Population justification: Brooke (2004) estimated the global population to number at least 15,000,000 individuals. A minimum of 5,000,000 pairs are thought to breed at Tristan da Cunha, and 600,000 to 3,000,000 pairs at Gough (Carboneras 1992d).
Trend justification: The population is suspected to be stable in the absence of evidence for any declines or substantial threats.
