Tree squirrels are the members of the squirrel family (Sciuridae) commonly just referred to as "squirrels". They include more than 100 arboreal species native to all continents except Antarctica and Oceania .
60-551: The Indian giant squirrel or Malabar giant squirrel ( Ratufa indica ) is a large multi-coloured tree squirrel species endemic to forests and woodlands in India . It is a diurnal , arboreal , and mainly herbivorous squirrel . This species is endemic to India, with main sections of its distribution in the Western Ghats , Eastern Ghats and Satpura Range as far north as Madhya Pradesh (approximately 22° N ). It
120-619: A health risk to humans. In 2007 in the northern New Jersey community of Ringwood , the New Jersey Department of Health and Senior Services issued a warning to anyone who eats squirrel (especially children and those who are pregnant) to limit their consumption after a lead -contaminated squirrel was found near the Ringwood Mines Landfill . Toxic waste had been illegally dumped at this location for many years, before authorities cracked down on this practice in

For most of the history of the United Kingdom , squirrel has been a meat not commonly eaten, and even scorned by many. In the early 21st century however, the wild squirrel has become a more popular meat to cook with, showing up in restaurants and shops more often in Britain as a fashionable alternative meat. Specifically, Britons are cooking with
240-450: A college campus or parks, somebody brought them in because they thought it would be neat to have white squirrels around." Albert Meier, another biology professor at Western Kentucky University, added that: "... white squirrels rarely survive in the wild because they can't easily hide. But on a college campus, they are less likely to be consumed by other animals." Marmot 15, see text Marmots are large ground squirrels in
300-506: A conspicuous one-, two-, or three-toned colour scheme. The colours involved can be whitish, creamy - beige , buff , tan , rust , reddish- maroon , brown, dark seal brown , or black. The underparts and the front legs are usually cream coloured, and the head can be brown or beige, and there is a distinctive white spot between the ears. Otherwise the colours depend on the subspecies . Ten subspecies have been described, but recent authorities generally recognise four: The Indian giant squirrel
360-515: A contagious prion agent in squirrels. Nonetheless, the Lancet article generated substantial media coverage, including articles in the New Yorker and New York Times . A 2015 case of CJD in a Pittsburgh man who had eaten squirrel brains played out similarly: the media seized on the patient's unconventional food choice, positing squirrel brains as the source of his disease. The doctor who made
420-479: A direct attempt to help the native red squirrel , which has been dwindling since the 19th-century introduction of the gray squirrel, resulting in dramatic habitat loss for the indigenous red squirrels. This factor was marketed by a national "Save Our Squirrels" campaign that used the slogan, "Save a red, eat a grey!" As with other wild game and fish species, the consumption of squirrels that have been exposed to high levels of pollution or toxic waste poses
480-518: A marmot was printed and distributed as early as 1605 by Jacopo Ligozzi , who was noted for his images of flora and fauna. The etymology of the term "marmot" is uncertain. It may have arisen from the Gallo-Romance prefix marm- , meaning to mumble or murmur (an example of onomatopoeia ). Another possible origin is postclassical Latin , mus montanus , meaning "mountain mouse". Beginning in 2010, Alaska celebrates February 2 as " Marmot Day ",
540-433: A newly hired policeman in trying to remove a frantic squirrel from a homeowner's living room, which results in personal injury and a small fire. First aired in 1998, this episode turned out to be one of the most popular ones of the series, prompting rebroadcasts and a lead position on the two-CD compilation Crimebusters + Crossed Wires: Stories from This American Life . One of the ways that squirrels affect human society
600-502: A population of albino squirrels since the 1960s), and Youngstown State University in Youngstown, Ohio . Michael Stokes, a biology professor at Western Kentucky University, commented that the probable cause for the abundance of white squirrels on university campuses was because they were originally introduced by someone: "We're not sure how they got here, but I'll tell you how it usually happens...When you see them, especially around
660-535: A squirrel on the other, serving as her messengers to the sky and the earth respectively. In Europe during the Middle Ages , squirrels were sometimes used in bestiaries as symbols of greed and avarice on account of their storing of nuts, but, in the nineteenth century, British natural history books often praised them as thrifty for this same reason. A myth told by the Ainu people of Japan holds that squirrels are

