104-567: Great Bridge opened in 1907, holding students from 1st through 12th grade. Another larger building opened in 1924, which also housed students from 1st through 11th grade. In 1954, Great Bridge moved to another new larger building which accommodated students in 6th through 12th grade. This building has now become the site of Great Bridge Middle School. In 1983, the current site of Great Bridge High School opened and accommodated students in 10th through 12th grade. The school would later accommodate students in 9th through 12th grade. The school team mascot

208-511: A 'stronghold' place and eats its food in a high tree or on an inaccessible ledge. Lynx populations decrease when wolves appear in an area, such as observed in the Pritelsk region of the Altai Mountains , and lynx are likely to take smaller prey where wolves are active. In eastern Slovakia , after an increase of wolves after World War II, lynx were observed to move out. However, there is also

312-404: A June 20, 2012, report of a New Hampshire roadkill specimen listed the animal's weight at 27 kg (60 lb). The largest-bodied bobcats were recorded in eastern Canada and northern New England, and the smallest in the southern Appalachian Mountains . Consistent with Bergmann's rule , the bobcat is larger in its northern range and in open habitats. A morphological size comparison study in

416-408: A black-tipped, stubby (or "bobbed") tail, from which it derives its name. It reaches a total length (including the tail) of up to 125 cm (50 in). It is an adaptable predator inhabiting wooded areas, semidesert, urban edge, forest edge, and swampland environments. It remains in some of its original range, but populations are vulnerable to extirpation by coyotes and domestic animals. Though

520-498: A bobcat was captured in 2018 on a tourist boat in Downtown Pittsburgh , Pennsylvania . In addition, bobcat sightings have been confirmed in northern Indiana, and one was killed near Albion, Michigan, in 2008. In early March 2010, a bobcat was sighted (and later captured by animal control authorities) in a parking garage in downtown Houston . By 2010, bobcats appear to have recolonized many states, occurring in every state in

624-798: A carcass is confirmed. Like other Lynx species, bobcats probably avoid encounters with bears, in part because they are likely to lose kills to them or may rarely be attacked by them. Bobcat remains have occasionally been found in the resting sites of male fishers . American alligators ( Alligator mississippensis ) have been filmed opportunistically preying on adult bobcats in the southeast United States. Golden eagles ( Aquila chrysaetos ) have been reportedly observed preying on bobcats. Kittens may be taken by several predators, including great horned owls , eagles , foxes , and bears , and other adult male bobcats. When prey populations are not abundant, fewer kittens are likely to reach adulthood. Diseases, accidents, hunters, automobiles, and starvation are

728-585: A chance to consume its kill itself. The Eurasian lynx is included on CITES Appendix II and listed as a protected species in the Berne Convention on the Conservation of European Wildlife and Natural Habitats , Appendix III. Hunting lynx is illegal in many range countries, with the exception of Estonia, Latvia, Russia, Armenia and Iraq. Since 2005, the Norwegian government sets national population goals, while

832-666: A daily prey intake of about 900 g (32 oz). It is therefore classified as lagomorph specialist. Diet studies in central Asia and Yakutia also indicate a diet mainly composed of lagomorphs and ungulate prey contributes in low amounts to lynx diet. Eurasian lynx scat found in Dolpa District in the Nepal Himalayas contained remains of woolly hare ( Lepus oiostolus ), pika ( Ochotona sp.), mountain voles ( Alticola sp.), Himalayan marmot ( Marmota himalayana ) and domestic goat ( Capra hircus ). The mating season of

936-521: A dominance hierarchy is often established, resulting in the exclusion of some transients from favored areas. In line with widely differing estimates of home range size, population density figures diverge from one to 38 bobcats per 26 km (10 sq mi) in one survey. The average is estimated at one bobcat per 13 km (5 sq mi). A link has been observed between population density and sex ratio. An unhunted population in California had

1040-554: A forest-steppe mixed ecosystem in northwestern Anatolia by camera traps, genetic material and radiotelemetry between 2009 and 2019. In Kars Province , a breeding population occurs in Sarıkamış-Allahuekber Mountains National Park . The Eurasian lynx and grey wolf can occur sympatrically , as they occupy different trophic niches. In Central Asia , it is native to Kazakhstan , Uzbekistan , Turkmenistan , Kyrgyzstan , Tajikistan , Afghanistan and

1144-569: A gestation period of about two months. Two subspecies are recognized: one east of the Great Plains , and the other west of the Great Plains. It is featured in some stories of the indigenous peoples of North and Central America, and in the folklore of European-descended inhabitants of the Americas. Felis rufa was the scientific name proposed by Johann Christian Daniel von Schreber in 1777. In

1248-468: A home range is necessary for breeding; studied animals without a home range had no identified offspring. The female has an estrous cycle of 44 days, with the estrus lasting five to ten days. Bobcats remain reproductively active throughout their lives. The female raises the young alone. One to six, but usually two to four, kittens are born in April or May, after roughly 60 to 70 days of gestation . Sometimes,

1352-521: A number of different behaviors, including bumping, chasing, and ambushing. Other males may be in attendance, but remain uninvolved. Once the male recognizes the female is receptive, he grasps her in the typical felid neck grip and mates with her . The female may later go on to mate with other males, and males generally mate with several females. During courtship, the bobcat's vocalizations include screaming and hissing. Research in Texas revealed that establishing

