This episode concentrates on the hidden treasures of winter. Chris Packham comes live from the New Forest, catching up on the drama showing up on the live cameras at his badger sett and the spawning salmon in the River Ness . He also takes a look at the reasons why waders bob. Iolo Williams has eyes on the very rare white-fronted geese that migrate to Wales every year, while Gillian Burke is pond dipping at RSPB Old Moor in South Yorkshire – as well as looking at the area's dragonfly species . Michaela Strachan is on the tracks of the winter residents of Tentsmuir, hoping to see evidence of some of our favourite mammals. Meanwhile, on the Orkney Islands, a regular beachcomber is hoping the winter tides will turn up some natural treasures, and we’re on the hunt for the elusive woodcock in Northern Ireland.
