Jarvis Cocker is back with a new series of Wireless Nights

Tonight, armed with a bat detector Jarvis sets off through a wetland in search of bats and bat stories.

He finds ecologist John Altringham crouched beside a cave in North Yorkshire awaiting a swarm of bats that come once a year to dance the night away.

Jayne Hyde Dryden is using her powers of echo location to find her way around on a night walk. Being blind, this helps her see in sound.

And Gail Armstrong is on watch at the Bat Hospital in Lancashire, nursing injured bats back to good health and finally returning them to the wild.
