Red-footed Booby 
A total of n r ine were seen in the grid, only two of which were adults. 
All birds sighted were on days when the cruise tract was closest to Johnston 
Atoll (within 180 miles), but no orange streamers were seen. 
The fact that over 85$ of the birds were subadults is interesting. This 
data, along with previously collected data, would tend to indicate that during 
November the subadult and immature birds have a greater tendency to wander at 
sea than do the adults. 
The significantly larger grid population this year (as compared to November 
1965 ) probably reflects a better food supply, but could result from some other factor. 
Great Frigatebird 
A total of 24 Frigates was seen in the grid. Of these, 13 were identified 
as Great Frigates while the remainder were identified sc s Frigate species, but 
were quite probably Great Frigates. 
The November distribution of this species within the grid does not appear 
to be random. Over 90$ were in the western and northern quadrants, or west of 
171 degrees west longitude. In this area, where mixed feeding flocks were most 
numerous, over 50$ of "the Frigates sighted were in feeding flocks. Single 
birds were often noted chasing flying fish. 
Ages (when noted) included three Immatures and eight adults. 
Sooty Tern 
A total of 51 Sooties (42 during the day and 9 at night) was observed in 
the grid this month. This is a considerably lower number than last year (122) 
despite the fact that more hours of nocturnal observation were conducted this 
November. 
All of the diurnal sightings of Sooties were west of 172 degrees longitude 
and with the exception of a single adult, were all in feeding flocks. The un¬ 
questionable identification of one immature is interesting. 
During nocturnal observations small numbers of Sooties were seen throughout 
the grid area. As stated before, none were seen east of 172 longitude during the
