Prairie dog burrows are detailed with separate tunnels and areas built for specific purposes. These expansive underground dwellings have areas defined by the intended activities, such as nurseries, sleeping areas, and toilet areas. The burrows are home to groups known as coteries, which may consist of tens of thousands of prairie dogs. A typical prairie dog burrow may contain approximately 70 tunnel entrances, which are also built with clear purpose in mind—the prairie dogs set up posts for members of their packs to stand watch for predators and warn others in the pack. Prairie dogs may also rebuild their burrows as needed in order to update the design to better fit necessary activities.
