Large gray-and-white songbird with a long tail, curved bill, black mask and mustache, and dark blotches on the underparts. Endemic to Galálapagos. Found only on the southeastern island of Española, where it is the only mockingbird. Very inquisitive and has almost no fear of people. Lone birds or small groups race around beaches boldly inspecting almost everything they encounter including shells, sea lions, cameras, and shoes. Often perches up on bushes or rocks.
