Episode 11: The Discovery of Animal Behavior: A Question of Learning
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.
Episode 13: The Discovery of Animal Behavior: Living Together
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.

Gilbert White studied bird songs, Charlie LeRoy experimented with wolves and deer, and Charles Waterton wrote about jungle animals.

Episode 3: The Flight of the Condor: Down the Amazon
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.
Episode 2: The Flight of the Condor: Ocean, Desert, and Thin Air
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.
