Justification:
This species has a very large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size is very large, and hence does not approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

Habitat and Ecology [top]

Habitat and Ecology:	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 sites (del Hoyo et al. 1996).
Systems:	Terrestrial; Marine
