The cave swiftlet is a small bird from the swift family. It lives in Southeast Asia caves, builds nests from its own saliva, and uses echolocation to fly in complete darkness.
The cave swiftlet differs from other swifts by its echolocation ability and building nests only from saliva on cave walls. It is important for nature because its droppings feed many cave animals, and the nests are used by humans as food.
