces alces is a member of the New World deer subfamily and is the largest and heaviest extant species in the Deer family. Moose are distinguished by the broad, palmate (open-hand shaped) antlers of the males; other members of the deer family have antlers with a dendritic ("twig-like") configuration. Moose typically inhabit boreal forests and temperate broadleaf and mixed forests of the Northern Hemisphere in temperate to subarctic climates. Hunting and other human activities have caused a reduction in the size of the moose's range over time. Moose have been reintroduced to some of their former habitats. Currently, most moose are found in Canada, Alaska, New England (with Maine having the most of the lower 48 states), Fennoscandia, Baltic states, and Russia. Their diet consists of both terrestrial and aquatic vegetation. The most common moose predators are the gray wolf along with bears and humans. Unlike most other deer species, moose do not form herds and are solitary animals, aside from calves who remain with their mother until the cow begins estrus (typically at 18 months after birth of the calf), at which point the cow chases away young bulls. Although generally slow-moving and sedentary, moose can become aggressive and move quickly if angered or startled. Their mating season in the autumn features energetic fights between males competing for a female.

Mule deer

The mule deer (Odocoileus hemionus) is a deer indigenous to western North America; it is named for its ears, which are large like those of the mule. The several subspecies include the black-tailed deer.Unlike the related white-tailed deer (Odocoileus virginianus), which is found through most of North America east of the Rockies Mountains and in the valleys of the Rocky Mountains from Idaho and Wyoming northward, mule deer are only found on the western Great Plains, in the Rocky Mountains, in the United States southwest, and on the West Coast of North America. Mule deer have also been introduced to Argentina and Kauai, Hawaii.


Muntjacs, also known as barking deer and Mastreani deer, are small deer of the genus Muntiacus native to south Asia. Muntjacs are thought to have begun appearing 15–35 million years ago, with remains found in Miocene deposits in France, Germany and Poland. It is listed as Least Concern by the IUCN.

Musk deer

Musk deer (Sanskrit: कस्तूरी मृग, and Hindi: कस्तूरी हिरन) can refer to any one, or all seven, of the species that make up Moschus, the only extant genus of the family Moschidae. The musk deer family differs from cervids, or true deer, by lacking antlers and facial glands and by possessing only a single pair of teats, a gallbladder, a caudal gland, a pair of tusk-like teeth and—of particular economic importance to humans—a musk gland.

Musk deer live mainly in forested and alpine scrub habitats in the mountains of southern Asia, notably the Himalayas. Moschids, the proper term when referring to this type of deer rather than one/multiple species of musk deer, are entirely Asian in their present distribution, being extinct in Europe where the earliest musk deer are known to have existed from Oligocene deposits.


A pig is any of the animals in the genus Sus, within the even-toed ungulate family Suidae. Pigs include the domestic pig and its ancestor, the common Eurasian wild boar (Sus scrofa), along with other species. Related creatures outside the genus include the peccary, the babirusa, and the warthog. Pigs, like all suids, are native to the Eurasian and African continents. Juvenile pigs are known as piglets. Pigs are highly social and intelligent animals.With around 1 billion individuals alive at any time, the domestic pig is among the most populous large mammals in the world. Pigs are omnivores and can consume a wide range of food. Biologically, pigs are very similar to humans, thus are frequently used for human medical research.

Red Deer, Alberta

Red Deer is a city in Central Alberta, Canada. It is located near the midpoint of the Calgary–Edmonton Corridor and is surrounded by Red Deer County. It is Alberta's third-most-populous city – after Calgary and Edmonton. The city is located in aspen parkland, a region of rolling hills that is home to oil, grain, and cattle production. It is a centre for oil and agriculture distribution, and the surrounding region is a major centre for petrochemical production. Red Deer had a population of 100,418 as of the Canada 2016 census making Red Deer Alberta's third city to surpass 100,000 people.

Red deer

The red deer (Cervus elaphus) is one of the largest deer species. The red deer inhabits most of Europe, the Caucasus Mountains region, Asia Minor, Iran, parts of western Asia, and central Asia. It also inhabits the Atlas Mountains region between Morocco and Tunisia in northwestern Africa, being the only species of deer to inhabit Africa. Red deer have been introduced to other areas, including Australia, New Zealand, United States, Canada, Peru, Uruguay, Chile and Argentina. In many parts of the world, the meat (venison) from red deer is used as a food source.

Red deer are ruminants, characterized by a four-chambered stomach. Genetic evidence indicates the red deer as traditionally defined is a species group, rather than a single species, although it remains disputed as to exactly how many species the group includes. The closely related and slightly larger American elk or wapiti, native to North America and eastern parts of Asia, had been regarded as a subspecies of red deer, but recently it has been established as a distinct species. It is probable that the ancestor of all red deer, including wapiti, originated in central Asia and resembled sika deer.Although at one time red deer were rare in parts of Europe, they were never close to extinction. Reintroduction and conservation efforts, such as in the United Kingdom and Portugal, have resulted in an increase of red deer populations, while other areas, such as North Africa, have continued to show a population decline.

