The Common Dormouse (*Muscardinus avellanarius*) is a small, nocturnal rodent found across Europe and parts of Asia. It has a round body, large eyes, and a bushy tail, typically measuring about 7 to 10 inches long. This species prefers habitats with dense vegetation, such as woodlands and hedgerows, where it can find its primary food sources, including nuts, fruits, and flowers. Common Dormice are known for their hibernation behavior, which lasts from late autumn to early spring. During this time, they enter a state of torpor to conserve energy. They build nests in tree hollows or dense shrubs, using leaves and grasses for insulation. Their population is affected by habitat loss and climate change, making conservation efforts important for their survival.
