Although this species may have a restricted range, it is not believed to 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 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.

Geographic Range [top]

Range Description:About 90% of the known breeding population is concentrated in the Faroe Islands (Denmark; 150,000-400,000 pairs), United Kingdom (20,000-150,000 pairs), Ireland (50,000-100,000 pairs) and Iceland (50,000-100,000 pairs), with smaller colonies in France (400-600 pairs), Greece (10-30 pairs), Italy (1,500-2,000 pairs), Malta (5,000 pairs), Norway (1,000-10,000 pairs), Spain (1,700-2,000 pairs) and a further 1,000 pairs on the Canary Islands, Spain. The species winters off western and southern Africa.

Population [top]

Population:In Europe (which covers >95% of the breeding range), the breeding population is estimated to be 430,000-510,000 breeding pairs, equating to 1,290,000-1,530,000 individuals (BirdLife International 2004); Brooke (2004) also estimated the total population to number around 1,500,000.

Trend Justification:  The population is suspected to be in decline owing to predation by invasive species, pollution and development of breeding sites.
Current Population Trend:Decreasing
Additional data:
Continuing decline of mature individuals:Unknown
Extreme fluctuations:NoPopulation severely fragmented:No
Continuing decline in subpopulations:Unknown
Extreme fluctuations in subpopulations:NoAll individuals in one subpopulation:No

Habitat and Ecology [top]

Habitat and Ecology:This is a marine species feeding mainly on small fish, squid and crustaceans, but it will also feed on medusae and offal. It feeds mainly on the wing by pattering and fishing, and will occaisionally follow ships and attend trawlers. Breeding starts in May and June, resulting in the formation of colonies on rocky ground on offshore islands and stacks that are largely free of mammalian predators (del Hoyo et al. 1992).
Systems:Terrestrial; Marine
Continuing decline in area, extent and/or quality of habitat:Unknown
Generation Length (years):15.7
Movement patterns:Full Migrant
Congregatory:Congregatory (and dispersive)

Threats [top]

Major Threat(s): The accidental introduction of predators is the main threat to this species, particularly in southern Europe and the Mediterranean. In some areas, increases in numbers of skuas and large gulls appear to have increased the rate of predation. There may be some risk from eating contaminated food items or taking indisgestible matter but, by feeding in flight, the species is less vulnerable to oil spills than some other seabirds (Newbury et al. 1998, Tucker and Heath 1994).
