Abstract: The diets of the Blue-faced Booby (Sula dactylatra), the Red-footed
Booby (Sula sula), and the Great Frigatebird (Fregata minor) were studied by
analyses of reg urgitation samples. Flying fish and squid composed the majority of
the diets, but the Frigatebirds also consumed numerous Sooty Tern (Sterna
fuscata) pulli. These data allow comparison with similar earlier studies of the
smaller bird species that inhabit the atoll and indicate that resource partitioning
occurs through the percentage of fish and squid taken and the size of the prey items
taken, with the larger species of birds eating larger fish and squid.
