The Caprimulgiformes are a clade of mostly very aerial birds, uniting the ‘Caprimulgiformes’ as historically recognised with the phylogenetically embedded Apodiformes. Members of the clade are united by possession of a greatly elongated leg (crus longum) of the ulnar carpal bone (Mayr 2009). All members of the traditional Caprimulgiformes are crepuscular or nocturnal birds with wide beaks, a large gape, and soft cryptically-coloured plumage, that feed on the wing (most are insectivores; the oilbird Steatornis caripensis is frugivorous). Apodiformes have lost some of these characters, but still feed on the wing. Morphological support for the total group of Caprimulgiformes (including Apodiformes) is, however, uncertain.

Within the Caprimulgiformes, the Caprimulgidae include the nightjars. Nightjars have relatively short toes with the middle toe pectinate (Sclater 1866a). The family has historically been divided between subfamilies Caprimulginae and Chordeilinae based on the presence of strong rictal bristles around the mouth of the former, but this division has not been supported by recent phylogenetic analyses. Instead, the eared nightjars of the genus Eurostopodus represent the most basal members of the Caprimulgidae; these large Australasian nightjars lack rictal bristles and possess more or less developed ear tufts. Lurocalis is a Neotropical genus of nighthawks lacking rictal bristles with a relatively short, square tail (Sclater 1866a).

The Steatornithidae are represented in the modern fauna by a single species, the oilbird Steatornis caripensis of northern South America. This large bird, reddish-brown with white spots on the nape and wings, nest colonially in caves, using echolocation to find their way in the dark. The Fluvioviridavidae are wide-billed, fossil birds known from the Eocene of Europe and North America. The Archaeotrogonidae of the Oligocene of Europe were originally described as relatives of the trogons but later regarded as more similar to caprimulgids.
