Thanks to the Guanay cormorants, a native bird species, the islands are very rich in guano, a fertilizer composed (among other things) of their poo. This made the islands a potentially valuable—if somewhat smelly—asset to all involved. One of the outcomes of this particular war was Spain's recognition of Peruvian independence.
