Overall student winner: Waterfall Swift

Caption

Like most of Swift's species, the Great Dusky Swift (Cypseloides senex) can be found perching in vertical cliffs. But, this particular species takes its habitat to the extreme and, being known in Latin America literally as "Waterfall swift", Great dusky Swifts are found in the steeps rocky walls of up to 80 meters high around the Iguazú falls, frequently flying through the waterfalls offering a unique show.
