In the afternoon we drive a few hours to an excursion in the Medio Queso wetland. A beautiful large freshwater marsh, where the local guide can find very special species. Very small rails that you would never see yourself. At the end of his tour he finds 5 species with the help of playing the tunes of the certain species while the boat is stuck in some bushes. Very effective. He has been doing it for 10 years says our guide.
