A series of six programmes on communicating 2:Animal Talk
Like humans, animals depend on communication for reproduction, and often for a complex social life. But the methods they use are widely different, because their sense organs work in a variety of often surprising ways.
Using fishes, snakes, dogs and ducks Professor David Pye explains how some animals can communicate with 'sounds' and 'colours' that we cannot hear or see. Sometimes man can even communicate with his domestic beasts. Assistant producer MICHAEL GUNTON Producers
