In this episode, Winterwatch takes a look at wellbeing – both for humans and for animals – and how, in these difficult times, nature can have the answers. Chris Packham is live in the New Forest with all the news from our live cameras. Iolo Williams is at the Centre for Alternative technology in Wales. Gillian Burke is at RSPB Old Moor in South Yorkshire, looking at how nature can be a benefit to our mental health. Michaela Strachan ventures further afield in Scotland, hoping to catch sight of the Dunsapie otter in Edinburgh. In her third film about unloved animals, Megan McCubbin discovers the deep intelligence of pigeons and why we should admire them. Plus a look at wild-swimming with a woman who has found it of enormous benefit to her mental health, and who also takes amazing photographs of the wildlife she sees on her swims.
