Shearwaters are wide-ranging world travelers. This is a Buller’s Shearwater. The only known nesting area for these birds is on some islands near New Zealand. In May, at the end of their nesting season, Buller’s Shearwaters disperse as far as Japan and the coast of Alaska. By September, some of them have already returned to New Zealand. They are 16 inches long with a 38-inch wingspan.
