Data Zone
The site was identified as internationally important for bird conservation in 2020 because it was regularly supporting significant populations of the species listed below, meeting ('triggering') IBA criteria.
Populations meeting IBA criteria ('trigger species') at the site:| Species | Red List | Season (year/s of estimate) | Size | IBA criteria |
|---|---|---|---|---|
| Pink-footed Shearwater Ardenna creatopus | VU | breeding (2016–2020) | 300–2,000 birds | A1, A4 |
| Peruvian Pelican Pelecanus thagus | NT | resident (2016–2020) | 25–1,500 birds | B1a |
| Red-legged Cormorant Poikilocarbo gaimardi | NT | resident (2016–2020) | 20–400 birds | B1a |
| Elegant Tern Thalasseus elegans | NT | non-breeding (2016–2020) | 10–350 birds | B1a |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2020. The most recent assessment (2014) is shown below.
