Data Zone
The site was identified as internationally important for bird conservation in 2010 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 |
|---|---|---|---|---|
| Juan Fernandez Firecrown Sephanoides fernandensis | CR | resident (2005) | present | A1, A2, A3 |
| Masatierra Petrel Pterodroma defilippiana | VU | breeding (2008) | present | A1 |
| Pink-footed Shearwater Ardenna creatopus | VU | breeding (2008) | 7,000–80,000 pairs | A1, A4ii |
| Juan Fernandez Tit-tyrant Anairetes fernandezianus | EN | resident (-) | present | A1, A2, A3 |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2010. The most recent assessment (2017) is shown below.