1456-529: A poison-weakened immune system is less capable of fighting off mange. Liver autopsies in California bobcats that have succumbed to notoedric mange have revealed chronic rodenticide exposure. Alternative rodent control measures such as vegetation control and use of traps have been suggested to alleviate this issue. Stories featuring the bobcat, in many variations, are found in some Indigenous cultures of North America, with parallels in South America. A story from

1560-633: A reported instance of a male lynx having expelled an adult and apparently healthy male wolf in Belarus in a fight. After the incident, the wolf vanished from the record, suggesting that it might have succumbed to the wounds sustained during the fight. Moreover, recent population dynamics and a high mortality rate among wolf cubs in the Naliboki forest might be connected to an increasing lynx population. All in all, this suggests that, at least locally, lynx may dominate wolves, since no signs for predation of wolves on lynx

1664-527: A second litter is born as late as September. The female generally gives birth in an enclosed space, usually a small cave or hollow log. The young open their eyes by the ninth or tenth day. They start exploring their surroundings at four weeks and are weaned at about two months. Within three to five months, they begin to travel with their mother. They hunt by themselves by fall of their first year, and usually disperse shortly thereafter. In Michigan, however, they have been observed staying with their mother as late as

1768-403: A sex ratio of 2.1 males per female. When the density decreased, the sex ratio skewed to 0.86 males per female. Another study observed a similar ratio, and suggested the males may be better able to cope with the increased competition, and this helped limit reproduction until various factors lowered the density. The bobcat is able to survive for long periods without food, but eats heavily when prey

1872-446: A short "bobbed" tail with an all-black tip, black tufts of hair on its ears, and a long grey-and-white ruff. It is the largest of the four lynx species, ranging in body length from 76–106 cm (30–42 in) in males; 73–99 cm (29–39 in) in females; and standing 55–75 cm (22–30 in) at the shoulder. The tail is 11–24.5 cm (4.3–9.6 in) long, constituting a total length of up to 130 cm (51 in) in

1976-496: A tamed and cherished pet or possible spiritual significance. The Hopewell normally buried their dogs, so the bones were initially identified as remains of a puppy, but dogs were usually buried close to the village and not in the mounds themselves. This is the only wild cat decorated burial on the archaeological record. An inhabitant of Appalachia , Lynx rufus is immortalized (along with university founder Rufus Putnam ) at Ohio University through its popular college mascot, Rufus

2080-596: A threat to smaller ruminants such as pigs , sheep and goats . According to the National Agricultural Statistics Service , bobcats killed 11,100 sheep in 2004, comprising 4.9% of all sheep predator deaths. However, some amount of bobcat predation may be misidentified, as bobcats have been known to scavenge on the remains of livestock kills by other animals. It has been known to kill deer or pronghorn , and sometimes to hunt elk in western North America, especially in winter when smaller prey

2184-534: A typical adult lynx kills about 60 roe deer a year; in the years when the roe deer population plummets, the lynx switch to beavers, hares, foxes, raccoon dogs, and birds. Even where roe deer are quite uncommon, the deer are still quantitatively the favored prey species, though in summer smaller prey and occasional domestic sheep are eaten more regularly. In parts of Finland , introduced white-tailed deer are eaten regularly. In some areas in Poland and Austria , red deer

2288-681: Is European hare , forming 79% to 99% of prey biomass eaten. Although the lynx is in sympatry with wild ungulates, such as wild goat, chamois, red deer and wild boar in these ecosystems, ungulate biomass in lynx diet does not exceed 10%. In ten other study sites in the Black Sea region of northern Anatolia where roe deer can occur in high densities, lynx occurrence is positively correlated with European hare occurrence rather than roe deer. Lynx in Anatolia also has physiological requirements and morphological adjustments similar to other lagomorph specialists, with

2392-712: Is 47.5–125 cm (18.7–49.2 in) long from the head to the base of its distinctive stubby tail, averaging 82.7 cm (32.6 in); the tail is 9 to 20 cm (3.5 to 7.9 in) long. Its " bobbed " appearance gives the species its name. An adult stands about 30 to 60 cm (12 to 24 in) at the shoulders. Adult males can range in weight from 6.4–18.3 kg (14–40 lb), with an average of 9.6 kg (21 lb); females at 4–15.3 kg (8.8–33.7 lb), with an average of 6.8 kg (15 lb). The largest bobcat accurately measured on record weighed 22.2 kg (49 lb), although unverified reports have them reaching 27 kg (60 lb). Furthermore,

2496-410: Is abandoned two to three months after the kittens are born, but the young typically remain with their mother until they are around ten months of age. Eurasian lynx reach sexual maturity at two or three years, and have lived for twenty one years in captivity. Females usually have two kittens; litters with more than three kittens are rare. The primary predators of the lynx are the gray wolf and, in

2600-445: Is abundant. During lean periods, it often preys on larger animals, which it can kill and return to feed on later. The bobcat hunts by stalking its prey and then ambushing with a short chase or pounce. Its preference is for mammals weighing about 0.7–6 kg ( 1 + 1 ⁄ 2 – 12 + 1 ⁄ 2  lb). Its main prey varies by region: in the eastern United States, it is the eastern cottontail and New England cottontail , and in

