Five-second snapshots of calibrated triaxial magnetometer data for the four behaviours of interest for a typical individual (recording session #1). The horizontal axis shows time in seconds, and the vertical axis represents calibrated, normalised magnetic field intensity measured along the three axes of the sensor in each graph. The signals correspond, from left to right, to bipedal vigilance, curled-up resting, foraging, and running
