“…To test this hypothesis, however, more fine-scale measurements of the behaviour of multiple predators (simultaneously) are required. Methods include: biologgers or mounted video to record changes in animal behaviour indicative of predator selection or prey detection Christie et al, 2016;Harvey et al, 2016;Hodgson & Koh, 2016;Hubel et al, 2016b,a;Marras et al, 2015b;Jackson et al, 2016;Handley et al, 2018;Torney et al, 2018;Westley et al, 2018;Wilson et al, 2018;Hughey et al, 2018;King et al, 2018;Couzin & Heins, 2022;Hansen et al, 2022;Koger et al, 2023). Differences in predator locomotion and within-group position may indeed correspond to changes in informational state (Bode et al, 2010;Shubkina et al, 2010Shubkina et al, , 2012Herbert-Read et al, 2019) and network-based diffusion analysis (Franz & Nunn, 2009;Hoppitt, 2017) or methodology borrowed from information theory and tested in laboratory animals (Ward et al, 2018;Hansen et al, 2021;Burns et al, 2022) can then assess if these state changes are transferred socially (Fig.…”
