Data Zone
The site was identified as important in 2020 because it was regularly supporting significant populations of the species listed below, meeting ('triggering') IBA criteria.
Populations meeting IBA criteria ('trigger species'):| Species | Current IUCN Red List Category | Season | Year(s) | Population estimate at site | IBA criteria met |
|---|---|---|---|---|---|
| Pink-footed Shearwater Ardenna creatopus | VU | breeding | 2016-2020 | 300-2,000 individuals | A1, A4 |
| Peruvian Pelican Pelecanus thagus | NT | resident | 2016-2020 | 25-1,500 individuals | B1a |
| Red-legged Cormorant Poikilocarbo gaimardi | NT | resident | 2016-2020 | 20-400 individuals | B1a |
| Elegant Tern Thalasseus elegans | NT | non-breeding | 2016-2020 | 10-350 individuals | B1a |
The current IUCN Red List category may differ from that which was valid at the time of IBA criteria assessment (2020).
