General Summary 
Numbers for May totalled 9185, considerably higher than previous 
months. Excepting 51 May, the last day of the cruise ; numbers were 
rougnly comparable with May 1964. However, on 51 May record 
numbers (VfSl) and flocks (25) were encountered just north of Oahu. 
These flocks were comprised mainly of Sooty and Noddy Terns, both of 
which reached record numbers. The area of greatest density was, of 
course, just north of Oahu, but numbers were considerably higher 
than usual up to 500 miles north and east of the high Hawaiian 
Islands. A small secondary density center in the southern portion 
of the area was due to the influx of Juan Fernandez and Cook's Petrels 
from the south. 
Of interest were the following sightings: a Mottled Petrel, 
5 Kermaaec Petrels, 16 Dark-rumped Petrels, at least 2 Long-tailed 
Jaegers, a Skua, 7 Arctic Terns, and the first at sea record of a 
Wandering Tattler. 
Io is felt that there is a connection between the very large 
and numerous flocks seen near Oahu and the fact that Oahu Skipjack 
Tuna fishermen are experiencing a record catch this summer. 
The data gathered appear to be comparable with those of previous 
months.
