There are several predators in the Park, including bobcats, eagles, badgers, and cougars, but the coyotes are the most easily seen.
Most research has shown that coyotes usually feed on small mammals and birds. They do not feed heavily on livestock or larger ungulates, like elk, deer, or bison unless the animal is already dead or dying.
Little is known about the predatory behavior of wild coyotes, but a sudden hop or pounce is most often used for capturing small animals, like shrew or mice, where group effort may be used in the prairie dog towns. Coyotes depend on various senses to locate their prey, with sight, hearing, and smell being most important-usually in that order.
Coyotes are small mammals, about the size of a medium-sized dog. They vary widely in coloration, ranging from an almost pure gray to a red-brown. The fur is generally much thicker in winter-giving the animal a heavier appearance, with the summer coat being much shorter and lighter.
