The European nightjar, Eurasian nightjar or just nightjar (Caprimulgus europaeus) is a crepuscular and nocturnal bird in the nightjar family that breeds across most of Europe and temperate Asia. The Latin generic name refers to the old myth that the nocturnal nightjar suckled goats, causing them to cease to give milk.
