Sea turtles
Loggerheads haul out of the Atlantic on summer nights to nest on the island's beaches, and the whole island rearranges itself around them.
Bald Head’s beaches are one of North Carolina’s busiest sea-turtle nurseries, and loggerheads do most of the nesting. A mother crawls up past the tide line on a summer night, digs with her rear flippers, lays around a hundred leathery eggs, and disappears back into the surf before sunrise, leaving a track like a tractor tire.
The Bald Head Island Conservancy has monitored every nest on the island for decades: marking them, moving the ones laid too close to the water, and sitting with them at hatch time. In season you can join a guided turtle walk and, with luck, watch a boil of hatchlings scramble for the moonlit surf.
The rules above aren’t bureaucracy; hatchlings navigate by light and open horizon, and a single porch bulb can send a whole nest the wrong way. The island takes it seriously enough to put it on signs at every beach access, and so do we.
