 That's a welcome sight for King, a biologist hired by a nearby golf club to help manage the private beach. She's on a three-member survey team taking stock of nest sites for plovers and lease terns, another endangered shorebird. The live chick sightings are particularly encouraging in the wake of powerful storms this winter that tore into Maine's coastline, carving chunks out of beach dunes that plovers call home. Sand movement is natural, says Laura Minik-Zitzke, head of Maine Audubon's coastal bird program. But these storms were different.
