This episode tells the incredible story of four Second World War British POWs who overcame the trials and tribulations of internment through a shared passion for birdwatching. Derek Niemann, a specialist in natural history and author of Birds in a Cage, joins Dan to discuss why this obsession helped them survive the POW camps, and how it drove them to become giants of post-war British wildlife conservation. Produced by Hannah Ward and edited by Dougal Patmore.
