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 extremely 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 exceed 12,000,000 individuals.
Population Trend:	Stable

Habitat and Ecology [top]

Habitat and Ecology:	This marine species normally occurs offshore, and can be found in areas of upwelling outside the breeding season. Its diet is comprised mostly of crustaceans, especially krill, but also fish and squid, all of which it catches either by hydroplaning, surface-seizing or filtering. Breeding starts in October in huge colonies up to and above one million individuals strong. It nests in burrows, usually on islands, inland on highland plateaux or on slopes with grass or shrubs. It can also be found in caves or crevices (del Hoyo et al. 1992).
Systems:	Terrestrial; Marine
