White-tailed deer

Odocoileus virginianus

The white-tailed deer , 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, but elsewhere, it is mostly replaced by the black-tailed or mule deer . In western North America, it is found in aspen parklands and deciduous river bottomlands within the central and northern Great Plains, and in mixed deciduous riparian corridors, river valley bottomlands, and lower foothills of the northern Rocky Mountain regions from South Dakota and Wyoming to northeastern British Columbia, including the Montana Valley and Foothill grasslands.

The conversion of land adjacent to the northern Rockies into agriculture use and partial clear-cutting of coniferous trees has been favorable to the white-tailed deer and has pushed its distribution to as far north as Fort St. John, British Columbia. 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.

The deer's coat is a reddish-brown in the spring and summer and turns to a grey-brown throughout the fall and winter. The deer can be recognized by the characteristic white underside to its tail. It raises its tail when it is alarmed to warn the predator that it has been detected. A population of white-tailed deer in New York is entirely white —not albino—in color. The former Seneca Army Depot in Romulus, New York, has the largest known concentration of white deer. An indication of a deer age is the length of the snout and the color of the coat, with older deer tending to have longer snouts and grayer coats. Strong conservation efforts have allowed white deer to thrive within the confines of the depot. White-tailed deer's horizontally slit pupils allow for good night vision and color vision during the day.

Surprise - Fawn White-tailed Deer - North Idaho This instance is the perfect example why I always carry my camera. I was checking some things at the river for work today when I paused to soak in the scenery and listen to the rushing water. 

As I was taking in the sights and sounds, I noticed something moving quickly out of the corner of my eye. I turned to see this fawn running down the path I had just made in the snow. She came to a skidding halt about 10 meters from me, in this exact position. She did not move for ten seconds as she stared at me.

Eventually she decided that it was not worth her time to proceed any further, and ran back off in the direction she came. Luckily I had my camera, and a quick response! Geotagged,Idaho,Mammals,Odocoileus virginianus,Snow,United States,White-tailed Deer,Winter,winter


Several methods have been developed in attempts to curb the population of white-tailed deer, and these can be separated into lethal and nonlethal strategies. Most common in the U.S is the use of extended hunting as population control. In Maryland and many other states, a state agency sets regulations on bag limits and hunting in the area depending on the deer population levels assessed. Hunting seasons may fluctuate in duration, or restrictions may be set to affect how many deer or what type of deer can be hunted in certain regions. For the 2015–2016 white-tailed deer-hunting season, some areas only allow for the hunting of antlerless white-tailed deer. These would include young bucks and females, encouraging the culling of does which would otherwise contribute to increasing populations via offspring production.

More refined than public hunting is a method referred to as sharpshooting by the Deer Task Force in the city of Bloomington, Indiana. Sharpshooting can be an option when the area inhabited by the deer is unfit for public hunting. This strategy may work in areas close to human populations, since it is done by professional marksmen, and requires a submitted plan of action to the city with details on the time and location of the event, as well as number of deer to be culled.

Another controversial method involves trapping the deer in a net or other trap, and then administering a chemical euthanizing agent or extermination by firearm. A main issue in questioning the humaneness of this method is the stress that the deer endure while trapped and awaiting extermination.

Nonlethal methods include contraceptive injections, sterilization, and translocation of deer. While lethal methods have municipal support as being the most effective in the short term, some opponents to this view suggest no significant impacts of deer extermination on the populations occur. Opponents of contraceptive methods point out that fertility control proves ineffective over time as populations in open-field systems move about. Concerns are voiced that the contraceptives have not been adequately researched for the effect they could have on humans who consume the treated venison. Fertility control also does nothing to affect the current population and the effects their grazing may be having on the forest plant make-up.

Translocation has been considered overly costly for the little benefit it provides. Deer experience high stress and are at high risk of dying in the process, putting into question its humaneness. Another concern in using this method is the possible spread of chronic wasting disease found in the deer family and the lack of research on its effect on human populations.

