1/3. TV's pioneering natural-history presenters are profiled in documentaries that illustrate how the passion they possessed for their work resulted in ground-breaking footage of wildlife. This first instalment looks back over the careers of two broadcasters whose fun-loving approach has inspired many would-be naturalists: Johnny Morris , whose Animal Magic ran for over two decades on BBC1, and Bill Oddie, who went from being a comedian in The Goodies to passionate bird-watcher.
