Scientists and bee experts discuss the crucial role that honeybees, a "keystone species," play in our economy and ecosystems, as well as bees' fascinating social organization and what we can do to reverse the decline of nature's pollinators.

Following the path of the condor, whose ten-foot wingspan enables it to soar effortlessly over the peaks of the Andes mountains, this film starts at the storm beaten rocks of Cape Horn at the southern tip of South America and journeys north to the highest peak in the Americas - Aconcagua. Along the way, we see exotic animals and birds such as the penguin, hummingbird, sea otter, guanaco, ostrich-like rhea, and puma.

While the cold waters of the Pacific Coast of South America are among the richest in the world, the shore is the driest desert in the world. Yet it is not at all devoid of life. Lizards snatch morsels from the waves, and seagulls fly 40 miles into the desert to nest. The condor searches for carrion and vampire bats feed on the blood of sleeping sea lions. This is a beautiful portrait of a giant land.

The third part of the series is a spectacular visual trip down the fabled river. From the snow-clad summit of the volcano Cotopaxi and others comes the greatest river in the world as melting ice creates a torrent that drops three miles in its first short distance. The river is fed by magnificent waterfalls and is channeled through gorges out into the tropical rain forest where there are more species of birds than anywhere.

Surveying Costa Rica's Monte Verde preserve, which contains some 200 varieties of trees, including 300-ft. oaks. Animal life includes deadly scorpions; army ants; and plumed quetzals, sacred bird of the Maya civilization.

The first of the series takes us back to the 13th Century to explore medieval superstitions of ancient "naturalists." Frederick II of Hohenstaufen had a passion for falconry that resulted in his immense illustrated book De Arte Venandi Cum Artibus (On the Art of Hunting With Birds.) Series host is Dr. Donald Johanson, noted paleoanthropologist and director of the Institute of Human Origins in Berkeley, California.

Theologians and clerics in the 17th and 18th centuries were among the first to study animal behavior. John Ray began in the 1600's to catalog "the work of the Creation," starting with plants and later including birds. Sir Francis Willoughby continued this work. Rev. Gilbert White studied bird songs, Charlie LeRoy experimented with wolves and deer, and Charles Waterton wrote about jungle animals.

In 1848, Charles Darwin began the quest to understand the mysteries of the animal mind. Following Darwin's achievement - suggesting a plausible process for evolution: natural selection - Lewis Henry Morgan discovered evidence of cogitation in beavers. George Romanes experimented with fish, cats, and dogs, Douglas Spalding with newborn chicks, all finding apparent mental activity. Meanwhile Jacques Loeb attempted to prove animals "mindless."

First there is a re-creation of Ivan Pavlov's experiments which led to the discovery of the "conditioned reflex." Then we see the investigation by Otto Pfungst of "Kluge Hans" (Clever Hans) a horse whose apparent knowledge of arithmetic was actually response to subtle signals from his trainer. We also see dramatizations of Thomdike's experiments with chicks, Watson's with terns, and B. F. Skinner's famed work at Harvard in the thirties.

Continuing with the exploration of animal communication we see recreations of Karl von Frisch unraveling the language of honey bees. Julian Huxley, who discovered a possible language in the ritual movements of great-crested grebes, Konrad Lorenz who recorded the visual language of geese, and Niko Tinbergen, who studied the habits of hunting wasps and together with Esther Cullen recorded the relationship of temperament in birds to their habitat.

Scientists have long attempted to discover why animals rarely live alone. Animal society seems to be based on despotic rule by the strongest, tempered by the powerful attractive forces of sex. Portrayals of Thorlief Schjelderup-Ebbe, Solly Zuckerman, Clarence Ray Carpenter, Frank Fraser Darling, William Hamilton, and Amotz Zahavi, show the contributions of each of these men towards understanding the puzzle.

Two distinct marine worlds meet in the waters that encircle Australia. In its long voyage into isolation following its breakaway from Gondwana, 45 million years ago, the island continent came to span both tropical and temperate seas. Today its shores are ringed by the most diverse assemblies of marine life on earth. This program recounts the making of this unique Australia down under, from the storm tossed kelp forests of the cool south, to the magic splendours of the Great Barrier Reef. The program begins its story where Australia was born, in the southern latitudes of the Antarctic seas. Antarctica is the last remnant of Gondwana - it froze over after the other continents broke away, but its cool rich waters still generate a wealth of nutrients which, carried by the deep currents, sustain Australia's marine life.

A koala up a gumtree is the classic image of the Australian bush. How that odd partnership evolved is one of the strands woven into this episode of Nature Of Australia. The program tells the story of how the island continent's wooded margins came to be dominated by one unique type of tree growing in a great variety of forms - the eucalypt. The nursery for nearly all life in Australia is the rainforest, of which only a few patches remain today - th last remnants of vast, dense forests that covered Australia when it first broke away from the ancestral super-continent of Gondwana, and voyaged north into isolation. From among its proliferation of plants emerged the eucalypts, the characteristic gum trees - and from among the forest animals arose a great and varied company of marsupials, adapting to every kind of environment that evolved in response to Australia's changing, drying climate.

Australia's arid interior is often called the dead heart. In fact, it teems with life, supported by a hidden network of buried rivers recharged by rare but heavy rains. This episode tells the story of this surprising desert - formed when the climatic change overtook and dried out central Australia. What was once a land of vast lakes and broad rivers turned into a parched region of glittering stone and burning sand, interwoven with swathes of hardy woodland and plains of desert grass. A great variety of plants and animals has adapted to life in the arid centre, with its swings between the brief good condition that follow the unpredictable rains, and then long periods of drought. It's the land of the lizards - from giant goannas that sniff out snakes hiding under the sand, to the tiny, delicate Lake Eyre dragons who've made the desolate saltpans their domain.

Australia's northward drift slowed down when it collided with Asia about 15 million years ago - in the upheavals, chains of islands were thrust up and eventually they became the stepping stones for an invasion that would change the face of Australia. With the arrival of the first humans - at least 50,000 and possibly as long as 120,000 year ago - a new force entered the continent to shape the fortunes of its plants and animals. The first landfall was on the far north coast of Australia, a rich and tropical region ruled by the annual monsoonal rains. This program tells the story of Australia's top end, where the first Aboriginal people arrived, settled, and perfected the use of fire as a means to manage the landscape.

Modern Australians want to recapture the Aborigines ability to live harmoniously with indigenous plants and animals.
