The site was identified as internationally important for bird conservation in 2012 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 |
---|---|---|---|---|
Red-tailed Tropicbird Phaethon rubricauda | LC | breeding (1973–2007) | 2,500 birds | A4ii |
Polynesian Storm-petrel Nesofregetta fuliginosa | EN | breeding (1973–2007) | 3 birds | A1 |
Lesser Frigatebird Fregata ariel | LC | breeding (1973–2007) | 4,000 birds | A4ii |
Brown Booby Sula leucogaster | LC | breeding (1973–2007) | 2,000 birds | A4ii |
Masked Booby Sula dactylatra | LC | breeding (1973–2007) | 7,000 birds | A4ii |
Blue Noddy Anous ceruleus | LC | breeding (1973–2007) | 650 birds | A4i |
Sooty Tern Onychoprion fuscatus | LC | breeding (1973–2007) | 1,000,000 birds | A4ii |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2012. The most recent assessment (2012) is shown below.
