A series on some extraordinary facets of the animal world. with Tony Soper
2: Signs and Signals
Some birds sing, others flash colours, buffalo and cats make perfumes. All are ways of passing messages. What do birds and beasts have to talk about and how have their languages evolved? Can we ever hope to be like Dr Dolittle and talk to the animals?