#1732779610389720-515: A variety of vegetation. While most species are various forms of earthen-hued brown, marmots vary in fur coloration based roughly on their surroundings. Species in more open habitat are more likely to have a paler color, while those sometimes found in well- forested regions tend to be darker. Marmots are the heaviest members of the squirrel family. Total length varies typically from about 42 to 72 cm (17 to 28 in) and body mass averages about 2 kg ( 4 + 1 ⁄ 2 lb) in spring in
780-509: Is tree nuts . Red squirrels store nuts in a single stash (a midden ) that tends to dry out, so the seeds don't take root. Fox squirrels and gray squirrels bury nuts over a widespread area ( scatterhoarding ), and often forget them, resulting in new trees ( mutualism ). In the Ramayana , an ancient Sanskrit epic poem , a squirrel assists in constructing a bridge from India to Sri Lanka to help Rama rescue his wife Sita . Rama rewards
840-458: Is a list of all Marmota species recognized by Thorington and Hoffman plus the recently defined M. kastschenkoi . They divide marmots into two subgenera . Some extinct species of marmots are recognized from the fossil record, for example: Marmots have been known since antiquity. Research by the French ethnologist Michel Peissel claimed the story of the " Gold-digging ant " reported by
900-479: Is an upper-canopy dwelling species, which rarely leaves the trees, and requires "tall profusely branched trees for the construction of nests." It travels from tree to tree with jumps of up to 6 m (20 ft). When in danger, the Indian giant squirrel often freezes or flattens itself against the tree trunk, instead of fleeing. Its main predators are the birds of prey like owls and the leopard . This giant squirrel
960-399: Is available because they cache the surplus. Squirrels living in parks and campuses in cities have learned that humans are typically a ready source of food, either deliberately or from careless disposal of surplus. Some people do " squirrel fishing " as a way of simultaneously playing with and feeding squirrels. Humans commonly offer various nuts and seeds; however, wildlife rehabilitators in
1020-625: Is called a " drey ". Squirrels are a serious fire hazard when they break into buildings. They often treat exposed power cables as tree branches, and gnaw on the electrical insulation . The resulting exposed conductors can short out, causing a fire. For this reason alone, squirrel nests inside buildings cannot be safely ignored. A squirrel nest will also cause problems with noise, excreta , unpleasant odors, and eventual structural damage. Some homeowners resort to more interesting ways of dealing with this problem, such as collecting and placing fur from pets such as domestic cats and dogs in attics. It
1080-422: Is exposed to the weather. Poisoning squirrels can be problematic because of the risks to other animals or children in the building, and because the odor of a dead squirrel in an attic or wall cavity is very unpleasant and persistent. Trapping is often used to remove squirrels from residential structures. Effective baits include fruit, peanut butter , nuts, seeds and vanilla extract . An alternative method
1140-480: Is found at altitudes of 180–2,300 m (590–7,550 ft) in tropical deciduous , semi-deciduous (where often utilizing denser riparian growth ), and moist evergreen forests and woodlands. In general, its distribution is fragmented because it is intolerant of habitat degradation. The Indian giant squirrel generally nests in taller trees with a mean height of 11 m (36 ft) (±3 m (10 ft) SD ) in order to avoid predators. The Indian giant squirrel
1200-501: Is home to a white squirrel population which has spurred the myth of the albino squirrel as a good luck charm. There are many versions of the tale; one of the more popular versions is if one spots the albino squirrel before an exam, they will ace it. The University of North Texas founded the Albino Squirrel Preservation Society in 2001, which has since acquired several "worldwide" chapters. In 2006,
1260-451: Is hoped that this fur would indicate to nesting squirrels that a potential predator roams, and will encourage evacuation. Odoriferous repellents, including mothballs and ammonia , are generally ineffective in expelling squirrels from buildings. Once established in a nest, squirrels ignore fake owls and scarecrows , along with bright flashing lights, loud noises, and ultrasonic or electromagnetic devices. However, squirrels must leave

