The Peruvian jungle in the upper reaches of the Amazon is home to two different species of monkeys, the Andean titi and the brown-mantled tamarin. What's interesting is that these two species live side by side as if they were members of a single troop. When titis feed on insects, they rely on tamarins to catch them. Meanwhile, tamarins use titis to get Inga beans to eat. To protect against predators, titis keep their eyes aloft looking out for birds of prey, while tamarins keep an eye to the ground for carnivores and large snakes.
The canals that crisscross England have long supported rich natural habitats. Along the Macclesfield Canal, in central England, diving rodents called water voles hunt for prey below the water's surface. Kingfishers alight on the trees that line the banks, intently eying the flowing water, then swooping down on unsuspecting fish. In spring and summer, flowers burst forth in waves of color. This program depicts the four seasons along England's canals, where people and nature live in splendid harmony.
Monterey Bay has a dense underwater forest of giant kelp - the largest on Earth. This forest of 60-meter long kelp provides an ideal habitat for sea otters. This program follows a family of sea otters living in close harmony with this environment, revealing not only how sea otters thrive amongst the kelp but how they also help protect the kelp in turn. The mother spends all of her time and energy raising her newborn. Her young pup learns how to crack open shellfish by imitating her. She desperately tries to protect her young from a seagull attack. These are just some of the amazing moments captured in this rare and intimate animal family portrait.
Over the centuries, the emerald green Tara River in Montenegro on the Balkan Peninsula has etched a canyon 1,300 meters deep. The views throughout the Tara Canyon are spectacular. Up to 700 varieties of plants blanket its undulating hills. Herds of chamois live on the steep slopes where no human can venture. They nimbly roam the rocky cliffs, in perpetual danger of falling. Golden eagles circle imperiously overhead, waiting for the chance to strike. Living on the Edge chronicles a year in the life of the magnificent Tara Canyon featuring an up-close look at the chamois that live there.
During the dry season, the grasses in the savanna region in northwestern Tanzania wither, forcing animals to look elsewhere for food. But a green paradise exists in the middle of the region surrounded by a huge outer rim of a volcanic crater 20 kilometers in diameter. This is the Ngorongoro Crater. Inside this paradise there is a wetland area, watered by abundant springs even during the dry season. It seems a different world, where wild animal life abounds, including endangered animals such as black rhinoceroses, lions, and cheetahs. Why does this unique environment exist only here? Unlikely Eden explores the secrets of the Ngorongoro Crater, the home to such a wealth of wildlife.