Males compete for the opportunity of breeding females. Sparring among males determines a dominance hierarchy. Bucks attempt to copulate with as many females as possible, losing physical condition, since they rarely eat or rest during the rut. The general geographical trend is for the rut to be shorter in duration at increased latitude. Many factors determine how intense the "rutting season" will be; air temperature is a major one. Any time the temperature rises above 40 °F , the males do much less traveling looking for females, else they will be subject to overheating or dehydrating. Another factor for the strength in rutting activity is competition. If numerous males are in a particular area, then they compete more for the females. If fewer males or more females are present, then the selection process will not need to be as competitive.White-tailed deer have many forms of communication involving sounds, scent, body language, and marking. In addition to the aforementioned blowing in the presence of danger, all white-tailed deer are capable of producing audible noises unique to each animal. Fawns release a high-pitched squeal, known as a bleat, to call out to their mothers. This bleat deepens as the fawn grows until it becomes the grunt of the mature deer, a guttural sound that attracts the attention of any other deer in the area. A doe makes maternal grunts when searching for her bedded fawns. Bucks also grunt, at a pitch lower than that of the doe; this grunt deepens as the buck matures. In addition to grunting, both does and bucks also snort, a sound that often signals an imminent threat. Mature bucks also produce a grunt-snort-wheeze pattern, unique to each animal, that asserts its dominance, aggression, and hostility. Another way white-tailed deer communicate is through the use of their white tail. When spooked, it will raise its tail to warn the other deer in the immediate area.

White-tailed deer are generalists and can adapt to a wide variety of habitats. The largest deer occur in the temperate regions of Canada and United States. The northern white-tailed deer , Dakota white-tailed deer , and northwest white-tailed deer are some of the largest animals, with large antlers. The smallest deer occur in the Florida Keys and in partially wooded lowlands in the neotropics.

Although most often thought of as forest animals depending on relatively small openings and edges, white-tailed deer can equally adapt themselves to life in more open prairie, savanna woodlands, and sage communities as in the Southwestern United States and northern Mexico. These savanna-adapted deer have relatively large antlers in proportion to their body size and large tails. Also, a noticeable difference exists in size between male and female deer of the savannas. The Texas white-tailed deer , of the prairies and oak savannas of Texas and parts of Mexico, are the largest savanna-adapted deer in the Southwest, with impressive antlers that might rival deer found in Canada and the northern United States. Populations of Arizona and Carmen Mountains white-tailed deer inhabit montane mixed oak and pine woodland communities. The Arizona and Carmen Mountains deer are smaller, but may also have impressive antlers, considering their size. The white-tailed deer of the Llanos region of Colombia and Venezuela have antler dimensions similar to the Arizona white-tailed deer.

In western regions of the United States and Canada, the white-tailed deer range overlaps with those of the mule deer. White-tail incursions in the Trans-Pecos region of Texas have resulted in some hybrids. In the extreme north of the range, their habitat is also used by moose in some areas. White-tailed deer may occur in areas that are also exploited by elk such as in mixed deciduous river valley bottomlands and formerly in the mixed deciduous forest of eastern United States. In places such as Glacier National Park in Montana and several national parks in the Columbian Mountains and Canadian Rocky Mountains, as well as in the Yukon Territory , white-tailed deer are shy and more reclusive than the coexisting mule deer, elk, and moose.

Central American white-tailed deer prefer tropical and subtropical dry broadleaf forests, seasonal mixed deciduous forests, savanna, and adjacent wetland habitats over dense tropical and subtropical moist broadleaf forests. South American subspecies of white-tailed deer live in two types of environments. The first type, similar to the Central American deer, consists of savannas, dry deciduous forests, and riparian corridors that cover much of Venezuela and eastern Colombia. The other type is the higher elevation mountain grassland/mixed forest ecozones in the Andes Mountains, from Venezuela to Peru. The Andean white-tailed deer seem to retain gray coats due to the colder weather at high altitudes, whereas the lowland savanna forms retain the reddish brown coats. South American white-tailed deer, like those in Central America, also generally avoid dense moist broadleaf forests.

