BBC1_Countryfile_ Worcestershire 2Jul17 - lesser horseshoe bats at Worcester Cathedral <br /> <br />Worcester Cathedral is home to a very rare population of lesser horseshoe bats, thought to be the only urban population in the country. At this time of year, the summer roost is full of females gathered together to give birth and raise their young. Along with an army of volunteers, Ellie ventures out after sunset. Positioning themselves around the roost, along the River Severn and into the suburbs beyond, they use bat detectors to discover where the bats are going. <br /> <br />Cody Levine: Principal Ecologist at Worcestershire County Council <br /> <br />Mike Glyde: Secretary of Worcestershire Bat Group
