Listen to the sounds of nature on a ramble along the River Usk

Listen to the song of the River Usk in autumn as you follow editor Fergus Collins on a gentle ramble through a recently flooded landscape to find wildfowl, waders and other creatures. Plus, discover a blood-soaked story of treachery hidden in a peaceful riverside earthwork.

This is the last of the series in season 4. We'll be returning with more podcasts in January 2020.
