Episode 3 - S9.E3

This episode concentrates on the sense of winter – the touch, smell, sounds and sights that make up the most magical of seasons.

Chris Packham is in the New Forest, examining the species of bee you might find in your hotel at the moment, as well as taking a look at different shapes of nest. Meanwhile, Iolo Williams inspects some tree creepers, and Gillian Burke ventures into Sheffield to see some of the wildlife that populates the city - dippers, salmon and mandarins are all on her to-see list.

Michaela Strachan looks at some of the strategies animals employ when they hibernate, while wildlife cameraman Richard Taylor Jones tells us the story of the Oare Marshes on the River Swale, which have been transformed from a gunpowder-making site to a wildlife haven.

Also, fish enthusiast Jack Perks gets into some extraordinary camouflage to witness a bait ball in Rutland Water.
