Population justification: In Peru, there were c.12,000-13,000 pairs on San Gallán and La Vieja Islands in 1995-1996 Jahncke and Goya (1998); these numbers are supplemented by additional, though small, colonies off Chile.
Trend justification: The species is detrimentally affected by a number of threatening processes: guano extraction and exploitation for food, predation by introduced rats and dogs on breeding islands, incidental bycatch at sea and increasing frequency of El Niño Southern Oscillation events.
