The highest mountain range in the world, the Himalayan range is far reaching, spanning thousands of miles, and holds within it an exceptionally diverse ecology. Coniferous and subtropical forests, wetlands, and montane grasslands are as much a part of this world as the inhospitable, frozen mountaintops that tower above. The word Himalaya is Sanskrit for abode of snow, fitting for a stretch of land that houses the world’s largest non polar ice masses. Extensive glacial networks feed Asia's major rivers including the Ganges, Indus, and Brahmaputra. More than a billion people rely on these glacier-fed water sources for drinking water and agriculture. The Himalayas are not only a remarkable expanse of natural beauty. They're also crucial for our survival.

This installment of the series produced by the acclaimed Nature team showcases the grandeur of the Emerald Isle. Going beyond the usual travelogue, the film takes viewers to places they've never been before so they can truly appreciate the natural treasures of the country: the lush plant life; the animal families that call the country home, including peregrine falcons and dolphins; and the magnificent countryside, from the mountains to the bogs.

The Australian pelican is built for long distance travel. One of the largest pelicans in the pelican family, with a light skeleton and a wingspan of over eight feet, it can be airborne all day and deep into the night, riding far and high on rising thermals. When rare weather systems bring heavy rains, huge numbers of Australian pelicans abandon the sea and coastal waters and embark on a mass pilgrimage to a place a thousand miles inland. It’s the last place you would look for one of their kind, the Australian Outback, one of the driest, hottest places on the planet.

From PBS and NATURE - From the wilds of Costa Rica to the suburbs of our own country, parrot owners, rescuers, breeders, and biologists involved in conservation programs share their stories and the stories of their parrots in this bittersweet and unforgettable film about the difficulties and consequences of keeping and caring for parrots as pets.

Each year, far from human eyes, a remote expanse of Botswana's Makgadikgadi salt pans hosts one of Africa's last great spectacles when thousands of striped nomads wander the breathtakingly beautiful but barren landscape. It is only by the grace of isolated summer rains that the zebras can survive here at all. Family groups gather together to follow the rains, driven by a constant search for better grazing on islands of grass that dot the pans. Meerkat families watch the zebras come and go, and families of lions wait for them along their grueling trek, hoping for a chance to bring one down. Their journey is one that is sometimes limited by the fragility of new life, but always made possible by the strong family ties that help animals survive in one of Africa's most surreal landscapes. It's a tale of loyalty and sacrifice, of home and exile, of death and new life, in southern Africa's largest zebra population.

As the ice shrinks in the Arctic, polar bears are struggling to survive in a fast melting world. Although classified a marine mammal, the polar bear is not adapted to hunting in the water. And it is certainly no match for the world's greatest aquatic hunter -- the killer whale. In the last few years, scientists have noted an ever-growing number of killer whales in Arctic waters in the summer months. More and more have been attracted to these hunting grounds by the growing expanse of open water. They attack the same prey as the polar bears: seals, narwhal, belugas and bowhead whales.

The Okavango River empties into desert; wildlife such as fish eagles, Nile crocodiles, lions and sitatunga antelope.

Animals dance, sing, flirt, and compete with everything they’ve got to find and secure a mate. For many, the all-important bonds they share as a couple are what enable the next generation to survive. But can we call these bonds love? In this delightful, provocative look at the love life of animals, we see the feminine wiles of a young gorilla, the search for Mr. Right among a thousand flamingos, the open “marriages” of blue-footed boobies, the soap opera arrangements of gibbons, and all the subtle, outrageous, romantic antics that go into finding a partner. These are love stories all right, as various and intriguing as the lovers themselves.

As little as 15 years ago, no one had captured the unforgettable image of a leopard in its ghostly nocturnal stalk. Viewers had never seen intimate portrayals of the sleek and elusive serval, or witnessed the nighttime romps of the beautiful black-eared caracal. The team of Owen Newman and Amanda Barrett filled those gaps with a series of spectacular breakthrough films in the 1990s. Among the first to apply infrared light and night vision goggles to wildlife studies, they combined technology with intrepid determination and a strong dose of luck, illuminating the cats we hardly knew, and giving us fresh insights into those we only thought we knew, such as lions and cheetahs

River of No Return Wilderness is the largest contiguous wilderness area in the lower 48 States. Endless rugged mountains, wild rivers, forests and deep canyons define this land, home to numerous species of wildlife, including wolves, who have just returned after 50 years of near absence. A young couple, Isaac and Bjornen Babcock, chose this wilderness for their year long honeymoon. But what begins as a romantic adventure becomes something much greater for the couple, and a tale of hope and celebration for every life trying to make it in the unforgiving heart of the wilderness.

White lions are among the rarest and most treasured animals in the world. Rarer still is their survival in the wild. Their white color stands out in Africa’s wild bush country, increasing their risk of being targeted and killed by rival predators and marauding adult male lions. Only three white cubs have reached adulthood in the wilds of South Africa since white lions were first documented there in 1975. Now, two white cubs, sisters, have beaten the odds, surviving all the challenges of their youth with the help of two remarkable lionesses—their mother, Matimba, and their aunt, Khanya. Without an adult male lion to protect their small pride, Matimba and Khanya must rely solely on their own knowledge, strength and courage to protect their family.

Once facing extinction, Asia's last wild lions live dangerously close to India's villages.

In the animal world, as in our own, looks aren’t everything. In fact, some of the most aesthetically challenged creatures — from warthogs and proboscis monkeys to bull elephant seals — are also the most fascinating. A stunning variety of these ghastly yet glorious forms are explored in NATURE’s The Beauty of Ugly.

Why do some animals build structures and others don't? And how do animals decide where to build? Animal homes need to be safe and secure, protection from predators and the weather. Going above ground and under, we will investigate just what goes into making a home when you re wild and cost is not a factor.
