Humboldt penguin
As of August 2018, the species is listed as Vulnerable on the IUCN Red List, noting a declining population of 32,000 mature adults. Climate change, commercial overfishing of main prey species (sardines and anchovy) and bycatch in commercial and artisanal fisheries are all contributing factors in the species' decline. Rats, feral cats and dog attacks threaten some colonies. Historically, the Humboldt penguin population was impacted by the extraction of guano from their breeding colonies, which reduced the available habitat for burrowing and nesting.
