evidence: Also known as the Petrel Islands, Bajo Nuevo Bank is a 15-mile-long reef with some grassy island outcrops in the otherwise open Caribbean Sea, midway between Jamaica and Central America. It was claimed by the US in 1869, under the Guano Islands Act. Though most of the islands in the region claimed by this act were renounced by the USA in a 1972 treaty with Colombia, this atoll-like structure, as well as another, Serranilla Bank, 70 miles west, were not mentioned by name, unlike the others, so they continued to be claimed as Territories of the USA, though not aggressively so. Bajo Nuevo Bank has also, over the years, been claimed by Honduras and Jamaica – though Jamaica seems to have backed off since the 1980s. Nicaragua, however, still makes a claim that the Bajo Nuevo Bank is within its territorial waters, and therefore belongs to it. An international court ruling in 2012 found that Colombia has sovereignty over Baja Nuevo Bank, as well as the nearby Serranilla Bank, though the US does not recognize the ruling.
