Naturalist and TV presenter Mike Dilger keeps a promise to actress Alison Steadman as she prepares to start filiming a new series of Gavin and Stacey and takes her to experience the wildlife at the RSPB's reserve at Minsmere. We also look at how to get the best out of a visit to an RSPB reserve and our Great Moment with Nature feature looks at one of the noisiest of our summer visitors - the swifts - with a plea to report sightings as their numbers are on the decline and statistics are vitally important to find out why. Join Jane Markham for this episode of Nature's Voice.
