It is likely that the increase in numbers away from islands at this 
time of year is due to birds having to range farther for food* Several 
birds were actively feeding by themselves. It is not known to what extent 
this depends upon the absence of concentrations of the abundant breeding 
species near the islands, in terms of what proportion of the frigate 
populations preys upon these species and what proportion of individual 
frigate*s total food is pirated from other species. 
Golden Plover 
Numbers were more comparable with 1963 than 1961*, supporting the 
view that the Slender-billed Shearwater migration also paralleled 1963* 
Two individuals were collected between Oahu and the grid* Neither 
was molting. Many circled the ship several times, one landing after dark 
on November 17 which avoided capture. 
Ruddy Turnstone 
The single sighting was obtained on November 22, about 175 miles 
W of Oahu. 
Sooty Tern 
Total numbers were nearly identical to those of 196U but the results 
in the grid more closely resemble 1963. 
Outside the grid birds were encountered between 160° and 165 , to the 
east and northeast of Johnston Atoll. The decline from 1*0* per day on 
November 9 and 10 to about 30 per day on November 21 and 22 may reflect 
the departure of birds from the area, though it may be too small a difference
