It is the fastest-flying bird in flapping flight, with confirmed speeds reaching 111.6 km/h (69.3 mph). It is commonly reputed to reach velocities of up to 170 km/h (105 mph), though this has not been verified.
These birds have very short legs which they use only for clinging to
vertical surfaces. They build their nests in rock crevices in cliffs or
hollow trees. They never settle voluntarily on the ground and spend most of their lives in the air, living on the insects they catch in their beaks.
