(females), adult males weigh on average 25% more than females. The American Badger’s body appears flat dorso-ventrally, with a flat head, and shorttail and limbs. The upperparts are grayish-white to yellowish-brown orsilvery black; the underparts are buffy. The feet are dark brown to black. Black patches are present on the face, cheeks, chin, and throat. A dorsal white stripe runs from the nose to the neck, and in some populations, to the rump. The claws on the forefeet are long and strong. There are four pairs of mammae. The skull is wedge-shaped, almost triangular. Dental formula: 13/3,C1/1,P3/3,M1/2=34

, 40% of stomach contents were mammals, 35% were of plant origin, 10% were birds, 10% were insects, and the remainder was mostly inorganic materials. American Badgers obtain most of their food by excavating the burrows of fossorial animals. If large prey is taken, such as a rabbit, the badger may dig a hole, carry in the prey, and remain below ground with it for several days. There are reports of American Badgers forming a “hunting partnership” with Coyotes. The Coyote apparently usesits keen sense of smell to locate burrowing rodents and the American Badger digs them up with its powerful claws. Both predators then share the proceeds. The techniques used by American Badgers when hunting Richardson’s Ground Squirrels (Spermophilus richardsonii) have been observed. They frequently hunted hibernating squirrels in the autumn, sometimes hunted infants in the spring, but rarely hunted active squirrels in the summer. They always captured hibernating and active squirrels underground, but sometimes intercepted fleeing squirrels aboveground. The most common hunting technique used was excavation of the burrow, but plugging of openings accounted for 5-23% of hunting actions. Plugging occurred predominantly in mid-June to late July, before most ground squirrels hibernated, and in late August to late October when juvenile males were active, but other squirrels were in hibernation. American Badgers usually used soil from around the tunnel opening or soil dragged

from a nearby mound to plug tunnels. Theykill ground squirrels with a single grasping bite directed dorsally or laterally to the thorax. The canines and third upper incisors generally only bruise the skin, without puncturing it, but cause extensive hemorrhaging in the thoracic cavity. Food items are sometimes buried and eaten later.

In the autumn, she shifted to an adjacent area of 52 ha and often reused dens. In the winter, she used a single den and traveled infrequently within an area of 2 ha.

Mating occurs in late July or August. Implantation ofthe fertilized eggs into the uterus is delayed until December—February, and births take place in late March or early April. The total gestation period is about seven months; actual embryonic development is about six weeks. Litter size is one to five, usually two. The young are born underground in a nest of dry grass. They are weaned at aboutsix weeks and disperse soon after. Some young females may mate in the first breeding season following birth, when they are about four months old; males wait until the following year.
