Order: Caprimulgiformes


Nightjars, Frogmouths, Potoos, the Oilbird, Swifts, Treeswifts and Hummingbirds.


Caprimulgiformes is an order in the class Aves.

Recent results show that the former order Apodiformes is embedded within Caprimulgiformes. There were three possible solutions:

  • 1 Transfer Owlet-nightjars to Apodiformes,
  • 2 Make a new overriding taxon that contains Apodiformes and Aegothelidae, OR
  • 3 Embed Apodiformes within the nightjars (Caprimulgiformes)

Clements choose the last solution and the Opus follows.

Order Caprimulgiformes viewedit
Podargidae Frogmouths
Caprimulgidae Nightjars and Allies
Nyctibiidae Potoos
Steatornithidae Oilbird
Aegothelidae Owlet-nightjars
Apodidae Swifts
Hemiprocnidae Treeswifts
Trochilidae Hummingbirds