Since the second half of the 19th century, white-tailed deer have been introduced to Europe. A population in the Brdy area remains stable today. In 1935, white-tailed deer were introduced to Finland. The introduction was successful, and the deer have recently begun spreading through northern Scandinavia and southern Karelia, competing with, and sometimes displacing, native species. The current population of some 30,000 deer originated from four animals provided by Finnish Americans from Minnesota.

Females enter estrus, colloquially called the rut, in the autumn, normally in late October or early November, triggered mainly by the declining photoperiod. Sexual maturation of females depends on population density, as well as availability of food. Young females often flee from an area heavily populated with males. Some does may be as young as six months when they reach sexual maturity, but the average age of maturity is 18 months. Copulation consists of a brief copulatory jump.

Females give birth to one to three spotted young, known as fawns, in mid- to late spring, generally in May or June. Fawns lose their spots during the first summer and weigh from 44 to 77 lb by the first winter. Male fawns tend to be slightly larger and heavier than females. For the first four weeks, fawns are hidden in vegetation by their mothers, who nurse them four to five times a day. This strategy keeps scent levels low to avoid predators. After about a month, the fawns are then able to follow their mothers on foraging trips. They are usually weaned after 8–10 weeks, but cases have been seen where mothers have continued to allow nursing long after the fawns have lost their spots as seen by rehabilitators and other studies. Males leave their mothers after a year and females leave after two.

Bucks are generally sexually mature at 1.5 years old and begin to breed even in populations stacked with older bucks.

White-tailed deer eat large amounts of food, commonly eating legumes and foraging on other plants, including shoots, leaves, cacti , prairie forbs, and grasses. They also eat acorns, fruit, and corn. Their special stomachs allow them to eat some things humans cannot, such as mushrooms and poison ivy. Their diets vary by season according to availability of food sources. They also eat hay, grass, white clover, and other foods they can find in a farm yard. Though almost entirely herbivorous, white-tailed deer have been known to opportunistically feed on nesting songbirds, field mice, and birds trapped in mist nets, if the need arises. A grown deer can eat around 2,000 lb of vegetable matter annually. A foraging area around 20 deer per square mile can start to destroy the forest environment.

The white-tailed deer is a ruminant, which means it has a four-chambered stomach. Each chamber has a different and specific function that allows the deer to eat a variety of different foods, digesting it at a later time in a safe area of cover. The stomach hosts a complex set of microbes that change as the deer's diet changes through the seasons. If the microbes necessary for digestion of a particular food are absent, it will not be digested.White-tailed deer have long been hunted as game, for pure sport and for their commodities. In some areas where their populations are very high, they are considered a pest, and hunting is used as a method to control it.

Several natural predators of white-tailed deer occur. Wolves, cougars, American alligators, jaguars , and humans are the most effective natural predators of white-tailed deer. These predators frequently pick out easily caught young or infirm deer , but can and do take healthy adults of any size. Bobcats, Canada lynx, bears, wolverines, and packs of coyotes usually prey mainly on fawns. Bears may sometimes attack adult deer, while lynxes, coyotes, and wolverines are most likely to take adult deer when the ungulates are weakened by harsh winter weather. Many scavengers rely on deer as carrion, including New World vultures, raptors, foxes, and corvids. Few wild predators can afford to be picky and any will readily consume deer as carrion. Records exist of American crows attempting to prey on white-tailed deer fawns by pecking around their face and eyes, though no accounts of success are given. Occasionally, both golden and bald eagles may capture deer fawns with their talons. In one case, a golden eagle was filmed in Illinois unsuccessfully trying to prey on a large mature white-tailed deer.

White-tailed deer typically respond to the presence of potential predators by breathing very heavily and fleeing. When they blow, the sound alerts other deer in the area. As they run, the flash of their white tails warns other deer. This especially serves to warn fawns when their mother is alarmed. Most natural predators of white-tailed deer hunt by ambush, although canids may engage in an extended chase, hoping to exhaust the prey. Felids typically try to suffocate the deer by biting the throat. Cougars and jaguars will initially knock the deer off balance with their powerful forelegs, whereas the smaller bobcats and lynxes will jump astride the deer to deliver a killing bite. In the case of canids and wolverines, the predators bite at the limbs and flanks, hobbling the deer, until they can reach vital organs and kill it through loss of blood. Bears, which usually target fawns, often simply knock down the prey and then start eating it while it is still alive. Alligators snatch deer as they try to drink from or cross bodies of water, grabbing them with their powerful jaws and dragging them into the water to drown.

