Nightjars are found throughout North America and Europe, from Mongolia and Northwestern China to North America.
They are medium-sized nocturnal or crepuscular birds in the family Caprimulgidae, characterised by long wings, short legs, and very short bills.
They are sometimes called goatsuckers or bugeaters, due to the ancient folk tale that they sucked the milk from goats or their primary source of food being insects.
Some New World species are called nighthawks.
The European nightjar ( Caprimulgus europaeus ), common goatsucker , Eurasian nightjar or just nightjar , is a crepuscular and nocturnal bird in the nightjar family that breeds across most of Europe and the Palearctic to Mongolia and Northwestern China.
