Bobcat

Taxonomy and evolution

The bobcat's scientific name, Lynx rufus, has a complex taxonomic history with numerous proposed subspecies since its first description as Felis rufa by Johann Christian Daniel von Schreber in 1777. Throughout the 19th and 20th centuries, various zoologists described specimens from different regions, leading to over a dozen proposed subspecies names based on minor morphological differences. These included Lynx floridanus from Florida in 1817, Lynx fasciatus from the northwest coast also in 1817, and Lynx baileyi from the San Francisco Mountains in 1890. Canadian relevant descriptions included Lynx gigas proposed by Outram Bangs in 1897 from a skin of an adult male shot near Bear River, Nova Scotia, and Lynx rufus superiorensis proposed by Randolph Lee Peterson and Stuart C. Downing in 1952 from a specimen killed near Port Arthur, Ontario. A major revision in 1981 challenged the validity of most of these subspecies due to the minimal variations between bobcats across North America. The current taxonomy, revised in 2017, recognizes only two valid subspecies, one east and one west of the Great Plains, likely separated during Pleistocene interglacial periods due to aridification.

The bobcat is thought to have evolved from the Eurasian lynx (Lynx lynx), which crossed into North America via the Bering Land Bridge during the Pleistocene epoch. The genus Lynx shares a clade with the genera Puma, Prionailurus and Felis dated to 7.15 million years ago, with Lynx diverging approximately 3.24 million years ago. The first bobcat wave moved into the southern portion of North America as early as 2.6 million years ago, with the modern bobcat form emerging around 20,000 years ago. A second population arrived from Asia and settled in the north, developing into the modern Canada lynx (Lynx canadensis). Hybridization between the bobcat and the Canada lynx may sometimes occur where their ranges overlap, though competitive exclusion by the bobcat is believed to have prevented further southward expansion of the Canada lynx's range.

Physical description

The bobcat is the smallest of the four Lynx species, with a variable coat colour generally ranging from tan to greyish brown. Its most distinguishing features are the black streaks on its body, dark bars on its forelegs and stubby tail, and pointed ears with short black tufts. The spotted patterning provides excellent camouflage in its woodland habitats. Bobcats exhibit clinal variation in colour, with the lightest coats found in southwestern desert regions and the darkest in northern forested areas like Canada and New England. Rare melanistic, or black, bobcats have been documented in Florida and New Brunswick, which appear black but may still show a faint spot pattern. The animal has a wide face due to hair ruffs below the ears, yellow eyes with black slit pupils that widen at night, and a pinkish red nose. Its sense of hearing and vision are sharp, and it has a good sense of smell. It is an excellent climber and will swim if necessary, though it normally avoids water.

Adult bobcats measure 47.5 to 125 cm from head to tail base, averaging 82.7 cm, with the distinctive 'bobbed' tail adding only 9 to 20 cm. They stand 30 to 60 cm at the shoulder. Adult males can range from 6.4 to 18.3 kg, averaging 9.6 kg, while females range from 4 to 15.3 kg, averaging 6.8 kg. The largest bobcat accurately measured on record weighed 22.2 kg, although unverified reports exist of animals reaching 27 kg, including a roadkill specimen reported in New Hampshire in 2012. Consistent with Bergmann's rule, the bobcat is larger in its northern range and in open habitats. The largest bodied bobcats were recorded in eastern Canada and northern New England, and the smallest in the southern Appalachian Mountains. Skeletal muscles make up 58.5 percent of the bobcat's body weight. At birth, kittens weigh 270 to 340 grams and are about 25 cm in length, growing to about 4.5 kg by one year of age.

Bobcat tracks show four toes without claw marks, due to their retractile claws. The tracks range in size from 25 to 75 mm, with the average being about 45 mm. When walking or trotting, the tracks are spaced roughly 20 to 45 cm apart. The bobcat can make great strides when running, often from 1.2 to 2.4 m. 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 square centimetres versus 10 square centimetres.

