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.
Behavior
Distribution and status During the breeding season, the petrels forage in waters surrounding Isla Alejandro Selkirk and Isla Robinson Crusoe (both islands in the Juan Fernández Archipelago), as well as coastal Chile. The birds can be found in flocks with pink-footed shearwaters and other seabirds. During the non-breeding season, the petrels forage in the equatorial currents and counter-currents, as far north as the Hawaiian Islands.
