There is no actual "Guano Island". There is a Guano Island Act, which is a federal legislation passed by the US Congress on 18 August 1856. It enables US citizens to take possession of islands containing guano deposits. Guano is the droppings of bats, seabirds, and seals. It is a highly prized fertilizer.
Some islands are formed by volcanoes, but most are not.
The Hawaiian Islands are formed by the ocean structures known as submarine volcanoes. They continue to build the Pacific islands.
The Hawaiian Islands were formed by volcanic activity originating from a hotspot in the Earth's mantle beneath the Pacific tectonic plate. As the plate moved northwest over the hotspot, a series of volcanoes formed, creating the islands. As the plate continued to move, new islands formed in the chain, with the oldest islands towards the northwest and the youngest towards the southeast.

The production decline in guano islands was due to overharvesting of the guano, which led to depletion of the resource. Additionally, competition from synthetic fertilizers made from ammonia contributed to the decline in demand for guano. Regulations to protect seabird populations also limited harvesting on some islands.
The Guano Islands Act allowed the United States to claim midway atoll.
