Site description:

Located approximately half-way between St. Kitts and Nevis, uninhabited Booby Island is a mix of dense, brushy vegetation and rocky outcroppings. The shoreline of this circular islet is composed of large rocks which almost immediately meet a steep hillside.

Summary of threats to biodiversity at KBA:

Booby Island is unprotected and appears to be the property of the Federation. There is no easy boat access to the island; visitors must swim onto the rocks. Fisherfolk are reported to collect seabird eggs at this site, especially those of Laughing Gulls. No mammals were recorded during the one survey of the island.
