Prairie dog

Description and Species

Prairie dogs are stout-bodied rodents with short tails, measuring between 28 and 43 centimetres in length and weighing from 0.5 to 1.5 kilograms. They typically have cinnamon-coloured fur, white bellies, and relatively large black eyes, with the black-tailed prairie dog, the species found in Canada, being tan with a whitish belly and a tail sparsely covered with black hair at the tip. There are five recognized species of prairie dog: the black-tailed, white-tailed, Gunnison's, Utah, and Mexican prairie dogs, which are distinguished by geographic range, physical characteristics like tail colour, and the degree of sexual dimorphism, which is most pronounced in white-tailed prairie dogs and varies between 105 to 136 percent in body mass between the sexes. The average lifespan of a prairie dog in the wild is 8 to 10 years, though survival rates are influenced by predation and environmental factors, with females in the wild living up to 8 years and males around 5 years, while in human care they can live over eight years.

The genus name, Cynomys, derives from the Greek for 'dog mouse'. The black-tailed prairie dog was first described by the Lewis and Clark Expedition in 1804. Lewis described it in more detail in 1806, calling it the 'barking squirrel'. The name wishtonwish was recorded by Lieutenant Zebulon Pike. In Lakota, the word is pispíza or pìspíza. Despite the name, a prairie dog skull has a condylobasal length of between 5.2 and 6.4 cm, which is shorter than a canine skull.

Habitat and Range

Prairie dogs inhabit the grasslands and plains of North America, primarily west of the Mississippi River in the United States and in northern Mexican states such as Sonora, Chihuahua, and Coahuila. In Canada, their presence is limited to the black-tailed prairie dog population in and around the west block of Grasslands National Park in Saskatchewan, which lies at the northern extent of the Great Plains. They prefer dry, flat, sparsely vegetated grasslands with fine or medium-textured soils, which are ideal for digging their complex burrow systems, and they live mainly at altitudes ranging from 600 to 3,000 metres above sea level. These habitats can experience extreme temperatures, from as warm as 38°C in summer to as cold as -37°C in winter, and are prone to environmental threats like hailstorms, blizzards, floods, drought, and prairie fires, making their burrows essential for protection.

Prairie dog burrows provide important protection from environmental threats like hailstorms, blizzards, floods, drought, and prairie fires. Burrows help prairie dogs control their body temperature as they are 5 to 10 degrees Celsius during the winter and 15 to 25 degrees Celsius in the summer. Prairie dog tunnel systems channel rainwater into the water table, which prevents runoff and erosion. They can also change the composition of the soil in a region by reversing soil compaction that can result from cattle grazing. Their mound-building encourages grass development and renewal of topsoil, with rich mineral and nutrient renewal in the soil.

Burrow Architecture and Colonies

Prairie dog burrows are 5 to 10 metres long and 2 to 3 metres below the ground. The entrance holes are generally 10 to 30 centimetres in diameter. Prairie dog burrows can have up to six entrances. They have nursery chambers for their young, chambers for night, and chambers for the winter. They also contain air chambers that may function to protect the burrow from flooding and a listening post for predators. Some mounds, known as dome craters, can be as high as 20 to 30 centimetres. Other mounds, known as rim craters, can be as high as 1 metre. Dome craters and rim craters serve as observation posts used by the animals to watch for predators. They also protect the burrows from flooding. The holes also possibly provide ventilation as the air enters through the dome crater and leaves through the rim crater.

Prairie dogs live in large colonies or 'towns', and collections of prairie dog families can span hundreds of acres. A prairie dog town may contain 15 to 26 family groups. Subgroups within a town, called 'wards', are separated by a physical barrier. The typical prairie dog territory takes up 0.05 to 1.01 hectares. Territories have well-established borders that coincide with physical barriers such as rocks and trees. The resident male of a territory defends it, and antagonistic behavior occurs between two males of different families to defend their territories. These interactions may happen 20 times per day and last five minutes. When two prairie dogs encounter each other at the edges of their territories, they stare, make bluff charges, flare their tails, chatter their teeth, and sniff each other's perianal scent glands.

Social Structure and Communication

Prairie dogs have some of the most complex systems of communication and social structures in the animal kingdom. They live in large colonies or 'towns', and collections of prairie dog families can span hundreds of acres. The prairie dog family groups are the most basic units of its society. Family groups of black-tailed and Mexican prairie dogs are called 'coteries', while 'clans' describes family groups of white-tailed, Gunnison's, and Utah prairie dogs. Although these two family groups are similar, coteries tend to be more closely knit than clans. Most prairie dog family groups are made up of one adult breeding male, two or three adult females, and one or two male offspring and one or two female offspring. Females remain in their natal groups for life, thus are the source of stability in the groups. Males leave their natal groups when they mature to find another family group to defend and breed in. Members of a family group interact through oral contact or 'kissing' and grooming one another. They do not perform these behaviors with prairie dogs from other family groups.

