Oct. 4 Four days otit of Oahu, - Gilbert-Marshalls 
Two individuals, possibly Peale’s Petrels were 
seen by Huber and myself, one at 0830 and .one 
at 0855. The one seen at O83O 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 reminescent 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 unperparts, grayish 
black on abdomen, white towards undertail area, 
with a Bonin type underwing. 
Of the 975 Sooty Shearwater seen today 886 
( %) were seen in a total of 31 flocks.