Distribution and habitat in Canada

The bobcat's historical range extends from southern Canada throughout the United States to Oaxaca, Mexico, and it persists across much of this area. In Canada, its population is limited primarily by deep snow, as it lacks the large, snowshoe-like paws of the Canada lynx and cannot efficiently travel or hunt in deep snowpack, waiting out heavy storms in sheltered areas. Its distribution is also influenced by the presence of the Canada lynx, with which it shares a complex competitive relationship. While the bobcat may be displaced by the larger felid in some areas, the clearing of coniferous forests for agriculture has facilitated a northward expansion of the bobcat's range and a corresponding retreat of the Canada lynx in some regions. Notably, displacement of the Canada lynx by the more aggressive bobcat has been observed in areas of interaction like Nova Scotia.

The bobcat is an extremely adaptable species that inhabits deciduous, coniferous, or mixed woodlands, semidesert, urban edge, forest edge, and swampland environments. 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, and its spotted coat serves as camouflage. The bobcat's range does not seem to be limited by human populations but by the availability of suitable habitat, with only large, intensively cultivated tracts being unsuitable. It can appear in backyards in urban edge environments and will climb a tree when chased by a dog. Population density depends heavily on prey availability and protection from severe weather, with estimates ranging widely from one to 38 bobcats per 26 square kilometres, averaging about one bobcat per 13 square kilometres.

• Its range in Canada is primarily in the southern regions, limited by snow depth and the presence of the Canada lynx.
• It does not depend exclusively on deep forest and can live near agricultural areas if cover like rocky ledges or forested tracts exists.
• Populations are vulnerable to local extirpation by coyotes and domestic animals.
• It has been observed in provinces including Ontario, Nova Scotia, and New Brunswick, with the subspecies Lynx gigas described from Nova Scotia.
• The cat waits out heavy storms in sheltered areas due to its poor snow tolerance.
• In northern and central Mexico, its range includes dry scrubland and pine and oak forests, ending in the tropical south.

Behaviour and ecology

The bobcat is primarily crepuscular, most active during twilight hours from three hours before sunset to midnight and again from before dawn until three hours after sunrise. Each night, it moves from 3 to 11 kilometres along its habitual route. This behaviour may vary seasonally, as bobcats become more diurnal during fall and winter in response to the activity of their prey, which are more active during the day in colder weather. Bobcats are largely solitary and territorial, with home ranges marked by feces, urine scent, and claw marks on prominent trees. Territories contain a main den, which smells strongly of the bobcat, and several auxiliary shelters on the outer extent of its range, such as hollow logs, brush piles, thickets, or under rock ledges.

Home range sizes vary dramatically from 0.596 to 326 square kilometres, influenced by sex and prey distribution. One study in Kansas found resident males had ranges of roughly 21 square kilometres, and females less than half that area. Transient bobcats had home ranges of 57 square kilometres and less well defined boundaries. Kittens had the smallest range at about 8 square kilometres. Reports on seasonal variation are equivocal, with one study finding male ranges from 41 square kilometres in summer to 104 square kilometres in winter, while another found females expanded their range in winter but males merely shifted theirs. Unusually for cats, males are more tolerant of range overlap than females, and a dominance hierarchy is established where territories overlap, resulting in the exclusion of some transients from favoured areas. Population density figures diverge, and a link has been observed between density and sex ratio, with an unhunted California population having a sex ratio of 2.1 males per female, skewing to 0.86 males per female when density decreased.

Hunting and diet

The bobcat is an opportunistic and adaptable predator capable of surviving long periods without food, but it eats heavily when prey is abundant. During lean periods, it often preys on larger animals, which it can kill and return to feed on later. It hunts by stalking its prey and then ambushing with a short chase or pounce. Its preference is for mammals weighing about 0.7 to 6 kilograms. Its main prey varies by region, with the eastern cottontail and New England cottontail being primary in the eastern United States and the snowshoe hare in the north. In the far south, cotton rats sometimes replace rabbits and hares as the primary food source. Diet diversification positively correlates with a decline in the numbers of the bobcat's principal prey, with the abundance of its main prey species being the main determinant of overall diet.

