Discovery Chronicles Extreme Birdwatching: Measuring Change on a Galápagos Island

A treasure trove for science classrooms, citizen scientists, and budding biologists, this “you-are-there” account of a landmark study of wild finches going about their finch-y business captures the scientific process in action. Daphne is an island. Not one you’d choose for a vacation. There are no sandy beaches, resorts, hotels, or houses. No tall trees to make shade. The steep, rocky sides of a volcanic Galápagos island are not inviting, and most who visit this part of the world sail right past. But Peter and Rosemary Grant are not most people. A husband-and-wife team, the Grants came to this singular place with a singular goal: to study two species of wild finch. For decades, the scientists and their students counted, cataloged, and observed finches on a remote mile-wide island. Through teamwork, painstaking observation—extreme bird-watching, extreme plant study, extreme seed counting—and careful beak measurements, the group of committed scientists proved step-by-step, over forty years, how finch beaks change in response to their environment. Weaving accessible biology and the scientific process into an inspiring conversational narrative, this second title in the Discovery Chronicles series—packed with resources and back matter—concretely honors the value of hard journeys, the vision and ambition behind tedious tasks, and the astonishing power of curiosity.
