Prairie dog itself more noticeable to the predator. Predators, though, seem to have difficulty determining which prairie dog is making the call due to its "ventriloquistic" nature. Perhaps the most striking of prairie dog communications is the territorial call or "jump-yip" display of the black-tailed prairie dog. A black-tailed prairie dog will stretch the length of its body vertically and throw its forefeet into the air while making a call. A jump-yip from one prairie dog causes others nearby to do the same. Ecologists consider this rodent to be a keystone species. They are an important prey species, being the primary diet
Black-tailed prairie dog activities keep plant development in a suppressed vegetative state with higher nutritional qualities, herbivores, including red deer ("Cervus elaphus"), American bison, pronghorn ("Antilocapra americana"), and domestic cattle often prefer foraging in black-tailed prairie dog colonies. Animals that depend on herbaceous cover in sagebrush habitat, such as mule deer ("Odocoileus hemionus") and sage grouse ("Centrocercus" spp.), may be deterred by the decreased vegetative cover on black-tailed prairie dog colonies. For a list of vertebrate species associated with black-tailed prairie dog colonies, see. Biodiversity in shortgrass prairies may be at risk due to the reductions in distribution and occurrence of black-tailed prairie
