The decline in numbers of this species in June is accounted for mainly by the relative paucity of dark phase birds in the southern part of the gird. The dark phase birds also penetrated farther north than pre- viously reported, to 17°N, and were distributed more diffusely. Two of this species were collected. One, taken 150 miles north of Oahu on 1 July, was banded on Popoia Island, Oahu on 8 May 64. Sooty Shearwater One of this species was seen on 25 June heading northwest, no doubt a straggler, since this species' northward migration ended a month previous to this date. Newell's Shearwater Numbers of this species decreased 77% from 66 in May to 15 in June, presuming a concentration of this species more local to its nesting areas. Bonin Island Petrel Numbers of this species increased 155% from 69 in May to 176 in June. Molt was noted in more than 80% of these birds. The species