The bobcat hunts animals of different sizes and adjusts its techniques accordingly. For small prey, it waits lying or crouching for the animal to wander close before pouncing. For slightly larger animals like geese, ducks, rabbits, and hares, it stalks from cover and waits until prey comes within 6 to 11 metres before rushing in. Less commonly, it feeds on larger animals such as young ungulates, and other carnivores like fishers, foxes, minks, martens, skunks, raccoons, small dogs, and domestic cats. It is also known to take birds up to the size of an adult trumpeter swan, along with their eggs and fledglings. Bobcats occasionally hunt livestock and poultry, and according to the National Agricultural Statistics Service, they killed 11,100 sheep in 2004, comprising 4.9 percent of all sheep predator deaths, though some predation may be misidentified scavenging.

The bobcat has been known to kill deer or pronghorn, and sometimes hunts elk in western North America, especially in winter. 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 the throat, base of the skull, or chest. On the rare occasions it 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. Research in Maine has shown little evidence of competitive relationships with the coyote or red fox, but other studies suggest bobcat populations may decrease in areas with high coyote populations.

Reproduction and life cycle

Bobcats breed from winter into spring, with a gestation period of about two months. Females give birth to a litter of kittens in a secluded den, such as a hollow log, brush pile, thicket, or under a rock ledge. At birth, kittens weigh between 270 and 340 grams and are about 25 centimetres long, already well furred and spotted. They are weaned at around two months of age but may remain with their mother until the following spring. By one year of age, a bobcat typically weighs about 4.5 kilograms. Dispersal from the natal range is most pronounced with males, who establish their own territories, while females often have smaller ranges and may reside within a male's home range, with two or more females possible in one male's territory. The average lifespan of a bobcat in the wild is seven years, and it rarely exceeds ten years, though the oldest recorded wild bobcat lived to 16 years. Population density and sex ratios are linked, with one unhunted California population showing a 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, which may help limit reproduction until various factors lower the density. The bobcat's solitary nature is maintained through territorial marking and a social structure where ranges often overlap but a hierarchy is established.

Relationship with humans and conservation

The bobcat has a long history of interaction with humans, both as a species of cultural significance and as a hunted animal. It features in the stories of Indigenous peoples of North and Central America and in the folklore of European descended inhabitants of the Americas. It has been extensively hunted for sport and for its fur, which was historically a valuable commodity. Despite this pressure, bobcat populations have proven resilient and stable over much of their range, leading to its Least Concern status on the IUCN Red List since 2002. The primary conservation challenges are not overall population decline but local pressures from habitat fragmentation, agricultural changes, and interactions with other species.

In the 20th century, modern agricultural practices led to perceived range loss in parts of the US Midwest and Northeast, including southern Minnesota, eastern South Dakota, and much of Missouri. It was thought to no longer exist in western New York and Pennsylvania, but multiple confirmed sightings, including dead specimens, have been recently reported in New York's Southern Tier and central New York. A bobcat was captured in 2018 on a tourist boat in Downtown Pittsburgh, Pennsylvania. Sightings have also been confirmed in northern Indiana, and one was killed near Albion, Michigan, in 2008. In early March 2010, a bobcat was sighted and captured in a parking garage in Downtown Houston. By 2010, bobcats appear to have recolonized many states, occurring in every state in the contiguous 48 except Delaware.

In Canada, its range is stable but constrained by ecological factors like snow and competition with the Canada lynx. Bobcats occasionally come into conflict with humans by preying on small livestock and poultry. While larger species like cattle and horses are not known to be attacked, bobcats present a threat to smaller ruminants such as pigs, sheep, and goats. The bobcat's adaptability to human altered landscapes, including urban edge environments, ensures its continued presence across North America, though careful monitoring of local populations and habitats remains important. Its ability to thrive in varied habitats, from swamps to desert edges, and its generalist diet contribute to its overall stability as a species.

