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 ( 58 ) 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/fcarcourt 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.
