lack of birds. Perhaps the numbers along the northern leg were swelled by birds 
from the Leeward chain and the birds present on the Hawaiian Islands this time 
of year do not range very far from land. This seems reasonable since most adult 
Sooty Terns and Wedgetailed Shearwaters have left by October. 
The data for October 10 are representative of observations around atolls, 
as discussed later, rather than of the open ocean. They are included in this 
section, however, as they also are similar to observations in the immediate 
vicinity of Oahu, showing the increase in avian numbers with proximity to land.

One individual of this species was seen, on November 27, about JO miles 
off Oahu.

Nearly twice as many were seen in October as in November. Concentrations 
were found within 60 miles of Oahu in both months and just south of Johnston 
Atoll on the return track. Population density was three times greater around 
Oahu in October. Numbers fell off sharply beyond 200 miles from Oahu in 
November, whereas in October relatively constant numbers were recorded south 
of the Hawaiian chain to 175° but then decreased suddenly. Of birds not in 
flocks for which flight direction was recorded, nearly twice as many were 
moving in a southerly direction as to the north. These data are consistent 
with a southerly movement from the nesting areas at the conclusion of the 
•breeding cycle*but suggest a leisurely dispersal rather than a rapid directional 
migration.
