In this episode of Saving Species we look at one of Britain's favourite birds - the swallow. Ed Drewitt travels to a swallow roost in Southern England, where overnight he joins the The Wetland Trust to trap and ring swallows as they gather in a mass roost to head south. So how have the swallows and other summer migrants done this year?
Chris Sperring travels with entomologist Tristan Bantock to a central London park to track down the rare mediterranean Southern Oak Bush Cricket was first recorded in the UK in 2001. Since then sightings of the bright green, wingless cricket have become more frequent, but still more elusive than its native counterpart.
David Robinson from the Department of Environment, Earth and Ecosystems at the Open University joins Brett Westwood in the studio to discuss in more depth how the Southern Oak Bush Cricket came to be in the UK.