2704-417: Is an adaptable species. It prefers woodlands— deciduous , coniferous , or mixed—but does not depend exclusively on the deep forest. It ranges from the humid swamps of Florida to desert lands of Texas or rugged mountain areas. It makes its home near agricultural areas, if rocky ledges, swamps, or forested tracts are present; its spotted coat serves as camouflage. The population of the bobcat depends primarily on

2808-525: Is estimated to be nowadays larger than ever before. Limited hunting is permitted. In 2009 the Finnish Ministry of Agriculture and Forestry gave a permit for hunting of 340 lynx individuals. In Great Britain , subfossil remains of Eurasian lynx have been dated to the early Middle Ages , and the 7th or 8th century Welsh poem Dinogad's Smock likely makes reference to the presence of lynx in Cumbria . It

2912-463: Is lined with feathers, deer hair, and dry grass to provide bedding for the young. At birth, Eurasian lynx kittens weigh 240 to 430 g (8.5 to 15.2 oz) and open their eyes after ten to twelve days. They initially have plain, greyish-brown fur, attaining the full adult colouration around eleven weeks of age. They begin to take solid food at six to seven weeks, when they begin to leave the den, but are not fully weaned for five or six months. The den

3016-476: Is marked with black spots; their number and pattern are highly variable. The underparts, neck and chin are whitish. The fur is more brightly coloured with more numerous spots in animals living at the southern end of its range. In winter, it is much thicker and varies from silver-grey to greyish brown. Some animals have dark brown stripes on the forehead and back. It has powerful, relatively long legs, with large webbed and furred paws that act like snowshoes. It also has

3120-622: Is possible that other Medieval and Modern era references to "wild cats" and "cats of the mountain", as late as the 18th century, actually refer to Eurasian lynx and not the Scottish wildcat as is commonly assumed. It has been proposed to reintroduce the lynx to the Scottish Highlands and Kielder Forest in Northumberland . A large lynx that hunted deer and livestock, sometimes called " tiger " and "deer's wolf" ( llobu /lobo cerval ),

3224-570: Is regulated in all three of its range countries, and is found in a number of protected areas of the United States , its principal territory. Estimates from the US Fish and Wildlife Service placed bobcat numbers between 700,000 and 1,500,000 in the US in 1988, with increased range and population density suggesting even greater numbers in subsequent years; for these reasons, the U.S. has petitioned CITES to remove

3328-453: Is scarce, or when deer populations become more abundant. One study in the Everglades showed a large majority of kills (33 of 39) were fawns . In Yellowstone a large number of kills (15 of 20) were elk calves, but prey up to eight times the bobcat's weight could be successfully taken. It stalks the deer, often when the deer is lying down, then rushes in and grabs it by the neck before biting

3432-513: Is seen on the lips, chin, and underparts. Bobcats in the desert regions of the southwest have the lightest-colored coats, while those in the northern, forested regions are darkest. Kittens are born well-furred and already have their spots. A few melanistic bobcats have been sighted and captured in Florida, USA and New Brunswick, Canada. They appear black, but may still exhibit a spot pattern. The face appears wide due to ruffs of extended hair beneath

The women's field hockey team won state championships in 2016, 2017, and 2018. In 2002, the Great Bridge High School Theatre Company placed first at the Virginia Theatre Association One-Act Competition, performing Gilgamesh: Man's First Story . The GBHS Theatre Company won again in 2005, performing The Standard of

3640-570: Is the preferred prey, and in Switzerland , chamois is locally favored. Eurasian lynx also feeds on carrion when available. Adult lynx require 1.1 to 2 kg (2.4 to 4.4 lb) of meat per day, and may take several days to fully consume some of their larger prey. In the Mediterranean mixed forest-steppe and subalpine ecosystems of Anatolia the main and most preferred prey of the Eurasian lynx

3744-626: Is thought to have evolved from the Eurasian lynx ( L. lynx ), which crossed into North America by way of the Bering Land Bridge during the Pleistocene , with progenitors arriving as early as 2.6 million years ago. It first appeared during the Irvingtonian stage around 1.8  million years ago . The first bobcat wave moved into the southern portion of North America, which was soon cut off from

3848-431: Is threatened by habitat loss and fragmentation , poaching and depletion of prey . Felis lynx was the scientific name used in 1758 by Carl Linnaeus in his work Systema Naturae . In the 19th and 20th centuries, the following Eurasian lynx subspecies were proposed: The following were also proposed, but are not considered valid taxa: The Eurasian lynx has a relatively short, reddish or brown coat that

3952-754: The Carpathian Mountains may rival those in the Altai in size. The Eurasian lynx inhabits rugged country providing plenty of hideouts and stalking opportunities. Depending on the locality, this may include rocky-steppe, mixed forest-steppe, boreal forest , and montane forest ecosystems. In the more mountainous parts of its range, Eurasian lynx descends to the lowlands in winter, following prey species and avoiding deep snow. Despite its adaptations for moving in snow, it finds loose, deep snow difficult to deal with and cannot survive in areas with snow depths exceeding 100 cm (39 in). It tends to be less common where

