Description
Prairie dogs (Cynomys) are burrowing rodents (not actually dogs) native to the grasslands of North America. There are five different species of prairie dogs: black-tailed, white-tailed, Gunnison, Utah, and Mexican prairie dogs. They are a type of ground squirrel. On average, these stout-bodied rodents will grow to be between 30–40 centimetres (12–16 in) long, including the short tail and weigh between 0.5–1.5 kilograms (1–3 lb). They are found in the United States, Canada, and Mexico. They will eat all sorts of vegetables and fruits.
The highly social prairie dogs live in large colonies or "towns" – collections of prairie dog families that can span hundreds of acres. Families usually consist of 1 male and 2 to 4 females living in a strict social hierarchy. Prairie dog pups reach sexual maturity at about 3 years of age, and after their third winter the dominant male in a given family will drive them away, forcing them to establish their own families on the edges of the colony. The dominant male will defend the family's borders against rival prairie dogs, and disputes are resolved by fighting. Prairie dogs are also aggressive against predators such as badgers and snakes. Prairie dogs are social animals, however, and often make social visits with each other, and greet each other with a sort of kiss.

Prairie dog tunnel systems help channel rainwater into the water table to prevent runoff and erosion, and can also serve to change the composition of the soil in a region by reversing soil compaction that can be a result of cattle grazing. The tunnels usually have several chambers. Tunnels can descend vertically as much as 5 metres (16 ft), and can extend laterally as much as 30 metres (98 ft). Prairie dogs line their burrows with grass to insulate them, and the earth excavated from the burrow is piled up in mounds around the burrow's entrance. The prairie dogs use these carefully maintained mounds as observation posts.

The prairie dog is well adapted to predators. Using its dichromatic color vision, it can detect predators from a far distance and then alert other prairie dogs to the danger with a special, high-pitched call. Con Slobodchikoff and others assert that prairie dogs use a sophisticated system of vocal communication to describe specific predators. Prairie dogs also trim the vegetation around their colonies, perhaps to remove any cover for predators. Their burrows generally contain several routes of escape.

The prairie dog is chiefly herbivorous, though it eats some insects. It feeds primarily on grasses and, in the fall, broadleaf forbs. Prairie dogs have 1-6 pups (babies) yearly, which are born blind and furless and need about 30 days of close nurturing from their mother.
Ecologists consider this rodent to be a keystone species. They are an important prey species, being the primary diet in prairie species such as the Black-footed Ferret, the Swift Fox, the Golden Eagle, the badger, and the Ferruginous Hawk. Other species, such as the Mountain Plover and the Burrowing Owl, also rely on prairie dog burrows for nesting areas. Even grazing species such as bison, pronghorn, and mule deer have shown a proclivity for grazing on the same land used by prairie dogs. It is believed that they prefer the vegetative conditions after prairie dogs have foraged through the area.

Nevertheless, prairie dogs are often identified as pests and exterminated from agricultural properties because they are capable of damaging crops, as they clear the immediate area around their burrows of most vegetation.

As a result, prairie dog habitat has been impacted by direct removal by ranchers and farmers as well as the more obvious encroachment of urban development which has greatly reduced their populations. The removal of prairie dogs "causes undesirable spread of brush" the costs of which to livestock range may outweigh the benefits of removal.[9] The largest remaining community comprises Black-tailed Prairie Dogs. In spite of human encroachment, prairie dogs have adapted, continuing to dig burrows in open areas of western cities. [link]

These charismatic, rabbit-sized rodents live on North America's prairies and open grasslands in only a fraction of their former numbers.

Prairie dogs live in underground burrows, extensive warrens of tunnels and chambers marked by many mounds of packed earth at their surface entrances. Burrows have defined nurseries, sleeping quarters, and even toilets. They also feature listening posts near exits, so animals can safely keep tabs on the movements of predators outside. Prairie dogs spend a lot of time building and rebuilding these dwellings. Other animals benefit from their labors. Burrows may be shared by snakes, burrowing owls, and even rare black-footed ferrets, which hunt prairie dogs in their own dwellings.

Family groups (a male, a few females, and their young) inhabit burrows and cooperate to share food, chase off other prairie dogs, and groom one another. These group members even greet one another with a prairie dog kiss or nuzzle! Young pups are very playful and can often been seen romping near their burrows.

Black-tailed prairie dogs, the best known of the five prairie dog species, live in larger communities called towns, which may contain many hundreds of animals. Typically they cover less than half a square mile (1.3 square kilometers), but historically they could be enormous. The largest recorded prairie dog town covered some 25,000 square miles (65,000 square kilometers). That Texas town was home to perhaps four hundred million prairie dogs!

Another prairie dog species, the white-tailed prairie dog, lives in the western mountains. These rodents do not gather in large towns but maintain more scattered burrows. All species hunker down in winter and burn the reserves of fat they have stored during more plentiful seasons. White-tails may hibernate for up to six months on their mountain plains, while their black-tailed cousins sometimes emerge to feed on especially warm days.

They communicate with loud cries. A warning cry, for example, will send a town's denizens hustling to their holes at the approach of a badger, coyote, or other predator. A second, "all-clear" call alerts the community when the danger has passed. [link]
