Data Zone
The site was identified as internationally important for bird conservation in 2021 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 |
|---|---|---|---|---|
| Lilac-crowned Amazon Amazona finschi | EN | resident (2011) | 247 birds | A1 |
| Thick-billed Parrot Rhynchopsitta pachyrhyncha | EN | resident (2011) | 32 birds | A1 |
| Orange-fronted Parakeet Eupsittula canicularis | VU | resident (2011) | 36 adults | A1 |
| Military Macaw Ara militaris | VU | resident (2015) | 103 birds | A1 |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2021. The most recent assessment (2023) is shown below.
