Black-tailed Prairie Dog

Here at Wildwood Zoo, we have a large coterie of 15 prairie dogs! This group was introduced to the exhibit in the spring of 2021 following exhibit upgrades and renovations. We hope these prairie dogs and their offspring will flourish at the zoo for generations to come!

Prairie dogs occur only in North America. Generally, the black-tailed prairie dog occurs east of the other four species in more mesic habitat. Prairie dogs are small, stout rodents that are a member of the squirrel family. The total length of an adult black-tailed prairie dog is approximately 14-17 inches. The weight of an Prairie Dogindividual ranges from 1 to 3 pounds. Individual appearances within the species vary in mixed colors of brown, black, gray, and white. The black-tipped tail is characteristic.  Black-tailed prairie dogs are diurnal, burrowing animals that do not hibernate. The black-footed ferret, swift fox, mountain plover, ferruginous hawk, and burrowing owl are dependent upon prairie dogs, using their burrows to live in and to find food.

The historic range of the black-tailed prairie dog included portions of 11 states, Canada, and Mexico. map_prairie_dogsThe species is currently present in 11 states including Arizona, Colorado, Kansas, Montana, Nebraska, New Mexico, North Dakota, Oklahoma, South Dakota, Texas, and Wyoming.

Black-tailed prairie dogs typically inhabit short-grass prairies; they usually avoid areas of heavy brush and tall grass, possibly because visibility is considerably reduced.

Reproduction occurs once per year, with the exact timing of mating varying with latitude. In Oklahoma, breeding takes place in January; in Colorado breeding takes place in February. Between late February and March, black-tailed prairie dogs in South Dakota breed. Finally, those animals residing in the northern portions of the species range breed in late March and early April. Females of this species are typically sexually receptive only one day of the year. Females failing to conceive after this initial estrus sometimes enter estrus a second time about 13 days after their first estrus. Gestation ranges in length from 33 to 38 days. Litter sizes at birth range from 1 to 8 young. Young are hairless, being born blind, naked, and mostly helpless. BabyFur is evident by the age of 3 weeks, and eyes are open by approximately 5 weeks of age.

Life Expectancy
In the wild: 1-5 years
In human care: 9 years

Natural Diet
Black-tailed prairie dogs eat primarily leaves, stems, and roots of grasses, weeds, and forbs. Although vegetable matter comprises over 98% of the diet, animal matter may sometimes be ingested. The animals typically eaten by prairie dogs are grasshoppers, cutworms, bugs, and beetles. Wild black-tailed prairie dogs do not need to drink water in order to get the moisture they need to survive. They obtain all the moisture they need from their moist, leafy foods. Most prairie dogs forage close to their burrows when possible, moving into distant foraging areas only when forced to do so by local shortages of green shoots.
