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). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to 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. |

| Population: | Brooke (2004) estimated the global population to approach 1,000,000 individuals. |
| Habitat and Ecology: | This species rarely approaches land except at colonies, feeding mostly at night on a diet predominately comprised of fish, as well as some squid, shrimps and sea skaters. It breeds on oceanic islands, creating burrows in areas of sandy soil or high sloping ground up to 918 m, usually amongst vegetation. Breeding starts in December, with individuals forming dense colonies1. |
