Swifts
Order: Apodiformes Family: Apodidae
The swifts are small aerial birds, spending the majority of their lives flying. These birds have very short legs and never settle voluntarily on the ground, perching instead only on vertical surfaces. Many swifts have very long swept–back wings that resemble a crescent or a boomerang. There are 98 species world wide, and 9 North American species.
