Biologging and remote-sensing of behavior

The fast-occurring technological advancement has allowed the growth of biologging and remote sensing applications in the field of animal behavior. In particular, tracking loggers allow the collection of spatial data to investigate individual space use, proximity loggers to monitor interactions, accelerometers to detect activity patterns, camera traps to detect species occurrence, locomotion, heartbeat or temperature sensors to measure the internal or external state of animals. Here we describe a wide array of methods for tracking animals, focusing on the classification of different typologies of loggers, and discussing the best practice for their application to animal behavior studies.