Roe deer

The European roe deer (Capreolus capreolus), also known as the western roe deer, chevreuil, or simply roe deer or roe, is a species of deer. The male of the species is sometimes referred to as a roebuck. The roe deer is relatively small, reddish and grey-brown, and well-adapted to cold environments. The species is widespread in Europe, from the Mediterranean to Scandinavia, from Ireland to the Caucasus, and east to northern Iran and Iraq. It is distinct from the somewhat larger Siberian roe deer.

Sambar deer

The sambar (Rusa unicolor) is a large deer native to the Indian subcontinent, southern China, and Southeast Asia that is listed as Vulnerable on the IUCN Red List since 2008. Populations have declined substantially due to severe hunting, insurgency, and industrial exploitation of habitat.The name "sambar" is also sometimes used to refer to the Philippine deer, called the "Philippine sambar" and the Javan rusa, called the "Sunda sambar".

Sika deer

The sika deer (Cervus nippon) also known as the spotted deer or the Japanese deer, is a species of deer native to much of East Asia, and introduced to various other parts of the world. Previously found from northern Vietnam in the south to the Russian Far East in the north, it is now uncommon in these areas, excluding Japan, where the species is overabundant.

The Deer Hunter

The Deer Hunter is a 1978 American epic war drama film co-written and directed by Michael Cimino about a trio of Russian American steelworkers whose lives were changed forever after they fought in the Vietnam War. The three soldiers are played by Robert De Niro, Christopher Walken, and John Savage, with John Cazale (in his final role), Meryl Streep, and George Dzundza playing supporting roles. The story takes place in Clairton, Pennsylvania, a small working class town on the Monongahela River south of Pittsburgh, and in Vietnam.

The film was based in part on an unproduced screenplay called The Man Who Came to Play by Louis Garfinkle and Quinn K. Redeker, about Las Vegas and Russian roulette. Producer Michael Deeley, who bought the script, hired writer/director Michael Cimino who, with Deric Washburn, rewrote the script, taking the Russian roulette element and placing it in the Vietnam War. The film went over-budget and over-schedule, and ended up costing $15 million. The scenes depicting Russian roulette were highly controversial after the film's release.

The film won five Academy Awards, including Best Picture, Best Director for Michael Cimino, and Best Supporting Actor for Christopher Walken, and marked Meryl Streep's first Academy Award nomination (for Best Supporting Actress); she would go on to become the most nominated actor in history. In 1996 it was selected for preservation in the United States National Film Registry by the Library of Congress as being "culturally, historically, or aesthetically significant", and was named the 53rd greatest American film of all time by the American Film Institute in 2007 in their 10th Anniversary Edition of the AFI's 100 Years...100 Movies list.

White-tailed deer

The white-tailed deer (Odocoileus virginianus), also known as the whitetail or Virginia deer, is a medium-sized deer native to the United States, Canada, Mexico, Central America, and South America as far south as Peru and Bolivia. It has also been introduced to New Zealand, Cuba, Jamaica, Hispaniola, Puerto Rico, the Bahamas, the Lesser Antilles, and some countries in Europe, such as Finland, the Czech Republic, Romania and Serbia. In the Americas, it is the most widely distributed wild ungulate.

In North America, the species is widely distributed east of the Rocky Mountains as well as in most of Mexico, aside from Lower California, and in southwestern Arizona. In the Rocky Mountains and west of the Rocky Mountains, it is mostly replaced by the black-tailed or mule deer (Odocoileus hemionus), although it is found in mixed deciduous riparian corridors, river valley bottomlands, and lower foothills of the northern Rocky Mountain region from South Dakota west to eastern Washington and eastern Oregon and north to northeastern British Columbia and southern Yukon, including in the Montana Valley and Foothill grasslands.

The conversion of land adjacent to the Canadian Rockies into agriculture use and partial clear-cutting of coniferous trees (resulting in widespread deciduous vegetation) has been favorable to the white-tailed deer and has pushed its distribution to as far north as Yukon. Populations of deer around the Great Lakes have also expanded their range northwards, due to conversion of land to agricultural uses favoring more deciduous vegetation, and local caribou and moose populations. The westernmost population of the species, known as the Columbian white-tailed deer, once was widespread in the mixed forests along the Willamette and Cowlitz River valleys of western Oregon and southwestern Washington, but today its numbers have been considerably reduced, and it is classified as near-threatened. This population is separated from other white-tailed deer populations.
