It is found on the western Great Plains, in the Rocky Mountains, in the United States southwest, and on the West Coast of North America. for short periods. Class: Mammalia Mule deer have also been introduced to Argentina and Kauai, Hawaii.[5]. [14], In addition to movements related to available shelter and food, the breeding cycle is important in understanding deer behavior. BEHAVIOR - Mule deer behavior may also be negatively affected by winter-feeding efforts. Feet Member of this family occupy a wide range of habitats, from arctic tundras to tropical forests, and can be found over most of the world. Feeding deer is illegal in some jurisdictions. Changes in hormone levels are indications of physiological adjustments to the changes in the habitat. They will remain together for several days. Most are brown or gray in color, with white spots characterizing the young, and in a few species, the adults. Ears [11], In 99 studies of mule deer diets, some 788 species of plants were eaten by mule deer, and their diets vary greatly depending on the season, geographic region, year, and elevation. [22][23] In the Sierra Nevada range, mule deer depend on the lichen Bryoria fremontii as a winter food source.[24]. This race is markedly smaller than other mule deer, with an average weight of 54.5 kg (120 lb) and 36 kg (79 lb) in males and females, respectively. Family: Cervidae Mule Deer are browsers and eat a great variety of vegetable matter, including fresh green leaves, twigs, lower branches of trees, and various grasses. The average gross energy content of the consumed forage material is 4.5 kcal/g. ⦠Mule deer differ from white-tailed deer in many respects, including their general behavior, food habits, population dynamics and habitat preferences. [1][5][6][7][9][34] Mule deer apparently evolved from the black-tailed deer. Mule deer (Odocoileus hemionus) are the most common large mammal in Idaho. Feed AntlerMax® Mule Deer 16 deer feed free-choice with adequate forage or quality hay. Good trees include pears, apples, crab apples, persimmons, aspen, chestnuts, white oaks and red oaks, ash, aspen, maple, popular, willow, white ⦠The Best Deer Feed for Winter. Mule Deer breed in late November and early December. I usually start scouting at the end of June when all the hills are green. [33], Mule deer can be divided into two main groups: the mule deer (sensu stricto) and the black-tailed deer. Most mature bucks in good condition have lost theirs by the end of February; immature bucks generally lose them a little later. Diet and behavior. [5] The two main groups have been treated as separate species, but they hybridize, and virtually all recent authorities treat the mule deer and black-tailed deer as conspecific. The annual cycle of antler growth is regulated by changes in the length of the day. Cautions They are social animals, so zookeepers keep them in herds. Mule Deer have no canine teeth and, like the cow, have a multi-part stomach, the first two chambers of which act as temporary storage bins. In many cases, body size is also a key difference. Mule deer eat a wide variety of plant foods, utilizing the food that grows where they live. In this fashion, they can reach a speed of 45 m.p.h. Mule Deer have large ears that move constantly and independently, from whence they get their name, "Mule" or "Burro Deer." An extremely large buck can stand 42 inches at the shoulder, measure 7 feet long and weigh up to 330 pounds, with the average ⦠Generally, the California mule deer has a preference for hill terrain, especially an oak woodland habitat. Mule deer (Odocoileus hemionus) are easy to identify due to their large mule-like ears. Thatâs right, it is the correct feed for this time of year. They are also active overnight. All have slender legs. Food & Hunting The females go off by themselves and eventually give birth and nurse their young; the males wander in friendly twosomes or small bands throughout the summer months as antlers grow. Mule deer and black-tailed deer (collectively called mule deer, Odocoileus hemionus) are icons of the American West. The Mule Deer large ear is gray on the outside and white on the inside. Their large ears are distinctive. Fawns usually stay with the doe for the first full year. Learn more The hunters who have planted BioLogic are reporting good success with feeding different types of deer. The down side to this is the deer are harder to find this time of year due to the palatable food being so abundant. We also have some hunters in the West planting green fields for mule deer. The mule deer's tail is black-tipped, whereas the white-tailed deer's is not. Mule Deer have a very wide distribution out there. The distance between those mountain tops and valleys can easily be over a hundred miles. Genus: Odocoileus They may also consume partially rotted plants, as well as dry leaves, buds, fruit, flowers, sprouting grasses and herbs, the tips of some coniferous boughs, small twigs, and lichens that fall from trees. When startled, a Mule Deer will move in a series of stiff-legged jumps with all four feet hitting the ground together. From late spring to early fall, they gain weight and build fat reserves by feeding heavily on broad-leafed plants and grasses. Its scientific name is Odocoileus hemionus. Tips For Spotting & Hunting Mule Deer. (It's Free. Sub Family: Capreolinae crowding) is about seven. Hemionus means half-mule. Total body fat is a measure of the individual's energy reserves, while thyroid hormone concentrations are a metric to determine the deer's ability to use the