Huanu Islands

Off Pisco, the Chincha and Ballestas islands rise from the cool waters of the Humboldt Current. Peruvian boobies, guanay cormorants and other seabirds feed in this productive sea and nest on the dry islands. Their accumulated guano was valued as fertiliser by the people of the Chincha valleys before the Inca conquest. Boats carried this resource from the islands to fields on the arid mainland.
