“…The data from this study illustrate that each prey species responds to the unique risk predators afford, and there is a surprising lack of response by prey downwind of predators. Furthermore, vision appears to be the primary factor in driving the spatial responses of prey species to the presence of predators, compared to odor and noise, and the importance of vision accords with studies on other sensory systems (Blumstein et al, 2000;Mpemba et al, 2022) and reflects its role in the evolution of predator avoidance by ungulates in altering activity patterns (Wu et al, 2018). These results cast doubt on the current perception of the primacy of odour in ungulate predator detection.…”

Predators can induce behavioral changes in prey that influence vigilance, grouping patterns, and space use, and these can ultimately affect prey demography and trophic interactions. Consequently, prey must respond to the risk of predation, but little is known about the features that drive the spatial responses of prey species to predators. We tested what factors affected the proximity of prey to the lions reintroduced to Addo Elephant National Park, South Africa. We also tested whether prey species that are preferentially killed by lions revealed greater responsiveness than those that are not, and whether prey respond to predator behavioral states and hunger. From 1588 observations of potential prey locations in relation to lions under varying wind directions, lion behaviors, and hunger states throughout the day and night, we found no evidence of wind‐driven odor responses affecting prey proximity to lions. Prey species that were not preferentially preyed upon by lions occurred closer to lions than those species that lions prefer to hunt. Prey were closer to lions performing noisy behaviors compared to those performing quiet behaviors. Prey were more likely to be closer to covertly behaving lions and further from stationary lions. Our results, compared to the published literature and accepted dogma of the primacy of odor in predator detection, suggest large vertebrate prey responses to predators in intact, multi‐species assemblages are context dependent.
