A natural history of behaviour by David Attenborough
The love song of a fish keeps people awake in San Francisco bay. At dusk in Malaysia the riverbanks twinkle with the flashes of millions of tiny beetles. The world's loudest birds scream through the rainforest. This week David Attenborough talks to the animals in a global look at methods of communication.