Most primary natural predators of white-tailed deer have been basically extirpated in eastern North America, with a very small number of reintroduced red wolves, which are nearly extinct, around North Carolina and a small remnant population of Florida panthers, a subspecies of the cougar. Gray wolves, the leading cause of deer mortality where they overlap, co-occur with whitetails in northern Minnesota, Wisconsin, Michigan, and parts of Canada. This almost certainly plays a factor in the overpopulation issues with this species. Coyotes, widespread and with a rapidly expanding population, are often the only major nonhuman predator of the species, besides an occasional domestic dog. In some areas, American black bears are also significant predators. In northcentral Pennsylvania, black bears were found to be nearly as common predators of fawns as coyotes. Bobcats, still fairly widespread, usually only exploit deer as prey when smaller prey is scarce. Discussions have occurred regarding the possible reintroduction of gray wolves and cougars to sections of the eastern United States, largely because of the apparent controlling effect they have through deer predation on local ecosystems, as has been illustrated in the reintroduction of wolves to Yellowstone National Park and their controlling effect on previously overpopulated elk. However, due to the heavy urban development in much of the East and fear for livestock and human lives, such ideas have ultimately been rejected by local communities and/or by government services and have not been carried through.

In areas where they are heavily hunted by humans, deer run almost immediately from people and are quite wary even where not heavily hunted. In most areas where hunting may occur deer seem to develop an acute sense of time and a fondness for metro parks and golf courses. This rather odd occurrence is best noted in Michigan, where in the lower peninsula around late August early September they begin to move out of less developed areas in favor of living near human settlements.

The deer of Virginia can run faster than their predators and have been recorded at speeds of 75 km per hour; this ranks them amongst the fastest of all cervids, alongside the Eurasian roe deer. They can also jump 2.7 m high and up to 10 m in length. When shot at, the white-tailed deer will run at high speeds with its tail down. If frightened, the deer will hop in a zig-zag with its tail straight up. If the deer feels extremely threatened, however, it may charge the person or predator causing the threat, using its antlers or, if none are present, its head to fight off the threat.

Many keep white-tailed deer as pets. They are very smart, affectionate, curious and playful. However, on multiple occasions, during mating season, bucks kept as pets were very aggressive and resulted in severe injuries in their owners. Some areas ban the keeping of white-tailed deer in captivity, while others advocate the trapping and keeping of wild deer as an alternative to hunting due to high populations.
However, this is illegal across many U.S. states, as it is considered dangerous; a white-tailed deer's large antlers can impale and kill if that is what the deer intends. Any deer found being held captive will be killed by law enforcement officers in order to prevent the spread of any diseases the deer may have obtained.

In the U.S., the species is the state animal of Arkansas, Illinois, Michigan, Mississippi, Nebraska, New Hampshire, Ohio, Pennsylvania, and South Carolina, the wildlife symbol of Wisconsin, and game animal of Oklahoma. The profile of a white-tailed deer buck caps the coat of arms of Vermont and can be seen in the flag of Vermont and in stained glass at the Vermont State House. It is the national animal of Honduras and Costa Rica and the provincial animal of Canadian Saskatchewan and Finnish Pirkanmaa. Texas is home to the most white-tailed deer of any U.S. state or Canadian province, with an estimated population of over four million. Notably high populations of white-tailed deer occur in the Edwards Plateau of Central Texas. Michigan, Minnesota, Iowa, Mississippi, Missouri, New Jersey, Illinois, Wisconsin, Maryland, New York, North Dakota, Ohio, Pennsylvania, and Indiana also boast high deer densities. In 1884, one of the first hunts of white-tailed deer in Europe was conducted in Opočno and Dobříš , in what is now the Czech Republic.
