Mini-Rover Stresses Penguins But Not As Much As Humans | Video

To keep wild King Penguins from stressing out, researchers piloted a rover to collect data from Passive Integrated Transponders tags (PIT-tags). When the rover moved, the penguins’ heart rate rose and their behaviors changed, but when it stopped moving, they went about the day normally. The stress levels were still lower than when human approached them.
