The site was identified as important in 2021 because it was regularly supporting significant populations of the species listed below, meeting ('triggering') IBA criteria.

Populations meeting IBA criteria ('trigger species'):

Species	Current IUCN Red List Category	Season	Year(s)	Population estimate at site	IBA criteria met
Short-crested Coquette Lophornis brachylophus	CR	resident	2020-2021	29 individuals	A1
White-tailed Hummingbird Eupherusa poliocerca	NT	resident	2019	56 individuals	A1
Lilac-crowned Amazon Amazona finschi	EN	resident	2018	109 individuals	A1
Orange-fronted Parakeet Eupsittula canicularis	VU	resident	2018	35 individuals	A1

The current IUCN Red List category may differ from that which was valid at the time of IBA criteria assessment (2021).
