Oahu . "Offshore" Oahu is often best considered to be as much 
0 miles from shore. During the winter months, January to March, the im- 
vicinity of Oahu is sometimes barren of many of the typically 
nearsue 
pelagic species as well as of breeding birds. Pomarine Jaegers and Black' 
footed Albatross were the most conspicuous birds, following ships from 5 
or 10 miles out of the harbor to 50-75 miles (jaegers) or 300-400 miles 
(Alba-cross). Sooty Terns, Red-footed Boobies, and Common Noddies were 
sporadically observed in small flocks. In spite of regular coverage of 
the waters south of Oahu, surprisingly little information is on hand. 
Kingman Reef 15 March • 
% 
Kingman Reef was briefly surveyed from a small vessel. A number of 
Brown Boobies were found roosting on the tiny bit of dry land present. Red- 
x'ooted Boobies, Sooty Terns, and Common Noddies were seen all about the 
Reef area where many small feeding flocks were present. 
Palmyra Island 15 and 18 March 
Between 0 and 10 miles offshore, approximately the following composi¬ 
tion of birds was, found: 
Sooty Tern 80$ , . 
Rea-footed Booby 13$ v \ x 
White-capped Noddy 5$ 
Common Noddy . 1$ 
White Tern l/2$ 
Blue-faced Booby l/4$ 
3rown Booby 1/4$ 
100$ (Based on 1000+ birds) 
While Brown Boobies are fairly common in the interior lagoons, few 
were found in the offshore waters. Blue-x'aced Booby immatures were pres¬ 
ent in low numbers. No breeding location of Blue-faced Booby was found 
during the island survey, but it was thought that a x'ew bred on the far 
eastern shore which was not covered.While the breeding population of 
W r nite-capped Noddy was estimated at a fairly high figure (ca. 20,000) rela¬ 
tively few ventured far from the island. Several large (300+) bird flocks, 
chiefly Sooty Terns, were observed south of the island. To the noruh 
flocks seemed smaller. The large feeding flocks were composed of all the 
major breeding species, roughly in the proportions given above. 
Washington Island 19 March 
M. Thompson and R. Chandler approached to within one mile of the 
southwestern end of the island around noon of the 19 th aboard a small ves¬ 
sel. Due to high surf and schedule delays no attempt was made mo land a 
survey party. At the same time, offshore observations were also being 
uaken from the large vessel located some four miles to the west of the is¬ 
land. The following birds were recorded by one or both parties:
