An Indonesian legend claims that monkeys can speak but they prefer to stay quiet. Do animals have languages that we don't understand? Is it just a question of getting the right dictionary or is language the one thing that separates humans from the rest of the animal kingdom? Birds sing, lions roar and chimpanzees chatter but do these noises mean anything? This one-hour documentary takes viewers into the wild to listen to nature's noisemakers and meet some of the scientists who spend their days trying to have conversations with animals. From parrots to killer whales we find out who is saying what to whom and explore whether there is such a thing as animal language.
