A burrow is a small, often underground tunnel or hole that animals create for shelter, nesting, or protection. Many creatures, such as rabbits, moles, and groundhogs, dig burrows to escape predators and harsh weather. These structures can vary in size and complexity, depending on the species and their needs. Burrows serve multiple purposes, including storing food and raising young. They can also provide a safe environment for animals to rest and sleep. Some burrows are simple, while others may have multiple chambers and entrances, showcasing the adaptability of the animals that create them.