4056-621: The Catalonian Pyrenees , the last Eurasian lynx was killed in the 1930s, though unconfirmed sightings continued until the 1990s. The Síndic d'Aran planned a reintroduction in 2016 but canceled it due to the opposition of hunters and livestock farmers. In Germany , the Eurasian lynx was exterminated in 1850. It was reintroduced to the Bavarian Forest and the Harz in the 1990s; other areas were populated by lynxes migrating from France and

4160-508: The Chinese provinces of Xinjiang , Gansu , Qinghai , Sichuan , Shaanxi , and to the northern slopes of Iran 's Alborz Mountains and Mongolia . In northern Pakistan , the Eurasian lynx was recorded at elevations of 1,067–5,000 m (3,501–16,404 ft) in Chitral District . In India : Ladakh , Himachal Pradesh and most other Himalayan states. In Nepal , a Eurasian lynx

4264-623: The Czech Republic . In 2002, the first birth of wild lynx on German territory was announced, following a litter from a pair of lynx in the Harz National Park . Small populations exist also in Saxon Switzerland , Palatinate Forest , and Fichtel Mountains . Eurasian lynx also migrated to Austria , where they had also been exterminated. An episode of the PBS television series Nature featured

4368-504: The Nez Perce , for instance, depicts the bobcat and coyote as opposed, antithetical beings. However, another version represents them with equality and identicality. Claude Lévi-Strauss argues that the former concept, that of twins representing opposites, is an inherent theme in New World mythologies, but that they are not equally balanced figures, representing an open-ended dualism rather than

4472-519: The grey wolf ( Canis lupus ) is abundant, and wolves have been reported to attack and even eat lynx. The Eurasian lynx was once widespread throughout most of continental Europe. By the early 19th century, it was persecuted to local extinction in western and southern European lowlands, but survived only in mountainous areas and Scandinavian forests. By the 1950s, it had become extinct in most of Western and Central Europe , where only scattered and isolated populations exist today. The Eurasian lynx

4576-619: The 19th and 20th centuries, the following zoological specimens were described: The validity of these subspecies was challenged in 1981 because of the minor differences between specimens from the various geographic regions in North America. Since the revision of cat taxonomy in 2017, only two subspecies are recognized as valid taxa : The genus Lynx shares a clade with the genera Puma , Prionailurus and Felis dated to 7.15  million years ago ; Lynx diverged approximately 3.24  million years ago . The bobcat

4680-550: The Americas also admired the cat, both for its ferocity and its grace, and in the United States, it "rests prominently in the anthology of ... national folklore." Grave artifacts from dirt domes excavated in the 1980s along the Illinois River revealed a complete skeleton of a young bobcat along with a collar made of bone pendants and shell beads that had been buried by the Hopewell culture . The type and place of burial indicate

4784-604: The Bobcat . Eurasian lynx The Eurasian lynx ( Lynx lynx ) is one of the four extant species within the medium-sized wild cat genus Lynx . It is widely distributed from Northern , Central and Eastern Europe to Central Asia and Siberia , the Tibetan Plateau and the Himalayas . It inhabits temperate and boreal forests up to an elevation of 5,500 m (18,000 ft). Despite its wide distribution, it

4888-428: The Eurasian lynx is the only lynx species to preferentially take ungulates. Although taking on larger prey presents a risk to the Eurasian lynx, the bounty provided by killing them can outweigh the risks. The Eurasian lynx thus prefers fairly large ungulate prey, especially during winter, when small prey is less abundant. Where common, roe deer appear to be the preferred prey species for the Eurasian lynx. In Estonia,

4992-470: The Eurasian lynx lasts from January to April. The female typically comes into oestrus only once during this period, lasting from four to seven days. If the first litter is lost, a second period of oestrus is common. It does not appear to be able to control its reproductive behaviour based on prey availability. Gestation lasts from 67 to 74 days. Pregnant females construct dens in secluded locations, often protected by overhanging branches or tree roots. The den

5096-465: The Everglades by 87.5% has been attributed to predation by the invasive Burmese python . The bobcat has long been valued both for fur and sport; it has been hunted and trapped by humans, but has maintained a high population, even in the southern United States, where it is extensively hunted. In the 1970s and 1980s, an unprecedented rise in price for bobcat fur caused further interest in hunting, but by

5200-592: The Iberian lynx in Mediterranean forests, woodlands, and scrub . The Eurasian lynx of Spain was a unique, extinct lineage more related to the Carpathian and Baltic subspecies. It was genetically impoverished already in pre-Roman times, possibly because of founder effect , which made it even more vulnerable to human persecution. The government of Asturias studied the feasibility of Eurasian lynx reintroduction in 2019. In

5304-803: The Man . Bobcat See text The bobcat ( Lynx rufus ), also known as the wildcat , bay lynx , or red lynx , is one of the four extant species within the medium-sized wild cat genus Lynx . Native to North America , it ranges from southern Canada through most of the contiguous United States to Oaxaca in Mexico . It is listed as Least Concern on the IUCN Red List since 2002, due to its wide distribution and large population. Although it has been hunted extensively both for sport and fur, populations have proven stable, though declining in some areas. It has distinctive black bars on its forelegs and