They can readily climb a power pole and crawl or run along a power cable. The animals will climb onto power transformers or capacitors looking for food, or a place to cache acorns . If they touch a high voltage conductor and a grounded portion of
1380-423: Is inspired by the fascination that people seem to have over local populations of white squirrels (often misidentified as being albino). This manifests itself by the creation of social group communities that form from a commonly shared interest in these rare animals. Other impacts on human society inspired by white squirrels include the creation of organizations that seek to protect them from human predation , and
1440-624: Is mostly active in the early hours of the morning and in the evening, resting in the midday. They are typically solitary animals that only come together for breeding. The species is believed to play a substantial role in shaping the ecosystem of its habitat by engaging in seed dispersal. The diet includes fruit, flowers, nuts and tree bark. They may also eat insects and bird eggs. The Indian giant squirrel lives alone or in pairs. They build large globular nests of twigs and leaves, placing them on thinner branches where large predators can't get to them. These nests become conspicuous in deciduous forests during
1500-500: Is no tracking system to determine the total extent of the losses. In regions where squirrels are plentiful, tire-flattened roadkill is a common sight on roadways, especially in the spring and fall, when there is a fresh crop of young rodents. Motorists have caused serious accidents by attempting to swerve or stop to avoid a squirrel in the road. Evasive maneuvers are difficult since squirrels are much more agile and have much quicker reaction times than motorists in heavy vehicles;
1560-481: Is not classified in the genus Marmota , but in the related genus Cynomys . Marmots typically live in burrows (often within rockpiles, particularly in the case of the yellow-bellied marmot ), and hibernate there through the winter. Most marmots are highly social and use loud whistles to communicate with one another, especially when alarmed. Marmots mainly eat greens and many types of grasses , berries , lichens , mosses , roots , and flowers . The following

Tree squirrel They do not form a single natural, or monophyletic , group; they are variously related to others in the squirrel family, including ground squirrels , flying squirrels , marmots , and chipmunks . The defining characteristic used to determine which species of Sciuridae are tree squirrels is dependent on their habitat rather than their physiology . Tree squirrels live mostly among trees, as opposed to those that live in burrows in
1800-427: Is to wait until squirrels have left in search of food, and then close up all their access openings, or to install one-way trap doors or a carefully angled pipe. Attempting to get rid of all squirrels in a neighborhood is generally a futile goal; the focus instead should be on physically excluding them from places where they can do damage. There are other humane techniques to remove squirrels from buildings, but removal

These herbivores are active during the summer, when they can often be found in groups, but are not seen during the winter, when they hibernate underground. They are the heaviest members of the squirrel family. Marmots are large rodents with characteristically short but robust legs, enlarged claws which are well adapted to digging, stout bodies, and large heads and incisors to quickly process
2100-593: The red squirrel was hunted for its blue-gray winter coat, traditionally called vair , which now lends its name to a heraldic fur . The hairs from squirrel tails are prized in fly fishing when tying fishing flies . In many areas of the US, squirrels are still hunted for food, as they were historically. Recipes calling for squirrel even appear in cookbooks, including James Beard's American Cookery and pre-1997 copies of The Joy of Cooking . Squirrel meat can be substituted for rabbit or chicken in many recipes and

