Episode list

With high speed camerawork and breakthrough new science, we enter the fast-paced world of hummingbirds as never before. Speed is their middle name. Their lives are moving faster than the eye can see. They possess natural born super powers that enable them to fly backwards, upside-down, and float in mid-air. And for the first time, we see them mate, lay eggs, fight, and raise families in intimate detail. They are great athletes, tender mothers, brave in combat, and up for any challenge. They are Super Hummingbirds, the smallest, most brilliant birds on earth.

Vianet D'jenguet has lived half of his life in Europe, yet his heart still lies in his homeland, his Congo. As a successful wildlife cameraman, D'jenguet is returning to his roots to reveal the beauty and majesty of his country and its people. During his journey, D'jenguet explores a vibrant "African Eden" - a Congo complete with chimps, gorillas, weaver birds, Colobus monkeys, swamp antelopes, forest elephants and buffalo - and a jungle tribe who still reveres his great-grandfather. D'jenguet shines a spotlight on his beloved homeland and discovers an even deeper connection with this place than he ever imagined.

Everyone loves giraffes, but what do we really know about them? Dr. Julian Fennessy has spent the last 20 years of his life studying giraffes. Now he's starting to reveal their secrets- the most important being that they are disappearing. The giraffe population in Africa is down by 40 percent in just two decades. In collaboration with a determined Ugandan Wildlife Authority team, Fennessy wants to round up 20 of the world's rarest giraffes to get them to safety through the wild heart of Uganda, which means embarking on a special voyage across the mighty Nile River. The stakes are high in this urgent and daring mission against poachers affiliated with organized crime, but if successful, the reward will be a brighter future for an animal we have somehow overlooked.

Cats are among the most feared and revered creatures on the planet. Their power, strength, and enigmatic nature have fascinated us for centuries. They are one of the most studied mammals in the world yet only now is their real identity being understood - from their incredible hunting abilities, to their unique physiology and remarkable behaviors. With nearly 40 different species, thriving in almost any environment, the cat is one of the most successful predators since the dinosaurs. Using the latest camera technology and working with leading scientists, we are able to tell the story like never before. Join Nature in this epic two-part event as we journey across the globe tracking down the origins of these diverse creatures. Take an in-depth look at what makes the family of felines unique and the evolutionary tricks and adaptions that truly make a cat, a cat. In Part 1, discover how the first cats arose in the forests of Asia, how they spread across the continent and later came to conquer Africa. We reveal how cats evolved with an in-depth look at lions, servals, caracals, cheetahs, tigers, fishing and sand cats.

Meet the mighty jaguar, the urban mountain lion, the curious ocelot, the Canada lynx, the nimble margay, the Siamese cat and the Sphynx.

The coldest and snowiest places on earth pose a challenge to human visitors. What about the year-round animal population? How do they cope for many months in these frozen wonderlands where temperatures can plummet to as low as -50 degrees?

Spy Creatures explore the rarely seen emotions of animals, revealing if they are as strong and complex as our own. Join the "spycams" as they are accepted into a wild dog pack, witness elephant love, and are mourned by a troop of monkeys.

Spy Creatures infiltrate the world of animal intelligence, ingenuity, and creativity. Watch our spies disguised as animals observe a gray squirrel stealing Spy Nut, a sea otter cracking open a meal, and an orangutan washing with soap.

Spy Creatures and their new wild friends rely on each other to look out for predators. A Spy Meerkat babysits meerkat pups while a Spy Cobra pretends to attack the mob. Spy Crocs witness a partnership between real crocodiles and birds.

Spy Creatures infiltrate the underground world of animal mischief, crime, and retribution. Spy Monkey is caught between crossfires as real monkeys fight over beach bar alcohol. Spy Egret is also a waterhole victim when elephants throw mud everywhere.

The final episode explains how the concept of the Spy Creatures evolved at John Downer Productions from the original Bouldercam to the Penguincams that inspired the next-generation "spycams" featured in this series.

The Sierra Nevada, a mountain range running about 400 miles along the eastern side of California and stretches into Nevada, is home to three national parks: Sequoia, Kings Canyon and Yosemite. This is a land of giants, whether speaking of trees soaring to nearly 300 feet, or massive stone monoliths far taller than any skyscraper. But the force that has given rise to the earth's largest living trees and carved out the iconic natural landmarks of the Sierras is water. The role that water has played in the creation and evolution of Yosemite Valley cannot be overstated - feeding its numerous wild rivers and countless waterfalls, and making life in this stone wilderness possible. The second force, crucial to the Giant sequoias' ability to reproduce, is fire. It is the delicate balance of these two elements, water and fire, that is vital to the continued existence of the wildlife and trees that inhabit the Sierras. Despite the recent heavy rains and snowfall, scientists are finding that water is scarcer and the threat of fire is more likely as the area continues to experience rising temperatures upsetting that important balance. Geologists, ecologists, researchers and adventurers investigate how the changing climate is affecting one of America's greatest wildernesses.

Puerto Rico is a tropical island infused with unique natural wonders - from the deepest sea-trench to the longest underground cave system; from a startlingly bright bioluminescent bay to vast rain forests that sometimes really do rain frogs. A native Puerto Rican frog, called a coqui, sometimes floats down from high in the forest canopy. It's become the unofficial mascot of Puerto Rico and is one of many unusual endemic species that inhabit the island. The film is a personal portrait of Puerto Rico's natural history seen through the eyes of one its most charismatic conservationists, Tony Mignucci. A key narrative thread is the story of Mignucci's battle to save the Caribbean manatee from extinction. Each year up to 15 manatees are stranded off the coast of Puerto Rico, and Nature follows his efforts to save and release them into the wild.

You won't find this hotel on the beaches of Rio. Deep in the heart of the Brazilian wetlands, the mysterious and secretive Giant armadillo digs a new burrow every other night. Once this termite-eater moves on, it leaves behind one of the hottest plots of real estate in the tropical Pantanal for 80 species of diverse and ever-changing animal clientele. We'll get a never-before-seen look as guests walk, squawk, slither, and crawl from far and wide to get the best room available. From families of nursing anteaters to foraging coatis, the "Hotel Armadillo" showcases all the grasslands have to offer along with the scientists who "check in" these exotic guests.

Forests are far more complex than previously imagined. Travel deep into the remote forests of the Kalkalpen National Park in Austria - the largest area of wilderness in the Alps. Abandoned and unmanaged by man for close to a quarter of a century, the forest's dramatic cycle of growth and decay now rules the landscape. What appears at first to be devastation and destruction is in fact part of the fundamental process of the forest's regeneration and transformation back to its natural, primeval state - along with pygmy owls, woodpeckers, and colorful insects. One of the most salient changes in the forest, however, is the return of the lynx. After 150 years of absence, the feline's elusive presence is a testimony to nature's power of revival, making the lynx the symbol of the forest.

The most widespread and best-known dolphin, the bottlenose, is introduced. Females and males live in separate pods and are free to come and go, but there's usually a core group that may be friends for life.

The different hunting targets of the orca, the world's largest dolphin, are shown. Also the dolphins' initiation rites, strange rituals, and unusual sleeping methods are presented.
