How Penguins' Body Temperature Help Them Stay Warm

Description:When scientists took infrared thermal images of emperor penguins, they found that the surface of their feathers is actually colder than the frigid air surrounding them. Feathers do not cover the penguin’s eyes, feet, and beak, so those parts of their body measured at higher temperatures. Apparently the penguins use radiative cooling to draw heat from the air around them. (1:01)
