31-538: The forest overstory is a relatively closed stand of mixed bottomland hardwoods. On higher elevations the predominant tree species are willow oak , water oak , Nuttall’s oak , rock elm , sweetgum , and persimmon . Important species in the lower elevations are overcup oak , bitter pecan , and honey locust , with cypress and tupelo gum being found in sloughs and old lakes. Understory species commonly found on Boeuf WMA include deciduous holly , hawthorn , swamp privet , rattan , greenbriar and grape . Boeuf has

93-526: A large stray dog in Lazo, Russia . Squirrel attacks on humans are exceedingly rare, but do occur. Whitaker examined the stomachs of 139 thirteen-lined ground squirrels and found bird flesh in four of the specimens and the remains of a short-tailed shrew in one; Bradley, examining the stomachs of white-tailed antelope squirrels , found at least 10% of his 609 specimens' stomachs contained some type of vertebrate, mostly lizards and rodents. Morgart observed

124-629: A near-cosmopolitan distribution. This further supports the hypothesis that the common ancestor of all squirrels, living and fossil, lived in North America, as these three most ancient lineages seem to have radiated from there; if squirrels had originated in Eurasia , for example, one would expect quite ancient lineages in Africa , but African squirrels seem to be of more recent origin. The main group of squirrels can be split into five subfamilies:

155-713: A period of diurnality during the summer. During hot periods, squirrels have been documented to sploot , or lay their stomachs down on cool surfaces. Squirrels, like other rodents, employ species-specific strategies to store food, buffering against periods of scarcity. In temperate regions, squirrels commonly cache nuts beneath leaf litter, inside hollow trees, or underground. However, in subtropical and humid environments, traditional caching can lead to mold growth, decomposition, or premature germination. To counteract these challenges, some squirrels, particularly in subtropical zones, hang nuts or mushrooms on tree branches. This behavior, believed to minimize fungal infections and reduce

186-1044: A shallow cup; it is one of the most prolific producers of acorns. The tree starts acorn production around 15 years of age, earlier than many oak species. Willow oaks can grow moderately fast (height growth up to 60 cm or 2 ft a year), and tend to be conic to oblong when young, rounding out and gaining girth at maturity (i.e. more than 50 years). The species is most common in the American south and eastern states. It can be found from Long Island Sound south to northern Florida , and west to southernmost Illinois , Missouri , Oklahoma , and eastern Texas . Its natural range extends into southeastern Pennsylvania and southern New Jersey . It has also historically been recorded as occurring in Lancaster, Bucks, Chester, Delaware, and Philadelphia counties, chiefly on wet sites, occasionally in drier, upland ones. Much of that area has been built over and developed since World War II , and

217-421: A tree headfirst. They do so by rotating their ankles 180 degrees, enabling the hind feet to point backward and thus grip the tree bark from the opposite direction. As their large eyes indicate, squirrels have excellent vision , which is especially important for the tree-dwelling species. Many also have a good sense of touch , with vibrissae on their limbs as well as their heads. The teeth of sciurids follow

248-473: A white-tailed antelope squirrel capturing and eating a silky pocket mouse . The living squirrels are divided into five subfamilies , with about 58 genera and some 285 species . The oldest squirrel fossil, Hesperopetes , dates back to the Chadronian (late Eocene , about 40–35 million years ago ) and is similar to modern flying squirrels. A variety of fossil squirrels, from the latest Eocene to

279-592: A wide variety of plants, as well as nuts , seeds , conifer cones , fruits , fungi , and green vegetation . Some squirrels, however, also consume meat, especially when faced with hunger. Squirrels have been known to eat small birds , young snakes , and smaller rodents, as well as bird eggs and insects . Some tropical squirrel species have shifted almost entirely to a diet of insects. Squirrels, like pigeons and other fauna, are synanthropes , in that they benefit and thrive from their interaction in human environments. This gradual process of successful interaction

310-744: Is called synurbanization, wherein squirrels lose their inherent fear of humans in an urban environment. When squirrels were almost completely eradicated during the Industrial Revolution in New York , they were later re-introduced to "entertain and remind" humans of nature. The squirrel blended into the urban environment so efficiently that when synanthropic behavior stops (i.e. people do not leave trash outside during particularly cold winters), they can become aggressive in their search for food. Aggression and predatory behavior has been observed in various species of ground squirrels, in particular

