We went to the region of Los Rios to meet Kika Silva, in a new adventure of The Ark Project. In this episode we will accompany a group of scientists who are doing important work in the Río Cruces Wetland to protect its fauna. We will go after the osprey, a very difficult bird of prey to spot and which, in itself, is a visual spectacle. And at the National Zoo, we will learn the story of Yogi, a bear with glasses, the only one in South America, who must be clinically operated on.