5408-430: The activity of their prey, which are more active during the day in colder weather. Bobcat activities are confined to well-defined territories, which vary in size depending on the sex and the distribution of prey. The home range is marked with feces, urine scent , and by clawing prominent trees in the area. In its territory, the bobcat has numerous places of shelter, usually a main den, and several auxiliary shelters on

5512-412: The aridification of the region. The bobcat resembles other species of the midsize genus Lynx , but is on average the smallest of the four. Its coat is variable, though generally tan to grayish-brown, with black streaks on the body and dark bars on the forelegs and tail. Its spotted patterning acts as camouflage. The ears are black-tipped and pointed, with short, black tufts. Generally, an off-white color

5616-589: The average is about 45 mm ( 1 + 3 ⁄ 4  in). When walking or trotting, the tracks are spaced roughly 20 to 45 cm (8 to 18 in) apart. The bobcat can make great strides when running, often from 1.2–2.4 m (4–8 ft). Like all cats, the bobcat 'directly registers', meaning its hind prints usually fall exactly on top of its fore prints. Bobcat tracks can be generally distinguished from feral or house cat tracks by their larger size: about 15 cm (2 sq in) versus 10 cm ( 1 + 1 ⁄ 2  sq in). The bobcat

5720-474: The bobcat prefers rabbits and hares , it hunts insects , chickens , geese and other birds , small rodents , and deer . Prey selection depends on location and habitat , season, and abundance. Like most cats, the bobcat is territorial and largely solitary, although with some overlap in home ranges. It uses several methods to mark its territorial boundaries , including claw marks and deposits of urine or feces. The bobcat breeds from winter into spring and has

5824-601: The bobcat. Parasites' and diseases' role in the mortality of the bobcat is still unclear, but they may account for greater mortality than starvation, accidents, and predation. It is listed in Appendix II of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), which means it is not considered threatened with extinction, but that international trade must be closely monitored. The animal

5928-716: The cat from Appendix II. Populations in Canada and Mexico remain stable and healthy. It is listed as least concern on the IUCN Red List , noting it is relatively widespread and abundant, but information from southern Mexico is poor. The species is considered endangered in Ohio, Indiana, and New Jersey. It was removed from the threatened list of Illinois in 1999 and of Iowa in 2003. In Pennsylvania, limited hunting and trapping are once again allowed, after having been banned from 1970 to 1999. The bobcat also suffered population decline in New Jersey at

6032-458: The competition becomes especially fierce; the lynx is at a disadvantage as its competitors are able to capture additional, larger prey animals, and more efficiently. This competition may be especially severe in the northern parts of the lynx's range, where lynx populations are vastly outnumbered by red fox and even by wolverine. The presence of other large carnivores is one factor limiting their population. In two ecosystems of Anatolia, cannibalism

6136-600: The connectivity of different populations is affected. This leads to a decrease in natural genetic diversity among bobcat populations. For bobcats, preserving open space in sufficient quantities and quality is necessary for population viability. Educating local residents about the animals is critical, as well, for conservation in urban areas. In bobcats using urban habitats in California, the use of rodenticides has been linked to both secondary poisoning by consuming poisoned rats and mice, and to increased rates of severe mite infestation (known as notoedric mange ), as an animal with

6240-408: The contiguous 48 except Delaware. The bobcat population in Canada is limited due to both snow depth and the presence of the Canada lynx. The bobcat does not tolerate deep snow, and waits out heavy storms in sheltered areas; it lacks the large, padded feet of the Canada lynx and cannot support its weight on snow as efficiently. The bobcat is not entirely at a disadvantage where its range meets that of

6344-413: The country. The bobcat is crepuscular , and is active mostly during twilight. It keeps on the move from three hours before sunset until about midnight, and then again from before dawn until three hours after sunrise. Each night, it moves from 3 to 11 km (2 to 7 mi) along its habitual route. This behavior may vary seasonally, as bobcats become more diurnal during fall and winter in response to

SECTION 60

6448-463: The early 1990s, prices had dropped significantly. Regulated hunting still continues, with half of mortality of some populations being attributed to this cause. As a result, the rate of bobcat deaths is skewed in winter, when hunting season is generally open. Urbanization can result in the fragmentation of contiguous natural landscapes into patchy habitat within an urban area. Animals that live in these fragmented areas often have reduced movement between

6552-433: The ears. Bobcat eyes are yellow with round, black pupils. The nose of the bobcat is pinkish-red, and it has a base color of gray or yellowish- or brownish-red on its face, sides, and back. The pupils widen during nocturnal activity to maximize light reception. The bobcat has sharp hearing and vision, and a good sense of smell. It is an excellent climber and swims when it needs to, but normally avoids water. The adult bobcat

6656-558: The eastern United States found a divergence in the location of the largest male and female specimens, suggesting differing selection constraints for the sexes. Skeletal muscles make up 58.5 % of the bobcat's body weight. At birth, it weighs 270–340 g ( 9 + 1 ⁄ 2 –12 oz) and is about 25 cm (10 in) in length. At the age of one year, it weighs about 4.5 kg (10 lb). Bobcat tracks show four toes without claw marks, due to their retractile claws. The tracks range in size from 25–75 mm (1–3 in);

