David Attenborough presents seven of the most remarkable animal songs found in nature and explores the significance of these songs in the lives of their species. Each one - from the song of the largest lemur to the song of the humpback whale to the song of the lyrebird - was recorded in his lifetime. But will they soon be heard no more? Contrary to Charles Darwin's theory of sexual selection, a new generation of scientists have discovered that animal song is not just the preserve of males. Females sing too. But there are also fears that we do not have much longer to hear them. Because as humankind gets noisier, the rest of the planet is falling silent. Joyous, surprising and poignant, this story of pioneering research and astounding insight is a chorus of wonder and a wake-up call.
