From Wikipedia, the free encyclopedia
Nightjars in the colloquial sense refers to a group of birds with dull plumage which hide during the day and often have striking calls. They are actually a number of groups which includes the true nightjars and nighthawks as well as the related eared-nightjars in the Caprimulgiformes, and the owlet-nightjars in the Aegotheliformes which recently have been verified as distinct.