6760-517: The female. Eurasian lynx are secretive, and because the sounds they make are very quiet and seldom heard, their presence in an area may go unnoticed for years. Remnants of prey or tracks on snow are usually observed long before the animal is seen. The Eurasian lynx is an ambush predator but also hunts by stalking, sneaking and jumping on prey using both vision and hearing. When snow conditions make this harder, it may be forced to switch to larger prey. It often climbs onto high rocks or fallen trees to scan

6864-433: The former often being left in prominent locations along the boundary of the hunting territory. Eurasian lynx makes a range of vocalizations, but is generally silent outside of the breeding season. They have been observed to mew, hiss, growl, and purr, and, like domestic cats , will "chatter" at prey that is just out of reach. Mating calls are much louder, consisting of deep growls in the male, and loud "meow-like" sounds in

6968-419: The habitat patches, which can lead to reduced gene flow and pathogen transmission between patches. Animals such as the bobcat are particularly sensitive to fragmentation because of their large home ranges. A study in coastal Southern California has shown bobcat populations are affected by urbanization, creation of roads, and other developments. The populations may not be declining as much as predicted, but instead

7072-479: The larger felid: displacement of the Canada lynx by the aggressive bobcat has been observed where they interact in Nova Scotia , while the clearing of coniferous forests for agriculture has led to a northward retreat of the Canada lynx's range to the advantage of the bobcat. In northern and central Mexico, the cat is found in dry scrubland and forests of pine and oak; its range ends at the tropical southern portion of

7176-465: The largest males. Weights of both sexes in Russia range from 12 to 32 kg (26 to 71 lb), but more than 30 kg (66 lb) is attained very rarely and is possibly exaggerated. A Eurasian lynx from the Altai Mountains weighed 35 kg (77 lb). Those inhabiting Fennoscandia and westwards are considerably smaller, with a range of just 7–26 kg (15–57 lb), though individuals in

7280-637: The late 1970s onwards. In Italy , it recolonised the Italian Alps since the 1980s, also from reintroduced populations in Switzerland, Austria and Slovenia. By 2010, the Alpine lynx population comprised about 120–150 individuals ranging over 27,800 km (10,700 sq mi) in six sub-areas. In the Netherlands , lynxes have been sighted sporadically since 1985 in the country's southern part. Since 2020,

7384-517: The local availability of prey. Males tend to hunt over much larger areas than females, which tend to occupy exclusive, rather than overlapping, hunting ranges. The Eurasian lynx can travel up to 20 km (12 mi) during one night, although about half this distance is more typical. They patrol regularly throughout all parts of their hunting range, using scent marks to indicate their presence to other individuals. As with other cats, its scent marks may consist of faeces , urine , or scrape marks, with

7488-429: The more social inclination of the canid giving them a possible competitive advantage. With the Canada lynx, however, the interspecific relationship affects distribution patterns; competitive exclusion by the bobcat is likely to have prevented any further southward expansion of the range of its felid relative. The average lifespan of the bobcat is seven years but rarely exceeds 10 years. The oldest wild bobcat on record

7592-463: The more specialized Canada lynx, readily varies its prey selection. Diet diversification positively correlates to a decline in numbers of the bobcat's principal prey; the abundance of its main prey species is the main determinant of overall diet. The bobcat hunts animals of different sizes, and adjusts its hunting techniques accordingly. It hunts in areas abundant in prey and waits lying or crouching for victims to wander close. It then pounces and grabs

7696-522: The next spring. The adult bobcat has relatively few predators. However rarely, it may be killed in interspecific conflict by several larger predators or fall prey to them. Cougars and gray wolves can kill adult bobcats, a behavior repeatedly observed in Yellowstone National Park . Coyotes have killed adult bobcats and kittens. At least one confirmed observation of a bobcat and an American black bear (Ursus americanus) fighting over

7800-422: The north by glaciers ; the population evolved into the modern bobcat around 20,000 years ago. A second population arrived from Asia and settled in the north, developing into the modern Canada lynx ( L. canadensis ). Hybridization between the bobcat and the Canada lynx may sometimes occur. The populations east and west of the Great Plains were probably separated during Pleistocene interglacial periods due to

7904-493: The north, it is the snowshoe hare . When these prey species exist together, as in New England, they are the primary food sources of the bobcat. In the far south, the rabbits and hares are sometimes replaced by cotton rats as the primary food source. Birds up to the size of an adult trumpeter swan are also taken in ambushes while nesting, along with their fledglings and eggs. The bobcat is an opportunistic predator that, unlike

8008-567: The northern part of its range, the wolverine . In Russian forests, gray wolves kill and eat lynx that fail to escape into trees, as evidenced by examination of wolf and lynx trackways in the Central Forest Nature Reserve , and of lynx hair and bones found in wolf stomach contents in the Belovezh Forest . The lynx saves itself from its enemies by quickly climbing a tree or down the edge of a cliff or ravine; it usually lives near

8112-426: The other leading causes of death. Juveniles show high mortality shortly after leaving their mothers, while still perfecting their hunting techniques. One study of 15 bobcats showed yearly survival rates for both sexes averaged 0.62, in line with other research suggesting rates of 0.56 to 0.67. Cannibalism has been reported; kittens may be taken when prey levels are low, but this is very rare and does not much influence

