'Deafening' nighttime sounds heard echoing on remote Georgia island. What causes them? Mark Price, The Charlotte Observer Mar. 5—Remote Sapelo Island off the Georgia coast has been called everything from "haunted" to "cursed" — and a video shared days ago on Facebook shows it's every bit as spooky as you'd imagine. Filmed at night, the brief clip is largely pitch black, except for a shadowy outline of a ragged tree canopy on the horizon. But that's not the creepy part. It's the noise: a guttural chorus of chittering, rattling and croaks in the dark. The 15-second video was posted Feb. 27 by Georgia's Wildlife Resources Division, which noted heavy rain and warm temperatures on the barrier island had given rise to "vocalizing at a deafening volume."
