“…These included simulated threats from hunters to gauge if antipredator behaviors towards humans could provide information on hunting pressure (Bshary, ; Croes et al, ; Papworth, Milner‐Gulland, & Slocombe, ) and all three found evidence in support. Four studies used artificial foraging patches in the form of GUD experiments to investigate how human presence or human activities could affect primate risk perception (Nowak et al, ; Nowak, Hill, et al, ; Nowak, Richards, et al, ; Nowak, Wimberger, Richards, Hill, & le Roux, ). Nowak, Hill, et al () and Nowak et al () found evidence that Samango monkey ( Cercopithecus albogularis ) foraging behavior was sensitive to anthropogenic risk.…”

Predation risk affects prey species' behavior, even in the absence of a direct threat, but human‐induced environmental change may disturb ecologically significant predator–prey interactions. Here, we propose various ways in which knowledge of antipredator tactics, behavioral risk effects, and primate–predator interactions could assist in identifying human‐caused disruption to natural systems. Using behavior to evaluate primate responses to the ongoing environmental change should be a potentially effective way to make species conservation more predictive by identifying issues before a more dramatic population declines. A key challenge here is that studies of predation on primates often use data collected via direct observations of habituated animals and human presence can deter carnivores and influence subjects' perception of risk. Hence, we also review various indirect data collection methods to evaluate their effectiveness in identifying where environmental change threatens wild species, while also minimizing observer bias.

“…Animals are predicted to cease foraging earlier and leave more food behind in risky habitats than in safer areas. The results of these experiments can provide indirect evidence that anthropogenic change alters risk perception (Nowak, Hill, Wimberger, & le Roux, ; Nowak, Richards, le Roux, & Hill, ).…”

“…Nowak et al (2016) found that cagetrapping and subsequent re-exposure to cage-trap stimulus had no effect on vigilance rates in samango monkeys (Cercopithecus albogularis schwarzi). However, factors such as habitat modification or anthropogenic noise pollution have not received investigation.…”

“…Altough technology isn't fully available to allow observers to capture the looking behaviors exhibited by wild primate groups in the absence of observers (but see Nowak et al, 2016), we should not overlook the fact that the presence of observers could also be a key determinant of "looking". Just as the influence of an animal's height from the ground or number of neighbors on "looking" patterns could be subject to variation across different individuals, so too can the degree to which individuals tolerate the presence of observers.…”

What have we been looking at? A call for consistency in studies of primate vigilance

Vigilance functions to detect threats. In primates, these threats emerge from both predators and conspecifics, but a host of other social, demographic, and ecological factors have been shown to influence primate vigilance patterns. The primate vigilance literature is thus characterized by considerable variation in findings, with inconsistent or contradictory results reported not only across different species but also within species and populations across studies. Some of this variation could emerge from fundamental differences in the methods employed, making comparisons across species and groups challenging. Furthermore, identifying consistent behavioral markers for the state of vigilance appears to have proved challenging in primates, leading to a range of definitions being developed. Deviation at this level leads directly into concomitant variation at the level of sampling methodologies. As a result, the primate vigilance literature currently presents a diverse series of approaches to exploring subtly different behaviors and phenomena. This review calls for a greater consistency in studying vigilance, with the aim of encouraging future research to follow similar principles leading to more comparable results. Identifying whether an animal is in a vigilant state is challenging for most field researchers; identifying and recording a more general behavior of "looking" should though be more achievable. Experimental approaches could then be employed to understand the compatibility "looking" has with predator detection (and other threats) in individual study systems. The outcome of this approach will allow researchers to understand the key determinants of looking in their study groups and explore threat detection probabilities given an individual or group's relative level of looking.
