R.Clapp 1964 Oct. 4 Four days out of Oahu, - Gilbert-Marshallss Two individuals, possibly Peale's Petrels were seen by Huber and myself, one at 0830 and one at 0855. The one seen at 0830 was seen but poorly by me. It was gray on the back, with gray black on the abdomen, and possessed white under-tail coverts and rear of ventrum. It had a white black bordered underwing like a Bonin Petrel and the flight was reminiscent of that species. The second bird was seen by Bihion Amerson who noted the darkening on the belly. The bird fit the description in Alexander but did not appear that dark dorsally. Light upperparts, grayish black on abdomen, white towards undertail area, and with a Bonin type underwing. Of the 975 Sooty Shearwater seen today 886 ( %) were seen in a total of 31 flocks.
