Skuas are large sea birds that have a talent for poaching eggs. Go along for the ride as a skua grabs what it thinks is a penguin egg, but is really a hidden 'spy camera'.

Teenage male dolphins are notoriously ill-behaved. A 'Spy Turtle' and 'Spy Pufferfish' keep tabs on all of their bad behavior.

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 convenient partnership between real crocodiles and birds.

"Spy in the Wild" series producer Matt Gordon recounts the humorous behavior of some wild chimps as they interact with an animatronic bushbaby.

Meerkat sentries protect the group by keeping a watch out for potential predators. A female sentry spots a cobra and tries to run it off. Little does she know, the 'cobra' is actually a sophisticated fake outfitted with a hidden camera.

The water dikkop (Burhinus vermiculatus) locates its nest close to the nest of the Nile crocodile for protection from other predators. However, Nile crocs are extremely territorial and being in such close proximity leads to some feather-raising situations.

A female orangutan shows off her sawing skills in a contest with an animatronic 'spy orangutan.'

A robotic 'spy sloth' gets a close-up view of the mini-ecosystem contained in a sloth's fur. Eeeww...gross!

NATURE’s Executive Producer Fred Kaufman and Director John Downer discuss the making of SPY IN THE WILD

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.

This most innovative series employs more than 50 animatronic "spy cameras" disguised as animals to secretly record behavior in the wild. Featured robotic look-alikes will infiltrate the natural world to film surprisingly human-like behavior, such as chimps that keep pets; dolphins that bear gifts; meerkat babysitters; birds that try to impress the females; and much more.

In the most innovative series NATURE has ever presented, the five-part “Spy in the Wild” employs over 30 animatronic “spycams” disguised as animals to secretly record behavior in the wild. These spy cameras reveal animals as having emotions and behavior similar to humans – specifically, a capacity to love, grieve, deceive, cooperate, and invent.

The coldest and snowiest places on earth, such as the Arctic Circle or Antarctica, pose a challenge to human visitors. But what about the year-round animal population? How do they cope for many months with life in these frozen wonderlands where temperatures can plummet to as low as minus 50 degrees? Find out how these creature adapt to their surroundings or employ clever tactics to survive.

With acute senses the arctic fox can hear lemmings under the snow. To catch one he uses a special pouncing technique known as ‘moussing’. But moussing isn’t always easy-–especially for a beginner!

Reindeer traditionally pull sleighs and have a popular reputation for red, glowing noses. But behind this folklore there is some surprising truth – an in-genius adaptation which helps them survive the extremes.

With their aquatic skills – and powerful bite – jaguars are able to prey on the crocodile-like caiman. An extraordinary act of such predation was filmed by a tourist in Brazil’s Pantanal.

The American pronghorn is the second fastest land mammal on the planet - reaching speeds of fifty miles an hour. But it’s pace long baffled scientists. It’s speculated that an arms race between the american cheetah and the pronghorn may be the reason for the antelope’s remarkable speed.
