Prairie dogs and grasshopper mice interact closely on prairie dog colonies. Left: Grasshopper mouse running into prairie dog burrow (photograph: Kim Pollard). Right: Evidence of grasshopper mouse interactions with prairie dog carcasses. The prairie dog carcass (roadkill) had been previously intact and had been placed on a prairie dog colony to estimate rates of removal by carnivores (see Boone et al. 2006). Simultaneously, grasshopper mice on the prairie dog colony were being tracked by marking with fluorescent powder. The ring of pink fluorescent powder around the gaping hole in the prairie dog reveals that a grasshopper mouse scavenged this prairie dog's entrails (photograph: John Kraft).
