“…Alternatively, behaving animals can be tracked by means of remote sensing devices (Kühl and Burghardt, 2013;Theriault et al, 2014;Henninger et al, 2018Henninger et al, , 2020Hughey et al, 2018;Torney et al, 2018;Raab et al, 2019;Aspillaga et al, 2021). In this approach, recorded signals can originate from small micro-transmitters that get affixed to animals (e.g., acoustic telemetry system for fish: Aspillaga et al, 2021) or from the animals themselves (photography, video recordings: Sherley et al, 2010;Lahiri et al, 2011;Theriault et al, 2014;Nourizonoz et al, 2020;ultrasound vocalizations: Surlykke and Kalko, 2008;Seibert et al, 2013;Hügel et al, 2017;electric signals: Henninger et al, 2018;Raab et al, 2019;Fortune et al, 2020). These methods benefit from minimal interference with the animals themselves.…”
