Natural World The Amber Time Machine

The harpy eagle is the most powerful bird of prey in the world, plucking monkeys from the branches of the jungle canopy. Rare and elusive, they are seldom seen, but with the discovery of a harpy nest in the remote Orinoco rainforest of Venezuela, wildlife film-maker Fergus Beeley has a unique opportunity to follow the life of a chick from birth to adulthood.

The squirrel family is one of the most widespread on earth, so what is the secret to their success? There are squirrels that can glide through the air, outwit rattlesnakes and survive the coldest temperatures of any mammal. We uncover the extraordinary abilities of these cheeky characters, putting their problem solving to the test on a specially designed assault course. We team up with some of the world's top squirrel scientists who are making groundbreaking discoveries - from the fox squirrel who can remember the location of 9,000 nuts to the grey squirrel whose tree-top leaps are the basis of new designs in robotics.

Sri Lanka, the tropical island lying off the southern coast of India, is home to its own special elephants. A subspecies of the Asian elephant, they have their own unique characteristics. In this programme, award-winning wildlife cameraman Martyn Colbeck of Echo of the Elephants fame travels to Sri Lanka to try and get to know them.

David Attenborough narrates a documentary looking at the wildlife of the most stunning mountain range in the world, home to snow leopards, Himalayan wolves and Tibetan bears. Snow leopards stalk their prey among the highest peaks. Concealed by snowfall, the chase is watched by golden eagles circling above. On the harsh plains of the Tibetan plateau live extraordinary bears and square-faced foxes hunting small rodents to survive. In the alpine forests, dancing pheasants have even influenced rival border guards in their ritualistic displays.

The harpy eagle is the most powerful bird of prey in the world, plucking monkeys from the branches of the jungle canopy. Rare and elusive, they are seldom seen, but with the discovery of a harpy nest in the remote Orinoco rainforest of Venezuela, wildlife film-maker Fergus Beeley has a unique opportunity to follow the life of a chick from birth to adulthood. Fergus ascends high into the canopy to reveal a stunning world of colour and sound, following the trials of the harpy eagle's newly hatched chick as it grows up. Fergus becomes just another member of the dazzling community of birds and animals surrounding the harpy nest and develops an unexpectedly close bond with the chick.

A professor develops an extraordinary relationship with an octopus when he invites it to live in his home. The octopus, called Heidi, unravels puzzles, recognises individual humans and even watches TV with the family. The episode also shows remarkable behaviour from around the world - from the day octopus, which can change colour and texture in a split second, to the coconut octopus, which carries around its own coconut shell to hide in. But most fascinating of all is seeing how Professor David Scheel and his daughter Laurel bond with an animal that has nine brains, three hearts and blue blood running through its veins.

Seals, parakeets and even pelicans that eat pigeons have all made London their home. That's as well as badgers, foxes, scorpions, and pigeons that ride the tube. But even more wonderful are the people who love the exotic wildlife of our capital, from Billingsgate fish porters to Indian Chefs to ‘Crayfish Bob’, who scour London's canals for Turkish invaders. This is a warm-hearted portrait of the world's greenest capital city and the Londoners who love its secret wildlife.

Professor David Scheel takes an octopus into his home to learn about its intelligence and the extraordinary relationship he and his daughter develop with the creature. Named Heidi, the octopus is seen unravelling puzzles, recognising individual humans and even watching TV with the family. The film also looks at the remarkable behaviour of other octopuses around the world, from those that can change their colour and texture in a split second to the octopus that carries around its own coconut shell to hide in.

The remarkable story of 43-year-old Sudan, the very last male northern white rhino on the planet. Aged just three, Sudan was snatched from his mother's side in Central Africa. He became a prized exhibit in a zoo behind the Iron Curtain, while the rest of his kind was poached to extinction in the wild. Today, Sudan has become an unwitting celebrity and the focus of a desperate eleventh hour battle to save his sub-species. This astonishing modern-day fable is told through the international cast of characters who have been involved in Sudan's life, for better and for worse.
