Heavyset, gray-brownish seabird of the open Pacific Ocean, with pale patches in the underwings at the primary feathers and indistinct pale feathering around the bill base. Upperparts sometimes show grayish, almost silvery grizzled appearance. High-arcing flight in high winds, as in other gadfly petrel species. Similar to dark-morph Kermadec Petrel, which shows white shafts in primary feathers in the upperwings, lacking in Providence.