fat reserves. Use only as indicated. Due to extremely good mule deer habitat with plenty of food and sound management practices by Colorado Parks and Wildlife, the state has the largest mule deer population in the country. We excluded references that contained statements of what desert mule deer eat based on gen- eral knowledge or casual observations. Mule Deer is a target for various viral, bacterial, and parasitic diseases. The idea is to locate a patch of food that attracts mule deer and set up an ambush spot within rifle range. Mule deer are commonly seen browsing in open, shrubby areas between dusk and dawn. During the winter and early spring, when there is little forage available, their diet is mostly leaves, stems and buds. Mule deer females usually give birth to two fawns, although if it is their first time having a fawn, they often have just one. Throughout the entire western United States, including the four deserts of the American Southwest The Mule Deer carries its thin, black-tipped tail drooped, unlike the uplifted, bushy white tail of its cousin. This water well provides a very dependable water source year-round and is used by the mule deer on a daily basis. White-tail deer are tan in color, with a larger tail. Now weâre seeing hunters in Washington State and Oregon planting green fields for blacktailed deer. There is some competition between the Mute Deer and the livestock on the range, especially in Spring and early Summer. Mule deer like to feed in the early morning and late evening. [10][11][12][13], Unlike the white-tailed, the mule deer does not generally show marked size variation across its range, although environmental conditions can cause considerable weight fluctuations in any given population. Purina ® Antler Advantage ® Mule Deer 22 ARS deer feed is a nutrition-packed, 22%-protein, pelleted ration with the Purina ® Advanced Rumen Support System designed to support the nutrition of mule deer in their native habitat. Does may mate with more than one buck and go back into estrus within a month if they did not become pregnant. Ambush locations for mule deer are near water sources, travel routes leading to food patches, and the food patches. Conservation Consult the feed tag on this package for specific feeding directions. [31] Forages consumed in the summer are higher in digestible components (i.e. Supplemental feeding efforts might be appropriate when carefully conducted under limited circumstances, but to be successful, the feeding must begin early in the severe winter (before poor range conditions and severe weather cause malnourishment or starvation) and must be continued until range conditions can support the herd. The mating season for Mule Deer reaches its peak in November and December, as antlered stags round up females and fight for their possession. They browse shrubs, trees and occasional grasses and forbs and retreat to tree cover to bed down during the day. Unfortunately, range management professionals have seen a common problem across many of Utah's sagebrush rangelands â they are suffering from the ecological equivalents of old age and malnutrition. [16] Fawns stay with their mothers during the summer and are weaned in the fall after about 60–75 days. Males and females mix freely while traveling together in groups during winter months, often down to the desert floor. Studies from Specimen Mountain in the park indicated shrubs comprised 73 percent of the animal's diet, with broad-leafed herbs an additional 26 percent. These studies confirm that mule deer feed primarily on woody plants including browse (leaves and twigs) and mast (fruit, beans and berries). [1][5][6][7][8][9], Unlike the related white-tailed deer (Odocoileus virginianus), which is found through most of North America east of the Rocky Mountains and in the valleys of the Rocky Mountains from Idaho and Wyoming northward, mule deer are only found on the western Great Plains, the Rocky Mountains, the southwest United States, and on the west coast of North America. All federal, state, and provincial land and wildlife management agencies recognize the fundamental need to maintain Mule Deer ranges and keep them habitable. The 243 acres of cropland on the property provides a steady annual income source and excellent food sources for the deer. Their diet is mostly hay and pelleted food, with fruits and veggies mixed in. Two subspecies of mule deer are grouped into the black-tailed deer. Mule deer are concentrate feeders; that is, they carefully select highly nutritious bits of forage. The throat patch, rump patch, inside ears and inside legs are white with lower portions running cream to tan. The mature buck seems to prefer rocky ridges for bedding grounds, while the doe and fawn is more likely to bed down in the open. The habitat varies largely due to the massive range of mule deer across western North ⦠This inactivity during the heat of the day is a behavioral adaptation to the desert environment that conserves water and keeps the body temperature within livable limits. If necessary, they can turn or completely reverse direction in the course of a single bound. For example, heavy amounts of gastrointestinal nematodes may cause death in Mule Deer. It is a browser and typically takes over 90% of its diet from shrubs and leaves and the balance from grasses. Planting food plots is an effective, safe, and legal way to support local deer populations. These groups must have plenty of space to roam, and a variety of different plants to browse on. [15] The survival rate of the fawns during labor is