Data Zone
The site was identified as internationally important for bird conservation in 2011 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 |
|---|---|---|---|---|
| Band-rumped Storm-petrel Hydrobates castro | LC | breeding (2007) | min 100 pairs | B1ii, B2, C2, C6 |
| Audubon's Shearwater Puffinus lherminieri | LC | breeding (2007) | min 5 pairs | B2, C6 |
| Bulwer's Petrel Bulweria bulwerii | LC | breeding (2007) | 300–400 pairs | B1ii, B2, C2, C6 |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2011. The most recent assessment (2008) is shown below.
