The site was identified as important in 2019 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 List1	Season	Year(s)	Size	IBA criteria
Humboldt Penguin Spheniscus humboldti	VU	resident	2003	370 individuals	B3a
Peruvian Diving-petrel Pelecanoides garnotii	NT	breeding	2003	1,550 breeding pairs	A1, A4, B3a
Peruvian Pelican Pelecanus thagus	NT	non-breeding	2009	87 individuals	A1
Peruvian Pelican Pelecanus thagus	NT	resident	2015-2019	3-93 individuals	B1a

Red-legged Cormorant Poikilocarbo gaimardi	NT	resident	2015-2019	6-201 individuals	B1a
Guanay Cormorant Leucocarbo bougainvilliorum	NT	resident	2009-2010	422-500 individuals	A1
Guanay Cormorant Leucocarbo bougainvilliorum	NT	resident	2015-2019	14-2,155 individuals	B1a

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2019) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2019. The most recent assessment (2019) is shown below.

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Marine Coastal/Supratidal	-	good (> 90%)	favourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Invasive and other problematic species and genes	happening now	majority/most of area/population (50-90%)	moderate to rapid deterioration	high
Climate change and severe weather	likely in short term (within 4 years)	whole area/population (>90%)	slow but significant deterioration	high
Pollution	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Biological resource use	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Human intrusions and disturbance	happening now	small area/few individuals (<10%)	no or imperceptible deterioration	low

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Whole area of site (>90%) covered by appropriate conservation designation	A comprehensive and appropriate management plan exists that aims to maintain or improve the populations of qualifying bird species	Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity	high

Year	Protected Area	Designation	% overlap with IBA
1990	Pinguino de Humbolt	Reserva Nacional	100
2005	Islas Choros - Damas	Reserva Marina	2

Habitat1	Habitat detail	% of IBA
Shrubland	Arid lowland scrub	90
Marine Coastal/Supratidal		minor (<10)
