McKean Island Sanctuary (Kiribati)

Weather…

McKean Island Sanctuary is a remote coral atoll located in the Phoenix Islands and is a critical component of the Phoenix Islands Protected Area (PIPA), a UNESCO World Heritage site. This uninhabited island features a shallow central lagoon that often dries out during low tide, surrounded by resilient coral reefs. Its global conservation significance lies in its role as one of the world's premier nesting grounds for Great Frigatebirds. Thousands of these seabirds, alongside sooty terns and petrels, congregate here annually to breed in the low-lying scrub vegetation. Because there are no permanent human residents or invasive predators, the island remains a pristine sanctuary for avian life. The surrounding waters are equally animated, boasting exceptionally healthy coral structures and a high density of reef fish, sharks, and sea turtles. Access to McKean is strictly controlled to preserve its delicate ecological balance, making it a vital reference site for scientists studying marine biodiversity and the impacts of global climate change in an undisturbed Pacific environment.
