Species notes
Overview
Named for Juan Fernandez Islands in Chile, where the species breeds. Main identification features are relatively large size, gleaming white underparts with small black “comma” on bend of underwing, and dark cap blending into gray of hindneck. Upperparts show darker “M” pattern common to many petrels. Much larger than Masatierra Petrel and other small petrels.
