Treasure Island installs sea turtle-friendly lights in time for hatchling season Catherine Hawley reports TREASURE ISLAND, Fla. - This weekend marks the start of sea turtle nesting season along the beaches in the Sunshine State. Thanks to new lights being installed in Treasure Island, hatchlings should have an easier time finding their way around the beach in Pinellas County. After hatching from their nests on the beach, sea turtles rely on moonlight to find their way to the water. Bright lights from beachside businesses, housing, and the street can disorient the baby turtles, causing them to crawl the wrong way.
