David Attenborough takes a breathtaking journey through the vast and diverse continent of Africa as it has never been seen before. (Part 3: Congo) The very heart of Africa is covered in dense tropical rainforest. The animals that live here find the most ingenious ways to carve out their space in a claustrophobic landscape. Danger lurks in every shadow, but some animals thrive here, from honey-stealing chimps to birds with a lineage as old as the dinosaurs, thundering elephants and kick-boxing frogs. Here in the Congo, no matter how tough the competition, you must stand up and fight for yourself and your patch.

The Messenger explores our deep-seated connection to birds and warns that the uncertain fate of songbirds might mirror our own. Moving from the northern reaches of the Boreal Forest to the base of Mount Ararat in Turkey to the streets of New York, The Messenger brings us face-to-face with a remarkable variety of human-made perils that have devastated thrushes, warblers, orioles, tanagers, grosbeaks and many other airborne music-makers. In ancient times humans looked to the flight and songs of birds to protect the future. Today once again, birds have something to tell us.

Sir David Attenborough chooses his favourite recordings from the natural world that have revolutionised our understanding of song. 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. When Sir David was born, the science of song had already been transformed by Charles Darwin’s theory of sexual selection: singing is dangerous as it reveals the singer’s location to predators, but it also offers the male a huge reward, the chance to attract a female and pass on genes to the next generation. Hence males sing and females don't. Today, new science in the field of birdsong is transforming those long-held ideas. Scientists are discovering that, in fact, in the majority of all songbird species, females sing - and it is only now they are being properly heard. Through this revelation and others, we can understand that animal songs are marvelous examples of the spectacular survival strategies that species have developed in order to stay alive.
