Who are the top dogs intown? In the case of the Mexican prairie dog, it is the dominant males who rule their family groups. These groups form a colony, or "town," that covers about 18 square kilometers on average. Members of this southernmost prairie dog species spend their lives in close contact, whether foraging for grasses or sharing living quarters. When a bird of prey, coyote or badger appears, a lookout posted at the burrow entrance calls out and the colony rushes to safety underground. But when it comes to the dire threat of habitat loss, there is no such simple escape: some 80% of its habitat has already disappeared.
