The Tigers' Fortress

Camels Down Under

This film follows a year on the exquisite west coast of Scotland, in the intimate company of a family of otters. Guided by their mother, the otter cubs survive the wildest storms of the Scottish winter, striving to overcome many challenges on their way to independence. The west coast is warmed by the Gulf Stream which is why dolphins and sharks, whales and puffins all come here to share it with the otters. Two years in the making, this film is packed with surprises and excitement and set in the most breathtaking scenery to be found anywhere in Britain.

Otters in the Stream of Life

Introduced to Australia in the 1840s by European settlers, camels were the only reliable form of transport in the country's harsh interior.

This film tells the life story of a young camel growing up in the harsh world of the outback

Seychelles: Jewels of a Lost Continent

David Attenborough travels to the remote highlands of New Guinea and the rainforests of Australia to explore the little-known world of the bower bird, a fascinating creature which flaunts its charms, steals for its own purposes and indulges in spiteful acts - all in the pursuit of the opposite sex

Bower Birds: The Art of Seduction

A colourful feature on Sri Lanka's elephant population, focusing on one of the last wild bulls. On this Buddhist island, elephants may be sacred, but they kill over people a year, and many are shot, survivors winding up in an elephant orphanage. Fifty years ago, there were ten thousand elephants and three million people on Sri Lanka; now there are two thousand elephants and 20 million people.

The Last Tusker

Wildlife programme in which state-of-the-art camera techniques reveal the sophisticated underwater world of the seal - an animal capable of surviving in every ocean corner of the world.

Seals: Invaders of the Sea

Austrian scientist Gerald Kastberger studies the aggressive giant honeybees of Assam, in particular their unexplained annual migration from the Himalayan foothills to specific trees scattered across the plains a hundred miles to the south - a distance which takes the bees three weeks to cover. Feared locally as much as the tiger, the bees attack en masse, and a hundred or more stings can kill.

Killer Bees and Magic Trees

Featuring action-packed footage of fearsome hippo bulls as they defend their territories

Hippo Beach

This is a journey along the River Thames, England's most famous river, from its source to the sea. The Thames may seem tame today but it is still wild at heart and just waiting to reclaim its lost wildness, despite our best efforts to control it. The recent flooding throughout the British Isles illustrates just how close we live to the limits of nature. London is actually sinking faster than Venice and despite huge technological innovations, such as the Thames Barrier, we are losing the battle. This winter's flooding will make everyone rethink how we live alongside the Timeless Thames.

Timeless Thames

Documentary on the coyote, cousin to the wolf and one of America's most charismatic animals. The film explores how this elusive and intelligent creature with a spine-chilling call remains an icon of the Wild West - revered by native Americans, yet hated by white ranchers - and tells its remarkable story of survival, from its stronghold in Yellowstone Park right into the heart of modern cities.

Coyote: the Ultimate Survivor?

Andrew Sachs narrates a documentary focusing on the large predators which live alongside humans in the beautiful forests and mountains of Transylvania, where shepherds always have to be on their guard for hungry wolves and bears seeking an easy meal of lamb.

Transylvania: Living with Predators

Danube Delta: Europe Untamed

A study of the buffaloes of Lake Manyara National Park, Tanzania, where they are prey to lions but will also attack
