Category:Apodiformes
Traditionally, the bird order Apodiformes has three families: the swifts (Apodidae), the tree swifts, (Hemiprocnidae), and the hummingbirds, (Trochilidae). New research shows that the owlet-nightjars seem also to belong in this order.
In the Sibley-Ahlquist taxonomy, hummingbirds are separated from the Apodiformes as a new order Trochiliformes.
