Abstract

Some ecological characteristics of 25 white-tailed (Cynomys leucurus) and 21 black-tailed (C. ludovicianus) prairie dog colonies in Wyoming were compared. The size of colonies and density of burrow openings were similar for the two species, but the number of white-tailed prairie dog colonies per 100 km2 and the number of hectares occupied by white-tails per 100 km2 were 3.7 and 4.6 times greater, respectively, than for black-tails. Sixty-four vertebrate species (22 mammals, 33 birds, five reptiles, and four amphibians) were found on prairie dog colonies. The ecological relationships between prairie dogs and associated vertebrate predator species and the history of prairie dog control in Wyoming are discussed.
