Illustration of structural behaviors (bottom line and pictures), internal states (top line) and vigilance behavior (red rectangles). Large herbivores switch between different structural behaviors to satisfy prevailing needs (e.g., nutritional and safety needs) when being in state active. Here, a display of the structural behavior ‘standing with head up’ is referred to as vigilance behavior and can be utilized as index for perceived predation risk. ‘Standing with head up’ is also displayed during resting states (e.g., when animals stand in the sun for longer periods of time). Here, it can not be used as indicator of vigilance, because the animal is not forced to trade different structural behaviors to fulfill prevailing needs