Con Slobodchikoff and others assert that prairie dogs use a sophisticated system of vocal communication to describe specific predators. According to him, prairie dog calls contain specific information as to what the predator is, how big it is, what color it is and how fast it is approaching. The prairie dog's alarm calls vary with different predators. For example, there are three distinct mid-pitched sounds for birds including red-tailed hawks, golden eagles and bald eagles, and four high-pitched quick sounds for mammals like coyotes, dogs, humans etc. Alarm response behavior varies according to the type of predator announced. If the alarm indicates a hawk diving toward the colony, all the prairie dogs in its flight path dive into their holes. If the alarm is for a human, all members of the colony immediately rush inside the burrows. For coyotes, the prairie dogs move to the entrance of a burrow and stand outside the entrance, observing the coyote. Perhaps the most striking of prairie dog communications is the territorial call or 'jump-yip' display of the black-tailed prairie dog. A black-tailed prairie dog stretches the length of its body vertically and throws its forefeet into the air while making a call. Studies of black-tailed prairie dogs suggest that alarm-calling is a form of kin selection. According to Slobodchikoff, these calls imply that prairie dogs have highly developed cognitive abilities.

Diet and Ecological Role

Prairie dogs are chiefly herbivorous, with grasses and leafy vegetation comprising about 98 percent of their diet, and they feed primarily on grasses like western bluegrass, blue grama, and buffalo grass, as well as small seeds. They also consume broadleaf forbs in the fall, and will eat roots, seeds, fruit, buds, and various grasses, with Gunnison's prairie dogs eating plants like rabbit brush, tumbleweeds, dandelions, saltbush, and cacti in addition to grasses, and they occasionally eat insects such as grasshoppers, cutworms, bugs, and beetles. Their grazing and clipping of vegetation around burrow entrances, keeping it shorter than about 15 centimetres, creates a unique mosaic landscape on the prairie and allows them to better see predators. This activity encourages grass development and renewal of topsoil, enriching the soil with minerals and nutrients, which is crucial for soil quality and agriculture, and lactating and pregnant females may supplement their diets with snow for extra water in the winter.

Prairie dogs are considered a keystone species, with their mounds often being used by other species. They are extremely important in the food chain, being important to diets of many animals such as the black-footed ferret, swift fox, golden eagle, bald eagle, red tailed hawk, American badger, and coyote. Other species, such as the golden-mantled ground squirrel, mountain plover, and the burrowing owl, also rely on prairie dog burrows for nesting areas. Grazing species, such as plains bison, pronghorn, and mule deer, have shown a proclivity for grazing on the same land used by prairie dogs. Their regeneration of topsoil is important for maintaining healthy humus.

Reproduction and Life Cycle

Prairie dog copulation occurs in the burrows, which reduces the risk of interruption by a competing male. They are also at less risk of predation. Behaviors that signal that a female is in estrus include underground consorting, self-licking of genitals, dust-bathing, and late entrances into the burrow at night. The licking of genitals may protect against sexually transmitted diseases and genital infections, while dust-bathing may protect against fleas and other parasites. For black-tailed prairie dogs, the resident male of the family group fathers all the offspring. Multiple paternity in litters seems to be more common in Utah and Gunnison's prairie dogs. Females may try to increase their reproduction success by mating with males outside their family groups. When copulation is over, the male is no longer interested in the female sexually, but will prevent other males from mating with her by inserting copulatory plugs.

Mother prairie dogs do most of the care for the young. In addition to nursing the young, the mother also defends the nursery chamber and collects grass for the nest. Males play their part by defending the territories and maintaining the burrows. The young spend their first six weeks below the ground being nursed. They are then weaned and begin to surface from the burrow. By five months, they are fully grown. Infanticide is known to occur in prairie dogs. Males that take over a family group will kill the offspring of the previous male. This causes the mother to go into estrus sooner. However, most infanticide is done by close relatives. Lactating females will kill the offspring of a related female both to decrease competition for the female's offspring and for increased foraging area due to a decrease in territorial defense by the victimized mother.

Conservation Status and Threats

The prairie dog habitat has been affected by direct removal by farmers, and 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 and soil quality often outweighs the benefits of removal. Other threats include disease. The prairie dog is protected in many areas to maintain local populations and ensure natural ecosystems. They are a keystone species important for maintaining natural ecosystems.

They are an important prey species, being the primary diet in prairie species such as the black-footed ferret. Conservation strategies are needed to support the recovery of associated species like the black-footed ferret that depend on them.

Prairie Dogs in Captivity and as Pets

Prairie dogs are highly social animals. They require considerable care and attention as pets. They need a very specific diet of grasses, hay, and other vegetation. Their breeding in captivity can be difficult, though they breed successfully in zoo settings. They are active animals with specific care requirements.

Prospective owners must be aware of local ordinances, as many jurisdictions have restrictions on keeping prairie dogs as pets. It is advised to check for applicable restrictions before adding a new pet to the family. The market for prairie dog pups is seasonal. Breeders often require the purchase of a starter kit to ensure proper health and nutrition for the animal. Transport costs are also an additional consideration for buyers.
