In 1863 the island was estimated to have guano deposits of almost 7 million metric tons,[2] which were then exploited without any control. The number proved to be an overestimate[2] and today that wealth has almost disappeared and the little remaining guano does not have the same quality as before.
The climate of this island is very warm and is home to birds like kelp gulls,[3] boobies (Blue-footed, Nazca, and Peruvian),[4][5] and Guanay cormorants.[4] The last two species were of great importance during the heyday of guano. Lobos de Tierra Island owes its name to its proximity to the coast and the presence of otariids. At times blue whales can be seen.[6]
Around the island there are several islets such as El León and Albatros.
An 1863 survey of the islands north of Lima identified 6.8 million metric tons of phosphatic guano on Isla Lobos de Tierra alone. All of those proved to be gross overestimates.
The subantarctic Dominican or Kelp Gull (Larus dominicanus) is an even more remarkable invader, for it finds centres of maximum abundance, as a nesting bird, at localities so utterly unlike as the Strait of Magellan and Lobos de Tierra Island.
The Blue-footed Booby has a relatively wide breeding range -- from the Gulf of California, the Gulf of Panama (population ca 100 pairs, pers. obs.), the Galápagos, and southward to its overlap with the Peruvian Booby on Isla Lobos de Tierra, Peru.
