Justification of Red List Category
This species has an extremely 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.
Brooke (2004) estimated the global population to number around 5,000,000 individuals.
The population is suspected to be stable in the absence of evidence for any declines or substantial threats.
The Fairy Prion is found throughout oceans and coastal areas in the Southern Hemisphere. Their colonies can be found, amongst other places, on the Chatham Islands, Snares Islands and Antipodes Islands of New Zealand, the Bass Strait Islands of Australia, the Crozet Islands (French Southern Territories) in the south Indian Ocean and the Falkland Islands (Islas Malvinas) and South Georgia (Georgia del Sur) in the south Atlantic (del Hoyo et al. 1992).
This marine species apparently occurs mainly offshore, but may move inshore during stormy weather. Its diet is comprised mostly of crustaceans (especially krill), but occasionally includes some fish and squid. It feeds mainly by surface-seizing and dipping, but can also catch prey by surface-plunging or pattering. It often associates with other prions and storm-petrels when feeding around boats. The breeding season starts in September and the species is highly colonial, creating burrows in coastal sites on oceanic islands (del Hoyo et al. 1992).
Although the Fairy Prion is not thought to be experiencing any significant threats across the majority of its range, the population in the Kerguelens suffers ongoing predation from cats.
