The dramatic landscape of Western Iberia in Portugal where the Côa river is carving its deep path through the mountains is home to a vast variety of wildlife. Animal species of all sizes, shapes and colors inhabit land, skies and waters of the Côa Valley, however a great number of them are hard to spot. Anyone can see large herbivores from afar, but many other species are only visible through lenses of wildlife cameras – the invisible eyes in the wild.
