Large, spectacular swift, seen singly or in small groups (up to 10 birds). Favors drier mountain and foothill areas, often near cliffs, but ranges widely. Rarely associates directly with other swifts. Flight is fast and graceful with long sweeping glides and deep wingbeats. Long, forked, swallow tail is usually held closed in a point. Note the size, shape, and contrasting white throat set off by a black body and cap.
