From Billions to None: The Passenger Pigeon's Flight to Extinction

Werner Herzog's documentary film about the "Grizzly Man" Timothy Treadwell and what the thirteen summers in a National Park in Alaska were like in one man's attempt to protect the grizzly bears. The film is full of unique images and a look into the spirit of a man who sacrificed himself for nature.

This is the story of the incredible struggle for survival of the dragons of the Galapagos. On the island of Fernandina, each year Land Iguanas migrate up the steep slopes of the 5000ft active volcano to lay their eggs in the warm soil. If the rim of the crater is fully occupied they have to climb 1 km down the steep crater walls to the floor below. Many are killed finding a path down as the walls are steep & dangerously unstable causing many landslides.

Flight is the ultimate superpower, an extraordinary ability that humans can only dream of. Yet an astonishing number of animals have mastered the skies. Now, new technology allows us to join them in their previously hidden world, ‘flying’ alongside these gravity-defying animals and experiencing their unique point of view. With exceptional skills and breath-taking design, creatures ranging from frogs to fish, from spiders to squirrels, spend their lives mid-air. Life in the Air captures this extraordinary animal behaviour and reveals – in incredible detail – the amazing science of flight.

Join barefoot scientist Jesús Rivas in the murky marshes of Venezuela on his quest to understand these huge, fearsome reptiles. Up to 30 feet long, weighing many times more than the scientists studying them, anacondas are difficult subjects at best, but the National Geographic team captures brilliant footage of them swimming, resting, mating, and hunting prey.

Do they really launch themselves onto the shore to grab a hapless snack? See for yourself, and gain a vivid appreciation for their appetites and skills. While your jaw drops at their fearsome agility, you’ll also be learning about their migratory and other behaviours from scientists who observe them daily and strive to increase our understanding of their needs for survival. In this National Geographic ‘Wildlife Special’ you’ll journey around the globe to see their extraordinary hunting techniques in action.

Any unlucky carcass is dispatched in a matter of minutes by a feeding frenzy that attracts jackals and hyenas along with vultures. Scavenging insects swarm over the remaining bones and horns. While this film focuses primarily on the griffin vulture (“nature’s undertaker”), it considers the role of all scavengers in this harsh ecosystem. Generally despised as harbingers of death, they actually help maintain the health of the savannah by disposing of waste and returning nutrients to the soil.

Eerie, forbidding, and darkly beautiful - Okefenokee is ruled by a relative of the dinosaur: the fearsome alligator. Day and night the alligator glides silently through its steamy realm, stony eyes just above the waterline, mouth held in a seemingly perpetual smile.

The eight lionesses soon give birth to their new leaders’ cubs and there are young everywhere, feeding, playing and training for survival. But danger lurks behind virtually every bush, whether from ever-present hyenas or from a clever mongoose. One lonely cub, born late and orphaned early, endures hardships so heart-rending the filmmakers were tempted to intervene. But they decided to let nature run its unpredictable course.

The historical saga of American superheroes. Born in the period between the Great Depression and the World War II to combat the hobgoblins of the modern world, these mutant human beings with superhuman powers colonized the funny papers, radio dramas, television and films, to become a truly national industry in the United States: they gave expression to the fears and obsessions of the twentieth century and bolstered American ideals.

Chris Packham presents, mentioning others that didn't quite make the list, his favorite top ten animal - and plant species from the half million discovered in the first decade of the 21st century. The animals include the most endangered African monkey, a lemur (Madagascar simian), a mouse-size and -resembling relative of the elephant, a Caribean island-adapted sloth, a shark which 'walks coral reefs on an arm', the largest mega-stick, a deep sea jellyfish without tentacles and a jungle gecko mutation happening in Malaysian state Perlis in order to flee serpent predation into caves. Plant species include a giant Venus-flytrap on Palawan (Philipines) and the largest ever orchid from Peru.