341-469: Is distinguished from most other oaks by its leaves , which are shaped like willow leaves, 5–12 centimeters (2– 4 + 3 ⁄ 4 inches) long and 1–2.5 cm ( 3 ⁄ 8 –1 in) broad with an entire (untoothed and unlobed) margin; they are bright green above, paler beneath, usually hairless but sometimes downy beneath. The fruit is an acorn , 8–12 millimeters ( 5 ⁄ 16 – 15 ⁄ 32  in) long, and almost as wide as long, with

372-729: Is of Common Germanic origin, cognates of which are still used in other Germanic languages , including the German Eichhörnchen (diminutive of Eichhorn , which is not as frequently used); the Norwegian ikorn / ekorn ; the Dutch eekhoorn ; the Swedish ekorre and the Danish egern . A group of squirrels is called a "dray" or a "scurry". Squirrels are generally small animals, ranging in size from

403-509: Is often marketed as "red oak" wood. The willow oak is one of the most popular trees for horticultural planting, due to its rapid growth, hardiness, balance between axial and radial dominance, ability to withstand both sun and shade, light green leaf color and full crown. Despite being heavily used in landscaping in the Southern US (in cities such as Washington, D.C. , Raleigh , Charlotte , and Atlanta ) around malls, along roads, etc.,

434-494: Is soft and silky, though much thicker in some species than others. The coat color of squirrels is highly variable between—and often even within—species. In most squirrel species, the hind limbs are longer than the forelimbs, while all species have either four or five toes on each foot. The feet, which include an often poorly developed thumb , have soft pads on the undersides and versatile, sturdy claws for grasping and climbing . Tree squirrels , unlike most mammals, can descend

465-530: Is very fine, making it better for tying fishing flies. When the squirrel sits upright, its tail folded up its back may stop predators looking from behind from seeing the characteristic shape of a small mammal. Squirrels live in almost every habitat, from tropical rainforest to semiarid desert , avoiding only the high polar regions and the driest of deserts . They are predominantly herbivorous , subsisting on seeds and nuts, but many will eat insects and even small vertebrates. Many juvenile squirrels die in

496-557: The African pygmy squirrel and least pygmy squirrel at 10–14 cm (3.9–5.5 in) in total length and just 12–26 g (0.42–0.92 oz) in weight, to the Bhutan giant flying squirrel at up to 1.27 m (4 ft 2 in) in total length, and several marmot species, which can weigh 8 kg (18 lb) or more. Squirrels typically have slender bodies with very long very bushy tails and large eyes. In general, their fur

527-644: The Callosciurinae , 60 species mostly found in South East Asia ; the Ratufinae , 4 cat-sized species found in south and southeast Asia ; the Sciurinae , which contains the flying squirrels (Pteromyini) and the tree squirrels , 83 species found worldwide; Sciurillinae , a single South American species; and Xerinae , which includes three tribes of mostly terrestrial squirrels, including

558-495: The Miocene , have not been assigned with certainty to any living lineage. At least some of these probably were variants of the oldest basal "protosquirrels" (in the sense that they lacked the full range of living squirrels' autapomorphies ). The distribution and diversity of such ancient and ancestral forms suggest the squirrels as a group may have originated in North America. Apart from these sometimes little-known fossil forms,

589-465: The phylogeny of the living squirrels is fairly straightforward. The three main lineages are the Ratufinae (Oriental giant squirrels), Sciurillinae and all other subfamilies. The Ratufinae contain a mere handful of living species in tropical Asia . The neotropical pygmy squirrel of tropical South America is the sole living member of the Sciurillinae. The third lineage, by far the largest, has

620-402: The thirteen-lined ground squirrel . For example, Bernard Bailey, a scientist in the 1920s, observed a thirteen-lined ground squirrel preying upon a young chicken . Wistrand reported seeing this same species eating a freshly killed snake . There has also been at least one report of squirrels preying on atypical animals, such as an incident in 2005 where a pack of black squirrels killed and ate

