Scatter-hoarding birds show superior performance in many spatial memory tasks and appear to relocate sites using different cues than nonscatter hoarders. However, there have not been similar studies of cue use and memory for locations by mammals that differ in their reliance on scatter hoards for survival. Here we report differences in spatial memory in two species of kangaroo rats that are predicted by foraging ecology. Merriam’s kangaroo rat, Dipodomys merriami, a scatter hoarder that hoards… CONTINUE READING
