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 |
|---|---|---|---|---|
| Short-crested Coquette Lophornis brachylophus | CR | resident (2020–2021) | 29 birds | A1 |
| White-tailed Hummingbird Eupherusa poliocerca | NT | resident (2019) | 56 birds | A1 |
| Lilac-crowned Amazon Amazona finschi | EN | resident (2018) | 109 birds | A1 |
