Mr. Kilner’s Biology class visited las Marietas Islands to continue their Ecology collaboration with the scientists from the Comisión Nacional de Áreas Naturales Protegidas (CONANP). During a fun and tiring day, the students identified and took population data on birds such as Brown and Blue Footed Boobies, Pelicans, Gulls, Magnificent Frigatebirds and several species of Tern. In the second part of the day the focus turned under the ocean surface where the class snorkeled and were able to identify coral species, and many species of fish including King Angelfish, Trumpetfish, Pargo and Giant Damselfish. On returning to the lab, the class have been producing scientific journal standard reports of their findings. We are extremely privileged to have this level of access to the Marietas and the dedicated scientists who care for their wildlife.
