Natterer's bats roosting in a repaired mortice joint in barn

This short video shows that Natterer's bats can use a repaired mortice joint in an old timber framed barn in the UK.

I have a Sony HDR-SR10E which has O lux night shot. You don’t need Super night shot which doesn’t work for filming emerging bats in the dark. You ALSO need a separate Infra Red light source - preferably one which can diffuse the light. I have recently bought two IRLamp6 from Bat Conservation & Management in the States which are excellent but they are very expensive. This set up has not disturbed these bats as filming took place in total darkness.
