Just off the eastern coast of Ascension Island, Boatswain Bird Island rises from the South Atlantic as a rugged volcanic outcrop alive with seabirds. Though the island covers only about 13 acres, thousands of birds claim its cliffs and slopes each year, turning the rock white with nesting colonies and constant movement.
This small island serves as one of the most important seabird sanctuaries in the region. Red-billed and white-tailed tropicbirds—known locally as “boatswain birds”—wheel above the cliffs that gave the island its name. Masked boobies, black noddies, and petrels gather in dense colonies along the ledges, while Ascension frigatebirds glide overhead on steady ocean winds.
Rugged rock walls drop directly into deep Atlantic waters, and a natural sea arch cuts through the island’s southern shoreline, sculpted by centuries of waves and wind. From the water, the island presents a dramatic profile of dark volcanic stone framed by white seabird colonies and the endless blue of the surrounding ocean.
Despite its modest scale, Boatswain Bird Island plays an important role in protecting Ascension’s birdlife. The surrounding waters and isolated cliffs provide a refuge where seabirds gather, nest, and raise their young in one of the South Atlantic’s most concentrated wildlife habitats.
