The site was identified as internationally important for bird conservation 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 List	Season (year/s of estimate)	Size	IBA criteria
Humboldt Penguin Spheniscus humboldti	VU	resident (2003)	370 birds	B3a
Peruvian Diving-petrel Pelecanoides garnotii	NT	breeding (2003)	1,550 pairs	A1, A4, B3a
Peruvian Pelican Pelecanus thagus	NT	non-breeding (2009)	87 birds	A1
Peruvian Pelican Pelecanus thagus	NT	resident (2015–2019)	3–93 birds	B1a
Red-legged Cormorant Poikilocarbo gaimardi	NT	resident (2009)	53 birds	A1
Red-legged Cormorant Poikilocarbo gaimardi	NT	resident (2015–2019)	6–201 birds	B1a
Guanay Cormorant Leucocarbo bougainvilliorum	NT	resident (2009–2010)	422–500 birds	A1
Guanay Cormorant Leucocarbo bougainvilliorum	NT	resident (2015–2019)	14–2,155 birds	B1a
Grey Gull Larus modestus	LC	non-breeding (2015–2019)	15–38 birds	A3
Inca Tern Larosterna inca	NT	resident (2015–2019)	2–156 birds	A3, B1a
Seaside Cinclodes Cinclodes nigrofumosus	LC	resident (2015–2019)	3–33 birds	A3

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%)	good

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Invasive and other problematic species and genes	happe­ning now	most of popul­ation/area (50–90%)	moderate decline (10–30% over 3 gener­ations)	high
Climate change and severe weather	likely in short term (<4 years)	whole of popul­ation/area (>90%)	slow decline (1–10% over 3 gener­ations)	high
Pollution	happe­ning now	some of popul­ation/area (10–49%)	slow decline (1–10% over 3 gener­ations)	medium
Biological resource use	happe­ning now	some of popul­ation/area (10–49%)	slow decline (1–10% over 3 gener­ations)	medium
Human intrusions and disturbance	happe­ning now	few indivi­duals/small area (<10%)	no or slight decline (<1% over 3 gener­ations)	low

Response (conservation actions taken for the trigger species and/or their habitats)
Designation	Planning	Action	Result
Whole area (>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 (management category)	% coverage of IBA
1990	Pinguino de Humbolt	Reserva Nacional (IV)	100
2005	Islas Choros - Damas	Reserva Marina (IV)	2

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

Land use	% of IBA
nature conservation and research	major (>10)
