Small Australian cuttlefish males can't strong arm larger rivals, so they resort to a clever deception in order to win a mate.

Female red kangaroos sneak off with beta males to help preserve genetic diversity.

The duplicitous ways in which animals try to secure their next meal is the subject of the second episode, The Hunger Hustle.

This three-part series reveals the modus operandi of some of nature’s greatest animal con artists as they outwit predators, line up their next meal, and get the girl. The first episode, Staying Alive, offers stories about unusual survival techniques.

An African lioness that looks and acts male may be the secret to her pride's success.

Our pets may seem familiar but they exist alongside us in a secret world of wild behavior and natural abilities that we hardly recognize. This two-part series explores this parallel existence with all the techniques that have been perfected in past “spy” shows, including HD spy cameras, night vision cameras, drones, miniature on-board cameras and digital high-speed cameras.

A baby elephant, only days old, chases birds on the African savannah and learns how to solicit milk from his mother.

An intimate look into the lives of one of the world’s most intelligent and sensitive animals through the uniquely personal lens of filmmakers Dereck and Beverly Joubert.

It may seem strange that among the more than 10,000 bird species in the world today is a group that literally cannot fly or sing, and whose wings are more fluff than feather. These are the ratites: the ostrich, emu, rhea, kiwi and cassowary. How and why these birds abandoned flight has puzzled scientists since Darwin’s time, but DNA and dedicated research are helping to solve these mysteries.

Growing up in the wild is hard enough on young animals when they have parents to rely on for protection and guidance, but what happens when they lose their parents? How do they survive? Over the past few years, great strides have been made in understanding how to rescue and rehabilitate orphaned wildlife.

One of the most overlooked ecosystems on the continent consists of a massive sea of sagebrush that stretches across 11 states in the American West. This spartan yet spectacular landscape supports more than 170 species of hardscrabble birds and mammals. And among those that have adapted to survive here are birds found no place else – Greater Sage-Grouse.

In the springtime, male greater sage-grouse (Centrocercus urophasianus) gather in groups, called leks, to compete for females. Males guard a territory a few meters in size (on average) and try to attract a mate by ruffling feathers and making a distinctive noise produced by air sacks in the chest.

The pronghorn is the fastest land animal in North America. However, an increasingly fragmented landscape, divided by ranchers' fences, is creating problems for the fleet-footed creature.

In every animal’s life, there comes a time when it must stand on its own two feet, so to speak, and face the world alone. For a few, this happens just moments after birth, with no life lessons from parents to help them, no time to hone their survival skills. Others have the advantage of home schooling under the watchful eye of a mentor or family member.

The nubian ibex (Capra nubiana) is a desert-dwelling goat that gives birth to young atop tall windswept mesas. The mesa's steep cliff faces offer protection from predators. When the offspring are a few days old they must scale these cliff faces to reach food in the valleys below.

Representing the meticulous and ambitious work of an all-Chinese film company led by award-winning filmmaker, Xi Zhinong, this spectacular film is the true story of a family of Yunnan snub-nosed monkeys living in the highest forests in the world.

Two black snub-nosed monkey brothers play and wrestle among the tree tops, annoying the rest of the troop who are trying to rest. One of the brothers was abandoned by his mother; the other is treated like a prince.

A juvenile Yunnan snub-nosed monkey is abandoned by his mother while his half-brother becomes the favorite. In order to survive he must depend on the generosity of his other family members.
