Range Description

Sterna virgata breeds in the southern Indian Ocean on the Prince Edward Islands (South Africa) (10-40 pairs on Marion Island during 1996-1999, 12-56 pairs during 1998-2009 without any apparent trend [Whittington et al. 2009], 20 pairs on Prince Edward Island [Barnes 2000] although only a single nest located in 2008 survey [Whittington et al. 2009]), Crozet Islands (French Southern Territories) (150-200 pairs over 1980-1982) and Kerguelen Islands (also French Southern Territories) (1,000-2,000 pairs during 1982-1985). The total population is estimated at 3,500-6,500 individuals (Jouventin et al. 1988, Thibault and Guyst 1993). There are no recent counts from the main breeding area on Kerguelen (V. Bretagnolle in litt. 1999) and thus population trends are unknown, but it is assumed that the species is not undergoing any significant decline.
