Black-tailed Prairie Dog
There are five species of Prairie Dog, related to Ground Squirrels. All are native to North or Central America.
Above is the Black-tailed Prairie Dog which does not have a black tail but has a black tip to its tail. It is native to the prairies of North America.
One of the most common species, its range covers from within Canada to within Mexico. It lives in gregarious "towns" of thousands of individuals.
They live in dens in interconnected burrows. This mother is stealing straw from a farmyard to line her den.
In addition to baby-rearing dens, the burrows have food storage "rooms" and defecating rooms. Other animals also use prarie dog burrows for shelter.
They are believed to vary their alarm calls to identify which predator/danger from whence and possibly to communicate other information by varying calls.
