Theres a catch to studying penguins in the wild: If researchers get too close, penguins get so stressed out that they may be less likely to successfully breed or hatch an egg. So an enterprising group of scientists designed a fleet of robots-in some cases, disguised as baby penguins-to help gather data instead. When the researchers tested a small rover with a group of king penguins, the animals acted just as if a bird had passed by. Their heart rate didnt go up as it would if a human appeared, and they were less likely to try to move their eggs to another spot.
