In Isla Cozumel, travelers can volunteer to monitor nests and to release hatchlings into the sea. Nesting season runs May-September, and during that period volunteers join biologists on nighttime walks of Cozumel’s beaches, locating and marking new nests, and moving vulnerable eggs to protected hatcheries. From July to November, volunteers release hatchings, typically at sundown, by encouraging the tiny turtles to move toward the water and scaring off birds in search of an easy meal.