Many tree squirrel species have adapted to human-altered environments such as rural farms , suburban backyards and urban parks . Current taxonomy , based on genetic data, splits the tree squirrels into several subfamilies. The following genera of the squirrel family are classified as tree squirrels. Squirrels are generally inquisitive and persistent animals. In residential neighborhoods, they are notorious for tenaciously trying to circumvent obstacles in order to eat from bird feeders . Although they are expert climbers, and primarily arboreal , some species of squirrels also thrive in urban environments, where they have adapted to humans. Squirrels have been kept as pets in Western society at least until
2220-515: The 1980s. In 1997, doctors in Kentucky published a paper in the Lancet that considered a possible association between the local tradition of consuming squirrel brains and five cases of Creutzfeldt–Jakob disease , a rare but serious prion -based disorder. The authors posed this as a mere possibility, unconfirmed by either post-mortem analysis of the patients' brain tissue , or identification of
2280-527: The 19th century. Because of their small size and tame nature, they were especially popular with women and the clergy. Squirrels are sometimes considered pests because of their propensity to chew on various edible and inedible objects, and their stubborn persistence in trying to get what they want. Their characteristic gnawing trait also aids in maintaining sharp teeth , and because their teeth grow continuously, prevents their over-growth. On occasion, squirrels will chew through plastic and even metal to get to

Squirrels have brought down the high-tech NASDAQ stock market twice and were responsible for a spate of power outages at the University of Alabama . To sharpen their teeth, squirrels will often chew on tree branches or even the occasional live power line. Rubber or plastic plates, or freely rotating sleeves ("squirrel guards") are sometimes used to discourage access to these facilities. Squirrels otherwise appear to be safe and pose almost zero risk of transmitting rabies . Squirrels cause economic losses to homeowners, nut growers, and forest managers in addition to damage to electric transmission lines. These losses include direct damage to property, repairs, lost revenue and public relations. While dollar costs of these losses are sometimes calculated for isolated incidents, there
2760-410: The field have noted that neither raw nor roasted peanuts nor sunflower seeds are healthy for squirrels, because they are deficient in several essential nutrients. This type of deficiency has been found to cause metabolic bone disease , a somewhat common ailment found in malnourished squirrels. Squirrels are sometimes hunted as game animals , whether for their fur or as food. In the Middle Ages
2820-518: The food. Tree squirrels may bury food in the ground for later retrieval. Squirrels use their keen sense of smell to search for buried food, but can dig numerous holes in the process. This may become an annoyance to gardeners with strict landscape requirements, especially when the garden contains edibles. Homeowners in areas with a heavy squirrel population must be vigilant in keeping attics , basements , and sheds carefully sealed to prevent property damage caused by nesting squirrels. A squirrel nest
2880-428: The ground or among rocks. An exception is the flying squirrel that also makes its home in trees, but has a physiological distinction separating it from its tree squirrel cousins: special flaps of skin called patagia , acting as glider wings, which allow gliding flight . The best-known genus of tree squirrels is Sciurus , which includes the eastern gray squirrel of North America ( introduced to Great Britain in
2940-405: The hawk Veðrfölnir , who sits at the top of the tree keeping watch. According to Richard W. Thorington, Jr. and Katie E. Ferrell, this legend may have originated from the red squirrel's habit of giving a "scolding alarm call in response to danger", which some Norsemen may have imagined as insults. In Irish mythology , the goddess Medb is said to always have a bird perched on one shoulder and

Along with Olney, there are four other towns in North America that avidly compete with each other to be the official "Home of the White Squirrel", namely: Marionville, Missouri ; Brevard, North Carolina ; Exeter, Ontario ; and Kenton, Tennessee , each of which holds an annual white squirrel festival, among other things designed to promote their claim of "White Squirrel Capital". A list of white squirrel sightings around
3060-399: The initial report later clarified that he had not meant to assert the squirrel meat was the cause. Analysis of the patient's brain tissue ruled out the possibility of CJD acquired from food. As of 2018, Creutzfeldt–Jakob disease had never been identified in squirrels, and the association between squirrel consumption and CJD remained speculative.

Additionally, the novelty of a meat considered unusual or special has contributed to the spread of squirrel consumption. Due to the difficulty of a clean kill and other factors, the majority of squirrel eaten in the UK is acquired from professional hunters , trappers and gamekeepers . Some Britons are eating gray squirrel as
