Bobcat by Bobbi Z
The bobcat (Lynx rufus) is a North American mammal of the cat family, Felidae. With twelve recognized subspecies, it ranges from southern Canada to northern Mexico, including most of the continental United States. The bobcat is an adaptable predator that inhabits wooded areas, as well as semi-desert, urban edge, forest edges and swampland environments. It persists in much of its original range and populations are healthy.
With a gray to brown coat, whiskered face, and black-tufted ears, the bobcat resembles the other species of the mid-sized Lynx genus. It is smaller than the Canadian Lynx, with which it shares parts of its range, but is about twice as large as the domestic cat. It has distinctive black bars on its forelegs and a black-tipped, stubby tail, from which it derives its name.
Though the bobcat prefers rabbits and hares, it will hunt anything from insects and small rodents to deer. Prey selection depends on location and habitat, season, and abundance. Like most cats, the bobcat is territorial and largely solitary, although there is 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 a gestation period of about two months.
Although the bobcat have been subject to extensive hunting by humans, both for sport and fur, its population has proven resilient. The elusive predator features in Native American mythology and the folklore of European settlers.
Physical characteristics
The Bobcat resembles other species of the Lynx genus 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. There is generally an off-white color 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. They appear black, but may actually still exhibit a spot pattern.
The face appears wide due to ruffs of extended hair beneath the ears. The fur is brittle but quite long and dense. 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. Bobcat eyes are yellow with black pupils. The pupils are elongated vertically and will widen during nocturnal activity to maximize light reception. The cat has sharp hearing and vision, and a good sense of smell. It is an excellent climber, and will swim when it needs to, but will normally avoid water.
The adult male Bobcat is 28 to 47 inches (70–120 cm) long, averaging 36 inches (90 cm); this includes a stubby 4 to 7 inch (10–18 cm) tail, which has a "bobbed" appearance and gives the species its name. An adult stands about 14 or 15 inches (36–38 cm) at the shoulders. Adult males usually range from 16 to 30 pounds (7–14 kg); females average about 20 pounds (9 kg). The Bobcat is muscular, and its hind legs are longer than its front legs, giving it a bobbing gait. At birth it weighs 0.6 to 0.75 pounds (280–340 g) and is about 10 inches (25 cm) in length. By its first year it will reach about 10 pounds (4.5 kg).
The cat is larger in its northern range and in open habitats. A morphological size comparison study in the eastern United States found a divergence in the location of the largest male and female specimens, suggesting differing selection constraints for the sexes.
Behavior
The Bobcat is crepuscular (generally most active at twilight and dawn). 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 will move from 2 to 7 miles (3–11 km) along its habitual route. This behavior may vary seasonally, as Bobcats become more diurnal during fall and winter. This is a response to the activity of their prey, which are more active during the day in colder months.
Social structure and home range
Bobcat activities are confined to well-defined territories, which vary in size depending on 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 will have numerous places of shelter: usually a main den, and several auxiliary shelters on 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 Bobcat home ranges vary significantly; a World Conservation Union (IUCN) summary of research suggests ranges anywhere from 0.02 to 126 sq mi (0.6 to 326 km²). One study in Kansas found resident males to have roughly an 8 sq mi (20 km²) range and females less than half that area. Transient Bobcats were found to have both a larger (roughly 22 sq mi/57 km2) and less well-defined home range. Kittens had the smallest range at about 3 sq mi (7 km²). Research has shown that 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 16 sq mi (41 km²) in summer up to 40 sq mi (100 km²) 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 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 will often overlap. Unusually for a cat, 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 male territories overlap 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 are divergent: anywhere from 1 to 38 Bobcats per 25 sq mi (65 km²) in one survey. The average is estimated at one Bobcat per every 5 sq mi (13 km²), or slightly less. A link has been observed between population density and sex ratio. One study noted that a dense, unharvested population in California had 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 that males may be better able to cope with the increased competition, and that this would help limit reproduction until various factors lowered the density.
Hunting and diet
The Bobcat is able to go for long periods without food, but will eat heavily when prey is abundant. During lean periods, it will often prey on larger animals that it can kill and return to feed on later. The Bobcat hunts by stalking its prey and then ambushing it with a short chase or pounce. Its preference is for mammals about 1.5 to 12.5 pounds (0.7 to 5.7 kg). Its main prey varies by region. In the eastern United States it is the Cottontail rabbit species, and in 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 hare are sometimes replaced by Cotton Rats as the primary food source. The Bobcat is an opportunistic predator that, unlike the more specialized Canadian Lynx, will readily vary its prey selection. Research has shown that 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 will adjust its hunting techniques accordingly. With small animals, such as rodents, squirrels, birds, fish and insects, it will hunt in areas known to be abundant in prey, and will lie, crouch, or stand and wait for victims to wander close. It will then pounce, grabbing its prey with its sharp, retractable claws. For slightly larger animals, such as rabbits and hares, it will stalk from cover and wait until they come within 20 to 35 feet (6 to 10 m) before rushing in to attack. Less commonly it will feed on larger animals such as foxes, minks, skunks, small dogs and house cats. Bobcats are also occasional hunters of livestock and poultry. While larger species such as cattle and horses are not known to be attacked, Bobcats do present a threat to smaller ruminants such as 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, especially in winter when smaller prey 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, but that prey up to eight times the Bobcat's weight could be successfully taken.[26] It stalks the deer, often when the deer is lying down, then rushes in and grabs it by the neck before biting through the throat, base of the skull, or chest. On the rare occasions that 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 mid-sized 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 amongst simultaneously monitored animals.With the Canadian 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 cousin.
