The European badger has a powerfully built body, short tail, and short, solid limbs. The skull is heavy and large with a prominent sagittal crest and short, triangular paroccipital processes. Their teeth include prominent canines, flattened molars, and small incisors. The European badgers are easily recognizable due to dark stripes, stretching from their nose to the eyes and ears, and separated by a white stripe in the middle. The coat on their back is grizzled gray with individual hairs, being white at the base and darker at the tip. Venter coat is usually dark grey or black in color.
They are found throughout most of Europe as well as western Asia. The area of their distribution extends southward to the southeastern coast of China and northward, reaching the Russian Arctic Circle and Finland. They live in a wide variety of habitats such as scrub, hedges, riverine areas, farmland, grassland, steppes, and semi-deserts. However, their preferred habitat is a conifer, deciduous and mixed woodlands, adjacent to open fields.
The Eurasian badger is a nocturnal animal. The badgers are most active at sunrise and sunset. Badgers are highly social animals, gathering in clans - family groups that may include up to 12 individuals and only one dominant breeding pair. However, during periods of food shortage, some individuals, belonging to clans, isolate themselves, leading solitary life. Throughout the territory of each clan, there are multiple setts - large, communal burrows, constructed by members of the clan. The main sett is usually situated in the center of the clan's territory and contains more adult individuals, compared to other setts.
They are omnivores, consuming food of both plant and animal origin. The usual diet of the Eurasian badger includes fruit, earthworms, insects, frogs, lizards, eggs, small mammals as well as carrion.
European badgers don't have a certain mating system. Thus, male badgers are usually monogamous, mating once in a lifetime. However, female badgers can have polygamous behavior, mating with a number of males. Meanwhile, males do not restrict access of other males to their mates, but fiercely defend the mates from potential predators. They breed throughout the year with two peak seasons, occurring in February-May and August-October. The gestation period lasts 9-12 months, yielding 1-6 cubs with 3 on average. At the age of 2,5 months, the cubs are weaned and leave the den when they are about 8-10 months old. Reproductive maturity is reached at about 1 year of age.
Throughout their range, these animals are threatened by fragmentation and loss of habitat. They are persecuted due to being pest crops and disease vectors. In addition, the badgers are often hunted for sport and hit by cars.
According to IUCN, the European badger is common and widespread throughout its range but the total number of their population is unknown. However, in 1990, the estimated badger population in Russia was about 30,000 individuals. The population of this species is currently stable, and on the IUCN Red List, it is classified as Least Concern (LC).
The major part of their diet consists of invertebrates. Meanwhile, consuming insects, badgers control a large number of insect species' populations. On the other hand, due to eating fruit, they become important seed dispersers throughout the area of their range. According to one study, only a small percentage of seeds are damaged, when ingested by badgers.
