15/30 Butterflies and swifts are the subject of this weeks Saving Species, presented by Brett Westwood. The Wailing Wall in Jerusalem is the oldest known nesting site in the world for the common swift but numbers are falling there and elsewhere - why and what is being done to help? Find out more about swift towers and chick rescue schemes as conservationists battle to help save them. And Brett discovers more about the private life of the beautiful woodland butterfly the Silver Washed Fritillary, a specialist woodland species that brightens any shady glade. Brett also gets an update on Chris, the Saving Species cuckoo that is making its way to its wintering area in Africa. The first time ever cuckoos have been tracked on their epic journey, helping us understand more about this icon of spring.
