Mortality of young was highest due to heavy predation during the winter and early spring following birth. Mortality increases with dispersal from a colony or coterie. Sylvatic plague, caused by the bacterium "Yersinia pestis", can quickly eliminate entire black-tailed prairie dog colonies. Once infected, death occurs within a few days.
