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. Valleys carved by glacial waters lead to hillsides covered by paddy fields containing the lifeline to the East, rice. In this world of extremes, the Himalayas reveal not only snow-capped mountains and fascinating animals but also a vital lifeline for humanity.
This programme focuses on birds. The feather is key to everything that is crucial about a bird: it is both its aerofoil and its insulator. The earliest feathers were found on a fossilised Archaeopteryx skeleton in Bavaria. However, it had claws on its wings and there is only one species alive today that does so: the hoatzin, whose chicks possess them for about a week or so. Nevertheless, it serves to illustrate the probable movement of its ancestor. It may have taken to the trees to avoid predators, and over time, its bony, reptilian tail was replaced by feathers and its heavy jaw evolved into a keratin beak.
Huge changes have swept across Arabia since the discovery of oil and the Arab relationship with nature has changed too. This is summed up by the changes to camel racing, now an ultra hi-tech sport. Arabia's animals now live alongside a very modern society but Arabia's people are using technology to protect nature: dugongs are fitted with satellite transmitters; hunting falcons chase down radio-controlled planes and the world's first carbon-neutral city is being built in the very heart of oil country.
While most of the series has focused on conflict, this episode is all about co-operation. The suitably named social spiders spin one enormous, 30m web for the whole colony, a queen bee rules her hive with a strict hierarchy and some green ants show great team spirit to help build a nest together. There are no broken societies here. David Attenborough shifts the focus to bugs that prefer cooperation rather than conflict. They include burrowing cockroaches, the suitably named social spiders - which share a 30-metre web.
In a revelatory look at Svalbard, the most northerly region in the series, Steve Backshall leaves no stone unturned as he unravels the secrets that lie covered in ice for most of each year. Svalbard is cold, dark and foreboding, yet it is home to the world's largest land predator and the most northerly population of large herbivore, but Steve discovers that the real secret to this place comes from a very different world.
With the help of some surprising creatures from around the world, this series sets out to discover how animals take to the air, defying the force all airborne animals must conquer, gravity. Part 3: Crowded Skies This episode features a creature that creates sound out of thin air with the world's fastest courtship display and arguably the world's most aggressive bird. In a South American jungle, there's 'hunt and evasion' flying during the night, as bats and moths fight for the upper hand in one of the world's oldest arms races. Plus a camera films a giant flock to unlock the secrets that keep half a million birds from colliding in the same air space.
Take a nerve-wracking dive with great white sharks as they feast on millions of sardines that fall into their trap; it’s one of the most spectacular underwater phenomenons on the planet! Plus you’ll get to patrol reefs with vigilant soldierfish, dance with balletic jellyfish and more!
