Scientists Attached Cameras to Penguins—Here's What They Saw.
Scientists have historically had a hard time studying how gentoo penguins communicate with each other in the icy waters they hunt in off Antarctica.
To eavesdrop on this communication, scientists from the Korean Polar Research Institute (KOPRI) strapped the penguins with small video cameras that had built-in microphones. Their results, published in the journal Nature, are providing insights on how these iconic birds live.
They found that gentoo penguins seem to call to each other to form groups, but it's unclear what the groups' exact functions are. (Elephant seals can recognize their rival's call—hear them here.)
Over the course of two Antarctic summers, 26 individual penguins were strapped with cameras, eventually recording 598 penguin call events. Footage showed that after
