Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2016
Date Assessed: 2016-10-01

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.

Geographic Range [top]

Range Description:The breeding range of Wilson's Storm-petrel includes subantarctic islands from Cape Horn (Chile) east to the Kerguelen Islands (French Southern Territories), and also includes coastal Antarctica. It undergoes trans-equatorial migration, spending the off-season in the middle latitudes of the north Atlantic and north Indian Ocean. A lower number of individuals also migrate to the Pacific.

Population [top]

Population:Brooke (2004) estimated the global breeding population to number 4,000,000-10,000,000 breeding pairs, equating to 12,000,000-30,000,000 individuals.

Trend Justification:  The population is suspected to be stable in the absence of evidence for any declines or substantial threats.
Current Population Trend:Stable
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:Wilson's Storm-petrel breeds on rocky islets, on cliffs and amongst boulder scree. It prefers to feed mainly in cold waters over continental shelves or inshore, with a diet of comprised mainly of planktonic crustaceans (especially krill) and fish (del Hoyo et al. 1992). Its diet shifts from mainly crustaceans during egg formation to an increased proportion of fish during chick-rearing and moulting (Quillfeldt et al. 2005).
Systems:Terrestrial; Marine
Continuing decline in area, extent and/or quality of habitat:Unknown
Generation Length (years):15.6
Movement patterns:Full Migrant
Congregatory:Congregatory (and dispersive)
