Distribution

The bobcat formerly ranged from southern Canada throughout most of the United States south to central Mexico. It has been extirpated from densely settled areas and from much of the central portion of the United States.

Great Smoky Mountains National Park: The bobcat is a fairly common resident at all elevations throughout the park.

Habitat

Deciduous forests with much undergrowth and numerous clearings provide good habitat in the eastern United States. Bobcats also inhabit river bottom swamps.

Natural History

Reproduction
Most litters are born in April and May after a 50 to 70 day gestation. Litters usually consist of two to three kittens but may range from one to five. Little or no nest is provided for the young, which are born in a dry, well-hidden, and inaccessible den. Newborn kittens have a mottled coat, have their eyes closed, are about 250 mm long, and weigh up to 340 g. The eyes open in 9 to 10 days. The young nurse for approximately two months, after which their diet is composed of meat. The young disperse during the fall and winter.

Longevity
Average longevity in the wild is probably between six and eight years.

Terrestrial Ecology
The bobcat is rarely observed because of its solitary, mainly nocturnal habits. It is active during all seasons. It has excellent senses of sight, smell, and hearing and is an excellent climber. Shelters may be in a hollow log, inside a hollow snag, or in a thicket.

The main foods are rabbits and rodents. Hamilton (1943) remarked: "A few stomachs which I examined from the Smoky Mountains of North Carolina contained the remains of beetles, rabbits and a small box turtle." Examination of the stomach of an adult bobcat killed by a car on the Newfound Gap Road in Tennessee (3,700 feet) revealed eight shrews (Sorex sp.), six woodland jumping mice (Napaeozapus insignis), five rock voles (Microtus chrotorrhinus), one deermouse (Peromyscus sp.), and one small bird (Stupka, 1952). An individual found dead near Cliff Branch (2,600 feet) in December 1953, had eaten a gray squirrel (Sciurus carolinensis) (Stupka, 1953). A freshly killed, partially eaten woodchuck (Marmota monax) covered with leaves was found in January by Stupka above Big Cove (3,200 feet) near the park boundary. Many bobcat tracks were present in the snow nearby. A bobcat with a grouse in its mouth was observed on Clingmans Dome Road in 1990.

A statewide winter food habits study in North Carolina revealed rabbits, birds, cotton rats, white-tailed deer, small rodents, gray squirrels, raccoons, and opossums as the main food items by frequency of occurrence (King et al., 1983). Small numbers of reptiles, amphibians, fish, and insects were also identified.
Predators and Defense
Adult bobcats have relatively few enemies, although foxes and great horned owls may kill young.
Parasites
Bobcats taken by the Komareks were heavily infested with fleas (Komarek and Komerek, 1938).
