Dark ash-gray petrel of cold southern seas. Small- and stout-bodied overall, but with a large, “puffy”-looking head. Note underwing patterning, with a pale “shoulder” separated from pale-based primaries by a broad, diffuse dark bar. Flies quickly and strongly, often arcing up to impressive heights above the waves on angled, sharply kinked wings. Can be difficult to distinguish from other dark medium-sized petrels at a distance, but note pale patches under the wings, overall gray body coloration, relatively large “cute” head, and flight style. Often forages at night. Nests in loose colonies on the Prince Edward, Crozet, and Kerguelen Islands, as well as Gough Island.
