It's a hot midsummer day and sunlight sparkles along a stretch of gentle rapids on the River Usk. On the riverbank, floods have carved small cliffs enticing a colony of sand martins to create a stronghold. The birds sally forth to hunt insects – chattering as they go.
BBC Countryfile Magazine's Sound Escapes are a weekly audio postcard from the countryside to help you relax and transport you somewhere beautiful, wherever you happen to be.
Recorded by Fergus Collins, introduced by Hannah Tribe.
