Cynomys is a genus of rodents that are commonly known as prairie dogs. Synonyms for cynomys include prairie marmots, buffalo rats, and barkers. These creatures are found in the grassland regions of North America and are highly social animals, living in large colonies or towns underground. Prairie dogs are known for their unique vocalizations, with different calls having different meanings, such as alerting others to the presence of predators or simply communicating with nearby neighbors. Although they are often viewed as pests, prairie dogs play an important role in their ecosystem, as their burrows provide shelter for other animals and help aerate the soil.