8216-561: The outer extent of its range, such as hollow logs, brush piles, thickets, or under rock ledges. Its den smells strongly of the bobcat. The sizes of bobcats' home ranges vary significantly from 0.596–326 km (0.23–126 sq mi). One study in Kansas found resident males to have ranges of roughly 21 km (8 sq mi), and females less than half that area. Transient bobcats were found to have home ranges of 57 km (22 sq mi) and less well-defined home ranges. Kittens had

8320-699: The population has grown slowly but steadily. In 2019, around 250 lynx were reportedly living in Switzerland, roughly a third of them in the Jura Mountains, and the rest roaming the Alps and Pre-Alps. The Eurasian lynx was exterminated in the French Alps in the early 20th century. Following reintroduction of lynx in the Swiss Jura Mountains in the 1970s, lynxes were recorded again in the French Alps and Jura from

8424-403: The population of its prey; other principal factors in the selection of habitat type include protection from severe weather, availability of resting and den sites, dense cover for hunting and escape, and freedom from disturbance. The bobcat's range does not seem to be limited by human populations, but by availability of suitable habitat; only large, intensively cultivated tracts are unsuitable for

8528-434: The population. The bobcat may have external parasites , mostly ticks and fleas, and often carries the parasites of its prey, especially those of rabbits and squirrels. Internal parasites (endoparasites) are especially common in bobcats. One study found an average infection rate of 52% from Toxoplasma gondii , but with great regional variation. One mite in particular, Lynxacarus morlani , has to date been found only on

8632-410: The predators described above, and also with the red fox , eagle owls , golden eagles , wild boar (which scavenge from lynx kills), and in the southern part of its range, the snow leopard and leopard as well. Brown bears , although not (so far as is known) a predator of Eurasian lynx, are in some areas a semi-habitual usurpers of ungulate kills by lynxes, not infrequently before the cat has had

8736-777: The presence of lynxes has been confirmed by camera trapping in the Ardennes region in southern Belgium , proving the presence of the species following more than 25 years of unconfirmed sightings in the region. In the Anatolian part of Turkey , the Eurasian lynx is present in the Lesser Caucasus , Kaçkar Mountains and Artvin Province . In Ciglikara Nature Reserve located in the Taurus Mountains , 15 individuals were identified. More than 50 individuals were identified and monitored at

8840-747: The prey with its sharp, retractable claws. For slightly larger animals, such as geese, ducks, rabbits and hares, it stalks from cover and waits until prey comes within 6 to 11 m (20 to 35 ft) before rushing in to attack. Less commonly, it feeds on larger animals, such as young ungulates , and other carnivores, such as primarily female fishers , gray foxes , American minks , American martens , skunks , raccoons , small dogs and domestic cats . It also hunts rodents such as squirrels , moles , muskrats , mice , but also birds , small sharks , and insects . Bobcats occasional hunt livestock and poultry . While larger species, such as cattle and horses , are not known to be attacked, bobcats do present

8944-437: The rabbit in a tree, the bobcat is persuaded to build a fire, only to have the embers scattered on its fur, leaving it singed with dark brown spots. The Mohave people believed dreaming habitually of beings or objects would afford them their characteristics as supernatural powers. Dreaming of two deities, cougar and lynx, they thought, would grant them the superior hunting skills of other tribes. European-descended inhabitants of

9048-524: The result of carrion consumption. Occasionally, in areas such as Manchuria and the Amur River , it may be possible the Amur leopard targets lynx; in the same geographic region, Siberian tigers have also preyed on lynxes, as evidenced by examination of tiger stomach contents. In Sweden , out of 33 deaths of lynx of a population being observed, one was probably killed by a wolverine. Lynx compete for food with

9152-505: The return of the lynx to Austria's Kalkalpen National Park after a 150-year absence. A higher proportion is killed by humans than by infectious diseases. In Switzerland , the Eurasian lynx was exterminated in the early 20th century, with the last confirmed sighting around Simplon pass in 1904. From 1971 on, Carpathian lynx were reintroduced in the Alps and the Jura Mountains . Since then,

9256-540: The smallest range at about 8 km (3 sq mi). Dispersal from the natal range is most pronounced with males. Reports on seasonal variation in range size have been equivocal. One study found a large variation in male range sizes, from 41 km (16 sq mi) in summer up to 104 km (40 sq mi) in winter. Another found that female bobcats, especially those which were reproductively active, expanded their home range in winter, but that males merely shifted their range without expanding it, which

9360-454: The species. The animal may appear in back yards in "urban edge" environments, where human development intersects with natural habitats. If chased by a dog, it usually climbs up a tree. The historical range of the bobcat was from southern Canada, throughout the United States, and as far south as the Mexican state of Oaxaca , and it still persists across much of this area. In the 20th century, it

9464-546: The surrounding area. It is a powerful predator that has killed adult deer weighing at least 150 kg (330 lb). Eurasian lynx in Europe prey largely on small to fairly large sized mammals and birds. Among the recorded prey items for the species are hares , rabbits , marmots , squirrels , dormice , muskrats , martens , grouse , red foxes , wild boar , chamois , young moose , European roe deer , red deer , reindeer and other ungulates. In keeping with its larger size,

