Size is 9 to 12 inches. Rather scarce in Canal area. Found on Coiba, Taboga, and Perlas Islands. Ranges from Mexico to Bolivia, Northern Argentina and Southern Brazil. Feeds in early morning and late afternoon. Often eats prey on the wing. Also flies among swifts and disguises itself as a swift to possibly ambush its prey.
