Find out how foxes are helping create lush gardens on the barren Arctic tundra.

Learn how filmmakers used ingenious motion sensors and remote control camera rigs to get up close and personal with the foxes of Fox Tales.

In this short video, follow the development of Red fox kits--from small and blind den-dwellers to full-size stealth predators.

In Mozambique, a young dolphin that’s left his pod encounters a rare humpback dolphin. And then something extraordinary happens – they seem to be making friends. This is the first time such a peculiar partnership has ever been filmed

In South Carolina, a pod of bottlenose dolphins has taken teamwork to a whole new level. As a group, they corral entire shoals of fish onto the shore and then devour as many as they can. Stranding is a serious hazard for dolphins, but this pod has mastered the technique.

Spy Tuna, an underwater animatronic camera, follows a 'super pod' of spinner dolphins. Spinners are known for their twisting aerial jumps, which no other dolphin species can accomplish.

In this two-part series, join John Downer Productions, producers of "EARTHflight" and "PENGUINS: Spy in the Huddle", for a front row seat into an in-depth look into the lives of dolphins. The series incorporates unique footage from 13 ingenious “spy” cameras including animatronic squid, a robotic turtle and even a dolphin “double agent”.

A lone female lynx moves silently through Austria's Kalkalpen National Park. Solitary by nature, this young female now seeks to establish her own territory. This will be the toughest time of her life, hunting in unfamiliar terrain while avoiding other lynxes.

Austria’s Kalkalpen National Park is the largest track of wilderness in the Alps, but it wasn’t always that way. The park was once the site of major logging and mining operations, but those activities ceased more than two decades ago. Three years in the making, Forest of the Lynx chronicles life in this remote wilderness and the complex partnerships among plants, insects, animals and trees.

The giant ichneumon wasp, megarhyssa rixator, has an unusual method for laying eggs. Using her overly-long ovipositor to drill deep into a tree trunk, she deposits a single egg on to the surface of an immobilized wood wasp larva. Her egg turns into a larva, that will eat the paralyzed host...bit by bit.

Spy Nautilus, an animatronic spy camera, meets a pod of bottlenose dolphins. Among their numbers is a baby dolphin, only 5 days old.

Go behind the scenes with armadillo biologist Arnaud Desbiez and the filmmakers who captured the stunning imagery featured in NATURE's Hotel Armadillo.

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.

The Giant Armadillo Project employs two vets who have developed specialist knowledge of this rare creature. They have captured female of the species and take the chance to check her general health and collect samples of her hair and blood and other tissues. So little is still known about these remarkable creatures, every piece of data is precious.

Viva Puerto Rico follows the work of three conservationists and the ways in which each is trying to restore populations of the island’s most endangered species: the Puerto Rican Amazon parrot, Leatherback turtle, and manatee.

Antillean manatees cruise the coastlines of Puerto Rico, spending most of their time feeding on the sea grass. But while they graze, they are vulnerable to being struck by speeding jet-skis and boats. At the Manatee Conservation Center, just outside the capital city of San Juan, several injured individuals and orphans are on their way to release in the wild.

Leatherback turtle hatchlings in Puerto Rico emerge at sunrise and make a mad dash to the ocean to evade capture by sea birds. The hatchlings are at the center of a legal case to protect a crucial nesting site from potential development at Dorado Beach.

The pika, a close relative of the rabbit, lives in some of the harshest environments on earth, including the Himalayas and Ural Mountains of Russia. In order to survive the long cold winter, it builds an edible nest of plant material, which serves as it's food store, as well as a cozy home.

Giant sequoias are the largest trees on Earth. They can grow for more than 3,000 years. But without fire, they cannot reproduce.

Sierra newts spend most of their lives on land, in the moist parts of the forest, but once a year they return to their place of birth to seek out a mate. The minute she enters the water, males are upon her in an instant and the competition is fierce.
