It’s time to sit back and enjoy nature as it was intended. With a music-free episode, the audience will be immersed in the natural sounds of nature. Chris Packham and Michaela Strachan catch us up on the latest wildlife news from RSPB Arne in Dorset. Iolo Williams ventures across the water and onto Brownsea Island with a thermal camera to capture all the island’s drama after dark. We meet two families of otters who inhabit our most northerly islands and must take to the seas to find a feast, and Gillian visits Sanday, the largest of Orkney’s northern isles, to lay eyes on a mammal found nowhere else on earth.
