Little is known about the antipredator strategies of juvenile collared peccaries (Pecari tajacu). This note reports camera trap footage of an interaction between a young collared peccary and two potential predators, a gray fox (Urocyon cinereoargenteus) and a bobcat (Lynx rufus), as well as a personal observation of two young peccaries in what appeared to be physiological thanatosis (a state of tonic immobility). Juvenile mammals are particularly vulnerable to predation, and survivorship in this age class is a critical driver of population dynamics. Documenting the antipredator behaviors used by collared peccaries contributes to our understanding of the distribution of such behaviors among ungulate taxa, which is important in understanding the evolution of responses to predation.
