\"Great Shearwater,\" Wikipedia, the free encyclopedia.This shearwater is 43–51 cm in length with a 105–122 cm wingspan. It is identifiable by its size, dark upperparts, and underparts white except for a brown belly patch and dark shoulder markings. It has a black cap, black bill, and a white \"horseshoe\" on the base of the tail. The stiff flight, like a large Manx shearwater, is also distinctive. The only other large shearwater in its range is the all-dark sooty shearwater.