about 50%. From April through June, after about a 200-day gestation period, the doe delivers 1 to 4 young (normally 2). [30] Because some of the subspecies of mule deer are migratory, they encounter variable habitats and forage quality throughout the year. Mule deer are the largest of the two deer species in Idaho. Food of the Mule Deer is quite varied. Males grow forked antlers that have 8 to 10 points and spread as much as 4 feet (1.2 m). The most noticeable differences between white-tailed and mule deer are ear size, tail color, and antler configuration. Zoos have never kept some subspecies, while they more commonly keep others. Ensuring the conservation of mule deer, black-tailed deer and their habitat. They are brownish-gray in color, have a white rump patch and a small white tail with a black tip. [8][9] Many claims of observations of wild hybrids are not legitimate, as identification based on external features is complicated. Deer kill about 150-170 people each year, from car accidents, and because people underestimate how dangerous they really are. Another physical adaptation, its larger feet, allows the Mule Deer to claw out water as much as two feet deep, which it detects with its keen sense of smell. In fact, they seem to be able to live just about anywhere as long as they have food, shelter, and access to water. Bears and smaller-sized carnivores are typically opportunistic feeders, and pose little threat to a strong, healthy mule deer. Mule Deer Distribution. Life span in the wild is 10 years, but Mule Deer have lived up to 25 years in captivity . Related Species [18][20], Mule deer readily adapt to agricultural products and landscape plantings. Triiodothyronine (T3) hormone is directly involved with basal metabolic rate and thermoregulation. Each spring, a buck's antlers start to regrow almost immediately after the old antlers are shed. We included plant species in our summary if 2 1 study reported their contribution to the diet as 2 ⦠They are particularly fond of blackberry and raspberry vines, grapes, mistletoe, mushrooms and ferns. Behaviors important to mule The Mule Deer is slower and less colorful than the White-tailed Deer, but its pastel, gray-buff color provides a physical adaptation to the desert environment which disguises it from predators like the Cougar, the Coyote and the eagle who will swoop down on a fawn. [26], Mule deer are variably gregarious, with a large proportion of solitary individuals (35 to 64%) and small groups (groups with ≤5 deer, 50 to 78%). The Mule Deer, while closely related to the eastern species-the white-tailed deer, are remarkably distinct in their biological, ecological, and behavioral attributes. During the summer, the coat on its upper body is yellow- or reddish-brown, while in winter more gray. [32] Due to fluctuations in forage quality and availability, mule deer fat storage varies throughout the year, with the most fat stored in October, which is depleted throughout the winter to the lowest levels of fat storage in March. This stocky deer with sturdy legs is 4 to 6-1/2 feet in length and 3 to 3-1/2 feet high at the shoulder. California mule deer usually ⦠[15][17], The size of mule deer groups follows a marked seasonal pattern. During early weeks of life, the fawn sees its mother only at mealtimes for feeding. [15], A buck's antlers fall off during the winter, then grow again in preparation for the next season's rut. Despite a serious overpopulation of deer on the North Kaibab in the 1920s, Mule deer numbers appeared to decline in the rest of the state. This type of food is easiest for deer to digest, which is what makes it ideal for supplemental feeding. The mule deer is the larger of the two Odocoileus species on average, with a height of 80–106 cm (31–42 in) at the shoulders and a nose-to-tail length ranging from 1.2 to 2.1 m (3.9 to 6.9 ft). Deep snows ultimately limit useable range to a fraction of the total. Males are larger than females. Trophy mule deer hunts take place in a wide variety of locations from fields, creek bottoms, food plots, shelter belts, rough country, to open prairies of South Dakota. [34], The 10 valid subspecies, based on the third edition of Mammal Species of the World, are:[5], Game animals and shooting in North America, "Tails with a Dark Side: The truth about whitetail–mule deer hybrids", "North American Deer: Mule, Whitetail and Coastal Blacktail Deer", "Mule Deer Odocoileus hemionus (Rafinesque)", "Sitka Black-tailed Deer Hunting Information", "DWR Biologists Use Helicopter Rides, Ultrasound, To Check on Deer Pregnancies", "Infectious Disease and Grouping Patterns in Mule Deer", "Mule Deer (Odocoileus hemionus) Fact Sheet", "Lichens in relation to management issues in the Sierra Nevada national parks", Mule Deer: Changing Landscapes, Changing Perspectives: Supplemental Feeding—Just Say No, "Causes and consequences of sociality in mule deer", "Comparing radio-tracking and visual detection methods to quantify group size measures", "Herbivore Body Condition Response in Altered Environments: Mule Deer and Habitat Management", "Status of the name Odocoileus hemionus crooki (Mammalia: Cervidae)", Proceedings of the Biological Society of Washington, Encyclopedia of Life page on the mule deer, https://en.wikipedia.org/w/index.php?title=Mule_deer&oldid=998764462, Fauna of the California chaparral and woodlands, Taxa named by Constantine Samuel Rafinesque, Short description is different from Wikidata, Creative Commons Attribution-ShareAlike License, This page was last edited on 6 January 2021, at 22:56.
