Bats and light
Which are affected?
All UK bats have good eyesight as well as a very sophisticated echolocation system, but lighting impacts them in different ways.
Slower flying, broadwinged species – such as the brown and grey longeared, greater and lesser horseshoe ( pictured) and several Myotis bats, including Daubenton’s – are strongly averse to white or green light, and may also be more vulnerable to night-vision hunters. But the full impacts of red light are not clear.
