This species inhabits pantropical and subtropical islands, often with small populations dispersed throughout many inshore and oceanic islands. It feeds on small fish and squid, with prey species and proportion of each depending on locality. It often feeds by hover-dipping and contact-dipping. Kleptoparasitism has been observed, and it will associate with other seabirds over schools of predatory fish. Its breeding season varies depending upon locality, with variable colony sizes and nest sites¹.
