As week three of Springwatch begins, the excitement from the nests is palpable. With plenty of fledglings, Chris Packham and Michaela Strachan are keeping up with the comings and goings at RSPB Arne in Dorset. Megan McCubbin is revelling in a botany bonanza at Durlston Country Park, a national nature reserve on the Isle of Purbeck, which in the spring is simply buzzing with life. Meanwhile, Gillian Burke heads to Anglesey, where she immerses herself in a woodland where red squirrels roam.
