An insight into how a seventh-century saint became the first avian protector when he realised feathers kept him warm at night, and how a group of `ornithological suffragettes' changed women's fashion - and saved Britain's birds. Plus, the role of the creatures as tourist attractions. Narrated by Bill Paterson with contributions by Bill Oddie, David Attenborough, Tony Soper, Kate Humble, Helen MacDonald and Robert Lambert.
