Prof. Sam LawlerC.A. Adams: nightjars are commonly seen foraging under lights at night, but is this normal behavior? Obs. bias? They nest on the ground and rely on camouflage [and being cute, probably], so might be very sensitive to artificial light.
It appears they avoid urban areas, lights don't seem to statistically help them forage and do make predators more effective against them.
