The bobcat, named for its short tail, occurs frequently in the southern half
of North America, but is rarely found in the Midwestern United States. They
are common in the mountains of the Carolinas, and also in the coastal plain
as far north as the Great Dismal Swamp. Larger populations occur in the mountains
and coastal plain than in the Piedmont region.
Bobcats are somewhat larger than domestic cats, ranging from twenty-four to
almost forty inches in length, including the tail. They weigh between 16 and
24 pounds, depending on their sex, with males typically being heavier than females.
Larger bobcats tend to occur in more open habitats, with smaller bobcats in
forested habitat. Bobcats are always spotted to some extent, with some individuals
patterned only on their undersides, and others with spots extending up their
sides and onto the chest and back. Their mottled coloration varies from grayish
to reddish-brown with small, darker spots and blotches. The tail is short and
tipped with black on the upper surface. Long hairs on their faces resemble "sideburns,"
and their ears are usually dark with a white patch near the tip.
Habits and Habitats
Bobcats are solitary hunters that prey mostly on small mammals such as rabbits
and rodents, although as generalists they will also eat birds and even large
animals like the white-tail deer. Bobcats have binocular vision, which enables
them to focus on swift running prey. In addition, their pupils expand to take
in all available light, making them extremely effective night hunters. Bobcats
may be active during all hours of the day and night; however, studies have consistently
found dawn and dusk activity peaks. This pattern is based on the activity patterns
of bobcats' prey species. Sharp claws that assist in climbing are retractable,
allowing the bobcat to approach their prey more quietly. They can stalk to within
a few feet of their intended prey and then make a short dash or pounce. Bobcats
have compact skulls (fewer teeth and shortened jaws) coupled with long canine
teeth. This provides them with tremendous biting pressure that can kill their
prey in one bite.
Bobcats begin breeding at one year of age, usually in late winter or early
spring. Two to four kittens are born after a gestation period of about sixty-two
days. The young are furred, but blind at birth. In about ten days, their eyes
will open and at four weeks they begin to explore the area around the den. After
seven or eight weeks, they are weaned.
Bobcats occupy a variety of habitats where there are dense thickets, including
coastal swamps and upland forests. Only large, intensively cultivated areas
and metropolitan areas appear to be unsuitable habitat. Although they are often
undetected, bobcats can live close to humans as long as there is suitable habitat.
Areas with dense understory vegetation and high prey densities are most intensively
selected by bobcats. They make their dens in hollow trees, small caves, and
underneath rock ledges and outcroppings.
History
Bobcats were once found throughout the United States, but today their range
is more limited. A major mortality factor appears to be the available food supply,
although parasites and diseases can also affect the bobcat population. Bobcats
have historically been less abundant in the east-central US, owing to high human
population density and intensive, large scale agriculture. The Southeastern
US and coastal California regions appear to support the greatest populations
of bobcats; reduced bobcat density is associated with harsher environments.
It is legal to hunt and trap bobcats in North Carolina during set seasons.
In 1988, 37 states and 5 Native American groups were authorized by the US government
to export bobcat pelts. The bobcat is totally protected in 10 states, while
hunting is regulated in 5 states and shooting of suspected livestock predators
is permitted on a limited basis. The price for bobcat pelts has recently risen,
and some wildlife biologists feel that increased trapping pressure could possibly
threaten bobcat populations in some areas. In the past 20 years, the bobcat
has been the most heavily harvested and traded member of the feline family.
