HOWLAND ISLAND GREATER FRIGATE Birds - annotated List 
October 10, 196^-Hackman — Before heading out 
to the ship (at 0900) I watched the large circulating flock 
that has been following the tuna school. The feeding flock 
was composed of Brown Boobies, Blue-faced Boobies, Sooty 
Terns, Red-tailed Tropicbirds, and both species of frigate. 
Chasing by Frigate noted as follows: 
2 female Greater ?? chasing a Brown Booby - no success - this 
chase was of very short duration. 
11 It seems that the Frigate prefer to chase Sooty Terns 
when that species is present. The Booties apparently 
give up their food readily when threatned. Boobies require 
too much flying and manuevering in comparison to the smaller 
meeker terns. " 
October 12, 1964 - Woodward — " (In the area near R.T.T.B. 
nests ) a female Greater Frigate was chasing Blue-faced 
Boobies. Saw two attacks. In the second one the booby 
dropped something in flight which the frigate dropped down 
and pick(ed) it out of mid air with its bill, but it drotmed

Feb. 2, 1905 -- Woodward -- " After returning to.camp I 
wandered down XBXXK* towards the Great Frigate 
colony taking pictures. Although 1 looked right 
at the nest yesterday it didn,t strike me at all 
that there were two young frigates about as big as 
my fist in the same nest. One was a little bigger 
than the other, but they both looked very healthy. 
This is the first time that 1 have seen this.
