The bird genus Apus comprise some of the Old World members of the family Apodidae, commonly known as swifts.
They are among the fastest birds in the world. They resemble swallows, to which they are not related, but have shorter tails and sickle-shaped wings. Swifts spend most of their life aloft, have very short legs and use them mostly to cling to surfaces.
