Summary: Brett Westwood presents. Saving Species is in London looking for south-bound migrating birds. Ornithologist Ian Wallace has watched the skies wherever he’s lived since he was a young man, including London’s Primrose Hill. So how would his earlier findings compare with todays visible migration? And we'll have a special piece from a sacred forest in Ethiopia, a unique wooded island refuge in a desert of over tilled land - a forest protected by a church and its followers. We hear from Claire Ozanne from Roehampton University as she and colleagues conduct the first ever wildlife survey of this refuge.