• Listed as Least Concern on IUCN Red List since 2002 due to wide distribution and large population.
• Historically hunted for sport and fur, but populations have proven stable.
• Range loss in 20th century in some US areas due to agricultural habitat changes.
• Recent recolonization and sightings in many parts of its historical US range, including urban areas.
• Conflict with humans primarily limited to occasional livestock predation.
• Cultural significance in Indigenous and settler folklore.
• Future persistence tied to maintenance of suitable habitat and prey bases.

Questions about Bobcat

Are there bobcats in Canada?

Yes, bobcats are native to southern Canada. Their range is limited primarily by deep snow, as they lack the large, padded feet of the Canada lynx and cannot travel efficiently in deep snowpack. They are found in regions such as Ontario, Nova Scotia, and New Brunswick. Their distribution is also influenced by the presence and competition with the Canada lynx, with interactions and even displacement of lynx by bobcats observed in areas like Nova Scotia. The clearing of coniferous forests has also aided a northward bobcat range expansion in some areas.

What is the difference between a bobcat and a Canada lynx?

The bobcat is smaller on average than the Canada lynx and has a shorter, more distinctly 'bobbed' tail with a black tip on the upper side. The Canada lynx has enormous, snowshoe-like paws for traversing deep snow, while the bobcat's feet are smaller and less suited for deep snow. The lynx is a specialist heavily reliant on snowshoe hares, whereas the bobcat is a generalist predator with a highly varied diet. Their ranges overlap in parts of Canada, and rare hybridization can occur. The bobcat is also more aggressive and has been observed displacing the Canada lynx in areas like Nova Scotia.

What do bobcats eat?

Bobcats are opportunistic predators with a diet that varies by region and season. They primarily hunt rabbits and hares, such as the eastern cottontail and snowshoe hare. Their diet also includes small rodents like squirrels and mice, birds ranging from ducks to large swans, and insects. In winter or when smaller prey is scarce, they may hunt larger animals like deer fawns or elk calves, with studies in Yellowstone showing they can take prey up to eight times their own weight. They occasionally prey on livestock such as sheep and poultry, and will also eat other carnivores like foxes or skunks.

How big do bobcats get?

Bobcats are the smallest of the four lynx species. Adult males average 9.6 kilograms in weight, with a range of 6.4 to 18.3 kg, and females average 6.8 kg, with a range of 4 to 15.3 kg. They measure 47.5 to 125 cm from head to the base of their tail, averaging 82.7 cm, with the tail adding 9 to 20 cm. They stand 30 to 60 cm at the shoulder. The largest verified bobcat on record weighed 22.2 kg, with the largest bodied individuals historically found in eastern Canada and northern New England, following Bergmann's rule where northern animals are larger.

Are bobcats dangerous to humans?

Bobcats are generally elusive, solitary, and avoid human contact. They are not considered a significant danger to people. Conflicts usually arise only if a bobcat is cornered, rabid, or has become habituated to humans through feeding. Their primary impact on human interests is occasional predation on small livestock and poultry. When encountered, they typically retreat, and they are known to climb trees to escape threats like dogs. There is no record of unprovoked fatal attacks on humans, and they play a valuable role in controlling rodent and rabbit populations.

What is the conservation status of the bobcat?

The bobcat is listed as Least Concern on the IUCN Red List, an assessment it has held since 2002. This status reflects its wide distribution across North America from southern Canada to Mexico and its generally large, stable population. Although it has been hunted extensively for fur and sport for centuries, populations have remained resilient due to its adaptability. Local pressures exist from habitat change, agricultural practices, and competition with species like coyotes, but the species has recolonized many parts of its historical range in the United States and remains common.
