Mammals may become familiarized with one another by body odors, without having direct contact. For instance, Columbian ground squirrels, S. columbianus, show more-cohesive and less-agonistic behaviors toward unfamiliar non-colony members if they had experienced the odor of these individuals in traps that had been used in both colonies (Hare, 1994).
