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.

A captivating world of creepy crawlies exists all around us. And they are the biggest group of animals in the world, outnumbering humans 200 million to one. Thanks to millions of years of evolution, these invertebrates not only survive in almost every landscape known to man, but also thrive by means of fascinating, and sometimes bizarre adaptations. There's the Bombardier beetle that squirts a boiling hot liquid from its anus, the Assassin bug that turns its victims into soup, and the Parasitic wasp that lays her eggs inside her victims, until her young are ready to eat their way out. We end off with the biggest bugs on the planet: the Atlas moth with a wingspan of over 20 centimetres, the Hercules beetle that can carry 850 times its own weight, and the Giant centipede - big enough to catch flying bats from midair!

David Attenborough meets the omnivores - the opportunists. When it comes to food, this diverse range of animals, which includes grizzly bears at one end and rats on the other, are so adaptable that they can always make the most of whatever happens to be around at the time. They are nature's generalists but each is equipped with some very specialised skills.

In 1960, a young secretary from Bournemouth, with no scientific qualifications, entered a remote forest in Africa and achieved something nobody else had ever done before. Jane Goodall became accepted by a group of wild chimpanzees, making discoveries that transformed our understanding of them, and challenged the way we define ourselves as human beings by showing just how close we are as a species to our nearest living relatives. Since then, both she and the chimps of Gombe in Tanzania have become world famous - Jane as the beauty of many wildlife films, they as the beasts with something profound to tell us. As one of the programme's contributors, David Attenborough, suggests, Jane Goodall's story could be a fable if it wasn't true. In this revealing programme filmed with Jane Goodall in Africa, we discover the person behind the myth, what motivates her and the personal cost her life's work has exacted from her - and why she still thinks we have a lot to learn from the chimps she has devoted her life to understanding.
