Spying on penguins is as simple as taping a camera to their backs

By capturing penguins and strapping them with video cameras, scientists created their own “penguin cam” to learn more about how birds communicate in the open ocean.
Gentoo penguins live in the islands around Antarctica and spend a lot of time in the water foraging for food, which makes them hard to access. So, scientists randomly captured 26 penguins and used waterproof tape to stick cameras on their heads and backs. Then the birds were sent back out to sea for two breeding seasons.
