Résumé
Chris Packham, Michaela Strachan and Iolo Williams bring a seasonal sound spectacular with this music-free episode, designed to showcase the natural sounds of winter. There's a look at why a bird's vocal repertoire is much more than just its song, how bees are coping with changing winters and how a man discovered a family of otters on his local nature reserve and made it his mission to capture their magical moments.
