Blue-faced Booby 
Numbers are nearly identical with those of 1963 and 1961*• Two 
immatures were collected, one in the grid# The one collected to the 
north weighed much less (600 grains) than the other, similar to the 
Red-tailed Tropicbirds. 
Red-footed Booby 
This species appears to be very variable in numbers from month to 
month and year to year# About as many were recorded outside the grid this 
month as in October 1961* and November 1963# Only one was seen within the 
grid this month, a subadult on November 16 about 130 miles SW of Johnston# 
Of the 12 present outside the grid, 5 were recorded as immatures and 2 as 
subadults# Five occurred within 30 miles of Oahu and five more were within 
250 miles of Oahu and Kauai# 
One adult which flew aboard after dark November 8 was captured, 
blood-sampled and released# 
Brown Booby 
« 
Two immatures were seen outside the grid# One occurred about 21*0 miles 
SW of Oahu# The other about 180 miles east of Johnston# 
Greater Frigatebird 
As with the Red-footed Booby, no definite pattern is discernible from 
year to year in the occurrence of this species this month except that the 
largest numbers are recorded at this season# Nearly twice as many were 
present in the grid as in 1961*# Non-grid numbers were comparable to those 
of 1963•
