Typical gadfly petrel with long, angular wings, long tail, and strong, banking flight. Smaller than Cory's shearwater, which could be confused for Fea’s at a distance. Very similar to Zino's Petrel, but slightly larger and longer-winged, and has a longer and heavier bill and a less “cute” head. As in Zino's Petrel, underwing is mainly dark, underparts are white, and hood is gray with darker eye-surround. Upperparts gray with darker W-shape across wings and mantle. Breeds on several East Atlantic islands. Forages at sea.
