Scary sound of European nightjar. Are you afraid of the dark? 

The European nightjar feeds on a wide variety of flying insects, including moths, beetles, mantises, dragonflies, cockroaches and flies. It will pick glowworms off vegetation. It consumes grit to aid with digesting its prey, but any plant material and non-flying invertebrates consumed are taken inadvertently while hunting other food items. Young chicks have been known to eat their own faeces.
Birds hunt over open habitats and woodland clearings and edges, and may be attracted to insects concentrating around artificial lights, near farm animals or over stagnant ponds. They usually feed at night, but occasionally venture out on overcast days. Nightjars pursue insects with a light twisting flight, or flycatch from a perch; they may rarely take prey off the ground. They drink by dipping to the water surface as they fly. Breeding European nightjars travel on average 3.1 km (3,400 yd) from their nests to feed. Migrating birds live off their fat reserves.
