Chris Packham and Michaela Strachan dig a little deeper into the behaviours seen on the live nest cameras at RSPB Arne in Dorset, as well as covering the topical wildlife stories of this season. Megan McCubbin has travelled down to a quarry on the Isle of Purbeck to find out why this location is so important for bats, and Gillian Burke is continuing her exploration of Anglesey, where she’s looking at the spring behaviours of the tern. Plus an 81-year-old man who’s made it his mission to save the swift.