9568-486: The symmetric duality of Old World cultures. The latter notion then, Lévi-Strauss suggests, is the result of regular contact between Europeans and native cultures. Additionally, the version found in the Nez Perce story is of much greater complexity, while the version of equality seems to have lost the tale's original meaning. In a Shawnee tale, the bobcat is outwitted by a rabbit, which gives rise to its spots. After trapping

9672-680: The throat , base of the skull, or chest. On the rare occasions a bobcat kills a deer, it eats its fill and then buries the carcass under snow or leaves, often returning to it several times to feed. The bobcat prey base overlaps with that of other midsized predators of a similar ecological niche . Research in Maine has shown little evidence of competitive relationships between the bobcat and coyote or red fox ; separation distances and territory overlap appeared random among simultaneously monitored animals. However, other studies have found bobcat populations may decrease in areas with high coyote populations, with

9776-473: The turn of the 19th century, mainly because of commercial and agricultural developments causing habitat fragmentation ; by 1972, the bobcat was given full legal protection, and was listed as endangered in the state in 1991. The Mexican bobcat L. r. escuinipae was for a time considered endangered by the US Fish and Wildlife Service, but was delisted in 2005. Between 2003 and 2011, a reduction in bobcat sightings in

9880-499: Was 16 years old, and the oldest captive bobcat lived to be 32. Bobcats generally begin breeding by their second summer, though females may start as early as their first year. Sperm production begins each year by September or October, and the male is fertile into the summer. A dominant male travels with a female and mates with her several times, generally from winter until early spring; this varies by location, but most mating takes place during February and March. The pair may undertake

9984-617: Was also reported in Green Spain until the 19th century. These accounts were traditionally regarded as references to Iberian lynx ( Lynx pardinus ), a smaller endemic species of the Iberian Peninsula . However, genetic testing of remains showed that the Eurasian and Iberian lynx coexisted into recent times in the Iberian Peninsula with little overlap , the Eurasian lynx being present in temperate broadleaf and mixed forests and

10088-467: Was close to extinction in Scandinavia in the 1930s. Since the 1950s, the population slowly recovered and forms three subpopulations in northern, central and southern Scandinavia. In Norway , the Eurasian lynx was subjected to an official bounty between 1846 and 1980 and could be hunted without license. In 1994, a compensation scheme for livestock killed by lynx was introduced. By 1996, the lynx population

10192-473: Was common, and fellow lynx were found to form 5% to 8% of prey biomass in their diets. Claws and bones analysed showed that sub-adult lynx were the victims of cannibalism during the mating and spring seasons. Lynx were not found in the sympatrically occurring wolves' diets. On the contrary, lynx themselves were the predators of red fox, pine marten , domestic and feral cats and dogs, and golden jackal remains have also been found in lynx fecal samples, possibly

10296-444: Was consistent with numerous earlier studies. Other research in various American states has shown little or no seasonal variation. Like most felines, the bobcat is largely solitary, but ranges often overlap. Unusual for cats, males are more tolerant of overlap, while females rarely wander into others' ranges. Given their smaller range sizes, two or more females may reside within a male's home range. When multiple territories overlap,

10400-516: Was estimated to comprise 410 Individuals, decreased to less than 260 individuals in 2004 and increased since 2005 to about 452 mature individuals by 2008. In Sweden , the lynx population was estimated at 1,400 individuals in 2006 and 1,250 in 2011. Hunting is controlled by government agencies. In Finland , about 2,200–2,300 individuals were present according to a 2009 estimate. The lynx population in Finland has been increasing every year since 1991, and

10504-521: Was found. In the Pechora-Ilych Nature Reserve in Russia , wolverine predation and consumption of lynx has been documented, and in the Altai Mountains , the lynx actively avoids wolverines. The gray wolf, wolverine, as well as the red fox and the eagle owl , are also competitors with the Eurasian lynx for prey, notably in the taiga regions of Russia . In years of low hare populations,

10608-532: Was probably extirpated from the Japanese archipelago during the Jōmon period . Although they may hunt during the day when food is scarce, the Eurasian lynx is mainly nocturnal or crepuscular , and spends the day sleeping in dense thickets or other places of concealment. It lives solitarily as an adult. The hunting area of Eurasian lynx can be anything from 20 to 450 km (7.7 to 173.7 sq mi), depending on

10712-631: Was sighted in the western Dhaulagiri massif in 1975. It is also present above elevations of 3,800 m (12,500 ft) in Humla , Mustang and Dolpa Districts . Fossils of the Eurasian or a closely related Lynx species from the Late Pleistocene era and onward were excavated at various locations in the Japanese archipelago . Since no archaeological evidence dated after the Yayoi period has been found, it

10816-608: Was thought to have lost territory in the US Midwest and parts of the Northeast, including southern Minnesota, eastern South Dakota, and much of Missouri, mostly due to habitat changes from modern agricultural practices. While thought to no longer exist in western New York and Pennsylvania, multiple confirmed sightings of bobcats (including dead specimens) have been recently reported in New York's Southern Tier and in central New York , and
