Sir David Attenborough chooses his favorite recordings from the natural world --from the song of the largest lemur to the song of the humpback whale to the song of the lyrebird-- that have revolutionized our understanding of song. The science of song had 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. 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 marvellous examples of the spectacular survival strategies that species have developed.

Fathom is a visual and aural wonder of a documentary that follows researchers working to finally decode the communication of humpback whales. Dr. Ellen Garland and Dr. Michelle Fournet embark on parallel journeys on opposite sides of the world, as they seek to better understand whale culture and communication. The film uniquely reveals a deep commitment and reverence to the scientific process and the universal human need to seek answers about the world around us.
From hypothesis to groundbreaking experiences in the field, 'Fathom' showcases the passion, curiosity, collaboration, perseverance and work it takes for leading scientists to make scientific discoveries.

Our journey begins with David Attenborough at the North Pole, as the sun returns after six months of darkness. We follow a pair of courting polar bears, which reveal a surprisingly tender side. Next stop is the giant Greenland ice cap, where waterfalls plunge into the heart of the ice and a colossal iceberg carves into the sea. Humpback whales join the largest gathering of seabirds on earth to feast in rich Alaskan waters. Further south, the tree line marks the start of the Taiga forest, containing one third of all trees on earth. Here, 25 of the world's largest wolves take on formidable bison prey. At the other end of our planet, the Antarctic begins in the Southern Ocean where surfing penguins struggle to escape a hungry sea-lion and teams of orcas create giant waves to wash seals from ice floes -a filming first. Diving below the ice, we discover prehistoric giants, including terrifying sea spiders and woodlice the size of dinner plates. Above ground, crystal caverns ring the summit of Erebus, the most southerly volcano on earth. From here we retrace the routes of early explorers across the formidable Antarctic ice-cap - the largest expanse of ice on our planet. Finally, we rejoin David at the South Pole, exactly one hundred years after Amundsen then Scott were the first humans to stand there

Narrated by Ewan McGregor, Humpback Whales is an extraordinary journey into the mysterious world of one of nature's most awe-inspiring marine mammals. Set in the spectacular waters of Alaska, Hawaii and the remote islands of Tonga, this ocean adventure offers audiences an up-close look at how these whales communicate, sing, feed, play and take care of their young. Humpbacks were nearly driven to extinction 50 years ago, but today are making a slow but remarkable recovery. Join a team of researchers as they unlock the secrets of the humpback and find out why humpbacks are the most acrobatic of all whales, why they sing their haunting songs, and why these intelligent 55-foot, 50-ton animals migrate up to 10,000 miles round-trip every year.

Millions of years ago incredible forces ripped apart the Earth's crust creating our seven continents - each with its own distinct climate, its own distinct terrain and its own unique animal life. From the colourful paradise of South America to the scorching heat of Africa, ‘Seven Worlds, One Planet’ showcases the true character of each continent in turn and reveals just how it has shaped all life there. Be surprised by unexpected stories. Marvel at iconic landscapes. And be awestruck by spectacular wildlife. This series is an eye-opening journey around a world you thought you knew.
The snowy shores and icy waters of Antarctica are home to some of the most amazing and unusual wildlife in the world. However, even here, many species face extinction due to rapid climate change and overhunting.

When animals can tap into remarkable senses and supernatural skills, crossing the globe, even moving between worlds to find a mate, safety and food, they become truly unstoppable.
