Population justification: The most recent population estimate places it at 100,000-1,000,000 individuals. |
|
Trend justification: It is likely to have been as badly affected by the El Niño event of 1998 as other Humboldt Current species such as Inca Tern Larosterna inca, and although the population is thought to be increasing (Wetlands International 2006), declines over 36 years (three generations) are thought to have been in the region of 10-19%. |
