Environmentalist Tony Juniper recalls catching a whitethroat in a mist net in Portugal which had been ringed in Dorset and listening to their song as part of the soundtrack of summer. Tweet of the Day has captivated the Radio 4 audience with its daily 90 seconds of birdsong. But what of the listener to this avian chorus? In this new series of Tweet of the Day, we bring to the airwaves the conversational voices of those who listen to and are inspired by birds. Building on the previous series, a more informal approach to learning alongside a renewed emphasis on encounter with nature and reflection in our relationship with the natural world.
