"Black Tailed Prairie Dog"

Black-tailed prairie dogs are often confused with other animals that are colloquially referred to as 'prairie dogs' or 'gophers'. Chief among these in Canada is the Richardson's ground squirrel. Black-tailed prarie dogs are actually much larger than ground squirrels weighing 705 - 1675 g and measuring up to 40 cm long. Males tend to be larger than females, and their weight fluctuates through the seasons. A prairie dog's weight is highest before winter, but interestingly they do not hibernate. As their name suggests, black-tailed prairie dogs differs from other prairie dogs in that it has a black tip on its tail.
