Archive images were projected into contemporary scenes on Peru’s Guano Islands, where the seabird population that declined dramatically as a result of 19th-century guano harvesting is now beginning to recover. Guano, the nitrate-rich droppings of birds such as pelicans, boobies and cormorants, became popular as a fertilizer in the 19th century, and Peru’s Guano Islands were a prime source. The boom ended with the introduction of ammonia-based chemical fertilizers in the early 20th century, but the bird populations had nosedived. Today, guano mining is much less frequent, rotates location, and is supervised by conservationists, allowing some of Peru’s seabird populations to recover. The archive photographs were taken by the marine biologist Robert E. Coker, who began working in Peru in 1906.
