Newell Shearwater 27 All but one of these birds were recorded off the south end of Niihau Island. The birds were feeding there in late evening. Christmas Shearwater 2 The two birds were recorded enroute to French Frigate Shoals. As on last June's cruise, no birds were recorded at sea over the western leewards where they are breeding and on eggs at this time. Dark-rumped Petrel 1 Only one bird was positively recorded as this species, near Niihau on 24 May. Bonin Petrel 47 The majority (38) of these birds were recorded 27 May while passing 60 miles offshore of Lisianski Island. Bulwer Petrel 128 Main concentrations were in waters near main Hawaiian Islands. The birds might be breeding here at this time. At-sea numbers are low in western leewards where birds were found on eggs. Leach/Harcourt Storm Petrel 2 These were recorded only as white rumped storm petrels, and belong to one of the above species. Red-tailed Tropicbird 8 The low numbers of tropicbirds recorded might have two possible ex- planations. The birds are normally attracted to larger ships and, like the albatross, do not follow the small ships. Or, the birds were on eggs and spending much of the daytime courting over the islands, thus limiting their pelagic movements. Blue-faced Booby 30 Small numbers were recorded throughout the cruise with concentrations near Gardner Pinnacle (a breeding area) and in the vicinity of Kaula Rock off Niihau. Brown Booby 18 Only one bird was recorded in the western leewards. The remaining 17 birds were recorded on 14 June in the vicinity of Niihau. Red-footed Booby 69 The most abundant booby recorded, because of the 55 observed on 14 June, near Niihau. Great Frigate 29 Seen in small numbers throughout the entire survey. They were generally associated with feeding flocks. Pomarine Jaeger 6 All observed offshore of Oahu on 23 May.
