Episode 3

Live from their base in the heart of the Cotswold Area of Outstanding Natural Beauty, Chris Packham and Michaela Strachan share the latest news from the wildlife cameras over the past 24 hours, with reports on the blue tits and a new nest, the mandarin duck.

Steve Backshall is upping the ante with his latest mission, climbing one of the state's ancient, or veteran oaks, in order to see what he can find, and to spend the night at the top of it.

Gillian Burke has arrived in a different part of Shetland where she catches up with a special family of otters - including some intimate moments rarely caught on camera.

We have the latest update from the raven family on the Gower, and a film about one incredible species of slug - the tree slug - which climbs up into the canopy every night to feed. Chris Packham in particular is a fan, and exhorts viewers to join his new slug appreciation society.
