American badger

Description

American badger is a solitary, medium-sized, common but seldom seen, carnivorous mammal. They are 28″ to 34″ in length, including the tail, and weigh 11½ to 24¾ pounds. Males are significantly larger than females. Badgers rarely live more than 4 or 5 years in the wild, but may live 10 years or more in captivity.

The body is stocky, low to the ground, and somewhat flattened. The fur (pelage) on the upper parts is yellowish-gray to reddish-brown and long, especially long at the sides. The longer hairs (guard hairs) are banded, giving the pelage a grizzled appearance. A bold, white, upper-middle (middorsal) stripe runs from the nose, over the top of its head, and ends on the nape of the neck near the shoulders. It does not extend onto the back. The underparts are buffy. The belly is whitish. The tail is short, 4¼″ to 7½″ long, and bushy.

The head is broad, especially at the back. The neck, crown, and nose are dark brown or black. The cheeks are white with a large black spot in front of each ear. The chin and throat are whitish. The ears are low and are edged with white.

The legs are short and stocky. The feet are dark brown or black. The claws on the front feet are extremely long.

Common badger (Taxidea taxus taxus) is the largest of the four subspecies.

Jackson’s badger (Taxidea taxus jacksoni) is typically darker and smaller, 23½″to 29½″ in length and weighing 15½ to 24¼ pounds.

Sign

Similar Species

The low, flattish profile and white middorsal head stripe are diagnostic. There are no similar species in North America.

Habitat

Badgers are animals of open places, including meadows, prairies, pastures, croplands, and brushlands with little or no ground cover. Their spread into forested regions has closely followed the clearing of those forests to create pastures and cropland.

Ecology

Behavior

Badgers are active mostly at night but also often during the day, especially in early morning. They are solitary animals.

Badgers are good diggers. They are the only mammal that can dig out pocket gophers. They usually dig their own burrow but may enlarge one dug by another mammal. They spend the day, raise their young, and spend the winter in a burrow. The burrow may be up to 26′ long and up to 6¾′ deep.

Adults have a home range of usually about 1 square mile in which they may have up to 46 burrows. In the winter their home range is much smaller. They are mostly inactive in winter, emerging occasionally on warmer days. They do not hibernate but may enter into a temporary state of reduced metabolic activity (torpor) lasting several days to several weeks.

Lifespan

4 to 5 years

Life Cycle

Mating takes place in August and September. The female then digs a nest at the end of its burrow and lines it with grass. The developing fertilized eggs (blastocysts) do not implant in the uterus until February or March. A litter of 1 to 7, usually 3 or 4, is born in March to early April. The female cares for the young until late summer or early fall.

Food

Mostly ground squirrels and pocket gophers, but also voles, mice, reptiles (including rattlesnakes), amphibians, ground-nesting birds and their eggs, insects, and other invertebrates.
