Cogswell 1949 Puffinus balleri July 4- Pt. Pinos, Monterey Co., Calif. A single individual seen repeatedly (or different ones?) from the N. side of the Point about 7:00 - 7:30 PM. Its white underparts, light gray back, dark brown flight feathers & upper secondary coverts and dark tail all noted. The light tone of its upperparts was very noticeable in comparison with the dark [illegible] of the abundant P.griseus & even with the dark upperparts of P.opisthmelas. In size it was compared directly only with P.griseus, & seemed but slightly smaller. It was seen first about 7:00 PM, & thereafter at circled around for some time to the N. of the point. when flapping against the wind it seemed to have about the same speed of wing stroke as P.griseus, but it sailed higher between flap series - sometimes even "hanging" on the breeze at 15-20 feet above the water (something P. griseus never seems to do) for several seconds. Going downwind it seemed to travel less rapidly, but with typical shearwater grazing of the water surface between swells. It is definitely the same sp. as I saw in the central Pacific commonly in Nov. of 1945 - easily picked out because distinctly marked.
