Apodimorphae is a clade of strisorean birds that include the extant families Trochilidae (hummingbirds), Hemiprocnidae (treeswifts), Apodidae (swifts), Aegothelidae (owlet-nightjars), and many fossil families. This grouping of birds has been supported in a variety of recent studies.[1][2][3][4][5][6] There are two higher classification schemes that have been proposed for the apodimorph families. One is all strisorean birds are classified in the order Caprimulgiformes,[3][5] while the other is the strisorean birds are split into several distinct orders. In this case Apodimorphae is a subclade of Strisores that includes the orders Aegotheliformes (only including the owlet-nightjars of Australasia) and the Apodiformes (the swifts, treeswifts, and hummingbirds which have a global distribution).[2][4][6]
The name Daedalornithes[1] is also been used for the owlet-night-apodiform clade. Daedalornithes and Apodimorphae have different definitions. Daedalornithes is defined as the crown group (the least inclusive clade including Aegotheles cristatus and Apus apus)[6] whereas Apodimorphae referring the total-group (the most inclusive clade including Aegotheles cristatus and Apus apus but not Caprimulgus europaeus, Steatornis caripensis, Nyctibius grandis, or Podargus strigoides, a definition that includes fossil lineages more closely related to Daedalornithes than they are to other Strisores)
