Cephalopods, small fish including flying fish.
Breeds in colonies. A pale pink egg with red spots (53 x 36 mm) is incubated for 34 days by both sexes. The adults remain near the young for the first days after hatching. The chick remains in the nest for about 35 days then the parents feed the young until 100 days after fledging. The species is sometimes consumed by man in French Polynesia. Chicks are also victims of the Great Frigatebird Fregata minor. These birds breed all year round in the Marquesas, from September-October to May to June elsewhere.
