Bats and light

Which are af­fected?

BBC Wildlife Magazine - - News Feature -

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.
