Armed with a field guide and a half-decent pair of binoculars, Charlie Elder travels the length and breadth of the British Isles to spot forty bird species in serious decline - the UK’s Red List. He looks at why their numbers have fallen, what efforts are being made to encourage their recoveries and meets experts and enthusiasts who are working to make a difference. He also examines just why birds matter in the first place and considers the role of the birdwatcher - one species that is certainly not in decline.
