The Black-tailed Prairie Dog (Cynomys ludovicianus) has the largest distribution of any species of prairie dog and the only species in the United States with a black-tipped tail.
Description
Cynomys ludovicianus have long, black-tipped tails, which readily distinguish them from all other species in the United States. From Hoogland (1996): "Except for rare albinos (Costello, 1970; Tate, 1947), black-tailed prairie dogs are brown or reddish-brown above and whitish below."
