Cynomys ludovicianus
Prairie Dog (Black-tailed)


They are found in the prairie regions of south-central Canada south through the prairies of the U.S. in Montana, Wyoming, North and South Dakota, Oklahoma, Nebraska, Colorado, New Mexico, Arizona, Oklahoma and Texas.


They live in dry, lowland mid to short-grass prairies. They like flat, open lands.

Body Traits

They can be up to 17” long and weigh up to 3.5 pounds. They are tan to light brown on back with a white belly, though it’s not unusual to see some that are reddish or even black. The tips of their tails have black hair. They have short ears and large black eyes. Males are larger than females.


They live in colonies called “towns” made up of vast underground tunnels that can have hundreds of prairie dogs. Each town has smaller groupings called neighborhoods (or coteries). When males grow up they leave their neighborhood and join another. Females stay at home in their own neighborhood. They are all very territorial and will defend their neighborhoods. They are active during the day (diurnal) all year. Black tailed prairie dogs do not hibernate.


They eat plants. In their habitat the plants that are available for them to eat are leaves, stems and roots of grasses. It in not unusual for them to eat insects like: grasshopper and beetles too.


They are eaten by badgers, coyote, foxes, bobcats, golden eagles, hawks, and rattlesnakes.