651-418: The willow oak , is a North American species of a deciduous tree in the red oak group of oaks . It is native to the south-central and eastern United States. It is a medium-sized tree growing to 20–30 meters (65–100 feet) tall (exceptionally to 39 m, 128 ft), with a trunk up to 1–1.5 m ( 3 + 1 ⁄ 2 –5 ft) in diameter (exceptionally 2 m or 6 + 1 ⁄ 2  ft). It

682-633: The Americas, Eurasia, and Africa, and were introduced by humans to Australia. The earliest known fossilized squirrels date from the Eocene epoch, and among other living rodent families, the squirrels are most closely related to the mountain beaver and dormice . The word squirrel , first attested in 1327, comes from the Anglo-Norman esquirel which is from the Old French escurel ,

713-493: The female alone looks after the young, which are weaned at six to ten weeks and become sexually mature by the end of their first year. In general, the ground-dwelling squirrel species are social, often living in well-developed colonies, while the tree-dwelling species are more solitary. Ground squirrels and tree squirrels are usually either diurnal or crepuscular , while the flying squirrels tend to be nocturnal —except for lactating flying squirrels and their young, which have

744-422: The first year of life. Adult squirrels can have a lifespan of 5 to 10 years in the wild. Some can survive 10 to 20 years in captivity. Premature death may occur when a nest falls from the tree, in which case the mother may abandon her young if their body temperature is not correct. Many such baby squirrels have been rescued and fostered by a professional wildlife rehabilitator until they could be safely returned to

775-496: The mortise-tenon joint in carpentry. Because squirrels cannot digest cellulose , they must rely on foods rich in protein , carbohydrates , and fats . In temperate regions, early spring is the hardest time of year for squirrels because the nuts they buried are beginning to sprout (and thus are no longer available to eat), while many of the usual food sources are not yet available. During these times, squirrels rely heavily on tree buds. Squirrels, being primarily herbivores , eat

806-499: The reflex of a Latin word sciurus , which was taken from the Ancient Greek word σκίουρος ( skiouros ; from σκία-ουρος ) 'shadow-tailed', referring to the long bushy tail which many of its members have. Sciurus is also the name of one of its genuses. The native Old English word for the squirrel, ācweorna , only survived into Middle English (as aquerne ) before being replaced. The Old English word

837-414: The risk of food loss, also inadvertently aids certain trees, like Cyclobalanopsis , in expanding their range, with forgotten or dislodged nuts sprouting in new locations, influencing forest ecology. Two species of flying squirrel, the particolored flying squirrel and Hainan flying squirrel aid such cacheing by carving grooves into the nuts to fix the nuts tightly between small intersecting twigs, akin to

868-419: The tree is now classified as endangered in the state. It is most commonly found growing on lowland floodplains , often along streams , but rarely also in uplands with poor drainage, up to 400 m (1,300 ft) in altitude. The acorns are eaten by squirrels and other wildlife. Economic uses are primarily as an ornamental tree and the wood for pulp and paper production, but also for lumber; it

899-451: The trees tend to grow larger than planners expect, which often leads to cracked sidewalks. Squirrel Squirrels are members of the family Sciuridae ( / s ɪ ˈ j uː r ɪ d eɪ , - d iː / ), a family that includes small or medium-sized rodents . The squirrel family includes tree squirrels , ground squirrels (including chipmunks and prairie dogs , among others), and flying squirrels . Squirrels are indigenous to

930-415: The typical rodent pattern, with large incisors (for gnawing) that grow throughout life, and cheek teeth (for grinding) that are set back behind a wide gap, or diastema . The typical dental formula for sciurids is 1.0.1.3 1.0.1.3 . The purposes of squirrels' tails, to benefit the squirrel, include: The hairs from squirrel tails are prized in fly fishing when tying fishing flies . Squirrel hair

961-510: The wild, although the density of squirrel populations in many places and the constant care required by premature squirrels means that few rehabilitators are willing to spend their time doing this and such animals are routinely euthanized instead. Squirrels mate either once or twice a year and, following a gestation period of three to six weeks, give birth to a number of offspring that varies by species. The young are altricial , being born naked, toothless, and blind. In most species of squirrel,
