Red-footed Booby 
Red-foots were observed to feed slmost exactly like Browns* They both

sat on the water and dabbled and also flew over the water until a fish or other 
food was spotted and then dove almost vertically into the water* 
Feeding Flock Structure 
* * 
% 
In the flocks observed, each species seemed to consistently occupy the 
same position within the flock* Frigatebirds for example stayed above the 
main feeding flock — often 200 yards above the flock* In one flock frigates 
' • 
were observed to come down to the level of the other species* Sooty and Fairy 
V - i , 
r ^ • 
Terns stayed above the flock but were constantly diving down to the water and 
coming back up above the other birds. Common, Hawaiian and Blue-gray Noddies 
stayed just above the wster surface following the fish school very closely. 
Wedge -tailed and Newell's Shearwaters were observed to follow the action of 
the terns but also flew around the area, neither staying up with the terns 
nor the fish school. Both species of booby flew all over the areal some- 
times flying up with the Sooty and Fairy Terns; other times flying lower with 
the various Noddies.
