Badgers are medium-sized mammals belonging to the family Mustelidae, which also includes weasels, otters, and ferrets. They have a stocky body, short legs, and a distinctive face with white stripes. Badgers are primarily nocturnal and are known for their burrowing habits, creating extensive underground homes called setts. These animals are found in various habitats, including forests, grasslands, and urban areas across North America and Europe. Badgers are omnivorous, feeding on a diet that includes insects, small mammals, fruits, and roots. They play an important role in their ecosystems by aerating the soil and controlling pest populations.
