In ecology, the bobcats' niche is defined by the available resources, competitors and predators in its environment. Digital-Desert explains that young bobcats are often killed by great horned owls, and adult bobcats are occasionally killed by mountain lions and dogs. Bobcats and coyotes compete. When coyote population numbers decline, bobcat population numbers increase, according to Digital-Desert.
According to National Geographic, bobcats have long legs, large paws and tufted ears. They are brown or brownish red with a white belly, and they have a short, black-tipped tail. Bobcats reach 17 to 23 inches in height. Males weigh 16 to 28 pounds, while females weigh 10 to 18 pounds. Bobcats have a lifespan of 12 to 13 years. They eat rodents, birds, bats, deer, lambs, poultry, pigs and rabbits, and they are found throughout most of North America.
Bobcats mate in late winter and give birth from 1 to 6 kittens in late spring. National Geographic states that the kittens stay with the mother for 9 to 12 months, during this time they learn to hunt. Female bobcats do not share territories, but male territories often overlap. The territories are marked by scents.
Defenders of Wildlife explains that bobcats may have several dens in their territories. The main den is usually a cave or rock shelter. The auxiliary den is located in an area that is not often visited, and it consists of a brush pile, rock ledge or stumps.
