The even-tailed nightjar is a small nocturnal bird from the nightjar family. It lives only in Brazil, flies at twilight, and catches insects directly in the air.
The even-tailed nightjar differs from related species by its completely even tail without white stripes or notches. It is beneficial to nature because it destroys a large number of insects every evening.
