The currrent bio-chronic states an educational experience, with a group of school students from the coastal city of Los Vilos, in the Coquimbo region, Chile. During a year, five girls among 11 and 12 years old, were part of an ornithology work, which wanted to develop the capacity of observing, recognize and value birds that belong to their near environment, with the aim of generating scientific skills and respectful behavior towards coastal wetlands with different types of protection and ecological relevance. It was evident a very strong comminment and enthusiasm in students, which allowed to assimilate enough knowledge about reproduction and migration of the birds studied. It allowed students to get involved in environmental events and scientific school works, interacting with other school fellows and searchers in the ornithology and preservation fields. Implications about this experience is discussed, in relation with the role that the school ornithology may take part in the accomplishment of the learning objectives according to the curricular syllabus for primary school in Chile.
