The Apodidae, or swifts, form a family of highly aerial birds. They are superficially similar to swallows, but are not closely related to any passerine species.

Apodiformes are unique in having shallow ball and cup sockets connecting the coracoids to the sternum. The humerus, radius, and ulna are all relatively short, but the carpal bones are exceptionally long. The total length of the "hand" bones is nearly twice that of the "arm" bones.

Swifts are in the order Apod­i­formes, sub­or­der Apodi and fam­ily Apo­di­dae. There are two sub­fam­i­lies of swifts: 13 species of Cypseloid­i­nae (prim­i­tive Amer­i­can swifts) and 79 species of Apo­d­i­nae (swiftlets, spine­tails and typ­i­cal swifts).

Apodiform - Migration, Nocturnal, Gliding: Distribution of swifts and hummingbirds is influenced by the specialized nature of their foods. Swifts are found virtually worldwide. Apodiforms are among the few bird groups that conserve energy by reducing body …

Birds in the swift family (Apodidae) eat, mate, and sleep in the air. These birds, also called typical swifts, have long, pointed wings. Their head-to-tail length ranges from 3.4 to 9.6 inches (9 to 25 centimeters).
