Word of Mouth - 06/04/2010

In this week's edition of Word of Mouth Michael Rosen explores the language of the natural world asking if words are up to the job of conveying the complexities of nature. He also finds out how some British birds got their names and hears the story of a mushroom whose hallucinogenic qualities are used to capture flies. So join Word of Mouth, gathered around the nature table, this afternoon at four o'clock.
