Uncover the secret lives of big cats who thrive in all four corners of the globe, from the solitary snow leopard to the nimble rusty-spotted cat, seen through the latest camera technology and science.

Discover how cats have conquered the world, thriving in almost every landscape on Earth, from the wetlands of Asia to Africa's oldest desert, to the shores of California and the tropical beaches of Costa Rica.

Scientists are studying cats in greater detail than ever before. New approaches and technologies help uncover some of the cats’ most intimate secrets, including the cheetah’s remarkable gymnastic abilities and why lions are able to hunt so cooperatively.

Discover the extraordinary abilities of squirrels, from the brainy fox squirrel, to the acrobatic gray squirrel, to the problem-solving ground squirrel. Follow a guide to the squirrel’s success along with an orphan red squirrel called Billy.

Join Sir David Attenborough as he pieces together the remarkable discovery of the Ichthyosaur, a fearsome fish lizard that lived during the age of dinosaurs.

The relationship between man and his noble steed is almost as old as civilization itself, allowing our species to explore, conquer and flourish side by side with the horse. NATURE traces this revolutionizing partnership with anthropologist Niobe Thompson in this two-part series.

Discover how humans have partnered with the horse throughout the centuries, creating more than 350 breeds found all around the world.

Experience the natural world through the eyes of the Vikings. From the killer whales of the North Sea to the volcanic mounts of Iceland, see the deep history and cultural respect the Vikings had with the land and sea. Ewan McGregor narrates.

How is an egg made? Why are they the shape they are? And perhaps most importantly, why lay an egg at all? Step by step as the egg hatches, host David Attenborough reveals the wonder behind these incredible miracles of nature.

Broadcast over three consecutive days from iconic locations across North America – varied ecosystems ranging from the Rockies to the Everglades, from inner-city parks to remote wilderness preserves - this special live event celebrates spring as a time of renewed energy and awakening in the natural world.

Breeding and the greening of the landscape are tied to another major spectacle of spring: the mass movements of animals as they take advantage of spring’s bounty. Meet the scientists who track the journeys of animals such as butterflies, birds, bison and bats over vast distances, from winter refuge to spring nesting grounds.

Learn how plants and animals depend on each other to survive. See first-hand how climate change can break those connections, altering the timing of weather and plant growth, and disrupting the delicate relationships between plants and pollinators such as moths, bees and butterflies.
