GEOGRAPHY THROUGH MAPS

Peruvian guano coast

Peru’s coastal islands and headlands support seabird colonies nourished by productive nearby waters. Accumulated bird droppings, or guano, have long been used as fertiliser.

Fast Facts

  • The guano islands and headlands lie off Peru’s dry Pacific coast.
  • Anchoveta and other fish connect plankton production to seabirds.
  • Aridity helps guano accumulate by limiting rain-driven loss of nutrients.
