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 |
---|---|---|---|---|
Grey Gull Larus modestus | LC | non-breeding (2008) | 4,000 birds | A4i |
Franklin's Gull Larus pipixcan | LC | non-breeding (2001) | min 10,000 birds | A4i |
Belcher's Gull Larus belcheri | LC | non-breeding (2001) | 50–800 birds | A4i |
Inca Tern Larosterna inca | NT | breeding (2008) | 100 birds | A1 |
Elegant Tern Thalasseus elegans | NT | non-breeding (2008) | 700 birds | A1 |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2010. The most recent assessment (2015) is shown below.
