It hunts for fish (including flying fish) in the shallow water of the lagoons or at sea but rarely more than 1 to 2 km away from the coast.

The nests are simple hole in the sand a few meters from the shore, and very close to each other. Reproduction is studied outside French Polynesia. A grey egg (61 x 41 mm) is incubated for 25-26 days by both sexes. Chicks, once aged of 15 days, gather in nurseries, and are able to swim to escape danger.
