Bats

Bats are in particular affected by artificial light. It’s known for a long time that bats like to hunt around streetlights. This is because of the accumulation of insects around these lamps, which are relatively easy to catch. Especially the common pipistrelle makes use of this food source. However, most species of bat shy away from light, and light potentially compromises their chances on survival and reproduction. Possibly, different colors of light have a less severe impact on the life of bats.
In the Lightonnature project, we study the effects of light on hunting activity of bats, and how successful bats are in catching prey around streetlights. We also study the effects of light on roost choice.

Bats may choose different spots to roost if there's artificial light present

Bats of the Myotis genus, like this Natterer's bat (Myotis nattereri) strongly avoid light (photograph: Kamiel Spoelstra).
