Population justification: In Peru, there were c.12,000-13,000 pairs on San Gallán and La Vieja Islands in 1995-1996; these numbers are supplemented by additional, though small, colonies off the coast of Chile.

Trend justification: The species is detrimentally affected by a number of processes including 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.
