Panorama captured at Parque Nacional Iguaçu. The water flow was just perfect: enough intense for the falls to be insanely powerfull, but not too intense to compromise the camera.

A flock of Cypseloides senex moves randomly, changing shapes and density. The dynamic spectacle takes place in a mindblowing scenery: the very heart of Iguaçu National Park.

Impressively, these fantastic birds make their homes behind the falls. So as to arrive (or leave!) home, they have to assume the shape of a sharp arrow and cross the dense water curtains.
