( Swift)
Nearly 20, see text. The swifts are a family, Apodidae, of highly aerial birds. They are superficially similar to swallows but are actually not closely related to those passerine species at all; swifts are in the separate order Apodiformes, which they share with the hummingbirds. The treeswifts are closely related to the true swifts, but form a separate family, the Hemiprocnidae. The resemblances between swifts and swallows are due to convergent evolution reflecting similar life styles based on catching insects in flight. The family scientific name comes from the Ancient Greek ap???, apous, meaning "without feet", since swifts have very short legs and never settle voluntarily on the ground, perching instead on vertical surfaces. The tradition of depicting swifts without feet continued into the Middle Ages, as seen in the heraldic martlet.
