Rumble in the Jungle

Some animals, like elephants and whales, can speak at volumes too low for a human to hear while others, like howler monkeys, can shriek as loud as a jet taking off. Whether at infrasonic or ear-piercing levels, animals talk…a lot, whether to bond with family and friends, ward of interlopers and enemies, or simply keep their herd together. Follow scientists as they use cutting-edge tools and methods to piece together how and what animals are saying to each other and harnessing that knowledge to hopefully help restore wildlife populations.
