Acceleration signal of the x- (black), y- (red) and z-axis (blue). Left plot shows the raw acceleration data transformed to values in g. Top right shows static body acceleration (sba, calculated with a window width of seven data points); bottom right shows mean dynamic body acceleration (mba_w2, calculated with a window width of 22 data points) of the same burst (see Table 3 for a detailed description of the predictor variables). In the first 5 s the animal is browsing with the head below shoulder height. Afterward, the head is raised above shoulder height and the animal is standing
