The Peruvian diving petrel Pelecanoides garnotii is endemic to the Peruvian or Humboldt Current. Descriptions of past colonies suggest that the species was once abundant in Peru, but harvesting guano on its nesting islands and killing the birds for their meat caused a drastic decline in the population. Fishing activities and direct exploitation threaten the only two remaining breeding colonies in Peru. There are an estimated 4000 breeding individuals left, but unless they are protected the species will continue to decline.
