Iguazú

Description: The Iguazú river flows through Brazil and Argentina and in the border its waters fall dismally. The Iguazú Falls split the horizon in an enormous and magnificent abyss. This ocean plummeting in torrents seems harsh and inaccessible but it shelters the great dusky swift. In its relentless flight, this bird crosses the waterfall at high speed to seek shelter and nest on the vertical rock behind the wall of water. Unfortunately, dams and climate change sometimes diminish the river’s torrent. The swift will have refuge only if the Iguazú river keeps flowing abundantly.
